A cash-out refinance can allow homeowners to replace an existing mortgage with a new, larger mortgage and access some of their home equity as cash. The additional funds may be used for home improvements, debt consolidation, education expenses, major purchases, or other financial needs.

However, taking cash out of your home also increases the amount you owe against the property. A higher loan balance, a different interest rate, closing costs, and a new repayment term can all affect the long-term cost of refinancing.

Our Refinance Cash Out Mortgage Calculator is designed to help you estimate the basic numbers involved in a cash-out refinance. By entering your home’s current value, existing mortgage balance, current interest rate, new interest rate, desired cash-out amount, new loan term, and closing costs, you can estimate:

  • New loan amount
  • New monthly mortgage payment
  • Net cash received
  • New loan-to-value (LTV) ratio

These estimates can help you understand a potential refinancing scenario before discussing your options with a mortgage lender.

What Is a Cash-Out Refinance?

A cash-out refinance replaces your existing mortgage with a new mortgage that has a larger balance. The difference between the old mortgage balance and the new loan amount can provide funds that you receive as cash, subject to the lender’s approval and closing costs.

For example, suppose your home is worth $400,000 and your existing mortgage balance is $250,000. If you refinance into a larger loan and take additional equity out, the new mortgage could be substantially higher than your existing balance.

The amount you can actually borrow depends on factors such as:

  • Home value
  • Existing mortgage balance
  • Credit profile
  • Income and debts
  • Lender requirements
  • Loan program
  • Property type
  • Loan-to-value ratio
  • Interest rate
  • Closing costs

The calculator focuses on the mathematical side of the transaction and does not determine whether you qualify for a refinance.

How to Use the Refinance Cash Out Mortgage Calculator

Using the calculator is straightforward. You need to provide seven pieces of information.

1. Enter Your Current Home Value

Start by entering your home’s estimated current market value.

For example, if your property is worth $400,000, enter 400000.

Your home’s value is important because it is used to calculate your new loan-to-value ratio, commonly called LTV.

LTV compares the amount borrowed against the property’s value.

The basic formula is:

LTV = Loan Amount ÷ Home Value × 100

A $300,000 loan on a $400,000 home would result in a 75% LTV.

Your actual home’s value may be determined through an appraisal, automated valuation process, or another method accepted by the lender.

2. Enter Your Current Mortgage Balance

Next, enter the amount you currently owe on your mortgage.

For example, if your current mortgage balance is $250,000, enter 250000.

This amount becomes the starting point for calculating your potential new mortgage.

The calculator assumes the existing mortgage balance will be paid off through the refinance.

If you have multiple liens, a home equity loan, HELOC, or other secured debt, the actual refinancing calculation may be more complicated than the basic calculator model.

3. Enter Your Current Interest Rate

Enter the interest rate on your existing mortgage.

For example:

Current interest rate: 6.50%

This field is included to help you compare your existing mortgage situation with the proposed new rate.

It is important to note that the calculator does not use the current interest rate to calculate the new monthly payment. The new payment is based on the new interest rate you enter.

The current rate is therefore mainly useful for comparing your existing loan with the potential refinance.

4. Enter the New Interest Rate

Enter the interest rate you expect to receive on the new mortgage.

For example:

New interest rate: 5.75%

The new rate directly affects your estimated monthly payment.

A lower interest rate can reduce the payment for a given loan amount, although refinancing into a larger balance can still result in a higher monthly payment than your existing mortgage.

The rate you receive from a lender may depend on credit score, loan-to-value ratio, loan type, property characteristics, market conditions, and other factors.

5. Enter the Cash-Out Amount

Enter the amount of additional cash you want to take from your home equity.

For example, if you want to receive $50,000 before closing costs, enter:

$50,000

The calculator adds this amount to your current mortgage balance.

The basic calculation is:

New Loan Amount = Current Mortgage Balance + Cash-Out Amount + Closing Costs

This means the closing costs entered into the calculator are treated as being financed into the new mortgage.

That distinction is important when interpreting the result.

6. Select the New Loan Term

The calculator provides four loan-term choices:

  • 15 years
  • 20 years
  • 25 years
  • 30 years

The default option is 30 years.

A shorter mortgage term generally results in a higher monthly payment but can reduce the amount of interest paid over the life of the loan.

A longer term generally produces a lower required monthly payment but gives the lender more time to collect interest.

When evaluating a refinance, consider both the monthly payment and the long-term cost.

7. Enter Closing Costs

The calculator includes a closing-cost field with a default value of $5,000.

Closing costs can include various expenses associated with completing a mortgage transaction.

Examples may include:

  • Loan origination charges
  • Appraisal costs
  • Title-related expenses
  • Recording fees
  • Other lender or settlement charges

Actual costs vary significantly depending on the lender, location, loan type, property, and transaction.

The calculator assumes the closing costs are financed into the new loan when calculating the new loan amount.

What Does the Calculator Calculate?

After entering your information, click Calculate.

The tool provides four primary results.

New Loan Amount

The new loan amount is calculated as:

Current Mortgage Balance + Cash-Out Amount + Closing Costs

For example:

  • Current mortgage: $250,000
  • Cash out: $50,000
  • Closing costs: $5,000

The estimated new loan amount would be:

$305,000

This means the new mortgage would replace the existing $250,000 mortgage while also providing $50,000 in cash-out funds and financing $5,000 of closing costs.

New Monthly Payment

The calculator estimates the monthly principal-and-interest payment using the new loan amount, new interest rate, and selected loan term.

The calculation uses a standard mortgage amortization formula.

For a loan with a positive interest rate, the monthly payment is calculated based on:

  • Principal
  • Monthly interest rate
  • Number of monthly payments

The calculator does not separately add property taxes, homeowners insurance, HOA fees, or other housing expenses.

Therefore, the displayed payment should generally be viewed as an estimated principal-and-interest payment, rather than the complete monthly cost of owning the home.

Net Cash Received

Net cash is calculated as:

Cash-Out Amount − Closing Costs

For example:

  • Cash-out amount: $50,000
  • Closing costs: $5,000

Net cash received would be:

$45,000

This is an important distinction because requesting $50,000 in cash does not necessarily mean you will have $50,000 available after transaction costs.

The actual amount you receive at closing can depend on the final settlement statement and other transaction adjustments.

New Loan-to-Value Ratio

The calculator estimates your new LTV using:

New LTV = New Loan Amount ÷ Home Value × 100

For example:

  • Home value: $400,000
  • New loan: $305,000

The resulting LTV would be:

76.25%

The calculator displays this figure rounded to one decimal place.

Why Loan-to-Value Ratio Matters

Loan-to-value ratio is an important concept in mortgage lending.

A lower LTV generally means the borrower has more equity relative to the amount borrowed.

For example:

  • $200,000 loan on a $400,000 home = 50% LTV
  • $300,000 loan on a $400,000 home = 75% LTV
  • $320,000 loan on a $400,000 home = 80% LTV
  • $360,000 loan on a $400,000 home = 90% LTV

The higher the LTV, the less equity remains in the property relative to the mortgage balance.

Lenders can have specific LTV requirements depending on the mortgage product and transaction.

The calculator displays a warning when the calculated LTV exceeds 80%, indicating that the borrower may face additional requirements, possible mortgage insurance considerations, or loan-approval limitations depending on the loan program.

An 80% threshold should not be treated as a universal rule for every refinance because lender requirements vary.

Cash-Out Refinance Example

Consider a homeowner with these hypothetical numbers:

  • Current home value: $400,000
  • Current mortgage balance: $250,000
  • Current interest rate: 6.50%
  • New interest rate: 5.75%
  • Cash-out amount: $50,000
  • New loan term: 30 years
  • Closing costs: $5,000

Step 1: Calculate the New Loan Amount

The calculator adds:

$250,000 + $50,000 + $5,000

New loan amount = $305,000

Step 2: Calculate Net Cash

The requested cash-out amount is $50,000, but $5,000 is allocated to closing costs.

$50,000 − $5,000

Net cash = $45,000

Step 3: Calculate New LTV

$305,000 ÷ $400,000 × 100

New LTV = 76.25%

The calculator would display approximately 76.3%.

Step 4: Estimate the New Payment

The calculator then uses the $305,000 balance, 5.75% new interest rate, and 30-year term to estimate the monthly principal-and-interest payment.

This example demonstrates why looking at the cash received alone is not enough. The homeowner is also taking on a new $305,000 mortgage balance.

When Might a Cash-Out Refinance Make Sense?

A cash-out refinance may be considered for a variety of reasons.

Home Improvements

Homeowners sometimes use equity to pay for renovations, repairs, additions, or other improvements.

Projects that improve the property’s usefulness or condition may be considered when evaluating whether borrowing against home equity makes financial sense.

However, it is important to compare the expected benefit of the project with the cost of borrowing.

Debt Consolidation

Some homeowners consider using home equity to pay off higher-interest debt.

This can potentially reduce the interest rate on the debt being consolidated, but it also changes the nature of the debt.

Credit card debt is generally unsecured, while a mortgage is secured by the home. Using mortgage debt to consolidate other debts means your home is tied to the repayment obligation.

Major Expenses

Homeowners may also consider cash-out refinancing for major financial expenses.

However, because refinancing can involve substantial transaction costs and increases the mortgage balance, it is important to evaluate whether using home equity is appropriate.

Cash-Out Refinance vs. Home Equity Loan

A cash-out refinance is not the only way to access home equity.

A home equity loan generally allows you to borrow against your available equity without replacing your existing first mortgage.

A cash-out refinance, by contrast, replaces the existing mortgage with a new mortgage.

This creates an important consideration: if your existing mortgage has a very low interest rate, refinancing the entire balance into a higher-rate loan could potentially increase your borrowing costs even if you receive cash.

A homeowner should compare:

  • New mortgage rate
  • Existing mortgage rate
  • Closing costs
  • New loan balance
  • Monthly payment
  • Total interest
  • Amount of cash needed
  • Alternative financing options

Cash-Out Refinance vs. HELOC

A home equity line of credit (HELOC) is another way homeowners may access home equity.

Unlike a cash-out refinance, a HELOC is typically a separate credit line secured by the home.

The main difference is that refinancing replaces the existing mortgage, while a HELOC generally leaves the existing first mortgage in place.

A HELOC may be worth comparing if you want to preserve a favorable existing mortgage rate.

However, HELOC interest rates and repayment structures can differ from traditional mortgages, so the total cost and risks need to be considered carefully.

What Happens When You Increase Your Mortgage Balance?

Taking cash out means increasing the amount owed against your property.

Suppose you currently owe $200,000 and refinance into a $300,000 mortgage.

You have effectively increased your mortgage debt by $100,000 before considering other adjustments.

This can reduce your home equity.

For example, if the home is worth $400,000:

  • $200,000 mortgage = 50% LTV
  • $300,000 mortgage = 75% LTV

Although you still have substantial equity, you now have a larger mortgage obligation.

The calculator makes this effect easier to visualize through its New Loan Amount and New LTV results.

How Interest Rates Affect a Cash-Out Refinance

The new interest rate is one of the most important factors in determining your new payment.

Suppose you currently have a mortgage at 7% and qualify for a new mortgage at 6%.

The lower rate could help reduce the interest cost on the refinanced balance.

However, the comparison cannot be made by looking at interest rates alone.

If your current mortgage balance is $200,000 and your new refinance balance becomes $300,000, the new loan could still have a higher monthly payment despite the lower rate.

That is why it is important to evaluate the loan amount, interest rate, term, and closing costs together.

Why Closing Costs Matter

Closing costs can have a major effect on whether refinancing makes financial sense.

If you pay $5,000 in closing costs, that expense reduces the amount of cash you actually receive if the costs are deducted from your cash-out amount.

If the costs are instead financed into the mortgage, your loan balance increases.

For example:

Cash-out requested: $50,000
Closing costs: $5,000
Net cash: $45,000

But the calculator also adds the $5,000 closing costs to the new loan balance.

This means you are effectively financing those costs over the life of the new mortgage.

Understanding the Break-Even Point

One useful concept when considering refinancing is the break-even period.

The break-even period estimates how long it may take for the savings generated by refinancing to offset the upfront costs.

For example, suppose refinancing costs $6,000 and reduces your monthly payment by $300.

A simple break-even estimate would be:

$6,000 ÷ $300 = 20 months

After approximately 20 months, the payment savings would equal the initial costs, assuming all other factors remain unchanged.

However, cash-out refinancing can be more complicated because you are also increasing your loan balance and receiving cash.

The calculator provided here does not calculate a break-even period, so you should not assume that a lower monthly payment automatically means refinancing will save money.

Important Limitations of This Calculator

The Refinance Cash Out Mortgage Calculator provides useful estimates, but it does not model every component of a real mortgage transaction.

For example, it does not calculate:

  • Property taxes
  • Homeowners insurance
  • HOA dues
  • Mortgage insurance premiums
  • Prepayment penalties
  • Discount points
  • Escrow adjustments
  • Variable interest rates
  • Lender-specific fees
  • Credit-based pricing
  • Appraisal results
  • Actual loan eligibility
  • Future home-value changes

The calculator also uses the current mortgage rate only as an input for comparison; it does not calculate your current mortgage payment or compare your current payment against the new payment.

Therefore, the tool should be used as a preliminary planning resource rather than a replacement for a lender’s official loan estimate.

Tips for Using a Cash-Out Refinance Calculator

For more useful results, try several different scenarios.

Compare Different Loan Terms

Calculate the payment using 15-, 20-, 25-, and 30-year terms.

You may discover that a shorter term significantly changes your monthly payment while potentially reducing long-term interest costs.

Test Different Cash-Out Amounts

Instead of automatically borrowing the maximum amount available, compare smaller cash-out amounts.

For example, calculate:

  • $20,000 cash out
  • $30,000 cash out
  • $40,000 cash out
  • $50,000 cash out

This can show how additional borrowing affects the new mortgage.

Compare Interest Rates

Try several potential rates to see how much the payment changes.

Even a difference of 0.50 percentage points can affect the monthly payment when applied to a large mortgage balance.

Watch the LTV

Keep an eye on the New LTV result.

A larger cash-out amount increases the new loan balance and therefore increases LTV, assuming the home’s value remains unchanged.

Consider the Total Cost

Do not evaluate a refinance only by the monthly payment.

A lower monthly payment could result from extending the repayment period, which may increase the total amount of interest paid over time.

Frequently Asked Questions

1. What is a cash-out refinance?

A cash-out refinance replaces an existing mortgage with a larger mortgage and allows the homeowner to access some of the property’s equity as cash, subject to lender requirements.

2. How does the calculator determine the new loan amount?

The calculator adds the current mortgage balance, requested cash-out amount, and closing costs.

New Loan Amount = Current Mortgage + Cash Out + Closing Costs

3. What is loan-to-value ratio?

LTV compares the mortgage balance with the home’s value. It is calculated by dividing the loan amount by the property value and multiplying by 100.

4. What is considered a good LTV?

There is no single LTV that is universally “good.” Lower LTV generally means more equity, while lender requirements vary by loan type and borrower circumstances.

5. Why does the calculator warn me when LTV exceeds 80%?

The calculator displays a warning above 80% because higher LTV can affect mortgage eligibility, pricing, and potential mortgage insurance requirements depending on the loan program and lender.

6. Does the calculator include closing costs?

Yes. You can enter your estimated closing costs. The calculator adds those costs to the new loan amount and subtracts them from the cash-out amount when calculating net cash.

7. What is net cash received?

Net cash received is the requested cash-out amount minus the closing costs entered into the calculator.

8. Does cash-out refinancing increase my mortgage balance?

Yes. The cash-out amount increases the amount borrowed. If closing costs are financed, they increase the new loan balance as well.

9. Does a lower interest rate always make refinancing worthwhile?

No. Refinancing can involve closing costs, and a cash-out refinance may increase the loan balance. A lower rate alone does not guarantee that refinancing will save money.

10. Does a 30-year refinance have a lower payment than a 15-year refinance?

Generally, yes, assuming the loan amount and interest rate are the same. However, the longer term can result in more total interest over the life of the loan.

11. Can I use a cash-out refinance for debt consolidation?

Some homeowners use cash-out refinancing for debt consolidation, but whether it is financially appropriate depends on the interest rates, fees, repayment period, and risks involved.

12. Does the calculator determine whether I qualify for a refinance?

No. It only provides mathematical estimates. Lenders determine eligibility using their own underwriting requirements.

13. Does the calculator include taxes and insurance?

No. The displayed new monthly payment is based on the mortgage principal and interest calculation. Property taxes, homeowners insurance, HOA fees, and other costs are not included.

14. What happens if my home’s value decreases?

A lower home value can increase your LTV because the mortgage balance represents a larger percentage of the property’s value. This can affect your available equity and potentially your refinancing options.

15. Should I use this calculator before applying for a cash-out refinance?

Yes, it can be useful for estimating different scenarios before speaking with a lender. However, use the results as estimates and compare them with the lender’s official terms, fees, rate, and loan disclosures.

Final Thoughts

A Refinance Cash Out Mortgage Calculator can be a helpful starting point for homeowners considering whether to access their home equity through refinancing.

By entering your home value, current mortgage balance, current and new interest rates, desired cash-out amount, loan term, and closing costs, you can quickly estimate the potential new loan amount, monthly payment, net cash received, and loan-to-value ratio.

The most important thing is to look at the complete financial picture. Receiving cash from your home can be useful, but it also increases your mortgage debt and may increase the amount of interest you pay over time.

Before proceeding, compare the new mortgage with your existing loan and other potential financing options. Pay close attention to the interest rate, closing costs, repayment term, new loan balance, and LTV.

Finally, remember that calculator results are estimates. Your actual refinance terms will depend on the lender, your financial circumstances, property value, loan program, market conditions, and the final terms offered to you.
