Conventional Loan Down Payment Calculator
Buying a home is one of the biggest financial decisions you’ll make. Knowing exactly how much you need for a down payment, what your monthly mortgage payments will be, and whether you’ll need Private Mortgage Insurance (PMI) is crucial before signing on the dotted line.
Our Conventional Loan Down Payment Calculator helps you plan every step of your mortgage. Enter your home price, down payment percentage, loan term, and interest rate to see a detailed breakdown of your loan costs.
How It Works
The calculator takes the following inputs:
- Home Purchase Price – Total cost of the property you want to buy.
- Down Payment Percentage – The percentage of the home price you plan to pay upfront.
- Loan Term – Duration of your mortgage in years (10, 15, 20, or 30 years).
- Annual Interest Rate – Your mortgage’s yearly interest rate.
Based on these inputs, it calculates:
- Down Payment Amount – How much money you need upfront.
- Loan Amount (Principal) – The mortgage balance after your down payment.
- Monthly Mortgage Payment – Your monthly payment for principal and interest.
- Total Amount Paid – Total money spent over the loan term including down payment.
- Total Interest Paid – How much interest you’ll pay over the life of the loan.
- PMI Requirement – Whether Private Mortgage Insurance is needed (if down payment < 20%).
Example Calculation
Suppose you’re buying a $350,000 home with a 15% down payment, a 30-year term, and 6.5% annual interest.
- Down Payment: $52,500
- Loan Amount: $297,500
- Monthly Payment: ~$1,878
- Total Paid: ~$676,280
- Total Interest Paid: ~$378,780
- PMI: Yes (because down payment < 20%)
This gives you a clear picture of your financial commitment before applying for the mortgage.

Tips for Using the Calculator
