What Is a Mortgage Deposit?
A mortgage deposit is the upfront amount you pay toward a property’s purchase price. The remaining amount is borrowed from a lender.
For example:
- Property price: $400,000
- 20% deposit: $80,000
- Mortgage loan: $320,000
The larger your deposit, the smaller your loan—and often the better your mortgage terms.
Why Your Deposit Matters
Your deposit directly impacts:
- Your Loan-to-Value ratio (LTV)
- Your interest rate
- Monthly repayments
- Mortgage approval chances
- Private mortgage insurance (PMI) requirements
Most lenders prefer at least a 20% deposit because it reduces lending risk.

Example Calculations
Example 1: 20% Deposit
- Property Price: $400,000
- Deposit: 20%
- Additional Costs: $5,000
Results:
- Deposit = $80,000
- Mortgage = $320,000
- Total Upfront = $85,000
- LTV = 80%
Example 2: 10% Deposit
- Property Price: $300,000
- Deposit: 10%
- Additional Costs: $7,000
Results:
- Deposit = $30,000
- Mortgage = $270,000
- Total Upfront = $37,000
- LTV = 90%
A higher LTV typically means higher interest rates and possible insurance requirements.
What Is Loan-to-Value (LTV) Ratio?
The Loan-to-Value ratio measures how much of the property’s value you are borrowing.
For example:
- 80% LTV = You’re borrowing 80% of the property price.
- 90% LTV = Higher lender risk.
Lower LTV = Lower risk = Often better interest rates.
How Much Deposit Do You Need?
Typical mortgage deposit requirements:
- 5% minimum (high LTV loans)
- 10% common for many buyers
- 20% ideal to avoid extra insurance
- 25%+ for investment properties
The exact requirement depends on your lender and financial situation.
Additional Costs to Consider
Many buyers forget about upfront costs beyond the deposit. These may include:
- Loan origination fees
- Appraisal fees
- Legal fees
- Property taxes
- Insurance
- Moving expenses
That’s why this calculator includes an “Additional Costs” field—to give you a realistic total upfront amount.
