What Is a Down Payment on a House?
A down payment is the upfront amount you pay when purchasing a home. It is typically expressed as a percentage of the home’s total price.
For example:
- 10% down payment on a $300,000 house = $30,000
- 20% down payment on a $300,000 house = $60,000
The remaining amount becomes your mortgage loan, which you repay over time with interest.
Understanding your down payment is crucial because it directly affects:
- Your loan size
- Monthly mortgage payments
- Interest costs over time
- Private mortgage insurance (PMI) requirements
That’s where this calculator becomes extremely useful.

Example Calculation
Let’s walk through a real-world example.
Scenario:
- Home Price: $400,000
- Down Payment: 20%
- Interest Rate: 6%
- Loan Term: 30 years
Step 1: Down Payment Calculation
20% of $400,000 = $80,000
Step 2: Loan Amount
$400,000 − $80,000 = $320,000
Step 3: Monthly Payment Estimate
With 6% interest over 30 years, your estimated monthly payment would be approximately $1,918.
This gives you a realistic idea of what to expect before speaking with a lender.
