A down payment is the upfront cash a buyer puts toward a home purchase — everything else is financed through the mortgage.
This calculator finds the down payment amount and the resulting loan amount from a home price and a down payment percentage.
How it works
Enter the home price and the down payment percentage you're planning to put down. The calculator multiplies the two to find the down payment amount, subtracts it from the home price to find the loan amount, and flags whether private mortgage insurance (PMI) is typically required.
- Enter home price ($).
- Enter down payment (%).

Examples
A 20% down payment
On a $400,000 home, a 20% down payment is $80,000, leaving a $320,000 loan — and no PMI requirement.
Who should use it
- Planning how much to save before buying a home.
- Comparing loan amounts across different down payment scenarios.
Industry applications
- Home buying and mortgage planning
- Real estate and mortgage lending
Advantages
- Instantly shows both the down payment amount and the resulting loan amount.
- Flags whether PMI is typically required based on the 20% threshold.
Limitations
- Doesn't calculate the actual PMI cost — only whether it's typically required.
Common mistakes to avoid
- Budgeting only for the down payment and forgetting closing costs, which are a separate, additional expense.
- Assuming 20% down is required — many loan programs allow significantly less.
Best practices
- Compare the monthly payment difference between a 20% down payment (no PMI) and a smaller down payment (with PMI) before deciding how much to put down.
Tips
- A larger down payment reduces both your loan amount and your monthly payment — run this calculator at a few different percentages to see the tradeoff.
