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.

  1. Enter home price ($).
  2. Enter down payment (%).
  3. Click Calculate to see your results.

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.

Frequently asked questions

Yes, with no signup and no limit on how many calculations you run.
Conventional mortgage lenders typically require private mortgage insurance (PMI) on down payments below 20%, so hitting that threshold avoids the added monthly cost.
Yes — many loan programs allow down payments as low as 3-5%, though a smaller down payment usually means PMI and a larger loan amount.
No — closing costs are a separate expense, typically 2-5% of the loan amount, paid on top of the down payment.
