How is down payment amount calculated?

Down payment = home price × down payment percentage, giving the upfront cash needed before financing the remaining balance.

What down payment percentage is typical?

Conventional loans often suggest 20% to avoid private mortgage insurance (PMI), though many loan programs allow much lower down payments, sometimes 3-5%.

What happens if I put down less than 20%?

Most conventional lenders require PMI (private mortgage insurance) until you build enough equity, which adds to your monthly payment until removed.

What Is a Down Payment Calculator?

A down payment calculator tells you exactly how much cash you need upfront when buying a home, car, or any large purchase, and how much you'll need to finance with a loan. Lenders typically require anywhere from 3% to 20% of the purchase price as a down payment, and putting down less than 20% on a home usually means paying for Private Mortgage Insurance (PMI).

The purchase price splits into your down payment and the remaining loan amount.

Formula

Down Payment ($) = Purchase Price × (Down Payment % ÷ 100)
Loan Amount = Purchase Price − Down Payment

How to Use This Calculator

Enter the total purchase price of the home, car, or item.
Enter the down payment percentage you plan to put down.
Click "Calculate Down Payment" to see the exact cash needed and the resulting loan amount.
If the percentage is below 20% on a home purchase, the calculator flags that PMI is typically required.

Worked Example

Example: A home costs $350,000 and you plan to put down 20%. Down Payment = $350,000 × 0.20 = $70,000. Loan Amount = $350,000 − $70,000 = $280,000.
