How a down payment works

A down payment is the part of a home price you pay up front, with the rest borrowed as a mortgage. This down payment calculator, a deposit calculator for a home purchase, turns a percentage into the cash amount, then shows the loan you would need and the loan-to-value ratio. It is the starting point for a down payment on a house. So a 20% down payment on a 300,000 home is 60,000 down and a 240,000 loan, at an 80% loan-to-value.

Loan-to-value explained

Loan-to-value, or LTV, is the loan as a percentage of the price, which is simply 100 minus your down payment percentage. A bigger down payment means a lower LTV, which lenders see as less risky and often reward with a better interest rate. The table shows several common down payment levels side by side so you can weigh the trade-off.

How much down payment do you need

Minimum down payments vary widely. Some loans and countries allow low single-digit percentages, while a larger down payment can unlock better terms. A well-known example is the idea that 20% down avoids extra mortgage insurance, but that specific rule is common in some markets and not others. Requirements depend on the lender, the loan type, and the country, so check what applies where you are.

An estimate, not financial advice

FAQ

How do I calculate a down payment?

Multiply the home price by the down payment percentage. The tool does this and also shows the resulting loan amount and loan-to-value.

How much down payment do I need?

It varies by lender, loan type, and country, from low single digits to 20% or more. A larger down payment lowers the loan and often the rate. Check your local requirements.

What is loan-to-value?

The loan as a percentage of the home price, which equals 100 minus your down payment percentage. A lower loan-to-value is seen as less risky by lenders.

Does 20% down really matter?

In some markets a 20% down payment avoids extra mortgage insurance and can improve the rate, but that rule is not universal. It depends on where you are and the loan.
