Down Payment Calculator

How the savings time is calculated

The tool multiplies the property price by your chosen down payment percentage to find the cash you need, then divides that amount by your monthly savings while factoring in the annual return you expect, which speeds up the build-up through compounding.

For example, a 250,000 home with a 15 percent down payment means 37,500 in cash. Saving 500 a month at a modest return puts the savings horizon at roughly six years.

What you enter and what you get

You enter the property price, your target down payment percentage, the amount you save each month, and an estimated annual return on your savings.

In return you see the required down payment in dollars, the savings time in years and months, and the loan amount left to apply for from the bank.

Who it is for

The calculator helps first-time buyers gauge a realistic timeline and existing owners planning to trade up understand the balance between cash and loan. You can test how raising your monthly savings shortens the wait.

Good to know

US lenders usually ask for a 10–20 percent down payment on a conventional mortgage, though some programs allow less. For buyers under 45, an ASP account offers interest support and a government guarantee, which can reduce the cash you need to save yourself.

Remember that transfer tax of roughly 1.5–3 percent and moving costs come on top of the down payment, so keep a small buffer beyond the calculated figures.
