House Down Payment Calculator
Work out the down payment you need for a home from the price and percentage.
The upfront cost of buying
A down payment is the portion of a home's price you pay upfront, with the rest borrowed as a mortgage. This works out the amount from the price and the percentage you plan to put down, so you know the deposit to save for one of the largest purchases you will make.
Enter the home price and down payment percentage to see the amount.
Why a bigger deposit helps
The size of the deposit has knock-on effects beyond the upfront cost. A larger down payment means borrowing less, so a smaller mortgage, lower monthly payments and less total interest. It can also unlock better interest rates and, crucially, avoid the extra cost of mortgage insurance that lenders often require when the deposit is below a certain threshold. That is why the common target of a substantial deposit is not arbitrary — it saves money in several ways at once. Against that, saving a huge deposit takes time and ties up cash, so the right balance depends on your situation. This calculates the figure; whether and how much to put down is a personal financial decision.
Common questions
Why does a larger down payment help?
It means a smaller mortgage, so lower payments and less total interest, and it can secure better rates and avoid mortgage insurance charged on small deposits.
Is there a target deposit percentage?
A substantial deposit often avoids extra insurance costs and gets better rates, but the right amount balances that against how long saving it takes. It is a personal decision.
