Down Payment Savings Calculator

About this calculator

Saving for a down payment is a straightforward gap-closing exercise: subtract what you already have saved from your target down payment amount, then divide the remainder by how much you can set aside each month. The result is the number of months until you hit your goal, assuming the monthly contribution stays constant and the savings themselves earn little or no meaningful interest over the period.

This planning figure matters because down payment size directly affects a mortgage — a larger down payment can avoid private mortgage insurance, unlock better interest rates, and lower the monthly payment for the life of the loan, so many buyers deliberately target 20% of the home price rather than the legal minimum. This calculator takes your target down payment, current savings, and monthly saving amount to show exactly how many months of saving stand between you and being ready to buy.
