Down Payment Calculator

About this calculator

This calculator takes a purchase price and a chosen down payment percentage and splits it into two figures: the actual cash down payment amount and the remaining balance that would need to be financed through a loan. It's a simple multiplication, but seeing both numbers side by side next to a real price makes an abstract percentage concrete before you commit to it.

It's used mainly by home and car buyers comparing how different down payment percentages — say 10% versus 20% — change both the upfront cash needed and the size of the loan (and therefore the monthly payment) they'll be taking on. Lenders commonly treat 20% as a threshold on mortgages, below which extra costs like private mortgage insurance often kick in, so buyers frequently use a calculator like this to see exactly what hitting or missing that threshold means in real currency.
