The Down Payment Calculator tells you the cash required for a target home at your chosen percent, the gap from what you have saved, and exactly how long it will take to get there — with a savings plan that shows how boosting monthly contributions pulls the date earlier.

Frequently Asked Questions
What does it compute?
The down payment required for a target price and desired percent, the gap from current savings, and months to close that gap.
Why a savings rate?
It turns the shortfall into a timeline so you know when you can buy.
Should I count interest?
Optionally, savings earn interest, shortening the timeline slightly.
What about closing costs?
This focuses on the down payment; add closing costs to total cash needed.
How does saving more help?
A higher monthly savings obviously shortens the wait; the tool shows the new date.
Is 20% required?
No — many loans allow less, but 20% avoids PMI. The target percent is yours to set.
Is my data stored?
No. All calculation runs in your browser; nothing is uploaded, saved or logged.
