How this down payment calculator works
This tool converts your down payment percentage into a dollar amount, then estimates resulting loan size and monthly principal-and-interest payment based on interest rate and loan term.
- Down payment amount = home price × down payment percent
- Loan amount = home price minus down payment
- Monthly payment estimate includes principal and interest only

Down payment calculator FAQ
Is 20% down required?
Not always. Many programs allow lower down payments, but 20% often helps avoid PMI on conventional loans.
Does this include taxes, insurance, or HOA?
No. This monthly estimate focuses on principal and interest. Add other housing costs separately.
What happens if I increase down payment?
A larger down payment reduces loan amount, which usually lowers monthly payment and total interest.
