The formulas
- Loan = price x (1 - down payment %)
- P&I = loan x r / (1 - (1 + r)^-n), r = rate / 12, n = years x 12
- Total = P&I + tax/12 + insurance/12 + mortgage insurance/12 + HOA
How it works
A mortgage bill has more than principal and interest. Escrow collects property tax and homeowners insurance each month, and loans above 80 percent loan-to-value carry private mortgage insurance in this tool. HOA dues are paid separately but belong in what you can afford.
The tool charges mortgage insurance only when the loan is above 80 percent of price. Rates vary by lender, credit score and state; use your Loan Estimate. See the PMI cancellation calculator for when the insurance can end.

Common questions
Is the tax rate based on price?
Local assessors may use a different assessed value. Use the rate from your tax bill when you have it.
Do taxes change the payment?
Yes. Escrow resets yearly as tax and insurance change.
Is this an APR?
No. It does not include points or closing costs.
