Frequently Asked Questions

How is the monthly mortgage payment calculated?

The formula is M = P[r(1+r)^n]/[(1+r)^n-1], where P is the loan amount, r is the monthly interest rate, and n is the total number of payments.

Should I make a 20% down payment?

A 20% down payment avoids private mortgage insurance (PMI) and lowers your monthly payment, but many loans allow lower down payments.

Does this include taxes and insurance?

This calculator estimates principal and interest only. Property taxes, insurance, and PMI are additional costs.
