The monthly payment is calculated using the standard amortization formula: M = P[r(1+r)^n]/[(1+r)^n-1], where P is the principal, r is the monthly interest rate, and n is the number of payments.
This calculator shows the principal and interest portion of your payment. Property taxes, homeowner's insurance, and PMI (if applicable) would be additional costs.
A 20% down payment avoids private mortgage insurance (PMI), but many loans accept 3-10% down. Use our calculator to see how different down payments affect your monthly payment and total interest.
