How it works

Estimates your full monthly housing cost. Principal and interest come from the standard amortising formula; taxes, insurance and HOA are added on top, and PMI appears automatically when the down payment is under 20%.

The formula

P&I = P x r / (1 - (1 + r)^-n), plus (annual tax + insurance)/12 + HOA + PMI.
