How to use this tool
  • Home price minus Down payment = principal borrowed.
  • Payment schedule chooses how often you pay; extra is added each period.
  • Extra payments reduce principal faster → less interest and earlier payoff.

Payment formula
Payment = P × ( r × (1+r)^n ) / ( (1+r)^n − 1 )
P = price − down payment; r = APR ÷ payments per year; n = years × payments per year
