Frequently Asked Questions
What is the difference between equal monthly payment and equal principal?
Equal monthly payment (annuity) means the same total payment every month — early payments are mostly interest, later ones mostly principal. Equal principal means you pay the same principal every month, so total payments start high and decrease.
Does this account for taxes or insurance?
No. This calculator focuses on principal and interest only. For full mortgage costs, add property tax, insurance, and HOA fees separately.
