How this calculator works
Monthly principal and interest uses the standard fixed-rate formula. M = P · r(1+r)^n / ((1+r)^n − 1) where P is price minus down payment, r is the monthly rate, and n is the number of months. Extra principal is applied after the scheduled payment and shortens the loan. PMI is estimated only while the modeled down payment is under 20%.
This is a planning estimate, not a lender quote. Actual payments vary with points, prepaid interest, escrow cushions, mortgage insurance rules, and rounding. Not financial advice.
