What this site does
The main calculator estimates principal, interest, taxes, insurance, HOA dues, and PMI so you can see a more realistic monthly payment than a simple principal-and-interest-only tool.
We also publish supporting guides around refinance math, PITI, PMI, state-level mortgage estimates, and common comparison questions people ask while shopping for a home loan.
How the calculator works
- Principal and interest are calculated from a standard fixed-rate amortizing loan formula.
- Property tax, insurance, HOA, and PMI are added on top to estimate a fuller monthly payment.
- When PMI is left blank and the down payment is under 20%, the site uses a rough industry-average estimate for planning purposes.
These numbers are meant for education and budgeting. Final loan terms depend on lender underwriting, credit, reserves, down payment, property type, taxes, insurance, and closing costs.
Editorial and disclosure notes
QuickMortgageMath is not a bank, broker, credit union, or lender. We do not issue mortgages and we do not guarantee approvals or rates.
Some outbound links may eventually be partner or affiliate links. If that happens, the cost to the user does not increase. We try to keep the calculator itself free, fast, and usable without a login.
