Mortgage calculator
Get the real payment, not the teaser number. Taxes, insurance, HOA dues, PMI, and payoff speed stay visible so the loan does not look cheaper than it is.
Start with the likely payment, not the best-case pitch.
Advanced inputs Only open this if HOA, PMI, or payoff speed matters to the decision.
Principal, interest, taxes, insurance, HOA, and PMI together.
Sources & assumptions used in this calculator
This calculator is educational and estimates payment pressure using common mortgage math. It is not a loan estimate, approval, or lending disclosure.
- Principal and interest are estimated from loan amount, rate, and term.
- Taxes, insurance, HOA dues, PMI, and optional extra payments are shown because the monthly payment is rarely just the loan payment.
- Reference points include CFPB mortgage resources, HUD homebuying guidance, and Freddie Mac consumer mortgage guidance.
Use it for offer math and payment sanity checks, then confirm final numbers with a lender, insurance quote, tax record, and HOA documents.
Example scenario: teaser payment vs. real payment
A listing or loan conversation can make a house look affordable by focusing on principal and interest. The real monthly decision changes when property taxes, insurance, HOA dues, PMI, and maintenance reserves are added.
Practical read: if the all-in payment is hundreds higher than the teaser number, compare the real payment to take-home income before deciding the house is affordable.
Pressure-test this payment against the budget
Before you trust the monthly number, check whether it still works once your comfort range and refinance alternatives are in view.
Payment decision table
Do not stop at principal and interest.
A mortgage payment is only useful when it includes the costs that actually hit your checking account.
