Estimate your monthly payment including principal and interest, property taxes, homeowners insurance and PMI. U.S. dollars by default.
Mortgages look intimidating because a lot of moving parts get bundled into a single number. This calculator splits them back out. You’ll see the core payment (principal & interest) plus the extras most people actually pay each month: property taxes, homeowners insurance, PMI (when the down payment is under 20%), and any HOA dues. The amortization table shows how much of the payment goes to interest vs. principal and how the balance falls over time. Everything runs locally in your browser and you can export the full schedule to CSV.
If you’re comparing multiple loan types or want to sanity-check affordability, pair this page with the Loan Calculator for non-mortgage debt and the Debt-to-Income Ratio tool to see how a payment fits in your monthly budget. When tax season rolls around, the Federal Income Tax Calculator can provide a ballpark for withholding and refunds.

Want to stress-test debt load? Use the Debt-to-Income tool to see if your projected payment is within typical lender thresholds.
Principal & Interest (P&I): This is the amortized payment based on your interest rate, loan amount, and term. Early in the loan, more of P&I goes to interest; later, principal dominates.
Property tax & Insurance: These are estimates, but they matter for affordability. Lenders often collect them monthly in an escrow account, so your “real” payment includes them even though they’re not part of the note.
PMI: If the down payment is under 20%, PMI is added monthly until your balance falls to 80% loan-to-value (LTV). This calculator drops PMI from the schedule at that point and keeps building the amortization without it.
Balance trajectory: The amortization schedule shows how balance shrinks. If you’re comparing offers, look at total interest paid in the exported CSV (sum of the Interest column). A lower rate or shorter term typically reduces lifetime interest.
Tip: considering a refi or an extra principal plan? Use the CSV in a spreadsheet to model extra payments. Or jump to the Loan Calculator for a simpler principal/interest what-if.
PMI usually ends when your loan-to-value reaches 80%. We track LTV month by month and remove PMI from the schedule once your balance crosses that threshold.
Principal and interest are exact given the APR, loan amount, and term. Taxes vary by location and assessment; insurance depends on policy details and coverage. Treat those as planning numbers.
Yes—download the CSV, add an “extra principal” column in your spreadsheet, and recalc the remaining balance each month. You’ll see the payoff date pull forward and interest drop.
Not on this page. A biweekly plan is effectively one extra monthly payment per year. You can approximate it by adding an extra principal line in the CSV.
