Calculation breakdown
Method, assumptions and worked example
Your housing estimate adds principal and interest to annual property tax ÷ 12, annual insurance ÷ 12, monthly HOA and monthly mortgage insurance. Extra principal appears separately so you can see both the scheduled payment and planned cash outlay.
Worked example
For a 300,000 home with 60,000 down, a 240,000 mortgage at 6% over 360 months has principal and interest of 1,438.92. Add 300 monthly property tax and 100 insurance: the estimated total is 1,838.92 before HOA or mortgage insurance.
What changes the estimate?
The interest rate applies monthly to the outstanding loan. Extra principal shortens repayment; tax, insurance and HOA remain housing costs even after payoff. The amortization table contains loan payments only. Mortgage insurance stays at your entered amount; cancellation rules are not modeled.
Use actual property-specific quotes. This estimate excludes closing costs, repairs, utilities, rate resets and tax deductions. Escrow collection and the timing of your first payment can differ from a simple monthly model.
Frequently asked questions
Does the table include property taxes?
No. The repayment table tracks the loan only. The headline monthly estimate also includes your entered housing charges.
Does mortgage insurance stop automatically?
No. The monthly input is kept constant; request cancellation details from your lender.
