Mortgage Simulator FAQ

Answers about Mortgage Simulator formulas, principal and interest, taxes, insurance, HOA fees, and 15/20/30 year comparisons.

How does Mortgage Simulator calculate monthly principal and interest?

Mortgage Simulator uses the standard fixed-rate amortization formula with the loan amount, monthly interest rate, and number of monthly payments. If the rate is zero, it divides the loan amount evenly across the term.

Does Mortgage Simulator include taxes, insurance, and HOA fees?

Yes. Mortgage Simulator adds annual property tax divided by 12, annual insurance divided by 12, and monthly HOA fees to the principal and interest estimate.

Why does Mortgage Simulator compare 15, 20, and 30 year loans?

Those terms show the common tradeoff: shorter loans usually have higher monthly payments but lower total interest, while longer loans usually lower the monthly payment but increase total interest.

Is Mortgage Simulator a lender quote?

No. Mortgage Simulator is for planning. It does not include every closing cost, mortgage insurance, escrow adjustment, lender fee, local rule, or qualification requirement.

Can I share a Mortgage Simulator result?

Yes. Use the copy result link button to create a parameterized Mortgage Simulator URL with the entered scenario. Normal edits do not change the clean page URL.

Calculate your Mortgage Simulator result

Open Mortgage Simulator, enter home price, down payment, loan amount, interest rate, term, property tax, insurance, and HOA fees.

Then compare 15, 20, and 30 year scenarios to see monthly payment, total repayment, and total interest cost.
