Mortgage Simulator is an educational planning tool. It estimates a fixed-rate amortized loan, escrow-like monthly costs, PMI, closing costs, payoff timing, and an amortization schedule, but actual lender quotes, tax bills, insurance, HOA dues, mortgage insurance, fees, and regulations can differ.
Mortgage Simulator turns purchase price, down payment, loan amount, rate, term, taxes, insurance, and HOA into a practical monthly and lifetime cost view.
Mortgage Simulator lets you enter the home price, down payment percentage, and editable loan amount so you can test how cash upfront changes the borrowed balance.
Mortgage Simulator compares 15 year, 20 year, and 30 year loans so you can see the tradeoff between lower monthly payment and higher total interest cost.
Use this Mortgage Simulator guide to compare a loan scenario before you talk with a lender or change your offer assumptions.

Answers about Mortgage Simulator formulas, principal and interest, taxes, insurance, HOA fees, and 15/20/30 year comparisons.
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.
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.
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.
No. Mortgage Simulator is for planning. It does not include every closing cost, mortgage insurance, escrow adjustment, lender fee, local rule, or qualification requirement.
