Frequently Asked Questions

How is a monthly mortgage payment calculated?

Monthly mortgage payments are calculated using the standard amortization formula based on loan amount, interest rate, and loan term. The tool breaks down each payment into principal and interest portions so you can see how the balance decreases over time.

What is included in a mortgage payment?

A basic mortgage payment covers principal and interest. In practice, lenders often bundle property taxes, homeowner insurance, and PMI into a single monthly payment (called PITI). This calculator focuses on principal and interest — use ToolPeg's home affordability calculator for a fuller estimate.

How does a longer mortgage term affect total cost?

A longer term (e.g., 30 years vs. 15 years) lowers your monthly payment but significantly increases the total interest paid over the life of the loan. Try both tenures in this calculator to see the tradeoff.

Should I make extra payments on my mortgage?

Extra payments toward principal can reduce total interest and shorten your loan term substantially. Even small additional monthly payments can save thousands over the life of the mortgage. Adjust the inputs to model different prepayment scenarios.
