About Mortgage Calculator

VestCalc's Mortgage Calculator is a free online loan analysis tool that helps borrowers understand the true cost of debt, compare financing options, and make informed decisions about mortgages, personal loans, auto loans, and other credit products. Getting a loan without fully understanding the payment schedule, total interest cost, and amortisation structure can lead to significant financial surprises our calculator makes all of these transparent before you commit.

The Mortgage Calculator calculates monthly payment amounts, total interest paid over the life of the loan, the complete amortisation schedule showing how each payment splits between principal and interest, and how extra payments or different loan terms affect your total cost. These insights help you negotiate better terms, decide between loan options, and understand the financial impact of your borrowing decisions.

Key inputs include loan amount, interest rate (APR), loan term, and any additional payment amounts. The tool instantly recalculates when you adjust any variable, making it easy to run side-by-side comparisons of different scenarios such as a 15-year versus 30-year mortgage, or the savings from making bi-weekly instead of monthly payments.

VestCalc is dedicated to providing free, professional-quality financial tools to help individuals make better-informed borrowing decisions. This Mortgage Calculator requires no account, stores no personal data, and is available 24/7 on any device. Use it whenever you are evaluating a loan or refinancing option.

Can I compare different loan scenarios with Mortgage Calculator?

Is my financial data stored when I use Mortgage Calculator?

Mortgage payment method and cost boundaries

The calculator amortizes principal and interest from the loan amount, rate, and term entered by the user. The full housing payment can also include property taxes, homeowners insurance, mortgage insurance, association dues, and other costs that are not part of the loan formula.

Compare the output with a written Loan Estimate using the same loan type, term, amount, and rate-lock status. Check whether points, lender credits, and closing costs change the comparison. Adjustable rates, prepayments, late charges, escrow changes, and refinancing are outside a basic fixed-payment schedule.
