What is a Loan Calculator?
A Loan Calculator estimates your monthly payment and total interest cost based on the loan amount, interest rate, and term you provide.
Our free Loan Calculator uses the standard reducing-balance method most lenders apply, helping you compare loan scenarios before you formally apply.
A loan payment calculation comes down to three inputs working together: the principal amount borrowed, the interest rate, and the loan term, with the standard reducing-balance method most lenders use charging interest only on whatever balance remains after each payment, rather than on the original full amount for the entire loan life. Understanding that distinction explains why the same interest rate can produce very different total costs depending on how long the loan runs.
Our Loan Calculator estimates your monthly payment based on the amount, rate, and term you enter, using this standard reducing-balance approach. A longer loan term lowers the monthly payment, which can look more affordable at a glance, but it also increases the total interest paid over the full life of the loan, sometimes substantially, even at an identical interest rate to a shorter-term alternative; comparing loans by total interest paid, not just the monthly figure, gives a genuinely clearer picture of the real cost difference.
It's worth being clear about what this calculator can and can't tell you. It calculates payments based on the numbers you provide, but it has no way to assess whether you'll actually qualify for a specific loan, since real approval depends on your credit history, income, existing debt, and the individual lender's own underwriting criteria, none of which a calculator can evaluate. Many loan calculators also let you model a hypothetical extra payment, showing how much interest and time you'd save by paying down principal faster than the minimum required schedule.
