Estimate your monthly payment and total interest for any loan.
The Loan Calculator tool estimates monthly payments and total interest for a loan based on the amount, interest rate, and term. Calculations run in your browser, so your figures stay private.
Compare loans, plan a mortgage, or budget for a car finance deal by seeing exactly how much each option costs per month and over the full term.
Understanding the true cost of a loan before signing is one of the most valuable financial habits you can build. The monthly payment and total interest figures reveal whether a mortgage, car finance, or personal loan fits your budget, and how much extra you pay over the term compared with the amount you borrow. This tool shows both numbers instantly so you can compare offers side by side.
Adjust the loan amount, interest rate, and term to see how each one changes the monthly payment and total interest. A longer term lowers the monthly payment but raises the total interest, while a shorter term does the opposite. Watching these trade-offs update in real time helps you pick the term that balances affordability against total cost.
Loan calculation runs entirely in your browser using the standard amortisation formula. When you enter the loan amount, annual interest rate, and term, the tool converts the annual rate to a monthly rate, applies the amortisation formula that converts those three values into a fixed monthly payment, and multiplies by the number of payments to derive the total amount paid and the total interest.
Your financial figures never leave your device — there is no upload, no server-side processing, and no copy retained after you close the tab. The calculation is instant because it operates on the values in memory. The estimate covers principal and interest only; add any fees or insurance separately to see the full monthly cost.
The amortisation formula assumes a fixed interest rate and equal monthly payments, which matches most standard personal loans and mortgages. For variable-rate loans, the estimate is accurate only for the initial fixed period.
