Which loan should I pick — lower payment or lower total cost?

A lower monthly payment can cost more if the term is longer, because you pay interest for longer. This tool ranks loans by total cost (interest plus fees) so you see the genuinely cheaper option, then you can weigh affordability separately.

How accurate is the comparison?

Each loan uses the standard amortising-payment formula M = P × r(1+r)ⁿ / ((1+r)ⁿ − 1). Total interest is the sum of payments minus the principal, and total cost adds the upfront fees. Figures assume a fixed rate for the whole term.

Is my loan data sent anywhere?

No. The calculator is privacy-first — both loans are computed entirely in your browser and nothing is transmitted or stored on a server.

Loan Comparison Calculator

Loan comparison calculator

Two loan offers are rarely easy to compare: a lower rate might come with a longer term or upfront fees that wipe out the saving. This calculator puts Loan A and Loan B side by side — comparing monthly payment, total interest, fees and total cost — and tells you which is cheaper overall.

Each loan is amortised with the standard payment formula, and the winner is the one with the lowest total cost of credit. It is privacy-first: nothing leaves your browser.
