Loan Calculator

Know what you owe, and what it really costs.

Work out repayments and interest in seconds — then keep track of the loans you actually hold: the payments you have made, the rate changes along the way, and what paying a little extra would save you.

Principal Interest

Six repayment methods

Level payment, level principal, interest-only, interest-only-then-amortizing, and step-up — compared side by side on the same terms.

Your real loans

Tick off each payment as it goes out, correct the amount when the lender takes something different, and watch the balance follow.

Variable rates

Record every rate change. Completed payments stay as they were; only what is still ahead gets recalculated.

Paying extra

See what a lump sum saves, net of any early repayment fee — and whether to shorten the loan or shrink the payment.

Everything at once

Several loans, one dashboard: total balance, weighted average rate, and what is due this month.

Stays on your phone

No account, no sign-up, no bank connection. Your loan data never leaves the device.
