Repayment Calculator

Repayment, Solved Both Ways

Repayment is the act of returning borrowed money in periodic installments of principal and interest — on a mortgage, an auto loan, a student loan, or a card balance. Lenders quote a rate and a compounding convention; borrowers control a term or an installment. Fix one and the other is determined, which is why this calculator has the same two modes as the loans themselves: a fixed term (what must I pay to be done in five years?) and a fixed installment (how long does $200 a time take?). Failing to repay as agreed is what damages credit ratings and, at the end of the road, forces bankruptcy — so the honest number matters more than the comfortable one.

Compounding vs. Payment Frequency

Two different clocks run inside every loan. The compounding clock says how often interest is added to the balance — annually, monthly, daily, or continuously — and converts the quoted annual rate into the rate each period really carries. The payment clock says how often you pay. When they differ, the calculator converts properly: the per-payment rate is the one that grows money at the same speed as the compounding does. This is why a 10% rate can produce different installments for the same term depending on the compounding chosen, and why comparing loan offers without matching compounding conventions misleads.

Repaying Faster

Three strategies recur because they work. Pay extra: any amount above the installment goes straight to principal (prepayment penalties aside), shrinking every future interest charge. Pay biweekly: half-installments every two weeks add up to thirteen full payments a year instead of twelve, and the balance — hence the interest — falls sooner; try the biweekly payback above and watch the totals. Refinance: replace the loan with a cheaper or shorter one when the fee is smaller than the interest saved, which the Debt Consolidation and Refinance calculators on this site judge directly. Behind all three sits the same warning: money sent to a loan cannot be un-sent, so an emergency fund comes first, and a low-rate loan may honestly be worth less than the investment the same cash could make.

Frequently Asked Questions

Why does compounding change my payment?

Because it changes what the rate means: 10% compounded monthly is a 10.47% effective year; compounded annually it is exactly 10%. Same sticker, different engine — the annual-compounding payment is the smaller one, $210.36 vs. $212.47 at the defaults.

Why "4.9 months"? Do I pay a partial month?

The fractional figure is the exact mathematical term. In practice you make one more payment than the whole periods — 65 here — and the last is smaller than usual. The totals shown always come from the real schedule.

Do biweekly payments actually save anything?

Yes: 26 half-payments equal 13 monthly payments a year, and earlier payments mean less interest accrues. Confirm your lender applies them without fees.
