What Is Repayment?
Repayment is the process of paying back money you've borrowed through a series of periodic payments, each combining a principal portion (reducing the balance) and an interest portion (the lender's charge for the loan). Mortgages, auto loans, student loans, and personal loans all follow this same structure — only the balance, rate, and schedule differ.
Some loans quote their rate with one compounding frequency (say, quarterly) while payments are due on a different schedule (say, monthly). This calculator converts between the two using the standard effective-rate formula, so the payment or term it produces reflects the loan's true cost regardless of how the rate was originally quoted.
Remaining balance over time
Year-by-Year Repayment Schedule
| Year | Paid This Year | Interest Paid | Remaining Balance |
|---|---|---|---|
| 1 | $12,748 | $4,635 | $41,887 |
| 2 | $12,748 | $3,785 | $32,924 |
| 3 | $12,748 | $2,847 | $23,022 |
| 4 | $12,748 | $1,810 | $12,084 |
| 5 | $12,748 | $664 | $0 |
How Mismatched Frequencies Are Handled
The quoted annual rate is first converted to an effective annual rate using the compounding frequency, then converted again into a periodic rate matching the payment frequency. This two-step conversion is the standard method lenders use whenever a loan compounds on one schedule but is paid on another.
Fixed Term vs. Fixed Payment
Choosing a fixed term solves for the payment needed to clear the balance by a set date — exactly how a standard installment loan is structured. Choosing a fixed payment instead solves for how long it takes to pay off the balance at an amount you specify, which is useful for testing "what if I paid $X per period" scenarios.
Biweekly and Weekly Acceleration
Switching from monthly to biweekly payments (26 half-sized payments per year instead of 12 full payments) effectively adds one extra monthly payment annually, which can meaningfully shorten a loan's term and cut total interest without increasing the payment amount much.

Additional Example — Quarterly Compounding, Monthly Payments
A $12,000 loan at 9% compounded quarterly but paid monthly over 4 years works out to a monthly payment of roughly $299 and about $2,340 in total interest — slightly more than if the same 9% rate compounded monthly instead, because quarterly compounding produces a marginally higher effective annual rate.
About These Parameters
- Loan Balance & Interest Rate
- The amount currently owed and the nominal annual rate quoted by the lender, before any compounding or payment-frequency adjustment.
- Compounding vs. Payment Frequency
- Compounding is how often the lender applies interest to your balance; payment frequency is how often you actually send a payment. Most consumer loans compound monthly and are paid monthly, but this calculator supports any combination.
- Solve For
- Pick "fixed term" if you know how long you want to take to repay and need the payment amount, or "fixed payment" if you know what you can afford per period and want to see how long repayment will take.
Frequently Asked Questions
Why does compounding frequency matter if I pay monthly?
Even at the same nominal rate, quarterly or daily compounding produces a slightly higher effective annual rate than monthly compounding, which raises the periodic payment or extends the payoff term.
What does "never pays off" mean?
If your chosen fixed payment doesn't even cover the interest accruing each period, the balance grows instead of shrinking — the calculator flags this rather than showing a misleadingly long payoff term.
Can I use this for a mortgage?
Yes, though our dedicated Mortgage Calculator adds property-specific extras like taxes, insurance, and PMI on top of the same core repayment math.
