This repayment calculator has one job: turn the fields below into a number you can audit. No market feed, no credit pull, no account. On the default case (balance of $15,000.00, interest rate of 12.00%, repayment term of 5 years) the tool shows $333.67.
Keep units consistent. A 6 that should have been 0.06, or months typed as years, will wreck the story. When you need a sibling model, the Debt Repayment Calculator stays on CalculatorWeb so the assumptions can match. Official language lives on CFPB consumer tools.
Inputs on this repayment calculator
Each label is a variable in the model. If a unit is already shown as $ or %, do not convert it again.
- Balance — dollars. Sample $15,000.00.
- Interest Rate — annual percent unless the label says otherwise. Sample 12.00%. Type 6 for 6%, not 0.06.
- Repayment Term — years, not months. Sample 5 years.
Calculate refreshes the cards. Reset restores the sample. When you compare two offers, change only the field that actually differs.
Worked example
Using balance of $15,000.00, interest rate of 12.00%, repayment term of 5 years, the engine prints $333.67 as “Repayment Amount”.
- Balance: $15,000.00
- Monthly Repayment: $333.67
- Total Interest: $5,020.00
- Total Repaid: $20,020.00
If you retype those defaults and get a different headline, reload the page before you invent a more exotic explanation.
The formula
The model uses M = P × r(1+r)^n ÷ ((1+r)^n − 1). That is a standard classroom or practitioner identity for this kind of loans question. It does not pull live quotes and it does not score your credit.
Where this estimate goes wrong
Months typed as years (or the reverse) will wreck the payment. Read the unit on the label twice.

Questions people ask about this repayment calculator
What does this repayment calculator calculate?
It applies M = P × r(1+r)^n ÷ ((1+r)^n − 1) to the fields on this page. The large number is the headline; the four cards split it so you can check the pieces.
Is the rate an APR?
Not automatically. APR includes certain fees. If this page has a fee field, use it. If not, compare with an APR calculator.
Is the Repayment calculator free?
Yes. There is no signup wall on the tool. Use it whenever the question changes.
Can I treat $333.67 as advice?
No. It is an educational estimate from the sample or from numbers you typed. A licensed professional and the official form still sit above it.

Last formula review: 18 August 2026. Same inputs produce the same outputs. This page does not replace a disclosure, a Form 1040, a Closing Disclosure, or advice from someone who can accept a fiduciary duty. If the loans decision is large, print the inputs you used and take that sheet with you.
