Loan & Credit Line Payment
This calculator helps determine your loan or credit line payment.
How the loan & credit line payment calculator works
It computes the same balance two ways: as a fully amortizing loan that clears over the term, and as an interest-only line where the payment covers just the interest. Seeing both makes the trade-off between a low payment and actually reducing the balance clear.
Worked example: with loan or line balance of $25,000, interest rate of 9.00% and term (years) of 5, the loan & credit line payment calculator shows amortizing payment of $518.96.
- Amortizing payment
- $518.96
- Interest-only payment
- $187.50
- Amortizing total interest
- $6,138
- Monthly difference
- $331.46
The formula
Amortizing payment = P × r ÷ (1 − (1 + r)⁻ⁿ). Interest-only payment = balance × monthly rate.

Questions about the loan & credit line payment
What is the difference between amortizing and interest-only payments?
An amortizing payment includes principal and clears the balance by the end of the term; an interest-only payment covers just the interest, so the balance never falls until you pay principal.
When does interest-only make sense?
For short-term flexibility or bridge financing where you have a clear plan to repay the principal — for example from a sale or bonus. As a long-term habit it keeps you in debt.
Which payment should I choose?
The amortizing payment if your goal is to be debt-free; interest-only only when low payments matter temporarily and you will repay principal deliberately.
Is the Loan & Credit Line Payment free to use?
Yes. Every calculator on FinCalculators is completely free, with no sign-up, login or paywall. You can run as many scenarios as you like.
