Loan / Credit Calculator
Estimate payment, interest and total cost using consistent inputs before comparing lender offers.
Indicative calculation. This is not a financial offer.
How the loan calculation works
For a constant payment we use C = P × r × (1+r)ⁿ / ((1+r)ⁿ − 1), based on principal, monthly rate and number of payments. At a zero rate, principal is divided by the number of payments.
Illustrative example: A 10,000-unit loan at 6% nominal annual interest over 36 months gives an estimated payment of about 304 units. Fees, APR, insurance and lender rounding can change the actual figure.
FAQ
How do nominal rate and APR differ?
The nominal rate is applied to principal. APR combines interest and specified charges under an annual method, making it generally more useful for comparing offers.
What happens if I extend the term?
The monthly payment usually falls, but interest is paid for longer and total cost may rise.
Is a grace period free?
No. You may pay interest without reducing principal, or defer payments that become due later. Check the contract for its cost and duration.
Information to prepare
- The amount actually needed, not the maximum available.
- Nominal annual rate and APR for each offer.

How to read the result
- The payment is the estimated periodic amount.
- Total interest shows the combined effect of rate and term.
- Payment-to-income gives context but does not replace a full budget.
Common mistakes
- Comparing payments with different terms.
- Confusing nominal rate with APR.
- Treating a grace period as free months.
