How it works
How to use the Loan Calculator tool
- 1
Pick what to solve for
Payment, loan amount or tenure.
- 2
Enter the known values
Rate plus amount, tenure or affordable payment.
- 3
Read the answer
With total interest and total repaid.
Formulas used
Payment uses the standard amortisation formula P·r·(1+r)ⁿ / ((1+r)ⁿ − 1). Affordable principal inverts it: P = payment × (1 − (1+r)⁻ⁿ) / r. Tenure solves n = −ln(1 − rP/payment) / ln(1 + r).
Limitations
We’d rather be upfront about what this tool can’t do yet:
- Assumes a fixed interest rate and equal monthly payments.
- Fees, insurance and prepayment charges aren’t included.
