How this calculator works

This loan calculator estimates fixed monthly repayments using the standard amortisation formula. It is useful for comparing different loan amounts, repayment terms and interest rates. Real lender quotes may include fees, different compounding methods and credit-score-based pricing.

Worked example

Change the default figures to match your situation, then run the calculation. For planning, test at least three scenarios: a conservative case, a likely case and a stretch case. This helps avoid relying on one optimistic number.

Common mistakes

  • Using headline rates without checking fees or eligibility.
  • Ignoring inflation, tax treatment or future income changes.
  • Comparing monthly cost only, without checking total cost over time.
