How We Calculate

A useful estimate starts with visible assumptions.

Your inputs drive the result

Each MathsData calculator uses the numbers you enter, such as balances, annual interest rates, terms, contributions and extra payments. Rates are annual percentages unless a calculator says otherwise.

Results are estimates

Results use standard mathematical formulas to illustrate the relationship between the inputs. Actual lender terms, fees, payment timing, compounding conventions, taxes, market changes and local rules may lead to a different outcome.

Check before relying

Review every input and the assumptions shown on the calculator page. For a decision with real financial consequences, confirm the figures with your lender, provider or a qualified professional.
