From quick currency lookups to loan maths, these pages help you translate rates and amounts without a spreadsheet. Fiat and crypto converters fetch live mid-market rates when you load them; calculators for mortgage, loan, interest, inflation, and salary run entirely offline with fixed formulas shown on each page. For FX context see Currency exchange rates explained; for shopping maths see Percentages, discounts, and VAT.
Repayment calculators assume level payments and a constant annual rate unless stated otherwise. They exclude taxes, insurance, arrangement fees, and early-repayment penalties — useful for comparing scenarios, not a substitute for a lender’s formal illustration. For property loans, read How mortgage payments work then model numbers in the Mortgage calculator.
Everyday helpers — tips, discounts, VAT, unit price, trip fuel — sit alongside longer-horizon tools like debt payoff and break-even. Pick the page that matches the question; each links to related calculators at the bottom.
