About Finance
This collection has 54 ready-to-use tools for finance. Every tool runs in your browser, so the numbers you type are not sent to a server. Each page explains what to enter, shows the formula or method behind the result, and gives worked examples you can compare against your own figures.
Results are estimates for planning and comparison. Where rates, thresholds or rules change from year to year, the tool page states the tax year or assumptions it uses. Check them against an official source before you file, pay or sign anything.

Finance FAQ
Are these finance calculators financial advice?
No. They are estimates for planning and comparison. Check the assumptions on each page and confirm important decisions with a lender or qualified adviser.
Which formula do the loan calculators use?
Fixed-rate loan pages use the standard amortisation formula M = P × i × (1 + i)^n ÷ ((1 + i)^n − 1), where i is the periodic rate and n is the number of payments.
Do the results include fees and taxes?
Not unless the page says so. Most estimates exclude fees, insurance, taxes and rate changes, and each page lists what it leaves out.
