Frequently asked questions
The short answers to what people ask most. Each calculator also has its own questions answered on its page.
- Is calcd free to use?
- Yes. Every calculator is free, with no account, sign-up or paywall.
- How accurate are the results?
- The calculators use current UK rates and standard formulas, and each one shows when it was last updated. The results are estimates to help you plan, not financial advice. Confirm anything important with HMRC, your lender or a qualified adviser before you act on it.
- Do you store the figures I enter?
- No. The calculations run entirely in your browser. The numbers you type are never sent to us or stored on our servers.
- Which calculators can I use right now?
- All 23 of them. They cover take-home pay, mortgages, stamp duty, savings, pensions, debt, dividends, corporation tax and capital gains tax, and you'll find the full list on the calculators page.
- Does calcd work outside the UK?
- No, calcd is built specifically for UK rules. For example, stamp duty here covers England and Northern Ireland; Scotland and Wales use their own systems.
- Do you use cookies or tracking?
- No cookies at all, which is why the site never asks you about them. We use PostHog in cookieless mode to count pages and clicks: it stores nothing on your device and identifies nobody. We do not record the page itself, so there are no session replays, and the parts of a page showing your own figures are excluded from click tracking. We do not run advertising trackers. The Cookie Policy explains how counting works without an identifier.
