— Free calculators · Tax year 2026/27 · No sign-up
Free UK pension, tax and bond calculators.
The calcs, free. The working, shown.
Every tool below runs the same engine and the same versioned tax-year config the signed-in suite uses — with the legislation and official-source citations on the page.
Your calculator inputs and results stay in this browser unless you choose to send them: a share link carries them in the link itself; downloading a PDF from the long-term care entitlement checker or the pension contribution net cost calculator sends them to our servers to build the file; and when you continue from the Pension IHT calculator to the full workbench, its figures (no names or contact details) are held on our servers under a single-use link for 7 days, so they survive a sign-in on another device. Sign in only when you want to rerun a calculation in a client workflow or create a supported export. How we verify the numbers.
