Where to start

Compare the cost of a salary sacrifice with the relief-at-source top-up for a personal contribution. Check the pension annual allowance separately; it is not the same as the earnings-based tax relief limit.

UK data and coverage

Pension rules have different income definitions, tapering and exceptions. These tools make their scope explicit; the estate tool needs confirmed available nil-rate bands rather than assuming eligibility.

Each calculator explains the formula, includes a worked example and identifies the assumptions that can affect your result. Official rule tables and dated price references are linked on the relevant pages.
