Calculators.

Work out your own numbers, on current 2026/27 figures, before you speak to anybody


Every calculator here runs on the same verified set of 2026/27 rates and allowances, so the answers agree with each other. Nothing is gated, nothing asks for your email, and none of it is stored.

These are a starting point rather than advice. If a number surprises you, that is usually worth a conversation.
