Break Deduction Calculator

See how much break time changes paid working time. This is a free calculator built for quick repeat checks on mobile and desktop.

Advice for this situation

Use this when you want to see exactly how much split lunch and tea breaks reduce paid time without having to add them mentally. In the UK, unpaid lunch breaks normally only come out of paid time when you are genuinely relieved from work, average weekly hours are usually checked over a longer reference period, and overtime premiums often come from the contract rather than one universal statutory rate.

Break deductions become misleading when the real issue is whether the break was truly unpaid and uninterrupted. If your workplace uses paid breaks, on-call time, or shift differentials, compare the calculator result with your rota rule before treating the number as payroll-ready.

UK guidance on this page is a practical planning layer, not legal advice. If the answer affects pay, dismissal, leave entitlement, or a formal workplace process, verify it against the contract, policy, collective rule, or official guidance that applies to your role.

  • Keep presence time and paid time visible together if you are checking fairness or travel impact.
  • If breaks are interrupted by work, the policy treatment may differ from a clean unpaid deduction.
  • Multiple small breaks can add up quickly across a week even when each one looks minor in isolation.
