Calculate gross shift duration, breaks, paid hours, and decimal hours. This is a free calculator built for quick repeat checks on mobile and desktop.
This is the classic calculator for working out how many paid hours are really inside a shift once breaks and overnight boundaries are included. 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.
The most common mistake is forgetting to tell the calculator that the shift finishes the next day. 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.
