Rota Hours Calculator

Advice for this situation

This tool is useful when a rota repeats and you want a quick weekly, fortnightly, or monthly sense check without rebuilding each day by hand. 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.

Monthly estimates are just that: estimates. Real calendar months do not line up perfectly with a flat four-week assumption. 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.

• Use paid hours per shift rather than gross hours if you want a cleaner comparison with payroll.
• Repeating rotas are easiest to review when the cycle length is recorded alongside the hours.
• If the rota alternates busy and light weeks, keep both the average and the peak week visible.
