Pay Time Calculator UK
Pay time calculators are most useful when you need to turn real shift patterns into gross pay without doing the arithmetic by hand. This page calculates paid hours from start time, end time and unpaid break, then converts them into shift pay and weekly pay.
It is aimed at employees checking rota pay, supervisors pricing cover and small businesses making quick payroll sense-checks.

How this calculator works
The calculator converts the shift into paid hours by subtracting the unpaid break from the full time between start and finish. It then multiplies those hours by the hourly rate and the number of shifts you work per week.
That makes it a practical tool for rota checking, shift-cover planning and simple payroll review when you want to sense-check whether the gross pay line looks right.
Worked example
A 9:00 to 17:30 shift with a 30-minute unpaid break produces 8 paid hours, not 8.5. At £15.50 an hour, the daily gross pay is £124.
Multiply that by five similar shifts and the weekly gross becomes a number you can check against a timesheet or rota forecast.
2025/26 rates, thresholds, and inputs
The page focuses on gross pay from hours worked. If you need net pay after deductions, take the annualised gross result into a pay-check or salary calculator.
| Input | Use |
|---|---|
| Start and finish time | Sets the gross shift length |
| Unpaid break | Removes non-paid time |
| Hourly rate | Converts time into gross pay |
| Shifts per week | Produces a weekly cost or pay estimate |
Edge cases and assumptions
- Overnight shifts are supported by rolling the finish time into the next day.
- The calculator does not include overtime premiums or unsocial-hours uplifts.
- If your break is partly paid, reduce the unpaid-break figure accordingly.
- Annualised gross assumes the same weekly pattern all year.
FAQs
Can this calculator handle overnight shifts?
Yes. If the end time is earlier than the start time, the tool treats the shift as crossing midnight.
Does it calculate overtime?
Not directly. It calculates core gross pay from hours, rate and breaks.
Is the result gross or net pay?
Gross pay. Use a pay-check or salary calculator for deductions.
Sources and methodology
This page uses time-worked arithmetic rather than tax rules. It is intended for gross-pay checking from actual shift hours.
The annualised figure is only a quick planning aid and assumes the weekly pattern repeats consistently.
