Mode
Rounding is applied to paid time. In weekly mode, it is applied per day before weekly totals are calculated.
These are editable planning rules, not automatic legal rules. Confirm local payroll policy before relying on the result.
Use this mode when you have one clock-in / clock-out shift and want to subtract an unpaid break.
Break duration should not exceed the raw shift duration.

Weekly mode is best for Monday-Sunday summaries. One shift per day is acceptable for v1.
Use this mode when you already know the total worked time and only need the regular/overtime split.
When to use this page
- Use this page when the answer depends on clock-in / clock-out times, unpaid breaks, overtime thresholds, or an hourly rate.
- Use Time Add instead when you only need to add and subtract raw durations without wall-clock shift logic.
What this calculator does not do
- No taxes, deductions, holiday premiums, or union rules.
- No timezone, DST, or calendar-date logic.
- Planning estimate only unless you verify the rule set against your local payroll policy.
How it’s calculated
- Single-shift mode converts start and end times into minutes, subtracts unpaid break time, then applies the chosen rounding increment.
- Weekly mode calculates each enabled day first, then sums rounded daily times and applies daily and/or weekly overtime logic without double-counting.
- Known total mode starts from a duration such as 47:30 and splits regular vs overtime hours using the weekly threshold.
- Estimated gross pay = regular hours × hourly rate + overtime hours × hourly rate × overtime multiplier.
FAQ
Does this calculator handle overnight shifts?
Yes. Turn on the overnight option when a shift ends after midnight. Without that toggle, an end time earlier than the start time should be treated as invalid.
How does weekly overtime avoid double-counting daily overtime?
When both daily and weekly overtime are enabled, the calculator subtracts already-counted daily overtime from the weekly overtime candidate before adding any extra weekly overtime.
Can I use this for legal or payroll compliance?
Use it for planning and quick checks. Local rules for overtime, holidays, premiums, and rounding may differ, so confirm the result against your employer or official payroll guidance.
What should I do if I already know my total hours?
Use Known total hours mode. If you first need to total several durations, use Time Add and then bring the result back here for the pay split.
