Timesheet Calculator
Add up a whole week of shifts — daily hours, unpaid breaks, overtime, and optional pay.
37.50 h across 5 days.
A timesheet calculator totals a week of shifts. For each day it takes the end time minus the start time, subtracts the unpaid break, and adds the days together. Five days of 09:00 to 17:00 with a 30-minute lunch is 7.5 h each, so 37.5 hours for the week.
How a weekly time card adds up
A weekly timesheet, or time card, records when you clock in and out on each day. For every day the calculator finds the gross span between the two times, removes any unpaid break such as a lunch, and clamps the result so a break longer than the shift never produces a negative number. Adding the seven daily figures gives your total weekly hours. Blank days count as zero, so you only fill in the days you actually worked.
Two extras are optional. An overtime threshold (40 hours a week by default) splits the total into regular and overtime hours. If you enter an hourly rate, the tool multiplies regular hours by the rate and overtime hours by the rate times an overtime multiplier (1.5× by default) to estimate pay.
If a day’s end time is earlier than its start time, add 24 hours first (overnight shift).
Worked example
Suppose you work Monday to Friday, 09:00 to 17:00, with a 30-minute unpaid lunch each day. Each day is 8 h gross minus 30 min, which is 7.5 h. Five days give 5 × 7.5 = 37.5 hours. Because 37.5 is under the 40-hour threshold, there is no overtime. At £12 an hour that is 37.5 × 12 = £450 for the week.
- 1 Enter each day’s clock-in and clock-out. For example, Monday 09:00 to 17:00. Leave a day blank if you did not work it.
- 2 Subtract each day’s unpaid break. 8 h gross − 30 min lunch = 7.5 h worked on that day. Paid breaks stay in, so leave them out of the break field.
- 3 Add the days for the weekly total. Five days at 7.5 h each is 5 × 7.5 = 37.5 hours for the week.
- 4 Split off overtime, if any. Hours above the threshold (40 h by default) are overtime. 37.5 h is under 40, so all of it is regular time.
- 5 Add a pay rate to estimate pay. Regular hours × rate, plus overtime hours × rate × the multiplier. 37.5 × £12 = £450.
Example week (09:00–17:00, 30-min lunch)
Each weekday is 8 h gross minus a 30-minute unpaid break, leaving 7.5 h. Blank weekend days add nothing.
| Day | Times | Break | Hours |

| Tue | 09:00–17:00 | 30 min | 7.50 |

Overtime, breaks, and estimates
Overtime rules vary. The 40-hour threshold and 1.5× multiplier are common defaults, but the real rules — daily versus weekly overtime, the exact multiplier, and which hours qualify — depend on your employer and your jurisdiction. Treat the split and any pay figure as an estimate and check your contract or local labour law for the numbers that apply to you.
Unpaid breaks and overnight shifts. Enter only breaks you are not paid for; a paid rest break stays part of your worked hours. When a shift crosses midnight — say 22:00 to 06:00 — the end time reads earlier than the start, so the tool adds 24 hours before subtracting, counting it as 8 hours rather than a negative span.
