Time Card Calculator

Enter a clock-in, clock-out and unpaid break for each day worked, and this adds up the week and splits the total into regular and overtime hours.

Step-by-step proofCheck by hand
This is an informational total, not a payroll calculation. The 40-hour weekly overtime split shown here is a common convention, not a universal rule — overtime eligibility and the correct threshold (daily, weekly, or both) vary by jurisdiction, employer policy and employment classification. Check your pay stub, employment agreement or local labor law for the rules that actually apply to you.

How the weekly total is worked out

Each day's row is worked out exactly like the standalone Hours Calculator: clock-out minus clock-in, minus the unpaid break, with an overnight shift that crosses midnight handled automatically. A day left blank counts as 0 hours, not an error. The seven days are then added together, and the weekly total is split into regular and overtime hours at 40 hours.

The formula

weekly total = Σ (daily net hours), for each of the 7 days

Worked example

Five days of 9:00 AM to 5:00 PM with a 30-minute lunch break is 7.5 hours a day — 37.50 hours for the week, all within the regular 40-hour threshold.

Frequently asked questions

How is the weekly total calculated?
Each day's net hours are calculated the same way as the standalone Hours Calculator — clock-out minus clock-in, minus any unpaid break, with an overnight shift crossing midnight handled automatically — and the seven days are then added together.
What if I didn't work every day?
Leave both the clock-in and clock-out fields blank for any day off — it's treated as 0 hours for that day, not as an error. An error is only shown if just one of the two times is filled in for a day.
Why 40 hours for overtime, and not 8 hours per day like the Hours Calculator?
Weekly overtime (over 40 hours in a single work week) is the more common threshold for a time card, while the standalone Hours Calculator's 8-hour line is a per-shift daily threshold — the two are different conventions for different situations, and neither is a universal legal rule. Confirm which applies to you with your employer or local labor law.
