Time Card Calculator
Fill in your start time, end time and unpaid break for each day — days you didn't work stay blank. You get each day's hours, the weekly total in hours-and-minutes and payroll-ready decimal form, and gross pay if you add an hourly rate.
How a time card is totaled
Each day is end time minus start time minus the unpaid break; a shift that ends at or before its start time is treated as crossing midnight. Days are then summed in minutes and converted to decimal hours, which is what payroll software expects:
Overtime is not added automatically: US federal law (FLSA) requires 1.5× pay over 40 hours per week for non-exempt employees, and some states (notably California) add daily overtime over 8 hours. The steps give you the plain total; apply your overtime rules to it.
Worked examples
Example 1: a standard 9-to-5:30 week
Five days of 9:00–17:30 with a 30-minute lunch, at $20/hour.
- Each day.17:30 − 09:00 − 0:30 = 8.0 h
- Total the week.8 × 5 = 40 h
- Multiply by the rate.40 × $20 = $800 gross
40.0 hours, $800 gross pay.
Example 2: irregular part-time week
Mon 8:15–12:00 no break, Wed 13:30–19:45 with 15 min, Sat 10:00–14:00 no break.
- Each day in minutes.Mon 225; Wed 360; Sat 240
- Sum and convert.825 min = 13 h 45 min = 13.75 h
13.75 decimal hours for the timesheet.
Example 3: week with an overnight shift
Four day shifts of 8 h plus Friday 22:00–06:00 (no break).
- The Friday shift crosses midnight.06:00 + 24 h − 22:00 = 8 h
- Total.8 × 5 = 40 h
40 hours — the overnight shift counts on the day it starts.
FAQ
Why does payroll want decimal hours instead of hours and minutes?+
Pay is rate × time, and multiplication needs a decimal: 7 h 45 min at $20 is 7.75 × 20 = $155. Entering 7.45 instead of 7.75 would underpay by $6 — the single most common timesheet mistake.
Does the calculator handle overtime?+
It gives the raw weekly total. Apply your rules to it: under the FLSA, hours over 40/week get 1.5×; California adds daily overtime (over 8 h/day at 1.5×, over 12 at 2×). An overtime mode is on the roadmap.
Should I subtract my lunch break?+
Subtract unpaid meal breaks (usually 30+ minutes, fully relieved of duty). Short rest breaks of 5–20 minutes are normally paid under federal rules and should not be subtracted.
How do employers round time?+
Federal rules allow rounding to at most the nearest quarter hour, and it must be neutral over time (the 7-minute rule: 7 minutes round down, 8 round up). This calculator doesn't round — it totals exact minutes.
Can I use this for two weeks or a month?+
Run each week separately and add the totals — overtime is computed per workweek in the US, so mixing weeks into one total can hide overtime you're owed.
