This time card calculator totals your work hours from clock-in and clock-out times — breaks deducted, days summed, and gross pay at your hourly rate — the timesheet math without the spreadsheet.

Payroll thinks in decimals: 8 h 30 m is 8.50 hours on a pay stub, not 8.30 — the decimal card is the one to compare against your employer’s system. Overtime tiers (time-and-a-half past 40) are handled by our Overtime Calculator; this tool gives the raw totals it builds on. Rounding: many employers round punches to the nearest 15 minutes (the “7-minute rule”) — check your handbook before disputing 0.05 h.

Clock Math Without the Head-Scratching

Worked time = (clock-out − clock-in) − unpaid breaks; payroll then wants it in decimal hours (minutes ÷ 60). Overnight shifts are handled (an out-time earlier than the in-time rolls past midnight). Tiered overtime pay builds on these totals in our Overtime Calculator. Part of our Everyday Life Calculators collection.

Worked Example (Verified)

  • 9:00 AM → 5:30 PM, 30-min lunch, 5 days, $20/h (defaults): 8.5 − 0.5 = 8 h/day → 40 h/week → $800 gross
  • Decimal trap illustrated: leave at 5:45 instead and the day is 8 h 45 m = 8.75 h — pay stubs multiply 8.75 × rate, and anyone reading it as "8.45" underpays themselves in their own audit
  • Overnight: 10:00 PM → 6:00 AM with 30 min break = 7.5 worked hours — the roll-past-midnight case paper time cards famously mangle
  • Four-day weeks: same day, 4 days = 32 h — compressed schedules reprice weekends without touching the daily math

Timesheet Hygiene

  • Record actual times, not scheduled times — the gap between them is where wage disputes and unpaid overtime live.
  • Paid vs unpaid breaks are jurisdiction-and-policy matters (short 5–20 min breaks are usually paid under US FLSA practice; bona fide meal periods usually aren't) — the calculator subtracts only what you tell it to.
  • Keep your own copy of hours (photo of the time card, notes app) — reconciliation against the stub is a five-minute habit that catches real money.
  • Salaried-exempt readers: the same math prices your effective hourly rate when a "40-hour" job quietly becomes 52.

Frequently Asked Questions

How do I calculate hours worked from a time card?

Subtract clock-in from clock-out, subtract unpaid break minutes, and convert to decimals for payroll (minutes ÷ 60). 9:00 to 17:30 minus 30 minutes = 8.00 decimal hours. This calculator handles overnight shifts and weekly multiplication automatically.

What is 8 hours 45 minutes in decimal hours?

8.75 hours (45 ÷ 60 = 0.75). The common error — writing 8.45 — shortchanges by 0.30 h per day, which compounds to real money across a pay period. The calculator always shows the decimal form alongside h:mm.

Are breaks deducted from hours?

Bona fide meal breaks (usually 30+ minutes, fully relieved of duty) are typically unpaid and deducted; short rest breaks are commonly paid under US practice. The calculator subtracts whatever unpaid break you enter — know your policy and local law to set it correctly.

How do employers round time?

Many round punches to the nearest 5, 10 or 15 minutes (federal rules permit neutral rounding, e.g. the 7-minute rule within quarter-hours) — it must average out fairly over time. If your stubs consistently round against you, that pattern itself is the issue to raise.

Does this calculate overtime?

It totals hours; overtime premium tiers (1.5× past 40 h/week in the US, daily rules in some states) are computed by our companion Overtime Calculator. Run the totals here, then price them there.
