Time Card Calculator

Free weekly time card calculator: enter clock-in, clock-out, and break minutes for each day. Get daily totals, the weekly total in decimal hours, and gross pay with the overtime split at 40 hours — no signup, nothing stored.

How to Use This Time Card Calculator

1. Enter clock-in and clock-out times for each day you worked — skip days off. Overnight shifts (out-time earlier than in-time) are handled automatically.
2. Add unpaid break minutes per day — meal breaks only; short paid rest breaks stay in.
3. Optionally enter your hourly rate: the calculator splits regular and overtime pay at 40 hours and totals your gross.
4. Copy the result for your records — a private log beats every payroll dispute.

How the Totals Are Calculated

Daily Hours = (Clock Out − Clock In) − Unpaid Break

Weekly Total = Σ daily hours, displayed in decimal (minutes ÷ 60) because payroll multiplies decimals against rates. Hours beyond 40 pay at 1.5x when overtime is enabled — the FLSA federal standard for non-exempt employees. Daily-overtime states (California and others) need the daily split too; see the ladder in the double time calculator.

Worked Example — A Full Week

At $20/hour with overtime: 40 × $20 = $800, plus 6 × $30 = $180 → $980 gross. Without the overtime split, the same week would be underpaid by $60 — the exact error manual timesheets invite.

Time Card Rules Worth Knowing

• Rounding: employers may round punches to the nearest quarter-hour under the 7-minute rule, but rounding must be neutral over time. Keep exact times in your own log.
• Breaks: 5–20 minute breaks are paid (don't deduct); bona fide 30+ minute meals fully relieved of duty are unpaid. Working lunches count as work.
• Auto-deducted lunches: systems that always subtract 30 minutes even when you worked through are a classic wage violation — track reality, not the default.
• Pre/post-shift duties (setup, closing, mandatory gear) are compensable and belong on the card.

Common Time Card Errors (and What They Cost)

• Minutes written as decimals: 8:20 entered as "8.20" instead of 8.33 loses 8 minutes/day — over a year at $20/hour, roughly $700. The conversion chart lives in the timesheet to decimal converter.
• Missed midnight crossover: night shifts computed as negative or 12 hours short. This calculator adds 24 hours automatically when out-time precedes in-time.
• Weekly averaging: pairing a 46-hour week with a 34-hour week to dodge OT is illegal — each week stands alone (details in the overtime pay calculator).
• Unlogged remote minutes: answering work messages at home is work time if the employer knows — those scattered 15-minute blocks add up to real overtime.

For Freelancers and Contractors

The same card works for billables: enter your project hours, put your bill rate in the rate field, and set overtime to "No" (client work rarely has OT). Bill in decimal hours with 6-minute (0.1 hr) increments — the professional standard — and keep the copied weekly results as backup for invoice disputes. One tip: track by client per week (run the card once per client) rather than mixing projects in one card.

For Employers: Clean Time Card Practices

• Record exact punches, round only per lawful policy, and never auto-deduct meals without an attestation step.
• Review weekly, not at pay-period end — memory-based corrections two weeks later are guesswork and legal exposure.
• Keep records 2–3 years minimum (FLSA requires 2 years for time cards, 3 for payroll records).
• Reconcile differentials and premiums: night and holiday hours need their multipliers applied to the differential-inclusive rate — the top audit finding in shift-differential workplaces.
