Estimate only. Overtime eligibility and pay requirements can vary under US federal or state law, by occupation and by your employment circumstances. Not every worker automatically receives 1.5× pay after 40 hours.

The basics

How to calculate work hours

For a shift without a break, subtract clock-in from clock-out. For a shift with an unpaid lunch, subtract the break duration too. This time card calculator does the same calculation for each completed day and adds the results for your selected pay period.

Work hours = clock-out − clock-in − unpaid break time

When the clock-out time is earlier than the clock-in time, the shift is treated as an overnight shift crossing midnight.

Breaks

Lunch and break deductions

If you know when lunch started and ended, enter both times for an exact deduction. If your workplace uses a standard unpaid lunch but you did not record it, enable automatic break deduction. It only applies when no manual break is entered.

Payroll

How to calculate overtime

Set the overtime threshold used for your estimate. The default is 40 hours per week, and the default multiplier is 1.5×. The calculator applies these settings separately to each week in biweekly mode.

Clarity

Regular vs overtime hours

Regular hours fill the weekly threshold first. Hours beyond that threshold are shown as overtime hours. A custom threshold or multiplier can be useful when checking a different payroll policy or jurisdiction.

Quick conversion

Hours and minutes to decimal hours

Payroll systems often use decimal hours instead of hours and minutes. Divide minutes by 60 and add them to the whole hours. For example, 7 hours 30 minutes is 7 + (30 ÷ 60) = 7.50 decimal hours. The calculator shows both formats.

Worked example

Example weekly time card

Monday–Friday9:00 AM–5:30 PM, 30-minute lunch8h × 5 = 40h
Saturday9:00 AM–1:00 PM, no break4h overtime
Weekly result40 regular hours + 4 overtime hours$1,150 at $25/hour and 1.5× OT

This is an illustration of the calculator’s arithmetic, not a determination of overtime eligibility. Employer policies and applicable law may produce a different payroll result.

Choose a period

Weekly vs biweekly time cards

A weekly time card is useful for a standard Monday–Sunday workweek and quick payroll checks. A biweekly time card gives you two consecutive weeks in one view. Because overtime is commonly assessed by workweek, the calculator applies the threshold to Week 1 and Week 2 independently rather than combining all 14 days.

Questions, answered

Time card calculator FAQs

How does the time card calculator work?

Enter clock-in, break and clock-out times for each day. The calculator subtracts a recorded or optional automatic break, totals completed shifts, converts hours to decimals and estimates regular and overtime pay when you add an hourly rate.

Can I use this as a weekly or biweekly time card calculator?

Yes. Weekly mode shows Monday through Sunday. Biweekly mode adds a second Monday through Sunday week and applies the overtime threshold independently to each week.

How are lunch and break deductions handled?

If you enter both break-out and break-in times, the calculator subtracts that exact break. You can also enable an automatic deduction for days without a recorded break. A manual break takes precedence over the automatic deduction.

Does overtime always start after 40 hours?

The default threshold is 40 hours per week because it is a common US payroll setting, but overtime rules depend on federal and state law, occupation and employment circumstances. You can change the threshold and multiplier to match your payroll assumptions.

Can it calculate an overnight shift?

Yes. When a clock-out time is earlier than its clock-in time, the calculator treats the shift as crossing midnight. Break times are aligned in the same way when they are entered.
