Gross Pay$1,000.00
This time card calculator totals worked hours from a week of clock-in and clock-out times, then splits them into regular and overtime hours to compute gross pay. Each shift is measured to the minute, with overnight shifts handled automatically when clock-out is earlier than clock-in. Overtime above your weekly threshold is paid at the standard time-and-a-half rate.
Formula
gross = regular × rate + overtime × rate × 1.5 ; overtime = max(0, total − threshold)
- total
- Sum of all shift durations for the week, in hours
- threshold
- Weekly hours before overtime begins (e.g. 40)
- overtime
- Hours worked beyond the threshold
- regular
- Total hours minus overtime hours
- rate
- Hourly pay rate; overtime is paid at 1.5× this rate
How it works
- Enter each day's clock-in and clock-out times in 24-hour HH:MM form. A clock-out at or before the clock-in is treated as crossing midnight, adding 24 hours.
- Set your hourly rate and the weekly overtime threshold (commonly 40 hours).
- The calculator sums each shift's duration into total hours, classifies anything above the threshold as overtime, and computes gross pay as regular hours at your rate plus overtime hours at 1.5× the rate.
Worked example
Five shifts of 8.5, 8, 10, 8, and 9 hours at $25/hr with a 40-hour overtime threshold.
- Total hours: 8.5 + 8 + 10 + 8 + 9 = 43.5.
- Overtime: 43.5 − 40 = 3.5 h; regular: 40 h.
- Gross pay: 40 × 25 + 3.5 × 25 × 1.5 = 1000 + 131.25.
43.5 total hours, 40 regular and 3.5 overtime, for $1,131.25 gross pay.
Frequently asked questions
- How does the calculator handle overnight shifts?
- If a shift's clock-out time is the same as or earlier than its clock-in time, the calculator assumes the shift crossed midnight and adds 24 hours, so a 22:00 to 06:00 shift correctly counts as eight hours.
- How is overtime pay calculated?
- Hours above your weekly threshold are overtime, paid at 1.5 times the hourly rate. Hours up to the threshold are regular pay. The threshold is commonly 40 hours but you can set it to match your rules.
- Does this account for unpaid breaks?
- No. It measures the full span from clock-in to clock-out. If you take unpaid breaks, adjust the clock times or subtract that time separately, since the calculator counts the whole shift.
- Is the gross pay before taxes?
- Yes. Gross pay is your earnings before any tax, benefit, or other deductions. To estimate net take-home pay you would apply withholding separately.
