Time Card Calculator

Blake Boege
Written by Blake Boege · Founder, Calculator Answers

A time card calculator is a productivity tool used to calculate an employee's total hours worked, overtime, and estimated gross pay for a given pay period. By entering daily clock-in and clock-out times alongside unpaid break durations, the tool tallies the net time. It applies configured overtime thresholds and hourly wage rates to generate a pay breakdown. Small business owners, freelancers, and payroll personnel use it to verify timesheets and estimate labour costs.

Enter a start time, end time, and unpaid break minutes for each day of the week. The calculator totals daily and weekly hours, splits them into regular and overtime, and estimates gross pay.

Examples

9:00 AM to 5:00 PM, Mon to Fri, 30 min break

= 37.50 paid hours · gross pay $750.00

45 hours total at $20/hr, 1.5× OT

= $800 regular + $150 OT = $950 gross

Six 8 hour days, 30 min break each, $18/hr

= 40 regular + 5 OT = $810 gross

How it works

Daily paid hours are the end time minus the start time minus any unpaid break. Weekly paid hours are the sum across the seven days. Overtime hours are everything above your weekly threshold, usually 40.

Daily and weekly hours

daily hours = end time − start time − break time

weekly hours = sum of daily hours

overtime hours = max(total hours − 40, 0)

Gross pay

regular pay = regular hours × hourly rate

overtime pay = overtime hours × hourly rate × OT multiplier

gross pay = regular pay + overtime pay

What is a time card calculator?

A time card calculator turns the start and end times you worked, plus your breaks, into a tidy weekly total: regular hours, overtime hours, and an optional gross pay estimate. It replaces the manual math of adding up shifts in a notebook or spreadsheet, and is useful for hourly workers, contractors, and small businesses.

How the time card calculator works

Fill in the start time, end time, and unpaid break minutes for each day you worked. Leave both time fields blank for an off day. The calculator then:

  • Computes paid hours for each day from the formula above.
  • Sums the days into total weekly paid hours.
  • Splits the week into regular and overtime hours using the weekly threshold you set (default 40).
  • Multiplies hours by your hourly rate and the overtime multiplier (default 1.5×) to estimate gross pay.

How to calculate work hours

The basic rule is end time minus start time minus unpaid break. For example, 9:00 AM to 5:00 PM is 8 hours of elapsed time. Subtract a 30 minute unpaid lunch and the day pays for 7.5 hours. If your shift crosses midnight, split it across two days or use a separate overnight tool. This calculator currently does not roll over past midnight automatically.

How breaks affect paid hours

Only enter unpaid break minutes here. Paid breaks should stay at 0 because they do not reduce the hours you are paid for. A common pattern is a 30 minute unpaid lunch on shifts longer than 6 hours, but the rules vary by state and employer.

Regular hours vs overtime hours

In the standard U.S. weekly rule, the first 40 hours each week are regular hours and anything above 40 is overtime, paid at the overtime multiplier. Some states and union contracts use daily overtime instead (such as anything over 8 hours in a day). This calculator uses a simple weekly threshold, which is the most common case.

For a deeper look at how overtime pay scales with the rate and multiplier, see the overtime calculator.

Gross pay estimate

Gross pay is hours times rate, with overtime hours paid at the higher rate. Add your hourly rate to see the estimate in the result panel. Gross pay is before taxes and withholdings, so your actual take-home pay will be lower.

Worked example

Monday through Friday: 9:00 AM to 5:00 PM with a 30 minute break each day, $20 per hour, overtime threshold 40, overtime multiplier 1.5×.

  • Daily paid hours: 8 − 0.5 = 7.50 hours per day
  • Weekly paid hours: 5 × 7.5 = 37.50 hours
  • Regular hours: 37.50
  • Overtime hours: 0.00
  • Gross pay: 37.5 × $20 = $750.00

A simple overtime example: 45 total hours at $20 per hour with a 1.5× multiplier:

  • Regular pay: 40 × $20 = $800.00
  • Overtime pay: 5 × $20 × 1.5 = $150.00
  • Gross pay: $800.00 + $150.00 = $950.00

Common mistakes

  • Entering paid breaks (like a 15 minute rest break) as if they were unpaid, which understates paid hours.
  • Treating gross pay as take-home pay. Gross is before taxes and benefits.
  • Assuming daily overtime rules apply when your state and employer use weekly overtime, or vice versa.
  • Mixing 12 hour AM/PM times by hand. Use the time inputs to avoid 1:00 vs 13:00 errors.
  • Crossing midnight in one shift. Split the shift across two days so each side stays positive.

Frequently asked questions

Subtract the start time from the end time, then subtract any unpaid break minutes. For example, 9:00 AM to 5:00 PM with a 30 minute break gives 8 hours minus 0.5 hours = 7.5 paid hours. Repeat for each day and sum the daily totals to get weekly hours worked.

Unpaid breaks reduce paid hours. If you take a 30 minute unpaid lunch on top of an 8 hour shift, your paid hours for that day are 7.5, not 8. Paid breaks do not reduce paid hours and should usually be set to 0 in this calculator. Federal law in the U.S. does not require meal or rest breaks, but many states and employers do.

In the standard U.S. weekly rule, overtime hours are the hours worked in a single week beyond 40. With this calculator, set the overtime threshold (default 40) and any weekly hours above that count as overtime. Some states and employers use daily overtime rules instead, which this simple weekly calculator does not model.

Time and a half is a 1.5× overtime multiplier. Every overtime hour is paid at 1.5 times the regular hourly rate. For example, at $20 per hour, overtime is paid at $30 per hour. Some jobs use double time (2×) for certain hours, holidays, or premium shifts.

Gross pay is regular hours times the hourly rate, plus overtime hours times the rate times the overtime multiplier. For example, 40 regular hours at $20 plus 5 overtime hours at $20 × 1.5 = $800 + $150 = $950. Gross pay is before taxes and withholdings.

Not in this version. If you enter an end time earlier than the start time, the calculator shows a validation message rather than silently rolling past midnight. To track an overnight shift, split it into two entries (one ending at 11:59 PM and the next starting at 12:00 AM) or use a more advanced timesheet.

It depends on your employer, state, and the length of the break. In the U.S., short rest breaks (5 to 20 minutes) are typically paid, while bona fide meal periods of 30 minutes or more are often unpaid. Enter only the unpaid break minutes in this calculator so that paid hours come out right.

No. This calculator estimates gross pay from a weekly time card. A full payroll calculator also handles federal, state, and local taxes, Social Security, Medicare, retirement deductions, and benefits. For final paycheck numbers, use your employer's payroll system or a dedicated payroll tool.
