horacalcFree Time Card Calculator (weekly or biweekly)
Enter clock-in, clock-out and lunch for each day. The time card calculator totals your hours, counts overtime over 40 hours a week (or over 8 a day if you choose) and works out gross pay.

- Overtime (1.5×)

- Regular pay
- $800.00
- Overtime pay

Overtime is counted per workweek (Sunday–Saturday), never averaged over two weeks. Gross pay before taxes and deductions.
Example: a 43.5-hour week at $20.00 an hour
- Monday to Thursday, 8:00 AM to 5:30 PM is 9 h 30 m; minus a 30-minute lunch, that is 9:00 a day, or 36:00 for the four days.
- Friday, 8:00 AM to 4:00 PM minus 30 minutes of lunch is 7:30. Week total: 36:00 + 7:30 = 43:30, or 43.5 hours.
- Overtime over 40 hours: 43.5 − 40 = 3.5 hours. Regular hours: 40.
- Pay: 40 × $20.00 = $800.00 regular; 3.5 × $20.00 × 1.5 = $105.00 overtime (the overtime rate is $30.00 an hour).
Result: 43:30 hours (40 regular + 3.5 overtime), gross pay $905.00.
How to use the time card calculator (time clock calculator)
Pick Week or 2 weeks, then enter clock-in, clock-out and lunch (or other unpaid breaks) for each day you worked, just as your time clock recorded them. Leave days off blank. Times can be typed as 8:00 AM, 8a, 800 or 17:30, and lunch in minutes (30) or as 0:45. Copy Monday fills the other weekdays with Monday’s hours, so a regular schedule takes a few seconds.
Under Overtime, pay rate and rounding you set:
- Overtime after (hours per week): 40 by default, as in the federal FLSA.
- Daily overtime after: empty by default. Enter 8 for California-style daily overtime.
- Overtime rate: 1.5 (“time and a half”) by default; enter 2 for double time.
- Hourly rate: optional. With it, the result shows regular pay, overtime pay and gross pay.
- Round punches: none, or to 5, 6, 10 or 15 minutes.
The week starts on Sunday, like most US payroll weeks. A shift that ends after midnight counts on the day it started. For a single long stretch, such as a 30-hour shift or a trip, use Date & time span: from 10:00 PM on Oct 27 to 6:15 AM on Oct 29 is 32 h 15 m.
Overtime rules the calculator applies
Under the Fair Labor Standards Act, covered non-exempt employees must be paid at least one and a half times their regular rate for every hour over 40 in a workweek. A workweek is a fixed period of seven consecutive days, and each week stands alone: hours are never averaged over two weeks, even if you are paid biweekly. That is why the biweekly view counts overtime for week 1 and week 2 separately.
Some states add a daily limit. In California, non-exempt employees get overtime for hours over 8 in a workday, and the calculator can apply that with the daily setting. Daily overtime is counted first; the weekly 40-hour rule then applies only to the hours that were not already overtime.
| Week | Hours worked | Regular | Overtime at 1.5× |
|---|---|---|---|
| 5 × 8:00 | 40:00 | 40:00 | 0:00 |
| 5 × 9:00 | 45:00 | 40:00 | 5:00 |
| 4 × 10:00 (daily limit 8) | 40:00 | 32:00 | 8:00 |
| 45:00 + 35:00 (biweekly) | 80:00 | 75:00 | 5:00 |
These are the general federal and California rules as the calculator applies them, not legal advice. Exempt employees, other states’ rules and union contracts can differ.
From hours to pay
Pay is calculated from decimal hours: 43:30 is 43.5 hours. Regular pay is regular hours × hourly rate, and overtime pay is overtime hours × hourly rate × the overtime rate. With $20.00 an hour, 40 regular hours pay $800.00 and 3.5 overtime hours pay $105.00, so gross pay is $905.00 before taxes and deductions. If you need decimal hours for something else, the decimal hours converter has a full minutes table.
Punch rounding
Many time clocks round punches. The calculator rounds each clock-in and clock-out to the nearest step before it does anything else, and shows the rounded times under each day. With 15-minute rounding, 7:53 becomes 8:00 and 7:52 becomes 7:45. The federal rule (29 CFR 785.48) accepts rounding to the nearest 5 minutes, tenth of an hour or quarter hour as long as it averages out and does not, over time, cut the hours employees actually worked.
Need only one day? The hours calculator works out a single shift with several breaks and can send the day to this time card.

FAQ
How do I calculate my hours on a time card?
For each day, subtract clock-in from clock-out, then subtract your unpaid lunch. Add the days for the week total. 8:00 AM to 5:30 PM with a 30-minute lunch is 9:00; four such days plus a 7:30 Friday make 43:30. The calculator does the math and shows decimals for payroll.
How is overtime calculated?
Under the federal Fair Labor Standards Act, non-exempt employees get at least 1.5 times their regular rate for hours over 40 in a workweek. At $20.00 an hour, 3.5 overtime hours pay 3.5 × $30.00 = $105.00. The 40 hours and the 1.5 are editable because some contracts pay more.
How does a biweekly time card handle overtime?
Choose “2 weeks”. Overtime is counted for each workweek separately, never averaged: 45 hours in week 1 and 35 in week 2 is 80 hours with 5 hours of overtime, not zero. The result lists both weeks and the two-week total.
What about daily overtime, like in California?
Fill in “Daily overtime after” with 8. Hours over 8 in a day then count as overtime first, and weekly overtime applies to the remaining regular hours, so no hour is counted twice. California also pays double time after 12 hours a day and on some seventh days; the calculator does not apply those rules.
Can the calculator round punches?
Yes. Choose rounding to 5, 6, 10 or 15 minutes. Federal rules allow rounding to the nearest 5, 6 or 15 minutes if, over time, it does not shortchange employees; 7:53 rounds to 8:00 and 7:52 to 7:45 with 15 minutes.
Can I save or print my time card?
Your entries stay in this browser for your next visit, and the share link reproduces the whole card. Download a CSV file for Excel or Google Sheets, or print it; most browsers can save the printout as a PDF.
