How this calculator works
Paid hours = shift duration − unpaid breaks. This simplified single-rate model uses 1.5× for hours above 40 in one workweek for covered nonexempt workers. It excludes daily overtime, state-specific rules, bonuses, multiple pay rates, paid leave and exemption determinations. Use the regular rate, which can differ from base pay. Gross pay is before taxes and deductions.

How to fill in your time card
- Enter your hourly rate. Use your base rate before any shift differential. If part of your week is paid at a different rate, see the regular-rate note below.
- Enter each day's start and end time from your schedule or clock-in records, in 24-hour or AM/PM form. Leave days you did not work blank.
- Enter unpaid break minutes for each day, such as a 30-minute lunch you were fully relieved from. Short paid rest breaks stay in your hours, so do not subtract them.
- Press Calculate. The calculator totals paid hours for the week, splits them into regular hours (up to 40) and overtime hours (over 40), and multiplies overtime by 1.5.
A shift that ends after midnight, such as 10:00 PM to 2:00 AM, is counted correctly as four hours. Enter each shift on the day it started.
Worked example: a standard 40-hour week
The example already filled in is a common office or warehouse schedule: Monday to Friday, 9:00 AM to 5:30 PM, with an unpaid 30-minute lunch, at $20 an hour. Each day is 8.5 hours on site minus 0.5 hours of lunch, or 8 paid hours. Five days make exactly 40 hours, so there is no overtime and gross pay is 40 x $20 = $800 for the week.
If the same worker skipped lunch one day and stayed on the clock, that day would count 8.5 hours and the week would total 40.5 hours: 40 regular hours at $20 plus 0.5 overtime hours at $30, or $815.
Worked example: overtime and an overnight shift
Here is a heavier week at $22 an hour. Monday to Thursday run 7:00 AM to 5:30 PM with a 30-minute unpaid lunch (10 paid hours each), Friday runs 8:00 AM to 2:15 PM with no break (6.25 hours), and Saturday is an overnight shift from 10:00 PM to 2:00 AM (4 hours).
| Hours | Rate | Pay | |
|---|---|---|---|
| Regular hours | 40.00 | $22.00 | $880.00 |
| Overtime hours | 10.25 | $33.00 | $338.25 |
| Total | 50.25 | $1,218.25 |
Federal law counts the whole workweek, not each day, so the long Monday to Thursday shifts do not create overtime on their own. Overtime starts only once the week passes 40 hours. Some states also pay daily overtime (see below), which would raise this total.
Converting minutes to decimal hours
Payroll systems multiply your rate by hours written as decimals, so 7 hours 45 minutes is 7.75 hours, not 7.45. Use this table to check a pay stub by hand.
| Minutes | Decimal hours | Minutes | Decimal hours |
|---|---|---|---|
| 5 | 0.08 | 35 | 0.58 |
| 10 | 0.17 | 40 | 0.67 |
| 15 | 0.25 | 45 | 0.75 |
| 20 | 0.33 | 50 | 0.83 |
| 25 | 0.42 | 55 | 0.92 |
| 30 | 0.50 | 60 | 1.00 |
To convert any time, divide the minutes by 60. For example, 8 hours 20 minutes is 8 + 20/60 = 8.33 hours.
Federal overtime rules in plain English
The Fair Labor Standards Act (FLSA) requires overtime of at least 1.5 times the regular rate for every hour over 40 in a workweek for non-exempt employees. A few rules decide how that works in practice:
- The workweek is fixed. Your employer sets a recurring 168-hour period, such as Sunday 12:00 AM to Saturday 11:59 PM. Each workweek stands alone; two weeks cannot be averaged, so 30 hours one week and 50 the next still earns 10 overtime hours.
- Only hours worked count. Paid holidays, vacation and sick days are not hours worked under federal law, so they do not push you over 40.
- The regular rate can be higher than your base rate. Non-discretionary bonuses, shift differentials and some incentive pay must be included when overtime is calculated. If you earn two rates in one week, overtime is usually based on the weighted average, so this calculator's single-rate result is a minimum estimate.
- Salaried does not always mean exempt. Exemption depends on both salary level and job duties. Many salaried workers are still owed overtime. The U.S. Department of Labor overtime page explains the tests.
States with daily overtime
A few states go further than the weekly federal rule. In those states a long single shift can earn overtime even if the week stays under 40 hours:
- California: 1.5 times pay for hours over 8 in a workday and for the first 8 hours on a seventh consecutive workday; double time for hours over 12 in a day and over 8 on that seventh day.
- Alaska: overtime after 8 hours in a day for most employers with four or more employees.
- Nevada: overtime after 8 hours in a 24-hour period for employees earning less than 1.5 times the state minimum wage, unless an alternative schedule was agreed.
- Colorado: overtime after 12 hours in a workday or 12 consecutive hours.
This calculator uses the federal weekly rule only. In these states, count daily overtime separately and add it, or ask your payroll department how they apply the state rule.
Breaks, meal periods and rounding
Federal rules treat short rest breaks of about 5 to 20 minutes as paid working time. A bona fide meal period, usually 30 minutes or more, can be unpaid only if you are completely relieved of duty; eating at your desk while answering calls is work time. Many states, including California, Washington and New York, also require meal breaks for longer shifts.
Employers may round clock times to the nearest 5 minutes, tenth of an hour or quarter hour, but only if the rounding is neutral over time and does not consistently cut hours. If your time records are always rounded down, compare them with your own notes.
From gross pay to take-home pay
This calculator stops at gross pay. Federal income tax, Social Security (6.2%), Medicare (1.45%) and any state or local tax come out of that amount, and overtime is taxed the same way as regular wages. For tax years 2025 through 2028, qualifying workers can also deduct up to $12,500 of overtime premium pay ($25,000 if married filing jointly) on their federal return, with the deduction phasing out at higher incomes; see the tips and overtime deduction calculator.
To see your net pay per check, put the weekly gross from this page into the weekly paycheck calculator, or use the overtime pay calculator to compare take-home pay with and without extra hours.
Keep your own records
Employers must keep accurate records of hours worked and wages paid for non-exempt employees, but mistakes happen. Write down your start, end and break times each day, or keep photos of the schedule and time clock. If your pay stub shows fewer hours than you worked, raise it with payroll first, then with your state labor department or the federal Wage and Hour Division if it is not fixed. Wage claims generally have deadlines of two to three years under federal law, so do not wait.
Hourly rate to weekly and yearly pay
For a quick check, here is what common hourly rates pay before tax for a 40-hour week, for a full year of 2,080 hours, and for a year that adds five overtime hours every week.
| Hourly rate | 40-hour week | Year (2,080 hours) | Year with 5 OT hours a week |
|---|---|---|---|
| $15 | $600.00 | $31,200 | $37,050 |
| $18 | $720.00 | $37,440 | $44,460 |
| $20 | $800.00 | $41,600 | $49,400 |
| $25 | $1,000.00 | $52,000 | $61,750 |
| $30 | $1,200.00 | $62,400 | $74,100 |
| $40 | $1,600.00 | $83,200 | $98,800 |
Five overtime hours a week adds 18.75% to yearly gross pay, because each overtime hour is paid at 1.5 times the base rate. Use the hourly to salary calculator to convert any rate, including after-tax pay.
Time card terms
- Workweek: the fixed seven-day period your employer uses to count overtime.
- Regular rate: your hourly pay including non-discretionary bonuses and differentials, used to price overtime.
- Non-exempt: an employee entitled to overtime under the FLSA.
- Bona fide meal period: an unpaid break, usually 30 minutes or more, with no work duties.
Checking your pay stub
Compare the hours on your pay stub with this calculator's total for each workweek in the pay period. A biweekly stub covers two workweeks, and overtime must be counted separately for each one. Regular and overtime hours usually appear on separate lines with their own rates; the overtime rate should be at least 1.5 times your regular rate. Our pay stub guide explains each line.
Common time card mistakes
- Writing minutes as decimals. 8 hours 30 minutes is 8.5 hours, not 8.3.
- Subtracting paid breaks. Only unpaid meal breaks come off; short rest breaks are paid time.
- Splitting an overnight shift. Enter it once, on the day it started, so the hours are not lost or double counted.
- Using the wrong workweek. If your employer's week runs Wednesday to Tuesday, total those seven days, not Monday to Sunday.
- Forgetting work before or after the shift. Required pre-shift meetings and closing duties after clocking out are often hours worked.
Frequently asked questions
How do I calculate hours worked with a lunch break?
Subtract the start time from the end time, then subtract the unpaid break. 8:00 AM to 4:30 PM is 8.5 hours; minus a 30-minute lunch it is 8 paid hours.
Is overtime calculated daily or weekly?
Under federal law, weekly: hours over 40 in a fixed workweek. California, Alaska, Nevada and Colorado also have daily overtime rules for some workers.
Do paid holidays count toward overtime?
Not under federal law. Paid holidays, vacation and sick time are not hours worked, so they do not count toward the 40-hour threshold unless your employer or state rules say otherwise.
How do I convert 7 hours 45 minutes to decimal?
Divide the minutes by 60: 45/60 = 0.75, so 7 hours 45 minutes is 7.75 hours.
Does this include taxes?
No. It shows gross weekly pay. Use the weekly paycheck calculator to estimate take-home pay after federal, state and payroll taxes.
Does an overnight shift count on one day or two?
For overtime, only the workweek total matters. Enter the shift on the day it started; the calculator counts hours past midnight correctly.
