Split a week's daily hours into regular and overtime hours.
40
This calculator sums a week's daily hours worked and splits the total into regular and overtime hours at a threshold you set (40 hours/week by default, the US federal standard) -- a pure hours-split calculation, distinct from a dollar-focused overtime pay calculator.
Enter hours worked for each day of the week and your overtime threshold. The result shows total hours, regular hours (up to the threshold), and overtime hours (anything beyond it).
Regular hours = min(total weekly hours, threshold). Overtime hours = max(0, total weekly hours - threshold). This matches the standard weekly-overtime rule used by many employers and jurisdictions (though some places calculate overtime daily instead -- check your local rules).
5 days at 9 hours each = 45 total hours: 40 regular + 5 overtime hours at the standard 40-hour threshold.
To convert the resulting overtime hours into actual dollar pay, see the Paycheck & Finance category's Paycheck & Salary Calculators. For a payroll-style weekly total with an hourly rate built in, use the Timesheet Calculator.
Enter the hours worked for each day, using decimal hours, and set the weekly overtime threshold. The tool adds the days into a weekly total, then reports regular hours (up to the threshold), overtime hours (anything above), and the number of days on which you worked. If a day was off, leave it at zero. Convert minutes to decimals first: 7 hours 30 minutes is 7.5, and 6 hours 45 minutes is 6.75.
A hypothetical week: Monday 8.5, Tuesday 9, Wednesday 7.75, Thursday 10, Friday 6.5, Saturday 4. The total is 45.75 hours. At the default threshold of 40, that is 40 regular hours and 5.75 overtime hours, over six worked days. Changing the threshold to 44 for a workplace with a different rule would give 44 regular and 1.75 overtime. Trying a few thresholds is a quick way to see how sensitive the split is to your employer's or contract's rule.
This tool applies a single weekly threshold to the total only. It does not apply daily overtime, double-time bands, or rules about consecutive days, all of which exist in some places and in some union or employment agreements. In such a case the true overtime can be higher than what this tool shows, because time counted as overtime on a long day may not be offset by a short day later in the week. Confirm the rules that apply to you with your employer, your state or national labor agency, or the US Department of Labor if you are in the United States.
Once you have the hours, the pay depends on your regular rate and the overtime multiplier your employer or jurisdiction requires. Use a paycheck or overtime pay calculator for dollars, and remember that exemption from overtime depends on your job duties and pay arrangement, which a calculator cannot determine.
Not everywhere -- some jurisdictions or union contracts calculate overtime on a daily basis (e.g. anything over 8 hours in a day) instead of weekly. This tool uses the weekly-threshold model; check your local labor rules for the applicable method.
Yes -- the default is 40 hours/week (the standard US FLSA threshold), but you can set any threshold your employer or jurisdiction uses.
No -- this splits hours only. Pair the resulting overtime-hours figure with your hourly rate and overtime multiplier separately, or use a dedicated overtime pay calculator.
40 hours per week, which you can change to match your employer, contract, or jurisdiction.
No. It uses a single weekly threshold on the total hours. If daily overtime applies to you, your actual overtime may be higher.
Use decimals. For example, 7 hours 30 minutes is 7.5 and 6 hours 45 minutes is 6.75.
