Weekly overtime calculator
Enter the hours you worked each day. Days off and half days come off your target automatically. Add your hourly rate to see your overtime pay.
How the calculation works
Your weekly target is your daily hours multiplied by your working days. A day off takes a full day out of the target and a half day takes half. With an 8-hour day, a week with a public holiday has a 32-hour target, not 40. Overtime is what you worked minus that target; a negative result is time you owe.
The on-track band is the one Clockflux uses: up to 12.5% over target (40 to 45 hours on a standard week) is treated as normal; beyond that, it’s overtime worth keeping an eye on. For the full method, with examples, see how to calculate overtime.
Tracking it week after week
One week is easy to add up by hand; a year of them is not. Clockflux records your hours as you go and keeps a running overtime balance across every week, so you always know where you stand. See overtime and work/life balance.
This calculator is a guide to your hours, not legal or payroll advice: how overtime is paid or compensated depends on your contract and local law.
Working out overtime pay
Overtime pay is your overtime hours × your hourly rate × the overtime rate. Time and a half (×1.5) is the most common premium and double time (×2) is often used for Sundays or public holidays, but some contracts pay overtime at the normal rate, or give the hours back as time off instead. On a salary, your hourly rate is your annual salary ÷ 52 ÷ your contracted weekly hours: £31,200 ÷ 52 ÷ 40 = £15 an hour, so 3.5 hours at time and a half is £78.75.
In the UK there is no legal right to overtime pay: your contract sets the rate, as long as your average pay for all the hours you work stays above the National Minimum Wage. In the US, the Fair Labor Standards Act requires at least time and a half for non-exempt employees’ hours over 40 in a workweek. Check your contract for the rate that applies to you.
