How to Calculate Overtime Pay Correctly
Overtime pay is one of the easiest payroll lines to get wrong, and the mistakes add up fast. This guide explains how to calculate overtime pay correctly, including the overtime rate, the hours that count toward overtime, and the steps to keep every overtime paycheck accurate and compliant.
Overtime pay is one of the easiest payroll lines to get wrong, and the mistakes add up fast. When the overtime rate is off or the overtime hours are miscounted, a paycheck comes out wrong and the error can repeat every pay period until someone catches it. Getting overtime right keeps your team paid correctly and your records clean.
This guide explains how to calculate overtime pay correctly, including the overtime rate, the hours that count toward overtime, and the steps to keep every overtime paycheck accurate. If you are newer to payroll altogether, it helps to start with our guide on payroll processing basics before you dig into the overtime math.
What Is Overtime Pay?
Overtime pay is the extra pay an employee earns for hours worked beyond the standard threshold in a work period. It is part of gross pay, which means it sits on the paycheck before any withholdings or deductions come out. Overtime is calculated separately from regular pay, then added to it to arrive at total gross pay for the period.
The reason overtime is calculated separately is that it uses a different rate. Regular hours use the regular rate, and overtime hours use the overtime rate. Keeping the two calculations separate is what keeps overtime accurate. For a closer look at how overtime fits into the larger gross pay number, see our guide on how to calculate employee gross pay.
The Overtime Rate
The overtime rate is the pay rate applied to overtime hours. For many employees, the overtime rate is one and a half times the regular hourly rate, often called time and a half. The exact rate can depend on the employee, the work, and the rules that apply where the employee works, so the first step is always to confirm the rate that applies before you run payroll.
| Pay type | Rate | Applies to |
|---|---|---|
| Regular pay | Regular hourly rate | Hours up to the threshold |
| Overtime pay | Often one and a half times the regular rate | Hours beyond the threshold |
When the overtime rate is one and a half times the regular rate, an employee earning $20 per hour has an overtime rate of $30 per hour. The overtime rate is always tied to the regular rate, so a wrong regular rate makes the overtime rate wrong too. Double check the regular rate before you calculate the overtime rate.
Which Hours Count Toward Overtime
The hours that count toward overtime are the hours worked beyond the standard threshold in the work period. The threshold is often set by the workweek, but the exact threshold and how the workweek is defined can depend on the rules that apply where the employee works. Track every hour worked so you can identify the overtime hours accurately.
Only hours actually worked count toward overtime. Paid time off, holidays, and other leave generally do not count as hours worked, even though they may be paid. That distinction matters because adding paid leave hours to worked hours is a common way to overcount overtime. Keep worked hours and paid leave tracked separately so the overtime hours stay accurate. For more on how the schedule that holds these hours comes together, see our guide on how to create a reliable payroll schedule.
Quick tip. Track worked hours and paid leave in separate columns on every timesheet. When the two are mixed, overtime hours get overcounted and the overtime pay comes out too high. Keeping them separate is the single biggest overtime accuracy win.
How to Calculate Overtime Pay
Calculating overtime pay comes down to a few clear steps. Follow them in order on every pay run that includes overtime, and the math stays clean.
- Confirm the overtime threshold and rate that apply where the employee works.
- Identify the regular hours up to the threshold and the overtime hours beyond it.
- Calculate regular pay by multiplying regular hours by the regular rate.
- Calculate overtime pay by multiplying overtime hours by the overtime rate.
- Add regular pay and overtime pay together to arrive at total gross pay for the period.
- Review the calculation before payroll so the overtime pay lands on the right paycheck.
The key is to keep regular pay and overtime pay as two separate calculations and add them at the end. Adding overtime hours to regular hours and multiplying by the regular rate is the most common overtime mistake, and it underpays the employee every time. For a closer look at how those lines fit together on a paycheck, see our guide on how payroll deductions work.
Example: A Retail Employee's Overtime
Consider a small retail shop with an hourly employee paid $18 per hour on a weekly pay schedule. In a week where the employee works 40 regular hours, their regular gross pay is $720, which is 40 hours times $18. No overtime applies, so total gross pay for the week is $720 before withholdings.
In another week, the same employee works 46 hours. Six of those hours are counted as overtime. Regular gross pay is still $720 for 40 regular hours. If the overtime rate is one and a half times the regular rate, the overtime rate is $27 per hour, and 6 overtime hours add $162 of overtime pay. Total gross pay for that week is $882. The example shows how keeping regular and overtime hours separate keeps the overtime pay accurate.
Example: A Warehouse Employee's Overtime
Take a small warehouse with an hourly employee paid $22 per hour on a weekly pay schedule. In a busy week, the employee works 50 hours, with 10 of those hours counted as overtime. Regular gross pay is $880 for 40 regular hours. If the overtime rate is one and a half times the regular rate, the overtime rate is $33 per hour, and 10 overtime hours add $330 of overtime pay. Total gross pay for the week is $1,210 before withholdings.
If the employee had taken 8 hours of paid time off that same week, those 8 hours would be paid but would not count as hours worked. The overtime hours would still be based on the 50 hours actually worked, not on 58. The example shows why keeping worked hours and paid leave separate matters for overtime accuracy.
Common Overtime Calculation Mistakes
- Adding overtime hours to regular hours before multiplying. Overtime hours use the overtime rate, not the regular rate. Adding them to regular hours and multiplying by the regular rate underpays overtime every time. Keep the two calculations separate and add the results.
- Counting paid leave as hours worked. Paid time off, holidays, and other leave are paid but generally do not count as hours worked. Adding them to worked hours overcounts overtime. Track worked hours and paid leave separately.
- Using the wrong overtime rate. The overtime rate is tied to the regular rate, and the exact multiple can depend on the rules that apply where the employee works. Confirm the rate that applies before you run payroll so the overtime pay is right.
- Not tracking hours by the right work period. Overtime is often based on the workweek, and how the workweek is defined can depend on the rules that apply. Track hours by the correct work period so the overtime threshold is applied accurately.
- Assuming salaried employees never get overtime. Exemption is based on specific criteria, not on the fact that someone is paid a salary. Confirm whether an employee is exempt before you decide not to pay overtime.
- Not reviewing overtime before payroll. An overtime error repeats every pay period until someone catches it. Review the overtime calculations before payroll so the overtime pay lands on the right paycheck the first time.
