Day-Rate Overtime Calculator: How Daily Pay Converts to Overtime
Quick answer: Add the day-rate payments earned during the workweek, divide by total hours worked, and pay an additional one-half of that regular rate for each hour over 40 when the day rate already covers straight time.
How day-rate pay works
A day rate pays a fixed amount for each day worked, regardless of the number of hours in that day. This method is common in construction, oil and gas, event work, transportation support, staffing, and day labor.
The employee remains entitled to all compensable time. A day-rate employer must record hours and ensure both minimum wage and overtime compliance.
Day-rate overtime example
An employee earns $240 per day, works five days, and records 50 hours.
- Weekly day-rate earnings: 5 × $240 = $1,200
- Regular rate: $1,200 ÷ 50 = $24
- Overtime hours: 10
- Additional half-time premium: $24 × 0.5 × 10 = $120
- Total weekly pay: $1,320
Why the day rate does not include overtime
A flat payment does not qualify as an overtime premium merely because the amount seems high. Federal overtime premiums generally must be tied to the actual overtime hours and regular rate.
An agreement stating that a day rate “includes all overtime” is usually insufficient when it does not produce the legally required premium for each workweek.
Day rates plus bonuses and expenses
Nondiscretionary bonuses, shift premiums, and other compensation may increase the regular rate. Genuine reimbursements for reasonably approximate business expenses may be excluded when legal conditions are met.
Mislabeling wages as per diem, travel reimbursement, or tool allowance can understate the regular rate.
Long daily shifts and state law
Federal law generally triggers overtime after 40 weekly hours, but states such as California, Colorado, Nevada, and Alaska may require daily overtime under their own rules. A worker can therefore earn state overtime before exceeding 40 hours.
The payroll system must calculate both applicable standards without paying the same hour twice unless state law requires additional premiums.
Records to keep
- Each day worked and day-rate amount
- Actual start and stop times
- Meal periods and travel between job sites
- Bonuses, differentials, and reimbursements
- Workweek start and end dates
- State and project location
Frequently Asked Questions
Are day-rate employees exempt from overtime?
No. Payment by the day does not itself create an exemption.
What divisor is used for a day rate?
The total includable weekly pay is generally divided by the total hours actually worked.
Is half-time or time-and-one-half added?
When the day rate already covers straight time for all hours, an additional half-time premium is generally added for overtime hours.
Can a contract say the day rate includes overtime?
A label is not enough. The payment arrangement must satisfy federal and state overtime requirements.
Does daily overtime law also apply?
It can. State law may require overtime based on daily hours.
