Overtime Calculator
Find out exactly what time you'll hit daily or weekly overtime, based on when you clocked in and how many hours you've already worked this week.
When Does Overtime Start?
Overtime rules depend on where you work, but two thresholds come up most often:
- Weekly overtime: Under federal law (the Fair Labor Standards Act), most hourly employees earn overtime pay after working 40 hours in a single workweek.
- Daily overtime: Some states — California is the best-known example — also require overtime pay after 8 hours in a single day, even if you haven't hit 40 hours yet for the week.
This calculator is for general reference only and isn't legal advice — always check your state's labor laws and your employer's specific policy.

Overtime Reference Chart (Daily 8-Hour Threshold)
Quick reference: if your state requires daily overtime after 8 hours, here's when that threshold hits based on your start time.

Federal vs. State Overtime Rules
The federal 40-hour weekly threshold applies nationwide to most non-exempt hourly employees. Daily overtime thresholds, on the other hand, are set at the state level and only apply in certain states. If you're not sure which rules apply to you, your state's Department of Labor website or your employer's HR department can confirm.
How Overtime Pay Usually Works
When you qualify for overtime, it's typically paid at 1.5 times your regular hourly rate ("time and a half") for qualifying hours. Some employers or union agreements pay higher rates for holidays or extended hours, so it's worth checking your specific pay policy.
Who This Calculator Helps
This tool is useful for hourly employees who want a heads-up before they accidentally cross into overtime, as well as managers and schedulers trying to plan shifts without triggering unplanned overtime costs.
