How the Overtime Calculator Works
Regular Pay
Your base hourly rate multiplied by your standard hours (usually 40 per week). This is the foundation of every overtime calculation.
Overtime Pay
Hours beyond 40 per week multiplied by your overtime rate. The FLSA mandates at least 1.5x your regular rate for non-exempt workers.
Effective Rate
Your total pay divided by total hours worked. Working overtime raises your effective hourly rate above your base rate.
FLSA Overtime Rules and State Differences
The Fair Labor Standards Act (FLSA) is the federal law that governs overtime pay in the United States. Under the FLSA, non-exempt employees must receive at least 1.5 times their regular hourly rate for every hour worked beyond 40 in a single workweek. This overtime calculator applies that standard automatically.
State Overtime Rules Comparison
| State | Daily OT | Double Time |
|---|---|---|
| California | After 8 hrs/day | After 12 hrs/day |
| Colorado | After 12 hrs/day | No |
| Alaska | After 8 hrs/day | No |
| Nevada | After 8 hrs/day | No |
| Texas | Federal only | No |
| New York | Federal only | No |
Most states follow the federal 40-hour weekly rule. California, Alaska, Colorado, and Nevada also have daily overtime triggers.
Overtime Calculator Example
An employee earning $25/hr works 50 hours in one week (40 regular + 10 overtime at 1.5x). Regular pay: 40 x $25 = $1,000. Overtime pay: 10 x $37.50 = $375. Total gross pay: $1,375. Their effective hourly rate for the week is $27.50/hr — a 10% bump over their base rate from working just 10 extra hours.
