Overtime Pay Formula Explained
The calculator uses straightforward mathematical formulas to compute earnings.

Overtime Pay=Hourly Rate×Multiplier×Overtime Hours
3. Total Pay Formula
Total Pay=Regular Pay+Overtime Pay
Example Calculations
Example 1: Standard Overtime
- Hourly Rate: $20
- Regular Hours: 40
- Overtime Hours: 10
- Multiplier: 1.5
Step 1: Regular Pay
20 × 40 = $800
Step 2: Overtime Pay
20 × 1.5 × 10 = $300
Step 3: Total Pay
800 + 300 = $1100
Example 2: Double-Time Overtime
- Hourly Rate: $25
- Regular Hours: 35
- Overtime Hours: 8
- Multiplier: 2
Regular Pay: 25 × 35 = $875
Overtime Pay: 25 × 2 × 8 = $400
Total Pay: $1275
