You worked late nights or covered weekend shifts and need to know exactly how much gross overtime pay should be added to your next paycheck based on your hourly rate and statutory multipliers.
How to use Calculate Overtime Pay step by step
1. Enter baseline salary
Input your monthly salary and pick your country (Panama, Mexico, Colombia, Argentina, Chile or other) to use its divisor and surcharges.
2. Select standard weekly hours
Specify the contractual daily or weekly schedule (e.g., 8 daily hours in Panama or 42 a week in Colombia).
3. Input overtime hours logged
Enter the hours of each type (day, night, Sunday or holiday) and adjust the multiplier if your agreement pays differently.
The Step Count: Traditional Friction vs. KorexTools
Calculating overtime pay manually (5 steps)
- Divide monthly salary by monthly schedule divisor (e.g. 200 or 220 hours).
- Multiply base hourly wage by 1.5 for standard overtime shifts.
- Multiply base hourly wage by 2.0 for holiday/weekend double-time shifts.
- Multiply each rate by the hours completed in that bracket.
- Sum subtotals onto your base monthly earnings.
With KorexTools Overtime Pay Calculator (3 steps in 3 seconds)
- Enter base monthly pay and standard contracted weekly hours.
- Input the count of overtime hours logged at 1.5x and 2.0x tiers.
- Review your derived hourly rate and total gross overtime compensation.
Monetizing overtime shifts: deriving the baseline hourly rate
The regular hourly wage is derived by dividing monthly earnings by contractual hours. For instance, in a 40-hour weekly schedule, monthly average hours equal: (40 × 52 weeks) / 12 months = 173.33 hours. Regular Hourly Rate = Monthly Salary / 173.33.
Labor standards categorize overtime pay according to fatigue and shift timing: 1) Daytime overtime: standard 25% surcharge (1.25x regular rate); 2) Night shift overtime: 50% surcharge (1.50x time-and-a-half); and 3) Mandatory rest day or statutory holiday shifts: 100% surcharge (2.0x double time).
Common overtime multiplier tiers
- •Daytime overtime (1.25x): work extending beyond regular daylight scheduled hours.
- •Night shift overtime (1.50x): work performed during designated nocturnal windows (typically 6:00 PM to 6:00 AM).
- •Holiday / Rest day overtime (2.0x): work scheduled on statutory national holidays or mandatory weekly rest days.
Overtime earnings breakdown based on a $10.00 / hour baseline wage
| Surcharge Category | Multiplier | Rate per Overtime Hour | Payout for 5 Logged Hours |
|---|---|---|---|
| Daytime overtime (+25%) | 1.25× | $12.50 / hr | $62.50 |
| Night overtime (+50%) | 1.50× (Time & a half) | $15.00 / hr | $75.00 |
| Night holiday (+75%) | 1.75× | $17.50 / hr | $87.50 |
| Holiday / Rest day (+100%) | 2.00× (Double time) | $20.00 / hr | $100.00 |
Common Mistakes and How to Avoid Them
- ⚠️Dividing salary by 30 days and 8 hours (240 divisor) when contracted hours are lower.
- ⚠️Forgetting that regular overtime pay scales up holiday and severance entitlement calculations.
