Overtime Pay Calculation: Complete Guide
Overtime pay rules decide how much extra you earn beyond your regular hours. Understanding the formulas—and your local rules—keeps you from leaving money on the table.
How Overtime Is Usually Calculated
The standard formula multiplies your hourly rate by a multiplier for each overtime hour. Many places require 1.5x for weekday overtime, 2x for rest days, and 3x for holidays. Your location's labor law defines the exact rates.
Know Your Base Hourly Rate
Divide your monthly salary by the number of working days and then by the daily hours to get your base hourly rate. Bonuses and allowances may or may not count toward the overtime base.
Tracking Your Hours
Keep your own log in addition to the company system. When discrepancies appear, a personal record is the fastest way to resolve them.
Budgeting the Extra Income
Overtime income is taxed like regular income and can push you into a higher bracket. Set aside the estimated tax portion before spending the rest.
Overtime and Labor Rights
Overtime rules are usually set by labor law, not by company preference. Know the maximum weekly hours and the required multipliers in your jurisdiction, and keep evidence of hours worked.
If an employer miscalculates overtime, raise it with written documentation first. If unresolved, official labor complaint channels exist in most regions.
How to Calculate Overtime Pay
- Enter your monthly salary and the standard working days and hours.
- Add the overtime hours and the applicable multiplier for the day type.
- Read the extra amount and check it against your payslip.
Calculate weekday, rest-day, and holiday overtime separately—they usually use different multipliers.
Quick tip: screenshot or export your attendance records monthly. If a dispute arises, contemporaneous evidence beats memory every time. Keep the records even when everything looks right, because patterns only show up over time.
