Extra Work Hours & Effective Pay Calculator
See how extra working hours change salary per hour. Compare actual hours with a reference schedule.
This is time-and-pay arithmetic, not a burnout assessment or a calculation of legally owed overtime.
When to use this tool:
- Identify overwork impact
- Calculate true hourly value
- Decision support for scaling back
How it's Calculated
- Effective hourly rate = annual salary / (actual weekly hours × 52).
- Extra hours = max(0, actual weekly hours − reference weekly hours) × 52.
- Reference value of extra hours = extra hours × annual salary / (reference weekly hours × 52).
Key Assumptions
Defaults are example inputs. See methodology and corrections for how to check results, or report an issue.
- Salary stays fixed and the schedule repeats for 52 weeks.
- No health, productivity or legal entitlement model is used.
Actionable Insights
- At fixed pay, increasing from 40 to 50 hours reduces pay per hour by 20%.
- The reference value of extra hours is an opportunity-cost illustration, not additional wages owed.
Frequently Asked Questions
No. It measures hours and salary only.
No. Overtime entitlement depends on the job and applicable rules.
The weekly hours you want to compare with actual hours.
The model uses 52 repeated weeks. Use a representative average for a yearly comparison.
Use the commute calculator to keep travel time separate from working hours.
Use annual income and all hours worked for an effective-rate comparison; track business expenses separately.
Worked example: fixed salary, longer weeks
A $90,000 salary over 40 hours × 52 weeks is $43.27/hour. Over 50 hours × 52 weeks it is $34.62/hour. The extra 520 hours have a reference value of $22,500 at the original hourly rate. Your annual salary remains $90,000.
Use these figures to discuss workload and priorities. They do not quantify health effects, establish an overtime claim or imply that every extra hour could be sold at the reference rate.
