What this calculator helps you decide
Best for
Comparing two workweeks using pay, committed time and direct commute costs.
Outputs
Annual hours saved, commute cost saved, pay difference and adjusted hourly-value difference.
Start here
Enter pay, weekly hours, workdays and commute assumptions for both schedules.
- Close-intent boundary
- Do not use this to value leave days alone; use Paid Time Off Value Calculator, and enter actual hours because four days does not guarantee fewer weekly hours.

Four-Day Workweek: annual hours saved
Use the schedule comparison with time, commute and pay differences kept separate.
Formula summary
- Primary formula
- annualHoursSaved = currentCommittedHours − proposedCommittedHours
Data used here
- The estimate uses your inputs and the work-value formula documented in the methodology.
Decision checks
Act on the result
Confirm whether proposed hours are reduced or compressed into fewer days.
Stress-test the decision
Retest proposed weekly hours and commute assumptions for realistic variations.
When this estimate can be misleading
- A four-day schedule may redistribute rather than reduce hours.
- Work intensity and flexibility are not valued.
- Commute conditions can vary.
- Use the schedule comparison with time, commute and pay differences kept separate.

What should stay consistent when I compare the options?
Keep the time basis, units and included costs consistent across options, then verify the assumptions that create the largest difference.
