How to use this result
Reducing hours changes more than wages. Fewer childcare days and commutes may soften the income drop, while losing an employer benefit can make it larger.
Use the same annual weeks for this comparison. If the jobs have different paid-week patterns, the job-offer calculator provides a more flexible comparison. Reported time freed covers paid hours only.
The formula
Worked example
Using the example inputs loaded above:
$28,724.00
Annual value given up by moving part time.
Common questions
Can the part-time result be higher?
Yes. A higher hourly rate or lower costs can offset reduced hours. A negative highlighted difference means part-time has higher modeled annual value.
Will this tell me if I keep health insurance?
No. Confirm eligibility and replacement costs with the employer before entering the benefits values.
