What this calculator helps you decide
Best for
Testing whether a second job clears entered deductions, direct costs and extra time.
Outputs
Annual net benefit, committed-hour value, break-even earnings and retained earnings rate.
Start here
Enter second-job earnings, your deduction estimate, direct costs and weekly hours.
- Close-intent boundary

Second Job Worth It: annual net benefit
Use net annual and hourly value together; neither is the same as gross second-job pay.
Formula summary
- Primary formula
- annualNetBenefit = annualEarnings − annualDeductions − annualDirectCosts
Data used here
- The estimate uses your inputs and the work-value formula documented in the methodology.
Decision checks

Stress-test the decision
Retest direct costs and work weeks.
