Return to Work Payback: monthly net gain
Use monthly net gain and payback together; no positive monthly gain means no payback.
Formula summary
- Primary formula
- monthlyNetGain = monthlyNetPay − monthlyChildcare − monthlyCommute − monthlyOtherRecurring

Retest childcare and monthly net pay.
When this estimate can be misleading
- No tax, subsidy, eligibility or childcare-policy calculation is performed.
- Non-financial benefits and constraints are excluded.
