Does this include child care tax credits or Dependent Care FSA?

Not directly. Apply those separately to improve the net working cashflow if you’re eligible. They can materially change the result.

Should I use marginal or effective tax rate?

Use a realistic effective rate for this earner’s income slice. Marginal rates can overstate taxes, while too-low rates can overstate net benefit.

What about benefits and career growth?

This tool is cashflow-only. Add the value of benefits (health insurance, retirement match) and long-term career impacts separately when deciding.

Does it handle part-time or hybrid work?

Yes—enter part-time income and reduced work costs/childcare as applicable. Adjust commute costs for hybrid schedules.

Can I model multiple kids or layered childcare (aftercare + camps)?

Yes—sum all annual childcare/aftercare/camp costs into the childcare input for a realistic total. Adjust work costs for seasonal changes if needed.

How do I include dependent care FSA or employer subsidies?

Reduce your childcare input by the expected FSA/subsidy benefit, or add the benefit back to net working in your own math. This calculator leaves credits/FSAs separate to keep assumptions explicit.

Should I count health insurance or retirement matches?

Those benefits are not included here. Add their dollar value to the net working result to get a fuller picture of the value of staying employed.

Childcare vs Stay-Home Breakeven

Compare keeping a second income after childcare and work costs versus staying home.

Results

After-tax income: $42,900
Net after childcare & work costs: $21,900
Childcare breakeven spend: $39,900
Cashflow verdict: working nets more

How to use this calculator

Enter the secondary earner’s gross income.
Enter an effective tax rate (use a conservative blended rate; do not overstate).
Add annual childcare costs plus commuting/meal/work expenses tied to working.
Review take-home, net after costs, and the breakeven childcare spend.
Adjust childcare or work costs to see where working turns cashflow-neutral or positive.

Inputs explained

Secondary earner gross income: Annual gross income for the second earner before taxes and deductions.
Effective tax rate (%): Blended federal/state/local rate on this income slice; use a realistic average.
Annual childcare costs: Total yearly childcare spend (daycare, nanny, aftercare, sitters for work hours).
Annual work/commute costs: Transportation, parking, meals out, uniforms, and other work-only expenses.

How it works

Take-home pay = income × (1 − effective tax rate).

Net working cash flow subtracts childcare and work/commute costs from take-home.

Breakeven childcare shows the max childcare spend before working nets $0.

Formula

Take-home = gross × (1 − effective tax rate). Net working = take-home − childcare costs − work costs. Breakeven childcare = take-home − work costs (the max childcare spend before net goes negative).

When to use it

Comparing immediate cashflow between keeping a second income vs. pausing work.
Testing how a change in childcare arrangement (nanny vs daycare) affects net cash.
Planning for a new child and estimating the impact on household cashflow.
Evaluating whether part-time or flexible work reduces costs enough to stay positive.
Checking how much a raise or bonus shifts the breakeven by boosting take-home.
Estimating the impact of dropping commute days in a hybrid schedule on net working cashflow.

Tips & cautions

Use a conservative effective tax rate; marginal rates can overstate taxes on this income slice.
Include the value of benefits (health insurance, 401k match) separately in your decision; this calculator is cashflow-focused.
Account for dependent care FSA and child care tax credits separately—those improve net working outcomes.
If commute costs vary (e.g., hybrid schedule), average them for the year.
Revisit after major changes: new child, rate changes, or switching childcare types.
If one parent’s income affects eligibility for credits or benefits cliffs, model those impacts separately so you don’t over/understate net cash.
Consider long-term effects: time out of the workforce can reduce future raises, Social Security credits, and equity comp accrual.
If childcare is seasonal (school year vs summer camps), annualize all costs so the net view isn’t distorted by part-year expenses.
Include any employer childcare subsidies or flex credits; subtract them from childcare costs for accuracy.
Effective tax rate is an estimate; does not include credits (e.g., child care tax credit).
Ignores retirement/benefit impacts and long-term career effects (raises, equity, Social Security credits).
Does not model joint taxes or cliff effects from credits/phaseouts.
Cashflow-only view; does not replace a full household budget or long-term career planning.

Worked examples

Net positive with moderate childcare

Income: $60,000. Effective tax rate: 20%. Take-home ≈ $48,000.
Childcare: $18,000. Work costs: $3,000. Net working = $48,000 − $18,000 − $3,000 = $27,000.
Breakeven childcare = $48,000 − $3,000 = $45,000. Current setup is solidly positive.

Near breakeven with higher costs

Income: $50,000. Effective tax: 22% → take-home $39,000.
Childcare: $20,000. Work costs: $4,000. Net working = $39,000 − $24,000 = $15,000.
Breakeven childcare = $39,000 − $4,000 = $35,000. Cashflow is positive but thinner; credits/FSAs could improve it.

Negative cashflow scenario

Income: $40,000. Effective tax: 18% → take-home $32,800.
Childcare: $24,000. Work costs: $5,000. Net working = $32,800 − $29,000 = $3,800.
Breakeven childcare = $32,800 − $5,000 = $27,800. Limited margin; credits/benefits could change the picture.

Hybrid schedule reduces work costs

Income: $55,000. Effective tax: 20% → take-home $44,000.
Childcare: $18,000. Work costs drop from $4,000 to $2,000 with hybrid commuting.
Net working = $44,000 − $20,000 = $24,000. Breakeven childcare = $42,000; hybrid schedule improves net by $2,000.

Applying dependent care benefits

Income: $70,000. Effective tax: 22% → take-home $54,600.
Childcare: $24,000, but $5,000 covered via Dependent Care FSA → $19,000 net childcare. Work costs: $3,000.
Net working = $54,600 − $22,000 = $32,600. Breakeven childcare = $51,600.

Deep dive

Use this childcare vs stay-home breakeven calculator to see how much of a second income remains after taxes, childcare, and commuting costs.

Enter income, effective tax rate, childcare, and work costs to find your net working cashflow and the childcare spend that would wipe it out.

Stress test scenarios by adjusting childcare type (nanny vs daycare), hybrid commute costs, and tax rates to see when working stays positive.

Layer in tax credits or dependent care FSA benefits separately to improve net cashflow; rerun after big life changes or new children.

Combine this with a benefits/career assessment to weigh long-term impacts beyond immediate cashflow.

If you’re considering a partial return or flexible schedule, adjust inputs to part-time income and reduced commute/childcare to see if it swings cashflow positive.

Use conservative tax/CPP assumptions to avoid overestimating take-home; revisit after raises, bonuses, or childcare changes.

Map seasonal costs like summer camps and aftercare into your annual childcare input to avoid underestimating expenses.

If you expect future raises, equity vesting, or bonuses, rerun the model to see how higher income shifts the breakeven.

If one partner carries health insurance for the household, factor that benefit and potential COBRA/ACA costs into your separate net calculation.

This calculator is a cashflow lens—pair it with a long-term career/benefits view (retirement, Social Security credits, skill growth) before deciding.

Budget a buffer for unexpected childcare closures or backup care; annualize those costs so the net view remains realistic.
