Childcare Cost vs. Working Income: How to Calculate Whether Going Back to Work Pays

Your second child is due in October. Infant daycare in your area costs $1,650 per month. Your take-home pay after taxes, health insurance, and retirement contributions is $4,200 per month. Subtract daycare and you are left with $2,550. That is still positive, so working pays. But what about the commute, the work wardrobe, the lunches out, and the extra hours of care you will need for your older child? The math is more complex than subtracting daycare from salary. Childcare cost versus working income is a calculation that needs after-tax figures, hidden costs, and the time value of the income you keep. Use our Childcare Cost vs. Working Calculator to run the numbers with 2026 state-specific daycare rates and your actual tax situation.

What Is the Childcare Cost vs. Working Calculation?

The childcare cost versus working calculation compares the net income a parent retains after paying for childcare against the value of staying home. It is not simply salary minus daycare. The calculation accounts for taxes, because additional income is taxed at your marginal rate, not your average rate. It also accounts for work-related expenses that disappear if you stop working: commuting, professional clothing, meals, and before-school or after-school care for older children.

The result tells you how much money you actually keep from working after all child-related and work-related costs are subtracted. If the number is positive, working generates net income for the household. If the number is near zero or negative, the financial case for working weakens, though non-financial factors like career progression, retirement contributions, and Social Security credits may still justify the decision.

The Childcare Cost vs. Working Formula

Net Benefit of Working = After-Tax Working Income - Childcare Costs - Work-Related Expenses

After-tax working income is your gross salary minus federal income tax, state income tax, FICA, and any benefit deductions (health insurance, retirement). Childcare costs include all care expenses for children while you work. Work-related expenses include commuting, parking, professional clothing, meals purchased at work, and any additional care needed for other children because of your work schedule.

A more precise version separates marginal from average effects:

Marginal Net Benefit = (Additional Gross Income × (1 - Marginal Tax Rate)) - Childcare - Work Expenses

The marginal tax rate matters because the second income is taxed on top of the first. A family with a primary earner at $95,000 and a second earner at $65,000 may face a marginal federal rate of 22 percent plus state tax on the second income. The second earner's $65,000 gross may shrink to $44,000 after all taxes and deductions.

Step-by-Step Example: Two-Parent Family with Infant and Preschooler

A family in suburban Chicago has two children. One is an infant (10 months) and the other is preschool age (3.5 years). The mother is deciding whether to return to work after 12 weeks of parental leave.

Her salary would be $72,000 per year, or $6,000 per month gross.

Step 1: Calculate after-tax income.

The husband earns $88,000. Filing jointly in Illinois, the family's marginal federal tax bracket is 22 percent. Illinois state tax is 4.95 percent flat. FICA is 7.65 percent. Her marginal tax rate is approximately 34.6 percent.

After-tax monthly income = $6,000 × (1 - 0.346) = $3,924

Step 2: Calculate childcare costs.

Using 2026 Illinois averages from HHS market rate survey data:

• Infant center care: $1,425/month
• Preschool center care: $1,050/month (she would need full-time since she works)
• Total childcare: $2,475/month

Step 3: Calculate work-related expenses.

• Commuting (gas, parking, tolls): $185/month
• Work lunches and coffee: $120/month
• Professional clothing: $75/month (amortized)
• Total work expenses: $380/month

Step 4: Calculate net benefit.

Net benefit = $3,924 - $2,475 - $380 = $1,069/month

Working generates $1,069 per month, or $12,828 per year, after all child and work-related costs. That is positive, but it represents only 18 percent of her gross salary. The family needs to decide whether $12,828 per year justifies the time away from home and the logistics of dual-career childcare.

What Do the Numbers Mean?

Childcare costs in 2026 have reached a national average of $1,230 per month for infant center-based care, up 5 percent from $1,171 in 2025. The cost varies dramatically by state and by child age:

The Department of Labor reports that in most US counties, childcare costs for two children exceed the cost of a mortgage. For a family in Massachusetts paying $2,100 per month for infant care and $1,650 for preschool, total childcare runs $3,750 monthly. A parent earning $75,000 gross, or about $4,050 per month after taxes in Massachusetts, would net only $300 per month after childcare alone, before work expenses.

The break-even income, the salary at which working covers childcare and nothing more, varies by state:

Break-even gross salary assumes a marginal tax rate of approximately 35 percent including federal, state, and FICA. A parent earning below the break-even in their state would lose money by working, before considering career advancement and benefits.

Real-World Example: Single Parent in Atlanta

A single mother in Atlanta, Georgia earns $52,000 per year as a marketing coordinator. She has one infant (8 months) who needs full-time center-based care.

Georgia infant center care averages $850 per month, or $10,200 per year.

Her after-tax income: Filing as head of household, her marginal federal rate is 22 percent, Georgia state tax is 5.39 percent, and FICA is 7.65 percent. Her marginal rate is approximately 35 percent.

After-tax monthly income = $52,000 / 12 × (1 - 0.35) = $2,817

Net benefit = $2,817 - $850 - $280 (work expenses) = $1,687/month

Working generates $1,687 per month, or $20,244 per year. That is a clear positive. But she also qualifies for the federal Child and Dependent Care Tax Credit, which covers up to 35 percent of $3,000 in qualifying expenses for one child, or up to $1,050. This credit reduces her tax liability at year-end, effectively lowering her net childcare cost to $766 per month. The adjusted net benefit becomes $1,771 per month.

She also enrolls in her employer's dependent care FSA, contributing $5,000 pre-tax. This saves her approximately $1,225 in taxes at her marginal rate. Combined with the tax credit, her effective childcare cost drops to approximately $640 per month, and her net benefit from working rises to $1,897 per month.

The tax benefits matter. A family that ignores the Child and Dependent Care Credit and the FSA may conclude that working barely pays, when the after-tax calculation shows a comfortable margin.

Common Mistakes to Avoid

Using gross salary instead of after-tax income. The most common error is comparing gross salary to childcare costs. A $60,000 salary is not $5,000 per month in your pocket. After federal tax, state tax, FICA, and benefit deductions, it may be $3,400. Always use after-tax figures.

Forgetting the Child and Dependent Care Tax Credit. This federal credit covers 20 to 35 percent of up to $3,000 in care expenses for one child or $6,000 for two or more children. The percentage depends on your adjusted gross income. Many families overlook this credit, which can reduce effective childcare costs by $600 to $2,100 per year.

Ignoring the dependent care FSA. If your employer offers a dependent care FSA, you can contribute up to $5,000 pre-tax. This reduces your taxable income and saves you money at your marginal tax rate. For a family in the 22 percent federal bracket with 5 percent state tax, the FSA saves approximately $1,350 per year.

Counting only daycare, not the full cost of working. Commuting, parking, work clothing, lunches, and additional care for older children during school breaks all reduce the net benefit of working. A parent who spends $300 per month on work-related expenses on top of $1,800 in daycare has $2,100 in total costs, not $1,800.

Assuming the calculation is permanent. Childcare costs drop as children age. Infant care at $1,230 per month becomes preschool care at $920 per month, then after-school care at $770 per month. A parent who barely breaks even during the infant years may see a comfortable margin by age three. Run the calculation for each year from birth through kindergarten to see the full picture.

Frequently Asked Questions

How much does infant daycare cost in 2026?

The national average for full-time infant center-based care is $1,230 per month, or $14,760 per year. Costs range from $650 per month in Mississippi to $2,400 per month in Washington DC. Home-based daycare providers average 20 to 30 percent less than center-based care at every age. The cost is highest for infants because state regulations require lower caregiver-to-child ratios, typically 1:3 or 1:4.

At what salary does it stop being worth it to work and pay for childcare?

The break-even salary depends on your state, number of children, and tax situation. For one infant in center-based care, the break-even gross salary is approximately $21,000 in Mississippi, $36,000 in Texas, $45,000 in Illinois, and $68,000 in Massachusetts. Below these levels, childcare costs may exceed the after-tax income from working. However, non-financial factors like career growth, retirement savings, and health insurance benefits may still justify working below the break-even point.

Does the Child and Dependent Care Tax Credit help?

Yes. The federal credit covers 20 to 35 percent of up to $3,000 in qualifying childcare expenses for one child, or $6,000 for two or more children. Families with adjusted gross income below $15,000 qualify for the 35 percent rate. The rate phases down to 20 percent for incomes above $43,000. A family with $43,000 in AGI and $6,000 in childcare expenses for two children receives a $1,200 credit. This is a tax credit, not a deduction, so it reduces your tax bill dollar for dollar.

How much does a family spend on childcare from birth to kindergarten?

At 2026 national average rates, a family with one child in center-based care from birth through age five spends approximately $62,760 total. The first year (infant) costs $14,760, years two and three (toddler) cost $12,960 each, and years four and five (preschool) cost $11,040 each. Costs are higher in expensive states and lower with home-based care or family help.

Should I consider a nanny instead of daycare?

A nanny averages $2,700 per month nationally in 2026, not counting employer payroll taxes. For one child, center-based daycare at $1,230 per month is cheaper. For two or more children, a nanny may be cost-competitive. Two children in center-based infant and toddler care could cost $2,310 per month combined, while a nanny for both costs $2,700 plus payroll taxes. The nanny also eliminates your commute time and provides in-home convenience. Run both scenarios through the calculator to compare.

Conclusion

The childcare cost versus working calculation is not a single number. It changes with your child's age, your tax bracket, your state's daycare rates, and the tax credits and FSA contributions you claim. A parent who barely breaks even during the infant year may see a comfortable margin by preschool. The calculation also extends beyond money: career progression, retirement account growth, and Social Security credits accumulate even when the monthly net benefit is small. Run the numbers for each year from birth through kindergarten, include the tax credits, and decide with full information. Ready to calculate? The Childcare Cost vs. Working Calculator uses 2026 state rates and your tax situation to show the net benefit of working.
