Is It Worth Working With Childcare Costs? Work vs. Stay-Home Calculator

How This Calculator Works

The useful question isn't what your salary is. It's how much better off your household is with your paycheck than without it. The calculator works out your household's 2026 federal taxes twice, once with your job and once without it, and then subtracts everything the job costs:

• Income tax on the added pay. If you're married filing jointly, your pay is stacked on top of your partner's, so it's taxed at your household's marginal rate instead of starting in the 10% bracket. The calculator uses the 2026 brackets and standard deduction ($32,200 for joint filers, $24,150 for heads of household).
• Credits that change with income. A second income can shrink the Earned Income Tax Credit (for a married couple with two children it phases out completely at $65,899 of income in 2026) and, at lower incomes, change how much of the $2,200-per-child Child Tax Credit the family can use.
• Payroll taxes. 6.2% Social Security on the first $184,500 of wages plus 1.45% Medicare, and the 0.9% Additional Medicare tax on wages above $250,000 for joint filers ($200,000 for single parents).
• State and local tax. A flat rate you enter, applied to your taxable pay.
• Childcare and its tax breaks. The Dependent Care FSA and the Child and Dependent Care Credit generally require both spouses to have earnings (a single parent just needs their own), so they count in working's favor. The calculator tests every FSA amount in $100 steps and keeps the split that saves the most.
• Work costs and retirement. Commuting and other job costs come off the top. Your 401(k) contributions and employer match are shown separately as retirement savings, because they add to your wealth but not to this month's budget.

Three Worked Examples

These come straight from the calculator above, so you can reproduce them. They show how differently the same question plays out at different incomes.

Example B is the trap the calculator is built to catch. If either employer in B offered a Dependent Care FSA, putting $7,500 through it would lift the childcare tax savings from $2,100 to $3,054, because the lower income restores part of the EITC, but working would still cost about $4,135 a year at those childcare prices. A family in that position should check child care subsidy eligibility and price cheaper care before deciding; the answer changes completely if a subsidy cuts the bill.

Childcare prices in the examples are our national averages: $1,438/mo for infant daycare, $1,174/mo for preschool daycare, and $2,028/mo for a toddler plus a preschooler in in-home daycare. Use the zip-code calculator for local prices.

Why the Childcare Tax Breaks Count Only If You Work

Both federal childcare tax breaks are tied to work. To claim the Child and Dependent Care Credit or exclude Dependent Care FSA money from income, the care has to let you (and your spouse, if you're married) work or look for work, and the amount can't exceed the lower earner's earned income. A spouse who is a full-time student or disabled is treated as having earnings. So when one parent stays home, the family usually gives up both breaks along with the childcare bill.

For 2026, P.L. 119-21 raised the FSA limit to $7,500 per household ($3,750 if married filing separately) and raised the credit rate for most families. The credit is 50% at adjusted gross income of $15,000 or less, 35% from $43,001 up to $150,000 for joint filers ($75,000 for others), and steps down to a 20% floor above that. It applies to up to $3,000 of care for one child or $6,000 for two or more, minus any FSA money, so a maxed-out FSA leaves no room for the credit. Which one wins depends on your bracket, and the calculator tests both. For a closer look, use the Dependent Care FSA calculator or the child care tax credit calculator, or read DCFSA vs. the child care credit.

One more catch: the credit is nonrefundable. It can only cancel federal income tax you owe, and it's applied before the Child Tax Credit. Families whose income tax is already wiped out by the standard deduction and the Child Tax Credit may get little or nothing from it. The calculator applies that limit, which is why its credit can be lower than a simple percentage-of-expenses estimate.

Long-Term Factors the Monthly Math Misses

The calculator measures one year of cash flow. Several things that matter over a decade don't fit in that number, and most of them favor staying attached to work, even at a small monthly gain:

• Earnings growth. Raises, promotions and job changes build on whatever you're earning when you return. Time away can slow that progress, and in fields with licenses or fast-changing tools, skills and credentials need upkeep. How much a gap costs varies widely by field, so ask people in your industry who have stepped away and come back.
• Retirement savings. Your 401(k) contributions and employer match stop when the paycheck stops, and early contributions have the longest time to compound. When you enter 401(k) figures, the results above show what one year of contributions could grow to. A spouse without earnings can still save through a spousal IRA if the couple files jointly and the working spouse's earnings cover the contributions.
• Social Security. You need 40 credits, about 10 years of work, to qualify for retirement benefits on your own record. In 2026 you earn one credit for each $1,890 of earnings, up to four a year. Your benefit is based on your highest 35 years of indexed earnings, and if you have fewer than 35 years, the missing years count as zeros. A spouse with a thin record may get a spousal benefit of up to 50% of the partner's full-retirement-age benefit, which generally requires being married at least a year (or at least 10 years, if divorced).
• Disability and survivor protection. Social Security disability coverage depends on recent work: generally 40 credits, 20 of them earned in the 10 years before the disability, with fewer required for younger workers. Survivors benefits for your children can be paid with as few as six credits earned in the three years before death.
• Health insurance and other benefits. If your job carries the family's health plan, price the replacement before deciding and enter the extra monthly cost in the "job benefits you'd lose" box.
• The cost is temporary. Childcare costs the most in the infant years. Our national daycare averages fall from about $1,438 a month for an infant to $1,335 for a toddler, $1,174 for a preschooler and $667 for before- and after-school care. A job that barely breaks even with a baby may pay noticeably better in two or three years, so re-run the calculator with your child's next age group.

Hidden Costs on Both Sides

Put your own numbers on these from bank and card statements rather than rules of thumb.

Costs of working

• Commuting: fuel, parking, tolls, transit and wear on the car. For driving, multiply your monthly commute miles by your full per-mile cost (fuel plus maintenance and depreciation), not fuel alone.
• Clothes, lunches and coffee that you buy because you're at work.
• Convenience spending: more takeout, grocery delivery or paid cleaning when both parents work.
• Sick days: daycares send children home with fevers and other symptoms, so someone takes time off or you pay for backup care.
• Gaps in coverage: summer weeks, school holidays and early-release days once children reach school age.

Costs of staying home

• Lost retirement contributions and employer match.
• A slower return to work after a gap, which depends heavily on your field.
• Fewer Social Security credits and possible zero years in your benefit calculation.
• Replacing employer health insurance or other benefits, if your job provides them.
• More risk on one income: a layoff, disability, divorce or death of the earning partner hits harder, which makes life and disability insurance on that partner more important.

If the Numbers Are Close

• Price other kinds of care. Our national averages put in-home (family) daycare at about $1,141 a month for an infant, versus $1,438 at a center. Compare options on our in-home daycare page. With two or more young children, a nanny share can cost less per family than separate daycare spots.
• Check for help paying. States run child care subsidy programs funded by the federal Child Care and Development Fund. Federal rules let states serve families earning up to 85% of state median income, though many set lower limits and some have waiting lists. Start with our subsidy eligibility calculator and guide to finding subsidies.
• Use your employer's benefits fully. Enroll in the Dependent Care FSA at open enrollment. Many plans also allow a mid-year change after a qualifying event such as a birth or adoption, or a change in your childcare provider or cost. Ask about backup care and childcare discounts too; see employer childcare benefits.
• Cut the hours you need covered. Part-time work, staggered shifts between parents or a remote day or two can reduce paid care to fewer days; see part-time daycare costs. Working from home rarely replaces childcare for young children during work hours.
• Look two to three years ahead. Run the calculator again with your child's next age group. Infant care is the most expensive stage, and costs usually fall at preschool and again at school age.
