Is childcare worth it vs staying home?

Every family with a second income eventually does this subtraction: the paycheck, minus the daycare bill, minus taxes, minus the cost of getting to work. Sometimes the answer is uncomfortably close to zero. Here is the break-even math done honestly — this year, and the ten years after it.

$28,750

The median second income at which working breaks even after childcare, taxes, and work costs — from 10,000 family scenarios run through our calculator’s engine. Full methodology in the Second-Income Break-Even Study.

The one-year math

The break-even formula fits on an index card. Take the second income. Subtract income tax on it — at the household’s marginal rate, since the second income stacks on top of the first. Subtract the annual childcare bill. Subtract the cost of working: commuting, work clothes, convenience spending (the takeout that replaces the home-cooked dinner), usually $3,000 to $5,000 a year. What is left is what the job actually pays.

Worked example: a $60,000 second income, one child in full-time center care at the national average ($13,128 a year). Tax at a 22% marginal rate takes $13,200. Childcare takes $13,128. Work costs take $5,000. Remaining: $28,672 — less than half the salary, but decisively positive. Now change one variable: two children in full-time care ($26,256). Remaining: $15,544. Still positive, but the job now pays like a $15,000 job with $60,000 of stress. And at a $35,000 second income with two in care, the remainder goes negative — the family pays for the privilege of the second job.

The tax line deserves emphasis because families consistently misprice it. The second income is taxed at the marginal rate — the rate on the last dollar, which is the household’s bracket — not the average rate. A household in the 22% bracket loses 22 cents of every second-income dollar before childcare takes its share. Using the average rate understates the tax bite by roughly half.

What the one-year math misses

The index-card version is honest but incomplete, and its omissions cut both ways.

On the working side, it omits everything the job buys beyond the paycheck: the employer health insurance (often worth $10,000+ a year for a family plan), the 401(k) match, Social Security credits, and — hardest to price, most important — career continuity. It also omits the non-financial ledger: adult contact, professional identity, and the simple fact that some people are better parents when they are not parenting full-time.

On the staying-home side, it omits the value of the care itself. A parent at home is not just avoiding a $13,128 bill; they are providing the care — usually at a quality no center can match for one child, with flexibility no center offers. It also omits the household production: the cooking, the errands, the logistics that otherwise get outsourced at a premium or done exhausted at 9 p.m.

The ten-year math: where staying home gets expensive

Here is the part the one-year subtraction cannot see. A parent who leaves the workforce for five years does not return at the salary they left. They return below it — research on career interruptions consistently finds wage penalties that persist for years — and the lost ground compounds: lower salary means lower raises (percentages of a smaller base), lower retirement contributions, a smaller Social Security record, and missed promotions that never come back around.

Run a stylized version: a $60,000 earner who stays home five years and returns at $50,000, then grows 3% annually, versus staying at $60,000 growing 3% annually. Over the next ten years the gap in earnings alone is about $115,000 — several times any single year of daycare bills. Add the lost 401(k) contributions and match, and the true cost of the five-year gap lands in the low six figures. The daycare bill is visible and the career cost is invisible, which is why families systematically overweight the first and underweight the second.

This does not mean working always wins. It means the honest comparison is never “this year’s paycheck minus this year’s daycare.” It is the ten-year earnings curve with the gap versus without it, set against ten years of childcare bills that end at kindergarten. Our study ran exactly this comparison across 10,000 scenarios: the median break-even second income came out at $28,750 a year, and in only 7.1% of scenarios did working lose money in the single year — but the career-cost analysis is what moves the decision for everyone near the line.

The new insight

The break-even debate is fought on the wrong time horizon. Price the gap, not the year. Families spreadsheet twelve months of salary-minus-daycare and conclude the second job “barely pays” — then make a five-year decision on twelve months of math. The daycare bill has a fixed end date and a fixed size; the career gap has neither, and its costs compound invisibly while the daycare bill is argued about at the kitchen table. If the one-year math is close, the ten-year math almost always favors working — not because daycare is cheap, but because the gap is expensive. And if the one-year math is clearly negative even before career costs, that is genuine information: the job does not pay, and the honest move is to say so and plan the return deliberately — freelance hours, a kept license, a dated re-entry plan — rather than drifting into a gap with no end date.

The middle paths

The binary — full-time work plus full-time care, or full exit — is a false one, and the data shows families already know it. Care.com’s survey found 27% of parents reduce their hours rather than quitting, and part-time center care roughly halves the childcare bill while preserving career continuity. Staggered shifts (parents covering opposite hours), a four-day week, one remote-work day that eliminates a day of paid care — these compress the $13,128 line without opening the career gap. The cheapest childcare arrangement is not always the one with the lowest bill; it is the one with the lowest bill plus the smallest career cost.

Run your break-even

Plug your numbers into the one-year formula — second income, marginal tax rate, your actual childcare quote, $5,000 for work costs — and see where you land against the $28,750 median. Then read the full study for the distribution: where the break-even sits at your childcare cost, and how often the second job genuinely loses money. And for the eighteen-year context around the decision, our Cost of Raising a Child Calculator prices the whole childhood on the federal figures.

At what salary does it make sense for both parents to work?
Across 10,000 modeled scenarios, the median break-even second income is $28,750 a year after childcare, taxes, and work costs. Below that line the one-year math gets tight — but the ten-year career-cost math usually still favors working.
Should I use my marginal or average tax rate for the break-even?
Marginal — the rate on the last dollar. The second income stacks on top of the first, so it is taxed at the household’s bracket rate (often 22%), not the lower average rate.
Does staying home hurt your career permanently?
It leaves a measurable mark: returners typically re-enter below their exit salary, and the gap compounds through raises, retirement contributions, and missed promotions. The effect fades but rarely fully closes — which is why a dated re-entry plan matters more than the exit decision.
What is the cheapest way to handle childcare and keep working?
Part-time care plus reduced hours: part-time center care roughly halves the $13,128 average bill while preserving career continuity. Staggered shifts and remote-work days compress the bill further without opening a career gap.
