Is It Worth Working After Daycare? (Do the Math)

Every spring, thousands of parents sit at a kitchen table with a daycare contract and a pay stub and ask the same question: is it worth working after daycare costs? The honest answer is that the system has arranged the numbers so that the question has no good answer. Stay, and you may work 2,000 hours to keep a few thousand dollars. Leave, and you pay for it for 30 years. This article runs the math both ways and names the reason it comes out this badly.

Is it worth working after daycare costs in year one?

Start with a common case: two parents, one earning $80,000, the other $40,000, an infant and a toddler in center care. Median household income is about $80,000 (U.S. Census Bureau, 2023), so this household is doing better than most. The table shows where the second $40,000 goes.

Figures rounded and illustrative. Tax owed depends on filing status, deductions, and state.

Forty dollars. That is one number, and it moves. A dependent care FSA adds back about $1,500 in tax savings. A lower-cost state cuts the childcare lines by a third. A single child instead of two turns the net into something closer to $12,000. But the shape of the result holds for a wide band of families: a second earner under roughly $45,000 with two kids in center care works for close to nothing in year one. Our ranking of the cost of daycare by state shows how much the zip code changes the outcome.

Why is the second income taxed so hard?

Because the tax code stacks it on top of the first one.

A married couple files jointly, so the second earner's income does not start at zero. It starts where the first earner's income stopped. In the example above, the household's first $80,000 fills the 10% and 12% brackets, and the second $40,000 spills into the 22% bracket. The second earner faces a higher marginal rate than the first earner on the same dollars. Economists have called this the secondary-earner penalty for decades, and it falls on whichever spouse earns less, which is still usually the mother.

Then add FICA at 7.65% on every dollar, and state tax where it exists. Before childcare enters the picture, the second earner keeps about 70 cents of each dollar. After childcare, in the two-kid case, she keeps almost none.

The tax code's childcare offsets are small. The Child and Dependent Care Credit covers 20% to 35% of up to $3,000 in expenses for one child or $6,000 for two, so a middle-income family gets $600 to $1,200 back against a $26,000 bill. The dependent care FSA lets a family shelter $5,000 pre-tax, a cap Congress set in 1986 and left there for decades while center prices tripled. Neither offset was designed for a world where daycare costs more than college.

What does quitting cost over 10 years?

More than staying, in most cases. The first-year math is real, and it is also incomplete.

A parent who leaves the workforce gives up more than the salary. The raises stop. The 401(k) match stops. The Social Security credits stop accruing. When the parent returns, often five or more years later, the re-entry salary usually sits below where the old one left off, and the gap never fully closes. The Center for American Progress built a calculator around exactly this and found that a multi-year exit costs a mid-income worker several times the wages given up, reaching into the hundreds of thousands of dollars over a career once lost wage growth and retirement savings are counted.

The bill for childcare is temporary. The bill for leaving is not. By the time the younger child enters kindergarten, the same $40,000 job nets close to $25,000 a year with no daycare to pay, and it has been growing while the parent held it. The parent who left is at that point trying to get hired back at less than she made before, with a five-year hole on the resume and five years of missing retirement contributions.

So the short-run answer is "barely" and the long-run answer is "yes, and the short run is a trap." Both are true. The system built a five-year window in which staying employed pays almost nothing and leaving costs a fortune, then told parents it was their choice.

Why do mothers end up making this call?

Because the second earner is usually the lower earner, and the lower earner is usually the mother. BLS data show that roughly two-thirds of mothers with children under six are in the labor force, well below the share for fathers. Pew Research has found that mothers are far more likely than fathers to report cutting hours, turning down promotions, or quitting a job to care for a child.

None of that is a preference the data can measure. It is arithmetic. If one spouse earns $80,000 and the other $40,000, and childcare for two costs $26,000, the household loses less by parking the $40,000 salary. The same logic runs in every kitchen, and it runs against women almost every time. Families who cannot afford either option end up patching care together or living in a childcare desert where there is no slot to price. The infant year is where the decision usually gets forced, because that is when the bill peaks and the paid leave, if any, runs out.

What would make the math work?

The math works in most other wealthy countries, and the fix is not mysterious. Canada capped care at roughly $10 a day. Germany guarantees a slot from age one. France and the Nordic countries subsidize care so heavily that a second earner keeps most of the second paycheck. In those countries, the question in this article's title does not get asked, because the answer is obvious.

In the United States, a family earning $120,000 can watch a second income vanish into a $26,000 childcare bill and a tax code that treats the second earner as a surcharge. Wages did not rise to cover the bill. The offsets Congress wrote were sized for 1986. The full cost of raising a child, commonly cited above $300,000 to age 18, front-loads its worst years into the ones where the household has the least income and the fewest options. The parent doing the math at the kitchen table is not making a bad decision. She is choosing between two bad ones the system laid out for her, and that is what it looks like when the American Dream breaks one paycheck at a time.
