The daycare quote arrives and the math looks brutal. The national average price of child care was $13,184 a year in 2025, and two children in care double it. Put that next to a second salary and it is easy to decide that one parent is working just to pay the daycare.
That shortcut is wrong in both directions. Taxes take a bigger bite out of a second paycheck than most couples expect, which makes staying home look better. The child care tax credit, the pay you come back to after five years out and your retirement savings all push the other way.
So we ran the full 2026 federal tax math for three married couples over the five years from birth to kindergarten, using median pay and national child care prices. This is a money comparison only. Whether a parent at home is right for your child and your family is your call.
The assumptions behind the numbers
Assumptions
- A married couple filing jointly, 2026 federal tax rules, standard deduction. State income tax is left out.
- Salaries are the BLS median weekly earnings for full-time men ($1,352, or $70,304 a year) and women ($1,127, or $58,604) in the third quarter of 2026. The $70,304 earner keeps working in every case. Either parent could be the one at home; the math only cares whose salary stops.
- Child care costs $13,184 per child per year, the 2025 national average.
- Five years in today’s dollars, with no raises. Child care prices rose 23% from 2021 to 2025 while prices overall rose 24%, so holding care flat in real terms is reasonable.
- The working couple claims the child and dependent care credit. Both couples get the full $2,200 child tax credit per child, so it cancels out.
- Work hours are 40 a week for 50 weeks (2,000 hours a year). Commuting and other work costs are left out; add your own.
The child care figure comes from Child Care Aware of America, which averages state data for 47 states. Your local price can be far from it. In the Department of Labor’s county price database, the median price of infant care in a center ran from $8,310 in small counties to $17,171 in counties of a million people or more (2018 prices in 2022 dollars). The setting matters too; our daycare vs nanny breakdown prices the alternatives.
What the second paycheck really adds
A second salary is not taxed from zero. It sits on top of the first, which has already used the standard deduction and the 10% bracket. In our couples, every extra dollar pays 12% federal income tax and 7.65% Social Security and Medicare tax, so about 80 cents of each dollar survives before child care. That share falls to about 70 cents once joint taxable income passes $100,800 and the 22% bracket starts.
| Per year | One child, $58,604 salary | Two in care, $58,604 salary | Two in care, $35,000 salary |
|---|---|---|---|
| Second salary | $58,604.00 | $58,604.00 | $35,000.00 |
| Payroll tax (7.65%) | −$4,483.21 | −$4,483.21 | −$2,677.50 |
| Extra federal income tax | −$7,032.48 | −$7,032.48 | −$4,200.00 |

With two children in care, the gain falls to $22,820 a year, because the daycare bill doubles while the credit only rises from $1,050 to $2,100. Those overlap years are the expensive stretch, as our one child vs two article shows. Cut the second salary to $35,000 and the job leaves $3,854.50 a year. That is $1.93 for each hour worked, against $17.48 an hour in the one-child household.
Taxes and credits that change the answer
| Rule, tax year 2026 | Figure | What it does here |
|---|---|---|
| Employee payroll tax | 7.65% (6.2% + 1.45%) | Paid only on wages, so it stops when a parent stops working |
| End of the joint 12% bracket | $100,800 of taxable income | Above it, each extra dollar loses 22% to income tax |
| Joint standard deduction | $32,200 | Already used up by the first salary |
| Child and dependent care credit | 35% of up to $3,000 (one child) or $6,000 (two or more), for AGI of $43,000 to $150,000 | Worth $1,050 or $2,100 to our working couples |
| Dependent care FSA | Up to $7,500 a year | An alternative to the credit, if the employer offers one |
| Child tax credit | $2,200 per child, in full up to $400,000 of joint income | Same for both couples, so it drops out |
The care credit is a two-earner benefit. Married couples filing jointly can claim it only if both spouses have earned income; the IRS makes an exception for a spouse who is a full-time student or disabled. A dependent care FSA follows the same rule. So when one parent stays home, the credit disappears along with the daycare bill. We used the credit because every working parent can claim it; an FSA through an employer can save more at higher incomes.
The credit percentage is also higher than it was. From 2026 it starts at 50% for low incomes and stays at 35% for joint incomes from $43,000 to $150,000. In 2025 it had already dropped to 20% for incomes above $43,000, so a 2025 calculation understates what the second job leaves today.
The hidden cost arrives after you go back
What is opportunity cost?
The income you give up by choosing one option over another. For a parent who stays home, it is the pay they would have earned during the break and the higher pay they might have had after it.
The five-year table counts only the salary you skip. The research says the cost continues after you return. In a classic study of married women in national panel data, Jacob Mincer and Haim Ofek found that real wages at re-entry were lower than when the women left, and the drop was bigger the longer the break. Pay grew quickly after the return, but returnees never fully restored their earning power.
A 2012 study in Demography followed 486 Minnesota women from age 19 to 31. Their hourly wages fell about 0.5% for each month spent neither working nor in school: 3.5% at seven months and 11% at 22 months. Those breaks were much shorter than five years, so don’t multiply that out to 60 months. The direction is clear, though. Hiring is harder too: in a large audit study of job applications, parents who opted out to care for family did worse with employers than parents who had worked continuously, and worse than applicants who had lost a job.
We can’t give you a reliable percentage for your field, so here is the arithmetic instead. If the $58,604 parent comes back earning 10% less than they otherwise would, and the gap lasts 10 years, that is $58,604 before tax: a full year’s pay. At 20%, it is $117,208. Those sums sit on top of the $114,102 to $174,772 of cash the second job would have added during the five years.
Retirement savings and Social Security
Each 1% of salary that an employer matches is worth $586 a year on $58,604, or $2,930 over five years before any investment growth. The at-home parent can keep saving through a spousal IRA: a couple filing jointly can contribute for a spouse with no pay, up to $7,500 in 2026, as long as the working spouse earns enough. At today’s limit that is $37,500 over five years.
Social Security bases your benefit on your highest-earning years: for most retirees, the 40 years from age 22 to 61 minus the five lowest, or 35 years in total. Five years at home cost little here if you still end up with 35 solid years of earnings, and cost the most if you would otherwise have fewer. A spouse can also be paid up to half of the working partner’s primary insurance amount, which puts a floor under many one-income couples. Your Social Security statement shows your own earnings record.
Costs that work adds
Watch out
Going to work has its own costs: commuting, a second car, work clothes, paid lunches, more takeout. We found no reliable national figure, so the table leaves them out. Subtract your own. At $300 a month, they come to $3,600 a year, almost all of the $3,854.50 the $35,000 job adds with two children in care.
State income tax works the same way. It lowers what the second salary keeps, so a couple in a high-tax state should expect a smaller gain than our federal-only numbers show.
Three households, three answers
One child, two median salaries
Second salary $58,604, one child in care at $13,184 a year.
Keep both jobs: about $35,000 a year, $174,772 over five years.
Two in care, two median salaries
Both children in full-time care at the same time.
Keep both jobs: about $22,800 a year, $114,102 over five years.
Two in care, $35,000 second salary
A lower second salary close to the break-even line.
Close call: $3,854.50 a year, or $1.93 an hour. The career cost decides it.
The break-even salary
Below these second salaries, staying home leaves the couple with more cash during the five years. Above them, working wins on cash before you count any career growth or retirement saving.
| Higher earner | Care price per child | One child in care | Two in care |
|---|---|---|---|
| $70,304 | $13,184 (national average) | $15,102 | $30,203 |
| $70,304 | $15,636 (infant in a center) | $18,154 | $36,307 |
| $150,000 | $13,184 (national average) | $17,462 | $35,264 |
Two things move the line most. The first is the price of care: paying infant-center prices pushes the two-child break-even above $36,000. The second is the higher earner’s pay. At $150,000, the second salary is taxed at 22% instead of 12% and the care credit falls to 30% or less, so the break-even rises to $35,264 with two children in care.
Test one income before anyone quits
Tip
For three months, live on the higher salary alone and move the whole second paycheck into savings. Track every dollar, including the work costs you would stop paying. If the budget holds, the plan is real. If it doesn’t, you found out without leaving a job.
Do the same with the other big decisions that tend to arrive with a baby. A larger place often gets added to the plan at the same time; our bigger home after a baby analysis shows why that move rarely pays off early.
Pick for the one-income test: Clever Fox Budget Planner
Good for: a couple running the three-month test on paper. The listing describes an undated planner that covers 12 months, with a calendar, a budget plan and an expense tracker for each month, plus savings and debt trackers. A free spreadsheet does the same job if you prefer one.
Beyond the money
Most couples with young children keep both jobs. In 2025, both parents worked in 62.2% of married-couple families with a child under 6, and the father but not the mother worked in 31.9% of opposite-sex married couples with a child that young, according to BLS family data. A Census Bureau study of mothers’ earnings found a large and persistent drop in earnings after a first child, which grew with later children.
There are middle paths that keep some pay and some time: part-time work, a compressed schedule or working from home. Our work from home vs daycare comparison prices that option. The rest of this decision is about your child, your work and your marriage, and those calls are yours.
Is it worth it?
Verdict: it depends
On cash alone, keeping both jobs wins unless the second salary is below about $15,100 with one child in care or $30,200 with two, at national average prices and 2026 federal tax. A median second salary adds about $35,000 a year with one child and $22,800 with two.
Below the break-even, staying home saves money during the five years, but the return to work is likely to come at lower pay, and the five years of retirement saving and employer match are hard to replace. Staying home is worth it when you value the time more than that gap, and you have tested that the household runs on one income.
Decision rules
- If the second salary is above about $15,100 with one child in care or $30,200 with two, keep both jobs if money decides it. Working leaves more cash every year.
- If you pay more than average for care, use the higher break-even: $18,154 for one child and $36,307 for two at infant-center prices.
- If the second salary is below the break-even, price the return before you quit. A 10% pay cut for 10 years on $35,000 costs $35,000 before tax.
- If one parent stays home, open a spousal IRA. It can take up to $7,500 a year in 2026.
- If you plan to go back, keep some paid work or study going. The research penalizes long breaks with neither.
- If you are unsure, live on one income for three months first and bank the second paycheck.
Frequently asked questions
Is it cheaper to stay home than to pay for daycare?
Only when the second salary is low. With the higher earner at $70,304 and care at the 2025 national average of $13,184 per child, working leaves more cash once the second salary passes about $15,100 with one child in care or about $30,200 with two. Work costs and state tax raise those lines; career growth and retirement saving lower them.
How much does a second income really add after daycare?
In our 2026 federal tax model, a median second salary of $58,604 adds $34,954 a year with one child in care and $22,820 with two, after payroll tax, income tax, the care credit and daycare. A $35,000 salary with two in care adds $3,854.50.
Can a stay-at-home parent claim the child care tax credit?
No. A married couple filing jointly can claim the child and dependent care credit only if both spouses have earned income, unless one spouse is a full-time student or disabled. The same rule applies to a dependent care FSA.
Does staying home hurt Social Security?
It can. Benefits are based on your 35 highest-earning years, so five years at home lower your benefit only if those zero years end up among the 35. A spouse can also receive up to half of the working partner’s primary insurance amount, which cushions one-income couples.
Can a stay-at-home parent still save for retirement?
Yes. A couple filing jointly can fund a spousal IRA for the parent without pay, up to $7,500 in 2026 ($8,600 at age 50 or older), as long as the working spouse has enough taxable compensation. That replaces some of the saving, but not an employer match.
