Job offer vs commute
Compare two jobs after tax, mileage, parking and time on the road. See how much more you keep a year and what each extra commute hour costs.
Calculate your true net household take-home pay after marginal taxes, daycare or nanny costs, commuting expenses, Dependent Care FSA savings, and multi-year 401(k) and raise compounding.
Working adds $17,537/yr ($1,461/mo) in net household cash after taxes, childcare, and work costs, plus $2,480/yr in employer retirement match. Over 4 childcare years with 3.5% annual raises, staying employed builds $89,710 in total net wealth.

How annual raises and employer retirement contributions build household net worth until public school begins:
| Year | Gross salary | After-tax pay | Childcare & work | Net cash flow | 401(k) match | Cumulative gain |
|---|---|---|---|---|---|---|
| Year 1 | $62,000 | $43,577 | $26,040 | +$17,537 | $2,480 | +$20,017 |
| Year 2 | $64,170 | $45,060 | $26,040 | +$19,020 | $2,567 | +$41,604 |
| Year 3 | $66,416 | $46,595 | $26,040 | +$20,555 | $2,657 | +$64,816 |
| Year 4 | $68,741 | $48,184 | $26,040 | +$22,144 | $2,750 | +$89,710 |
When couples file jointly, the second earner's salary does not start at the 0% standard deduction bracket. Instead, the first dollar of the second paycheck stacks on top of the primary earner's taxable income. This calculator deducts your household marginal income tax rate plus 7.65% FICA payroll tax, adds back Dependent Care FSA or Child and Dependent Care Tax Credit tax savings, and subtracts full-year childcare and commuting costs.
Focusing only on Year 1 cash in pocket can understate the payoff of staying employed. Childcare costs are temporary (typically 3 to 5 years until public kindergarten), whereas annual merit raises, 401(k) employer matching, and Social Security earnings credits compound over the rest of your career.
On a joint tax return, the primary earner's salary usually uses up the standard deduction and the lower 10% and 12% tax brackets. That means every dollar earned by the second spouse starts in the household's top marginal federal and state bracket, plus 7.65% for Social Security and Medicare.
A Dependent Care Flexible Spending Account lets married couples filing jointly set aside up to $5,000 per year pre-tax for daycare, preschool, or a nanny. At a 24% marginal tax rate plus 7.65% FICA, sheltering $5,000 saves roughly $1,580 per year in taxes.
For household budgeting, childcare is a shared family expense. However, when deciding whether both spouses will work or one spouse will pause their career to provide full-time care, comparing the second salary against avoided daycare and commuting costs shows the true marginal cash impact of working.
Even if Year 1 net cash flow is near $0 or slightly negative (common when two infants or toddlers are in full-time daycare at once), staying in the workforce often still pays off over 3 to 5 years once you include 401(k) matching, annual raises, and avoiding a resume gap penalty when children enter kindergarten.
