Childcare costs end; a career gap keeps costing in lower pay, lost retirement saving and Social Security credits. A year with a small or negative net can still be the cheaper path over a decade. IRS Publication 503 covers the credit rules.

A decision with numbers on both sides

When childcare takes a large share of one paycheck, it is worth knowing the net figure. It is one input into a decision that also involves careers, health and family.

How the calculation works

Net cash = gross pay × (1 − tax rate) − childcare − work costs + dependent care credit or FSA saving

$48,000 of pay taxed at 30% leaves $33,600. Subtract $16,000 of childcare and $3,000 of work costs, add $1,200 of dependent care tax savings, and the job adds $15,800 a year, about $1,317 a month. Childcare takes 48% of that earner’s take-home pay. A $1,400 retirement match adds to the total.

What the number leaves out

Childcare costs fall as children reach school age; time out of work can lower future pay and retirement saving. A short-term negative figure can still be the better long-term choice. IRS Publication 503 explains the child and dependent care credit and dependent care FSA rules.

Frequently asked questions

What tax rate should I use?
The household’s marginal federal rate plus the state rate and 7.65% for Social Security and Medicare, because the second income is taxed on top of the first.
What is a dependent care FSA?
An employer account that lets you pay for childcare with pre-tax money, up to an annual limit set by law.
Does this count Social Security credits?
No. Working also earns Social Security credits and raises future benefits, which this calculator does not price.
