After childcare, how much of your paycheck is really left?

Quick snapshot

Start with the numbers that matter most

Choose the pay figure you know, then add childcare and direct workday costs. The first estimate stays intentionally simple.

Use a recent paystub or the after-tax amount from an offer estimate. Do not include employer-paid benefits here.

Include fuel, fares, tolls, or parking you actually expect. This is a planning cost, not a tax-deduction claim.

  • Childcare cash break-even ceiling
  • A 10% childcare-cost stress test

Optional detail

Refine pay and employer benefits

Adjust working weeks, estimated take-home percentage, bonus, and employer-paid benefits only when they improve your estimate.

Used for hourly income and commuting. Reduce this if you expect unpaid or non-commuting weeks.

For example, employer health-plan contribution or retirement match. This is value, not spendable cash.

Optional detail

Add childcare costs beyond tuition

Registration, late coverage, and backup care are optional refinements. The household result always keeps the full amount visible.

Use 100% if you pay it all or 50% for an even split. This changes only the personal-paycheck view; it never reduces the household's total childcare cost.

Optional detail

Add commute time and fixed costs

Keep cash leaving the household separate from the personal value you assign to commuting time.

A subjective decision lens only. It is shown separately and never treated as spendable cash.

Optional detail

Model a Dependent Care FSA carefully

Estimate a possible reduction in taxes using your own election, eligible costs, plan limit, and combined marginal rate.

Estimate only, not tax advice. For 2026, the general federal exclusion limit is $7,500, or $3,750 if married filing separately, but earned-income rules, eligible expenses, employer-plan limits, and coordination with the child and dependent care credit can change the usable amount. Verify your plan and current IRS Publication 15-B.

Optional detail

Compare another schedule

Optionally compare a second childcare quote or onsite schedule with the current plan and a 10% tuition stress test.

Schedule option A

Enter an actual care quote and onsite schedule. Fewer onsite days do not automatically reduce childcare.

Current plan

Uses the main childcare and onsite-day entries above.

10% care + backup stress test

Automatically raises base tuition by 10% and adds the one-time backup-care event below.

How the Decision Lab calculates each layer

Why are there household and personal-paycheck views?

The household view subtracts the full childcare bill from the income modeled here. The personal-paycheck view subtracts only the share assigned to your paycheck or account. A partner split changes who pays, not the family's total cost, so the primary result remains the household view.

What counts as cash after direct costs?

Monthly take-home pay—or estimated take-home from gross pay—plus the modeled FSA tax reduction, minus all-in childcare, commuting cash, and other work costs. Employer-paid benefits and commute-time value are excluded from cash.

How is the FSA estimate constrained?

The estimate multiplies your combined marginal rate by the smallest of your election, eligible care costs, plan or filing-status limit, and modeled household care cost. It does not calculate eligibility, payroll timing, tax-credit interaction, or your tax return.

How is commute time handled?

Onsite days × working weeks × round-trip commute hours creates an annual time total. That total is multiplied by your subjective hourly value and shown only in the time-adjusted layer. It is not income, an expense receipt, or a tax deduction.

What does childcare break-even mean?

It is the estimated all-in monthly household childcare ceiling—tuition plus entered setup, overtime, and backup costs—at which take-home pay plus modeled FSA tax reduction equals commuting cash, other work costs, and childcare. It ignores career growth, job continuity, retirement compounding, personal priorities, and costs that are not entered.

Planning boundary

Illustrative educational estimate only—not legal, tax, financial, employment, benefits, or childcare advice. It does not determine FSA eligibility, tax liability, credits, wage rights, provider suitability, or whether returning to work is right for your family.
