Childcare alone cannot answer it. Price the first year as a combined stack: take-home pay during leave, when childcare begins, the change in employee health-premium deductions, other new costs, and any change in contributions. Keep contribution interruption separate from child costs. The result shows what changes at these assumptions, not what your family should do.
The first year is a sequence
Most baby-budget pages flatten the question into one national number. Your household does not live in a national average.
A first-child year can include a leave period, a childcare start date, a health-plan change, one-time purchases, and a temporary contribution change. The timing matters. Twelve weeks of leave is about 2.77 month-equivalents. Childcare starting in month four is nine paid months in the first-year view, not twelve.
That is why Aspire keeps the first year editable instead of giving it a yes-or-no verdict.
Paid leave and FMLA are different
The Department of Labor describes FMLA as job-protected leave for eligible employees of covered employers. For birth and bonding, eligible employees may take up to 12 workweeks in a 12-month period. The same DOL fact sheet says FMLA leave is unpaid, although employer-provided paid leave may run at the same time.
That boundary matters. A first-child model should not treat "12 weeks" as 12 paid weeks. It should ask for the household take-home pay expected during leave, including any employer or state paid-leave income the household expects.
The Census Bureau's 2022 SIPP analysis shows why this is not a niche edge case. In the 2014-2022 cohort, 49.1% of first-time mothers and 50.1% of first-time fathers took paid leave. Unpaid leave was still common: 27.3% of first-time mothers and 12.6% of first-time fathers took some unpaid leave after birth. Those are cohort facts, not a prediction of your benefits.
Use a childcare quote, not a national default
Child Care Aware of America estimated a 2025 national average annual childcare price of $13,184, then warned that national averages do not capture state and local differences. Age, care setting, geography, and supply all matter.
The 2025 CPS ASEC working paper offers another national lens. Among households above 400% of the federal poverty level, 33.4% paid for childcare in 2024; households that paid reported a conditional mean of $13,400. That covers households with children through age 13. It is not an infant-care quote, and it should not prefill a personal model.
Use the local provider quote you have. Then choose the month care begins. If there is no childcare in the first year, say that explicitly instead of forcing a zero-dollar quote to stand in for timing.
Health-plan inputs are payroll deductions
The model asks for employee health-premium payroll deductions, not total premiums.
KFF's 2025 Employer Health Benefits Survey found average covered-worker contributions of $1,440 for single coverage and $6,850 for family coverage. Family worker contributions varied by firm size. Those figures are context only. Your benefits portal or pay statement is the better input because Aspire needs the amount leaving your paycheck.
Contribution interruption belongs on the money path
A temporary contribution change should be visible. It should not be counted as a child cost.
If a household contributes $2,500 per month before leave and $500 per month during leave, the $2,000 monthly change affects the money path. Adding that change into the child-cost stack would double-count dollars that may be redirected toward current bills.
Aspire shows it as a separate Money-Path Change. It is excluded from the First-year Transition Stack.
Worked example
This is a hypothetical, editable example. It is not a benchmark.
| Assumption | Value |
|---|---|
| Household take-home pay before leave | $12,000/month |
| Household take-home pay during leave | $8,000/month |
| Leave | 12 weeks |
| Contributions before leave | $2,500/month |
| Contributions during leave | $500/month |
| Childcare quote | $2,400/month |
| Childcare starts | Month 4 |
| Current employee health-plan deduction | $120/month |
| Expected family-plan deduction | $570/month |
| Other recurring costs | $500/month |
| One-time costs | $8,000 |
At these assumptions, 12 weeks is 2.77 month-equivalents. The modeled first-year view is:
| Modeled change | Amount |
|---|---|
| Leave-related take-home-pay interruption | $11,076.92 |
| First-year childcare | $21,600.00 |
| Employee health-premium change | $5,400.00 |
| Other recurring costs | $6,000.00 |
| One-time costs | $8,000.00 |
| First-year Transition Stack | $52,076.92 |
The contribution interruption is $5,538.46. It stays in a separate Money-Path Change card and is not added to the $52,076.92 stack.
What it means
The First-year Transition Stack measures leave-related take-home-pay interruption plus new family costs at the assumptions entered.
It can show which first-year assumptions carry the most weight: leave income, childcare timing, employee health-plan deductions, other recurring costs, or one-time costs.
It does not measure the value of a parent's time. It does not determine FMLA eligibility, state benefit eligibility, tax credits, insurance choices, childcare availability, or employment choices. It does not tell either parent what to do.
What it does not mean
The first-year stack is not a lifetime child-cost estimate. It is not a childcare recommendation. It is not an employment, legal, tax, insurance, investment, or family-planning recommendation.
It is a planning lens: make the assumptions visible, price the first year, then decide whether to run the broader Family goal in Aspire.
Start with the First year + leave mode. The existing care-window calculator is still there for multiyear childcare cost modeling. When you are ready to price the broader goal, open the Family preset or read the methodology.
Educational and assumption-based only. At these assumptions. Aspire does not provide family, employment, legal, tax, insurance, or investment advice.
