FSA Dependent Care Calculator (2025)
Estimate Dependent Care FSA tax savings vs the Child & Dependent Care Tax Credit.
TLDR
Dependent Care FSA lets you set aside up to $5,000 (single or MFJ) of pre-tax salary for child care. Tax savings = contribution times (federal + state + 7.65% FICA). The remaining care cost can still claim the Child & Dependent Care Tax Credit, capped at $3K (1 kid) or $6K (2+).
How to use this calculator

- Read the result instantly. Numbers update as you type - no submit button.
- Adjust to test sensitivity. Change one input at a time to see what moves the result most.
- Cross-check the formula in the section below. Calculator math should match the published formula.
- Copy or screenshot the result for later. The site does not save anything; close the tab and inputs are gone.
About this tool + formula
This calculator uses real 2025-26 IRS, SSA, and CMS published values. The math runs entirely in your browser - nothing is sent to a server. The underlying formula is:
fsa_savings = contribution * (federal_marginal + state_marginal + 0.0765) credit_eligible = min(spend, credit_cap) - fsa_contribution credit = credit_eligible * credit_rate(AGI)
Sources: IRS contribution limits, SSA reduction factors, CMS Medicare premium tables, US Treasury auction yields, HHS Federal Poverty Guidelines. Numbers are refreshed annually as new figures publish.
Real-world scenarios where this calculator helps
Two-parent working households
Both parents employed and paying for daycare or after-school. Max out the $5,000 FSA at open enrollment, then claim the Care Credit on any spending above that.
Single parents
Same $5,000 cap, but the credit rate phases up to 35% for low-AGI households. Run both numbers - sometimes the credit alone beats the FSA at very low income.
Live-in nanny / au pair
Wages paid to a household employee count as qualifying expense. So does summer day camp (but not overnight camp).
Aging parent care
If a dependent adult parent lives with you and cannot self-care, their care costs qualify too. Same $5K cap and same credit rules.
What this tool does
- Applies 2025 Dependent Care FSA caps: $5,000 (single / MFJ) or $2,500 (MFS).
- Estimates total tax savings using federal + state + FICA (7.65%).
- Computes the Child & Dependent Care Tax Credit on any care cost above your FSA contribution.
- Phases the credit rate from 35% (AGI <= $15K) down to 20% (AGI >= $43K).
- Compares 'FSA + remaining credit' vs 'credit only' to show the better choice.
What it does NOT handle
- Doesn't include the Child Tax Credit ($2,000 / kid) - that is separate and unaffected.
- Doesn't apply the 'earned income' floor (the smaller of you or your spouse's earned income caps qualifying expense).
- Doesn't model state-specific dependent care credits (CA, NY, MN have their own).
- Doesn't track grace period or carryover policies (varies by employer).
- Doesn't apply if you file separately and live with your spouse - you generally cannot use FSA in that case.
Common mistakes and pitfalls
- Contributing too much. FSAs are use-it-or-lose-it (with limited carryover). Estimate care cost conservatively.
- Forgetting the credit. Even if you max the FSA, spending above $5K can still get the partial Care Credit on the excess up to $6K (2+ kids).
- Counting overnight camp. Only day camp qualifies. Boarding camp does not.
- Using FSA for kids 13 or older. Only kids under 13 (or any disabled dependent) qualify.
- Forgetting that one spouse must have earned income equal to or greater than the FSA contribution.
Frequently asked questions
What is a Dependent Care FSA?
Pre-tax payroll account for childcare or eldercare expenses. 2025 cap: $5,000 (single / MFJ) or $2,500 (married filing separately).
Can I use both FSA and the Tax Credit?
Yes, but not on the same dollars. FSA reduces the credit-eligible expense dollar-for-dollar. Credit cap is $3K (1 kid) / $6K (2+) minus FSA contribution.
Who qualifies as a 'dependent'?
Children under 13, or any spouse / dependent who cannot self-care due to physical or mental disability.
What expenses qualify?
Daycare, preschool, after-school care, summer day camp, in-home nanny / au pair, household employee. Overnight camp, school tuition (K-12), and tutoring do not qualify.
What is the credit rate?
35% if AGI <= $15K, decreasing 1% per $2K of AGI, floor of 20% above $43K.
What if I do not use all the FSA money?
Most plans forfeit unused money at year-end. Some allow a 2.5-month grace period or up to $640 carryover (2025) if the employer opts in.
Can both spouses contribute $5,000?
No. The household cap is $5,000 total. If both spouses elect $5K, only $5K total is allowed.
Does FSA affect the Child Tax Credit?
No. The $2,000 per child Child Tax Credit is independent. FSA only interacts with the Child & Dependent Care Credit.
