How to use it

Enter nanny hourly rate, expected weekly hours, payroll taxes, workers comp, backup-care days, and benefits versus daycare monthly tuition, registration fees, supply fees, and schedule gaps requiring additional coverage. Include the real cost of sick days and closures.
Read total annual cost for each option and the monthly difference. Nanny costs often run 30%-50% higher than center-based daycare before tax benefits, but the gap narrows with two or more children.
If the cost difference is small, convenience, flexibility, child temperament, and schedule fit should drive the decision. If the nanny option is dramatically more expensive, confirm you are accounting for the dependent care FSA and child tax credit in both scenarios.
Model a nanny-share arrangement if solo nanny cost is too high, and check whether your employer offers dependent care FSA or backup-care benefits that change the math. Use the childcare vs take-home pay calculator to see net income impact.
Re-run when rates change, a child ages into a different program, or your work schedule shifts. Track all-in monthly cost, effective hourly rate of care, and the cost per child if you have multiples.

Agent FAQ

Should ChatGPT, Claude, or another agent click through the UI?

No. Start with /agent-tools.json, then follow the tool's contract URL. The page UI is for human review, not parameter discovery.

When do tools show Quick and Advanced?

Every tool opens in Quick Start first. Advanced Controls keeps the same scenario, reveals more assumptions or diagnostics, and every tool keeps AI integrations inline below the instructions.

When should an agent still open the browser page?

Open it when a human wants to sense-check the output, review the chart, or keep exploring related tools after the calculation finishes.

Questions people usually ask

What costs does this compare?

It models the full cost of a nanny (salary, payroll taxes, insurance, PTO, overtime) versus daycare (tuition, registration fees, supply fees, schedule gaps requiring backup care). Many families underestimate nanny costs by 25-40% by ignoring employer tax obligations.

Is paying a nanny under the table a real option?

No. Paying a nanny off the books is illegal (the nanny tax threshold is just $2,700/year), eliminates your ability to use a Dependent Care FSA ($5,000 tax-free), and exposes you to back taxes, penalties, and interest if audited. The tool models legal, on-the-books costs.

How much does a nanny actually cost vs daycare?

Nationally, a full-time nanny costs $35,000-$55,000/year after taxes and benefits, while daycare runs $12,000-$25,000/year per child. The gap narrows significantly with two or more children, since nanny cost stays roughly constant while daycare doubles.

When should I use this vs a general budgeting tool?

Use this for the specific nanny-vs-daycare decision. It captures costs unique to each option (employer taxes for nannies, waitlist fees for daycare) that a general budget tool would not itemize.
