How to use it

Enter gross monthly salary, effective tax rate, monthly childcare cost, commute cost, work wardrobe and meals budget, and any other work-related expenses like parking or dry cleaning.
Read net take-home after all work costs. This is what returning to work actually adds to household income. If it is near zero or negative, the financial case is weak.
Check the effective hourly rate. Divide your net take-home by 160 working hours to see what you really earn per hour after all costs. Below $10-15/hour changes the calculus.
The break-even childcare cost shows the maximum you can pay for childcare before working costs more than staying home. Use this to evaluate different childcare options.
Re-run when childcare costs change, when you get a raise, or when commute options shift. Consider non-financial factors like career continuity and retirement benefits alongside the numbers.

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 should I include?

Include childcare (daycare, nanny, or after-school care), commute costs (gas, transit, parking), work wardrobe and dry cleaning, work meals and coffee, and any other costs that only exist because you work — like house cleaning or dog walking you would not need otherwise.

What is the effective hourly rate?

Your net take-home after ALL work costs, divided by working hours (typically 160/month). If you earn $5,000/month gross, pay $1,500 in taxes, and $2,000 in work costs, your effective hourly rate is $9.38/hour — less than minimum wage in many states.

When is it not worth returning to work financially?

When the effective hourly rate is below $10-15/hour, the financial case is weak. However, non-financial factors matter: career continuity, Social Security credits, retirement plan contributions, professional development, and mental health.

What about the long-term career cost of not working?

Career gaps can reduce lifetime earnings by 10-30% through missed raises, promotions, and skill atrophy. Women who leave for 3+ years often return at lower pay. This calculator shows the short-term math; long-term career impact is separate.

Does this account for tax benefits like the child care credit?

Not directly. The Dependent Care FSA ($5,000 pre-tax) and Child and Dependent Care Credit (20-35% of up to $6,000) can reduce the effective childcare cost. Subtract these benefits from your childcare input for a more accurate result.
