Put pay, care costs and time on matching bases
The comparison is only coherent when weekly childcare and weekly hours use the same number of work weeks, while pay, deductions and other costs are annual amounts. Enter only costs that belong to the work scenario being tested.
- Annualise 250 of weekly childcare over the same 48 work weeks.
- Count 32 weekly work hours plus 4 weekly commute hours.
- Keep the entered 6,000 deductions separate from the 3,000 other work costs.
- Do not net off a subsidy or credit unless you have independently established and entered its effect.
Separate annual benefit from value per committed hour
Annual childcare cost = weekly childcare cost × work weeks. Annual net benefit = annual pay − entered deductions − annual childcare cost − other annual work costs.
Committed hours = (weekly work hours + weekly commute hours) × work weeks. Value per committed hour = annual net benefit ÷ committed hours. Including commute time answers a personal time-allocation question even though ordinary commuting is not the same as statistical hours worked.
Worked example: what each result answers
| Choice or result | Fixture value | Decision meaning |
|---|---|---|
| Childcare schedule | 250 weekly × 48 weeks = 12,000 | Changing either weekly cost or care weeks tests a different care arrangement. |
| Committed time | (32 work + 4 commute) × 48 = 1,728 hours | This denominator captures time given to the work scenario, not only paid hours. |
| Annual net benefit | 48,000 − 6,000 − 12,000 − 3,000 = 27,000 | This compares entered cash inflows and costs; it is not take-home pay. |
| Hourly and break-even views | 15.63 per committed hour; 21,000 break-even pay | The hourly view supports time comparisons, while break-even shows the pay needed to cover entered costs. |
| Childcare share | 25% of annual pay | This isolates the entered childcare burden; it does not determine affordability or subsidy eligibility. |
Test the costs that can change, then add the factors money misses
Vary childcare weeks, weekly care cost and commute time one at a time. This shows which assumption drives the annual and hourly result and avoids treating one schedule as certain.
The calculation does not infer care availability or quality, career progression, job security, tax, payroll rules, subsidies or credits. Compare those qualitative and local-policy questions separately before acting.

Worked example: Childcare and Work Cost Impact Calculator
The calculator normalizes the inputs above, applies Annual childcare cost, and returns the outputs below. The displayed result is therefore reproducible in the linked calculator.
| Measure | Result | Interpretation |
|---|---|---|
| Annual net benefit | 27,000 currency units/year | Pay less entered deductions, childcare and other work costs. |
| Net benefit per committed hour | 15.63 currency units/hour | Annual net benefit divided by paid work and commute hours. |
| Annual childcare cost | 12,000 currency units/year | Weekly childcare cost multiplied by childcare weeks. |
| Break-even annual pay | 21,000 currency units/year | Entered deductions, childcare and other work costs combined. |
| Childcare share of annual pay | 0.25 share of gross pay | Annual childcare cost divided by annual pay. |
