Unpaid Work Calculator

The unpaid work calculator puts a money value on household labor that usually does not appear on a paycheck. It adds weekly hours for cooking, cleaning, laundry, care, errands, repairs, pet care, and yard work. Then it reports two different values: the replacement cost of hiring equivalent help and the opportunity cost of valuing those same hours at your own hourly wage.

Unpaid work is economically important because it creates real services: meals are prepared, children and adults are cared for, homes are maintained, and errands are completed. The calculator does not say a family member owes that amount of money. It gives a structured estimate that can support budgeting, task-sharing conversations, outsourcing decisions, and recognition of care work that is often invisible.

How to use this calculator

Select a country so the result uses the matching currency and the calculator’s built-in country rate table. Enter your hourly wage as the pay rate you earn or could reasonably earn. Enter paid work hours per week for comparison; this does not change the unpaid-work value, but it produces a weekly paid-earnings line. Then estimate the hours you spend in each unpaid-work category during a usual week.

If a category does not apply, enter zero. For tasks that happen unevenly, convert to a weekly average. Two hours of errands every other week is one hour per week. A six-hour repair project once per quarter is about 0.46 hours per week. To connect the estimate with other money decisions, compare it with the budget calculator, the salary calculator, and the savings goal calculator. If household costs are changing over time, the inflation calculator can help you update assumptions.

Formula

Replacement value adds each task category separately:

$\text{replacement cost per week} = \sum(\text{task hours} \times \text{task outsourcing rate})$

Opportunity cost uses one wage for all unpaid hours:

$\text{opportunity cost per week} = \text{total unpaid hours} \times \text{hourly wage}$

Annual values multiply weekly values by 52:

$\text{annual replacement value} = \text{replacement cost per week} \times 52$

$\text{annual opportunity cost} = \text{opportunity cost per week} \times 52$

The paid-work comparison is:

$\text{paid work earnings per week} = \text{hourly wage} \times \text{paid work hours}$

The calculator rejects negative hours, negative wages, and negative paid-work hours. The currency changes with the selected country, but the logic is otherwise the same.

Checking the primary result

Use the default United States inputs: hourly wage $25, paid work 40 hours, meals 7 hours, cleaning 3, laundry 2, child care 5, adult care 0, pet care 1.5, transport and errands 2, repairs 0.5, and gardening 1. Total unpaid time is 22 hours per week.

The U.S. replacement-rate table in the calculation values those categories at $22, $28, $18, $24, $27, $17, $23, $45, and $30 per hour respectively. The replacement calculation is $154 for meals, $84 for cleaning, $36 for laundry, $120 for child care, $0 for adult care, $25.50 for pet care, $46 for transport, $22.50 for repairs, and $30 for gardening. Added together, the primary result is $518 per week.

Annual replacement value is $518 × 52, or $26,936. Opportunity cost is 22 hours × $25, or $550 per week, and annual opportunity cost is $28,600. Paid work earnings per week are $25 × 40, or $1,000. Because $550 is higher than $518, the note says the unpaid work is worth about $550 per week using your wage.

How to use the estimate

Replacement cost is helpful when the question is, “What would we pay someone else to do this?” It supports decisions about hiring a cleaner, paying for child care, ordering prepared meals, or outsourcing repairs. Opportunity cost is helpful when the question is, “What paid work, rest, study, or career time is displaced by these hours?” Neither number captures love, responsibility, quality, or family preferences, but both make the time visible.

Review the result by category. A high total may come from one task that could be shared or outsourced rather than from every chore. A lower total may still represent meaningful stress if the work occurs at difficult times of day. Rates and wages change, so revisit the estimate when pay changes, care needs shift, children age, or local service prices rise.

Common mistakes

• Counting only visible chores and forgetting planning, appointments, transport, and care coordination.
• Comparing a weekly unpaid-work value with monthly income without converting periods.
• Treating built-in rates as exact local quotes.
• Entering paid work hours as if they change replacement cost; they only affect the paid-earnings comparison.
• Assuming outsourcing is all-or-nothing when a few targeted services may free the most valuable time.
