This Unpaid Work Calculator estimates the annual economic value of household labor by combining logged task hours, with a professional wage and a replacement cost per hour of work.
Unpaid Work Calculator: Estimate the Economic Value of Household Labor
This Unpaid Work Calculator totals weekly hours spent on household tasks such as meals, caregiving, and admin, then values those hours using both a replacement-cost rate and a professional opportunity-cost wage. It is used by people who want to see what their uncompensated household labor would cost to replace, and how delegating part of it would change that figure.
Unpaid Work Calculator Inputs: Wage, Replacement Cost, and Six Task Categories
Enter Professional Hourly Wage, Professional Hours per Week, Replacement Cost per hour, hours per week across six household task categories, and Target Hours to Delegate. The calculator outputs an annual replacement-cost value, an opportunity-cost comparison, delegation savings, and a blended paid-plus-unpaid hourly rate, with no compounding applied.
How the Unpaid Work Calculator Values Hours Using Replacement Cost and Opportunity Cost
Total Unpaid Hours sums the six weekly task categories (Meals & Cleaning, Laundry & Home Upkeep, Child & Adult Care, Schoolwork & Admin, Pet Care & Gardening, and Transport & Repairs). The calculator then applies two standard methods for valuing unpaid household work documented in national accounting research, including UN System of National Accounts guidance and OECD analysis of household production: the replacement cost method and the opportunity cost method.
$$\text{Replacement-Cost Value} = \text{Total Unpaid Hours} \times \text{Replacement Cost} \times 52$$
$$\text{Opportunity-Cost Value} = \text{Total Unpaid Hours} \times \text{Professional Hourly Wage} \times 52$$
These are two separate, standard valuation conventions rather than a single official rate, and they rarely produce the same number. The hero figure and Total Economic Footprint specifically use the replacement-cost value.
Not the opportunity-cost value — a distinction worth noting, since combining Paid Income with the opportunity-cost figure instead would effectively double-count the same hours against two different wage rates. A common input mistake is entering a net, take-home wage in Professional Hourly Wage rather than the gross figure, which understates the Opportunity Cost Matrix comparison.
Replacement Cost must be entered as a number greater than zero, even though it isn’t used as a divisor anywhere in the calculation — this is a deliberate constraint that keeps the tool from displaying a zero-dollar valuation for unpaid labor.
Professional Hourly Wage and Professional Hours per Week can both be zero, which lets someone not currently in paid work still get a replacement-cost valuation, while the Opportunity Cost Matrix and Time Ratio figures fall to zero accordingly.
Target Hours to Delegate cannot exceed Total Unpaid Hours, since delegating more hours than are actually spent is not a valid scenario; the six task category fields each accept zero independently.
None of this is a legal, insurance, or settlement valuation — the figures are illustrative estimates based on the wage and replacement-cost numbers entered, not a market rate any individual would actually receive if the underlying tasks were formally compensated.

Unpaid Work Calculator Questions: Valuation Methods, Delegation, and Edge Cases
Why do the hero figure and the Opportunity Cost Matrix show different dollar amounts?
The hero figure and blended totals use the replacement cost method, valuing unpaid hours at the entered Replacement Cost. The Opportunity Cost Matrix card shows a separate figure using your Professional Hourly Wage instead — the two methods rarely match.
Can Replacement Cost or Professional Hourly Wage be entered as zero?
Replacement Cost must be greater than zero, since the calculator’s core valuation depends on it; Professional Hourly Wage and Professional Hours per Week can both be zero, for someone not currently in paid work.
What happens if I set Target Hours to Delegate too high?
Target Hours to Delegate cannot exceed Total Unpaid Hours, since delegating more hours than are actually spent on unpaid tasks is not a valid scenario the calculator is built to represent.
Which valuation method feeds into Total Economic Footprint?
Total Economic Footprint adds Paid Income to the replacement-cost value of unpaid hours, not the opportunity-cost value, so it reflects what your combined labor would cost to replace, not what you could have earned instead.
Can I leave a task category at zero if it doesn’t apply to me?
Yes. Each of the six task categories accepts zero hours independently, so someone without pets, a yard, or dependents can leave those fields at zero without affecting the other categories or halting the calculation.
