Description
Multiply nonnegative lostHours by workFraction in [0, 1] for paidWorkHours, then nonnegative wagePerHour for gross cost, and one minus replacementFraction for unreplacedCost.
Health-economic costs depend on resource definitions, perspective, currency, price year, and timing. An incremental or discounted model term uses supplied assumptions without proving treatment benefit or determining an adoption decision.
Multiply nonnegative lostHours by workFraction in [0, 1] for paidWorkHours, then nonnegative wagePerHour for gross cost, and one minus replacementFraction for unreplacedCost.
When to use this tool
Use Health Cost Productivity Time Share Term when you need one transparent health-economic cost or comparison component.
How to use the tool and how it works
- Enter lostHours, workFraction, wagePerHour, replacementFraction. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read paidWorkHours, grossProductivityCost, unreplacedCost. Use the output convention below.

| Input field | Meaning and units | Accepted input |
|---|---|---|
| lostHours | Lost Hours | Required. Finite number; minimum 0. |
| workFraction | Work Fraction | Required. Finite number; minimum 0; maximum 1. |
| wagePerHour | Wage Per Hour | Required. Finite number; minimum 0. |
| replacementFraction | Replacement Fraction | Required. Finite number; minimum 0; maximum 1. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| paidWorkHours | Paid Work Hours | Required. Finite number. |
| grossProductivityCost | Gross Productivity Cost | Required. Finite number. |
| unreplacedCost | Unreplaced Cost | Required. Finite number. |

}Limitations and assumptions
- Fractions are supplied assumptions and wages share the costing currency; this does not estimate actual productivity loss, compensation rights, or a recommended valuation method.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Review the complete economic evaluation, clinical evidence, uncertainty, and relevant decision context separately.
