Description
Person-hours=units*minutes/60; elapsed hours divide by workers; cost multiplies person-hours by hourlyCost.
Agroforestry cost and benefit terms depend on labor exposure, shared allocations, grants and discount periods. Person-hours differ from elapsed crew-hours, and a single discounted benefit differs from a complete investment appraisal. Prices, allocations and discount rates must be supplied on compatible bases.
Person-hours=units*minutes/60; elapsed hours divide by workers; cost multiplies person-hours by hourlyCost.
When to use this tool
Use Agroforestry Harvest Labor One Component when checking the stated tree/crop cost, labor or discounted-benefit contribution.
How to use the tool and how it works
- Enter units, minutesPerUnit, workers, hourlyCost. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read personHours, elapsedHours, laborCost. Use the output convention below.
Require whole workers>=1 and nonnegative units, minutes per unit and hourly cost. Person-hours=units*minutes/60; elapsed hours divide by workers; cost multiplies person-hours by hourlyCost.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| units | Units | Required. Finite number; minimum 0. |
| minutesPerUnit | Minutes Per Unit | Required. Finite number; minimum 0. |
| workers | Workers | Required. Safe integer; minimum 1. |
| hourlyCost | Currency per person-hour, not currency per crew-hour. | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| personHours | Person Hours | Required. Finite number. |
| elapsedHours | Person-hours divided by worker count under ideal equal parallel allocation. | Required. Finite number. |
| laborCost | Labor Cost | Required. Finite number. |

}Limitations and assumptions
- Assumes equally shared work without setup or interference; hourlyCost is per person-hour, not per crew-hour.
- 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.
