Description
Return trees*perTree+sharedCost-grant and its per-tree equivalent.
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.
Return trees*perTree+sharedCost-grant and its per-tree equivalent.
When to use this tool
Use Agroforestry Establishment Cost Tree Share when checking the stated tree/crop cost, labor or discounted-benefit contribution.
How to use the tool and how it works
- Enter trees, perTree, sharedCost, grant. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read totalCost, netPerTree. Use the output convention below.
Require whole trees>=1 and nonnegative per-tree cost, shared cost and grant. Return trees*perTree+sharedCost-grant and its per-tree equivalent.1

}Limitations and assumptions
- A grant can exceed gross cost and produce a negative balance; no actual eligibility or entitlement is established.
- 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
Build a complete budget with verified costs, timing, uncertainty and applicable agreements for actual investment, labor or grant decisions.
