Formula and methodology
Formula: Present value of an event = future cash flow ÷ (1 + discount rate)^(event year). At a positive rate, present value of annual costs = annual cost × [1 − (1 + rate)^−cost years] ÷ rate; at zero rate it equals annual cost × cost years. Scenario net present value = PV harvest + PV intermediate revenue − PV annual costs − upfront cost.
This page applies a transparent discounted-cash-flow scenario to a tree or timber investment. It does not appraise an urban tree, predict growth, set a stumpage price, or replace a forester’s inventory and market analysis; every revenue, cost, timing, and rate remains an input.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Future harvest revenue — currency units; minimum 0; maximum 100000000
- Harvest year — years; minimum 1; maximum 200
- Intermediate or thinning revenue — currency units; minimum 0; maximum 100000000
- Intermediate revenue year — years; minimum 0; maximum 199
- Annual management cost — currency units/year; minimum 0; maximum 10000000
- Years of annual cost — years; minimum 1; maximum 200
- Upfront establishment cost — currency units; minimum 0; maximum 100000000
- Annual discount rate — %; minimum 0; maximum 100
Worked example
| Input | Value |
|---|---|
| Future harvest revenue | 2800 |
| Harvest year | 30 |
| Intermediate or thinning revenue | 500 |
| Intermediate revenue year | 14 |
| Annual management cost | 5 |
| Years of annual cost | 30 |
| Upfront establishment cost | 250 |
| Annual discount rate | 6 |
The entered scenario has a present harvest value of about 487.5, intermediate revenue value of about 221.2, annual-cost present value of about 68.8, and an estimated net present value of about 389.8 currency units.
Assumptions and limits
- All monetary inputs use one consistent currency or currency unit; no exchange rate is applied.
- Harvest and intermediate revenues occur at the entered end-of-year points.
- Annual management cost is paid once per year for the entered number of years.
- The discount rate is a nominal scenario rate entered as a percentage and converted to a decimal.
- Zero discount rate is handled as undiscounted cash flow rather than divided by zero.
- The model does not estimate tree growth, volume, species price, mortality, land value, taxes, or inflation.
- Harvest year and intermediate timing are supplied by the visitor and are not validated against a biological rotation model.
- A positive NPV means the entered cash flows exceed the entered discount hurdle in this simplified scenario.
- A negative NPV is not a valuation of the tree’s ecological, cultural, shade, or amenity benefits.
- Forestry, arboricultural, land, and tax decisions require local professional and jurisdictional review.
