Description
Discount a supplied future machinery residual value.
Farm economic terms require explicit cost scope, subsidy treatment, price-index bases, moisture conventions and period rates. A partial input cost per output differs from total economic cost, while an insurance scenario excludes unsupplied policy limits. A nominal margin is conditional on supplied amounts and assumptions.
Discount a supplied future machinery residual value.
When to use this tool
Use Machinery Residual Value Discount when you already have futureResidualValue, perPeriodRate, periods and need to discount a supplied future machinery residual value.
How to use the tool and how it works
- Enter futureResidualValue, perPeriodRate, periods. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read presentResidualValue. Use the output convention below.
Require future value>=0, rate>-1 and periods>=0; return future/(1+rate)^periods.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| futureResidualValue | Future Residual Value | Required. Finite number; minimum 0. |
| perPeriodRate | Decimal rate greater than -1, including negative rates; not a discount factor. | Required. Finite number; strictly above -1. |
| periods | Periods | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| presentResidualValue | futureResidualValue/(1+rate)^periods; a huge denominator can yield zero. | Required. Finite number. |

}Limitations and assumptions
- Rate is per-period decimal and periods can be fractional. No asset, actual residual value, frequency or risk is estimated; an overflowing discount denominator can yield zero.
- 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
Reconcile actual farm accounts, contracts, policy terms and forecasts. Use complete cost, risk and valuation methods when local per-unit terms or scenarios cannot establish profitability, obligations or appropriate financial decisions.
