Description
Calculate one option grant’s gross exercise cash, net cash after supplied withholding and unexercised count.
Startup cash budgets distinguish available funds, committed outlays, restricted balances and expected receipts. Subtracting commitments can create a negative balance even while total cash remains positive; dividing by burn assumes a constant spending rate.
Calculate one option grant’s gross exercise cash, net cash after supplied withholding and unexercised count.
When to use this tool
Use Option Exercise Cash Inflow One Grant when checking a supplied cash commitment, balance or runway contribution.
How to use the tool and how it works
- Enter vested, exercised, strike, taxWithheld. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read grossCash, netCash, unexercised. Use the output convention below.
Require nonnegative whole vested and exercised <= vested and nonnegative strike and taxWithheld. grossCash = exercised*strike; netCash = grossCash-taxWithheld; unexercised = vested-exercised.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| vested | Vested | Required. Safe integer; minimum 0. |
| exercised | Exercised | Required. Safe integer; minimum 0. |
| strike | Strike | Required. Finite number; minimum 0. |
| taxWithheld | Tax Withheld | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| grossCash | Gross Cash | Required. Finite number. |
| netCash | Gross exercise cash minus supplied withholding under this tool convention. | Required. Finite number. |
| unexercised | Unexercised | Required. Safe integer. |

}Limitations and assumptions
- This convention subtracts the supplied withholding from gross exercise cash. It does not determine who remits tax, compute a tax obligation or establish actual company receipts.
- 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
Use a dated cashflow forecast and the actual funding or payment terms when timing, changing burn or enforceability matters.
