Straight-line allocates (cost−salvage)/life. Double-declining applies 2/life to opening book value and adjusts the final year to salvage.
- Enter capitalized cost, salvage value, useful life (whole years).
- Check the model, units, and supported limits before calculating.
- Run the tool, inspect the result, then copy or download it.
Good to know
- 1–100 whole years; 0≤salvage≤cost. Book allocation only: no tax filing, MACRS tables, statutory life selection, or partial-year convention.
- Runs locally. Numeric inputs are bounded; floating-point output is approximate and rounded to 12 significant digits. Unsupported or non-finite calculations produce an error.
- Educational user-assumption arithmetic only. No live rates, tax rules, financial advice, or outcome guarantees.
