Guide written .
Open the Asset depreciation calculatorWhat to prepare
- Gather supplier quotes, invoices, time records and the actual scope of the job or business decision.
- Separate revenue from VAT, direct costs from overheads, and profit from the timing of cash receipts.
- Use the same accounting period and currency for related inputs.
Understand the inputs
- Method
Options: Straight line; Reducing balance.
The calculation method
Straight-line spreads depreciable cost evenly; reducing balance applies a fixed annual rate above the residual floor.
Worked example
Illustrative inputs and their result.
Example inputs
- Asset cost (€)
- 10000
- Minimum residual value (€)
- 1000
- Years
- 5
- Method
- Straight line
- Reducing-balance annual rate (%)
- 20
Calculated example result
- First Year Depreciation
- €1,800.00
- Final Book Value
- €1,000.00
How to interpret the result
A profitable estimate can still create a cash shortfall. Read the cost and timing assumptions as well as the headline profit, price or return; the result is a scenario, not a sales forecast.
Keep the scope constant while changing price, volume, supplier cost or time. A lower-sales or higher-cost case helps show whether the decision depends on an optimistic assumption.
Common mistakes to avoid
- Do not confuse markup on cost with margin on selling price.
- Include work that is easy to miss, such as travel, setup, rework and administration, where the model supports it.
- Do not treat tax collected or an unpaid invoice as freely available cash.
Assumptions and sources
Accounting depreciation does not automatically equal an Irish tax deduction.
