Useful next calculations
When to use this calculator
- Before pricing a job, setting margin targets or reviewing hiring costs.
- When you want to test sensitivity around volume, tax, markup or overheads.
- When you need a practical estimate before committing to a budget or proposal.
- When you are modelling break-even volume as costs or prices change.
A worked example
These are the example figures the calculator opens with.
| Input | Value |
|---|---|
| Total Cost (€) | €5,000 |
| Number of Units | 100 |
For those figures the calculator returns:
- Cost per unit: €50.00
- Total cost: €5,000.00
- Units: 100
Method & assumptions
This calculator divides your total production costs by the number of units produced to give you the cost per unit. Total costs should include direct materials, direct labour, and an appropriate share of fixed overheads such as rent, insurance, and equipment depreciation. The calculator assumes a single product or batch; if you make multiple products, allocate shared overheads using a consistent method such as machine hours or labour hours before entering figures.
It does not account for spoilage rates, wastage, or rework — add a buffer to your inputs if these are significant in your process. The result is a breakeven floor; your actual selling price must exceed this figure to generate profit. Always recalculate when input costs change.
Common mistakes
- Using an assumption that is not supported by a current local quote, bill, statement or official source.
- Treating a generic estimate as a lender, provider, payroll or tax authority decision.
- Mixing monthly and annual inputs without converting them consistently.
- Testing only one scenario instead of checking how a cautious assumption changes the result.
What to do next
- Run a second scenario with a cautious assumption so you can see the downside clearly.
- Compare the result with the related calculators below before making a decision.
- Check current local rules, eligibility and provider terms before applying or committing money.
- Keep a record of the assumptions so you can update the estimate when a quote, bill or pay figure changes.
