CennikTo calculator methodology
The calculators separate cost, price, profit, margin and risk. Every calculation runs locally and the core formulas are documented below.
Core principles
- Cost includes labor, purchases and allocated overhead.
- Price is the selling amount before taxes specific to the user.
- Profit is price less full cost.
- Margin = profit ÷ price.
- Markup = profit ÷ cost.
Key formulas
| Tool | Simplified formula |
|---|---|
| Hourly rate | (annual income + annual costs + reserve) ÷ billable hours |
| Project price | (time × rate + costs + buffers) ÷ (1 − margin) |
| Break-even | fixed costs ÷ (unit price − variable cost) |
| Minimum price | protected cost ÷ (1 − margin − fees) |
Assumptions and limits
The tools do not fetch market rates, exchange rates, taxes or social contributions. Results depend on user inputs and support planning. Check your own tax duties and contract terms before making a business decision.
