Formula and methodology
Formula: In-house total = printer cost + setup cost + in-house unit cost × quantity; outsource total = outsource unit cost × quantity.
The comparison makes fixed and variable costs visible and reports where the variable-cost difference would recover the fixed investment.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Printer purchase cost — currency; minimum 0; maximum 1000000000
- One-time setup cost — currency; minimum 0; maximum 1000000000
- In-house cost per unit — currency/unit; minimum 0; maximum 1000000
- Outsourced cost per unit — currency/unit; minimum 0; maximum 1000000
- Planned quantity — units; minimum 0; maximum 1000000000
Worked example
| Input | Value |
|---|---|
| Printer purchase cost | 1200 |
| One-time setup cost | 200 |
| In-house cost per unit | 4 |
| Outsourced cost per unit | 25 |
| Planned quantity | 100 |
In-house total = 1,800; outsource total = 2,500; savings = 700; break-even ≈ 66.667 units.
Assumptions and limits
- All costs use one currency and the same production scope.
- The in-house and outsourced unit prices are constant across the planned quantity.
- Labor, maintenance, electricity, rejects, delivery, taxes, financing, and machine life are not modeled.
