Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Single product, constant price/cost and whole sold units. Capacity and demand limits are not checked.
Example Calculation
- Fixed cost: 1000
- Unit price: 20
- Variable unit cost: 12
- Target operating profit: 600
Fixed cost = 1000; Unit price = 20; Variable unit cost = 12; Target operating profit = 600. The primary result is 200.
Frequently asked questions
How do I use this calculator?
Enter fixed cost, unit price, variable unit cost, target operating profit. The result updates automatically. Use Reset to restore the example values.
What method does it use?
units=ceil((fixed costs+target profit)/(price−variable cost)).. Single product, constant price/cost and whole sold units. Capacity and demand limits are not checked.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
