Calculate break-even sales
Calculates how many units you need to sell to cover the specified costs.
Tells you how many units cover your fixed costs. It works from the contribution margin: what is left of the selling price once variable costs are taken off.
- Enter your fixed costs
- Set the variable cost and selling price per unit
- Read off the break-even quantity and the revenue it takes
If the price does not exceed the variable cost there is no break-even — the tool says so plainly rather than printing a meaningless number.
Frequently asked
What does it cost?
Every tool shows its price before you start. Tools marked free run in your browser and never cost anything — no sign-up needed.
What happens if processing fails?
You are not charged. We only charge when a result is actually produced; if the run fails, the charge is reversed.
What happens to my files?
Uploaded files are processed in memory for that one request and then discarded. We do not store them, and their contents never reach our logs or analytics.
Do you use my own API key?
No. Your BYOK key belongs to the Playground and is never used for these tools.
