Break Even Calculator
Break even is the number every small biz owner should know cold. Units you must sell before you earn a cent.
Type your costs and price and see that magic number, with the sales cash it means.
Add a goal to see the units needed for it, not just break even.
Your best guess at real demand, so you can see if break even is even possible.
Every unit past this number is profit. This is the number to pin on your wall.
How to use this tool
- 1Price minus unit cost gives profit per unit.
- 2Fixed costs split by profit per unit gives break even units.
- 3Units times price gives the sales cash you need.
The math behind it
Break even units = fixed costs / (price per unit - cost per unit)
Fixed costs 2,000, price 50, unit cost 30 leaves 20 per sale.
2,000 split by 20 means 100 sales to break even.
Who this tool is for
I watch which tools folk open most, and this one gets used by the same kinds of people again and again. If any of these sound like you, you are in the right place.
- New biz owners testing an idea on paper
- Shops planing rent talks and price moves
- Side hustlers checking if the idea is real
I once knew a cafe owner who could tell me her break even to the cup. 63 cups a day. Everything past that was hers. That number ran her life in the best way. This tool gives you your version of 63, and it is the most useful number a small biz can own.
Tips from me
- Every sale above the line is profit. Every one below digs the hole. Know the line.
- Lower fixed costs or raise the per sale gap. Both move the line down.
- Recheck after any price change. A ten percent price move can swing the line a lot.
Mistakes I see with this sum
These are the three slips I made my self or watch folk make most. Skip them and your number will be closer to the truth on the first try.
- 1Using the unit price with out the fees that ride on each sale.
- 2Forgetting your own pay in the fixed costs. You are a cost too.
- 3Never updating it. Costs move, so the number moves.
Two words worth knowing
Fixed costs
Bills that come due no matter what you sell.
Contribution
What each sale adds after its own cost. Price minus unit cost.
That is the whole page. The tool does the math, and the words above give it a shape. If a number still looks odd, change an input and watch what moves. Playing with the boxes taught me more than any guide did.
Common questions
+What are fixed costs?
Costs that do not move with sales. Rent, tools, insurance and your base pay count. Box cost per item does not.
+Can break even be a fraction?
The tool rounds up. You can not sell half a unit, so the honest answer is the next whole one.
+What if my costs change with volume?
Then your per unit cost is not flat. Use the cost at your normal sales level and recheck when volume moves a lot.
+What is the per unit gap called?
Contribution margin. It is the slice of each sale that eats the fixed costs first, then becomes profit.
+Can break even be too far away?
Yes. If the unit count looks like a fantasy, the plan needs a bigger price, a smaller cost or fewer fixed bills.
