How many units do you actually need to sell before you stop losing money? Most people starting a business can name their price and their costs but not that number. The Break Even Calculator works it out from figures you already have, and shows the arithmetic behind it.
Short answer: The Break Even Calculator is a free tool on EizTools that finds the sales volume where revenue covers costs. Enter your fixed costs, unit price and variable cost, and it returns the break even point with the working shown.
What is Break Even Calculator?
It answers one question: at what point does the money coming in match the money going out. Type what you want to calculate into the prompt box, in plain words, and the Break Even Calculator returns the number of units, the revenue figure that matches it, and the steps in between.
The Number Every New Business Needs
Break even sits underneath every pricing decision. Drop your price and the number of units goes up. Take on a bigger workshop and your fixed costs rise, so the number moves again. Knowing it turns "can I afford this?" into arithmetic instead of a feeling.
What it does well
- Handles the calculation from a plain sentence, with no form to fill in
- Show Formula puts the equation next to the answer, so you can check it
- Format set to Table lays out several price points side by side
What to keep in mind
- An AI model does the arithmetic, so verify anything you are betting money on
- It works from the numbers you give it, and a forgotten fixed cost changes everything
- It cannot know your tax position, which sits outside a break even sum
Reading The Break Even Point
| Option | What it changes | Suggested setting |
|---|---|---|
| Calculation Type | The kind of maths applied, from General to Finance or Statistics | Finance, which frames the answer in business terms |
| Format | Plain, Table, Step-by-Step or Formula + Result | Formula + Result, so the equation is visible |
| Precision | Auto, 2 Decimals, 4 Decimals, Whole Number or Exact | Whole Number, because you cannot sell part of a unit |
Four toggles sit under those dropdowns: Show Steps, Explain, Show Formula and Round Result. Turning Explain on gives a short reading of the answer in words, which is the difference between a number and knowing what to do about it. The Detail Level slider decides how much of that explanation you get.
How Does Break Even Calculator Work?
Take a candle maker working out whether a market stall is worth it.
- Type the situation: "fixed costs 900 a month, candles sell for 18, materials and packaging cost 6.50 each, find my break even."
- Pick a model from the selector at the top of the page.
- In advanced options choose Finance as the Calculation Type, Formula + Result as the Format, and Whole Number precision.
- Turn on Show Formula and Explain.
- Press Generate and read the output card.
- Run it again with the price at 20 to see how the number moves.
The answer comes back as units per month, with the contribution per candle shown in the working. The activity history keeps both runs, so the two price points sit side by side while you decide.
Note List every fixed cost before you start, including the ones that feel small. Insurance, stall fees and software all belong in the total, and leaving them out gives you a break even point you will never actually hit.
Who Should Run It
- Anyone pricing a product for the first time
- Freelancers deciding whether a retainer covers their fixed costs
- Small shops weighing up a rent increase against their volume
- Side projects working out how much of a hobby has to sell to stop costing money
EizTools is a free platform built around one tool per job, with no account needed and a choice of AI model families on every page. Break even is one input into a bigger decision, so the SWOT Analysis Generator is a useful companion when the question is not only whether the numbers work but whether the idea does. More sit in the tool library.
Frequently Asked Questions
What figures does the Break Even Calculator need?
Three: your total fixed costs for a period, the price you sell at, and the variable cost per unit. Anything else you add, such as a target profit, refines the answer rather than replacing those.
Can it handle a service business?
Yes. Replace units with billable hours or projects and give the cost per hour. The arithmetic is the same, and naming the unit in your prompt keeps the answer readable.
Is the answer accurate enough to plan with?
Treat it as a working figure and check the arithmetic on anything important. The maths is simple enough to verify in a minute, and the tool shows the formula when you ask it to.
Should I include my own wages?
If you are paying yourself a set amount, yes, put it in fixed costs. A break even point that quietly assumes you work for nothing is the most common mistake in a first calculation.
Break even is not an exciting number, but it is the one that tells you whether a price works. Give the tool your real costs, check the formula it shows, and run the sum again whenever a cost or a price moves.
