Break-Even Calculator

How this result is built

Find how many units you must sell to cover fixed costs at a given price and variable cost.

Break-even units equal fixed costs divided by the contribution of one unit. Contribution is price minus variable cost. Below that unit count, fixed costs are not covered. Above it, each extra unit adds the contribution to profit.

What the opening example is for

The result is a quantity, and it is also a sales figure. If the price does not clear the variable cost, there is no quantity that works. The page says so instead of returning a negative unit count.

The walkthrough below uses the numbers already sitting in Break-Even Calculator. Press Calculate and the headline should match this page. Then put your own figures in. The math does not run until you press the button, and Clear hides the result.

What each field is doing

The “Fixed costs” line on Break-Even Calculator starts at $12,000.00. If the label is a rate, type the annual figure the contract uses. If it is money, type the amount that will actually move, not a rounded hope.

Break-Even Calculator treats “Price per unit” as its own entry, and the form opens with $40.00. Leave that figure only when it matches the statement, the quote, or the plan you are testing. Press Calculate after the edit so the chart and the schedule move with it.

Before you replace it, “Variable cost per unit” reads $18.00 on Break-Even Calculator. A round example is useful for learning the page. It is a poor substitute for the number on your own paperwork, so replace it and run the form again.

The opening result, line by line

Press Calculate on the opening form and Break-even units is 545.45. That is the number the rest of this section is talking about.

Contribution per unit is $22.00 when you run the opening figures on Break-Even Calculator. That line is part of the same calculation as the headline. It is not a second balance you can spend on top of the result. Change one input and press Calculate if you want to see whether this line moves.

On this opening pass, sales needed is $21,818.18. That line is part of the same calculation as the headline. It is not a second balance you can spend on top of the result. Change one input and press Calculate if you want to see whether this line moves.

How those lines were produced

The formula line on the page is Units = Fixed costs ÷ (Price − Variable cost). It is there so you can see the relationship the buttons are using. A schedule, when the page draws one, is that same series written row by row.

A second pass changes only “Fixed costs”, from $12,000.00 to $13,200.00. Break-even units moves from 545.45 to 600.00. Nothing else on the form was edited, so the gap between those two results is the effect of that one field on Break-Even Calculator. If the gap is tiny, this page is not very sensitive to that entry. If the gap is large, get that entry from a document before you plan around the result.

What this page will not claim

Break-Even Calculator uses the operating numbers on the form. It does not file a return, set a price for you, or know which costs your accountant would call fixed. Read the result next to the books, not instead of them.

Break-Even Calculator stops at its own formula. When the next question is different, open Profit Margin Calculator (Gross margin and net margin from the same revenue.); Markup Calculator (Markup on cost, and the margin that creates.); Margin Calculator (Profit as a share of the selling price.). Do not add those results to this one as if they were the same kind of dollar.

Check the result before you use it

Start on Break-Even Calculator by reading the labels, not the headline. The opening labels are Fixed costs ($12,000.00), Price per unit ($40.00), Variable cost per unit ($18.00). If a label is not the fact you have, the result cannot turn into that fact later. The illustration on the form lands on 545.45. When you press Calculate and see that same figure, the button and this explanation are using one formula.

Change one field at a time. Write down the headline, edit a single line, and press Calculate again. A large jump means that line carries the result. A line that does not move is a line the formula ignores, which is a reason to confirm you opened the right page. Break-Even Calculator is built for one job: Fixed costs divided by contribution per unit. The description on the page says the same thing in a sentence: Find how many units you must sell to cover fixed costs at a given price and variable cost.

When the paperwork disagrees

Then hold the headline next to a source outside the site. That source might be a loan estimate, an account statement, a pay stub, or the public limit named in the methodology. A few cents of difference on a long schedule is ordinary rounding. A different rate, a fee you never typed, or a tax the form does not ask for is not rounding. Correct the input. Do not average the page with the paperwork.

When the outside source still disagrees, Break-Even Calculator has reached the edge of what it will claim. It will not phone a lender, pull a county record, or apply a credit you left blank. Send the calculator name, every input, and the result you expected through the contact page if you think the formula itself is wrong. Until that is settled, read 545.45 as the output of the fields above and nothing else.
