How to Create Break Even Chart in Excel

What this does

The break-even point is where revenue covers all costs. The denominator (price minus variable cost) is the contribution margin: what each sold unit contributes toward fixed costs. Divide fixed costs by it and you get the number of units at which profit is exactly zero — every unit beyond that is profit. The same idea underpins a lot of everyday Excel work, so the few minutes spent getting it right here pay back across every sheet you build afterwards. Treat it as a pattern, not a one-off, and it stops being something you look up and starts being something you reach for. Treat “create break even chart in excel” as a small repeatable workflow rather than a one-off click you hope to remember next time. Use a small test block before the live file, so any surprise in the affected chart shows up while it is still harmless. When a formula is involved, keep the inputs labelled beside it, reference cells instead of typing values, and apply number formatting only after the result checks out. That turns a visual that makes the number obvious at a glance into a method you can reuse, explain, and defend when the workbook leaves your screen.

A worked example

Fixed costs are €5,000 per month, the product sells for €25, and each unit costs €15 to make. =5000/(25-15) returns 500 units; break-even revenue is 500×€25 = €12,500. At 499 units the month is a loss; at 501 it is profitable. Break-even is the first sanity check for any product, side project, or pricing change: how many sales until this stops costing money? If there is any chance you will reuse this, drop it into a small template tab right now: a labelled input area on the left and the formula beside it, checked once against the tool above. Next time the same question comes up, the answer is a single paste away instead of a rebuild from memory.

In Google Sheets

If you are in Google Sheets rather than Excel, the good news is that the formula shown here is identical and the workflow barely changes — menus sit across the top instead of in a ribbon, and a few function names differ slightly, but anything you build here moves across with little or no rework. The aim was to get you unstuck fast and leave you a little more capable than a copy-paste would. The answer is at the top, the tool proves it, and the detail above shows why it holds — so the next time a colleague asks, you can answer without reaching for search. Treat “create break even chart in excel” as a small building block rather than a chore. Once the inputs sit in their own cells and the formula reads from them, the same setup answers a dozen related questions with a tweak, and Excel keeps every dependent figure current as the data changes. The tool above is there so you can rehearse and verify before committing anything to a real workbook; the steps and worked example are there so the logic sticks. Get it right once and it stops costing you time — it starts saving it, every time the question comes back around.

Common mistakes

• Mixing time frames — monthly fixed costs against an annual sales target.
• Forgetting per-unit costs like shipping or payment fees in the variable cost.
• A price below variable cost: the margin is negative and no volume ever breaks even.
• Treating semi-fixed costs (a second machine at 2× volume) as flat across all quantities.
