## Article

You know the product cost. You guessed a price. Ads, software, and studio rent still sit there every month whether you sell one unit or a hundred. The question that actually matters is: how many units to break even before you call it a win?

A break even calculator turns that from a gut feel into a number you can defend on a pricing call.

## The formula (contribution margin)

Break-even units = Fixed costs ÷ (Selling price − Variable cost per unit)

Selling price minus variable cost is contribution margin — what each sale contributes toward covering the bills that do not move with volume.

Example: £2,400/month fixed costs. Product sells at £40. Variable cost (COGS, packing, payment fees you treat as per-unit) is £16. Contribution = £24. Break-even = 2,400 ÷ 24 = 100 units per month.

Sell 99 and you are still funding the business out of pocket. Sell 101 and you start covering more than the floor.

## What counts as fixed vs variable

- Fixed: rent, salaried help, software subscriptions, insurance, a retainer photographer — costs that show up even at zero sales.

- Variable: materials, packing, shipping you pay per order, marketplace fees you model per unit, contractor time tied to each job.

If a cost scales with each extra sale, put it in variable. If it sits there anyway, put it in fixed. Mixing them inflates or hides the unit target.

## Calculate it without a spreadsheet

Open the free [BryteTools Break-even Calculator](https://brytetools.com/tools/break-even-calculator). Enter fixed costs, selling price, and variable cost per unit. You get the unit count immediately. It runs in the browser — no account, nothing stored.

Price still fuzzy? Check [Profit Margin Calculator](https://brytetools.com/tools/profit-margin-calculator) and [Markup ↔ Margin Converter](https://brytetools.com/tools/markup-margin-converter) so the selling price you plug in is a real margin, not a round number that feels safe.

## Worked scenarios

BusinessFixed / monthPriceVariableUnits to break even

Etsy prints£600£18£650

DTC skincare£3,200£28£9169

Freelance package£1,500£750£503 (projects)

The freelance row is the same math with “units” as projects. If you cannot hit three paid packages after overhead, the offer is underpriced or fixed costs are too high for the pipeline you actually have.

## Mistakes that hide a loss

- Ignoring your own time. If you would hire someone to pack orders, that labour is a cost. Unpaid founder hours make break-even look prettier than cashflow.

- Using list price, not net. Discounts, returns, and platform fees shrink contribution. Model the price you actually keep. Pair this with [Platform Fee Calculator](https://brytetools.com/tools/platform-fee-calculator).

- Price below variable cost. There is no break-even. Every extra unit loses more money. Raise price or cut variable cost first.

- Annual costs forgotten. Insurance and software annuals still belong in the monthly fixed pile (divide by 12).

## FAQ

What is a break-even point?The volume where total revenue equals total costs — zero profit, zero loss. Above it, contribution starts funding profit (and tax, and buffer).

Does this include VAT?Enter numbers the way you manage the business. Keep VAT consistent: all inclusive or all exclusive. For UK VAT math, use [VAT Calculator](https://brytetools.com/tools/vat-calculator).

Why won’t the calculator return a number?Selling price must be higher than variable cost. If it is not, you cannot break even at any volume.

Is this financial advice?No. It is unit economics. Confirm with your accountant for tax and cash timing.

Can I use it for services?Yes. Treat a package or retainers as the “unit” and put delivery cost in variable.
