Free Break-Even Calculator (Excel)

Your break-even point is the exact number of units you need to sell before you stop losing money. This free calculator does the math for you — enter your fixed costs, price per unit, and variable cost per unit, and it instantly shows how many units and how much revenue you need to break even.

Why use a template instead of starting from scratch?

It's tempting to just pick a price that feels right and see what happens. The problem is you won't know you priced it wrong until you're already deep into a slow, unprofitable sales cycle. Running the break-even numbers first — before you launch or change a price — takes ten minutes and can save months of selling at a loss.

How to Use This Template

Download and open in Excel or Google Sheets

Works identically in either — no macros or add-ins needed.

Enter your total fixed costs for the period

Rent, salaries, insurance — costs that don't change no matter how much you sell.

Enter your price per unit and variable cost per unit

Variable cost is what it costs you to produce or deliver one more unit — materials, direct labor, shipping.

Read your break-even point

The calculator shows exactly how many units, and how much revenue, you need before you start making a profit.

Run the built-in AI prompt to pressure-test it

Attach the saved file to ChatGPT or Claude and ask what happens if your fixed costs or price change.

Built-in AI prompt

Once you've filled this template in, it includes a ready-to-use prompt at the bottom of the sheet. Attach your saved file to ChatGPT, Claude, or any AI chat tool and paste it in — you'll get plain-English feedback on whether your break-even point is realistic given your market, and what happens if your assumptions are off, no accounting background required.

Common Mistakes to Avoid

Underestimating fixed costs

It's easy to leave out things that don't feel like 'real' expenses yet — your own time, software subscriptions, insurance. Include everything that doesn't change with volume.

Guessing at variable cost instead of calculating it

Treating variable cost as a rough guess instead of a real per-unit calculation lets small errors compound fast at higher volume.

Not checking the result against real market demand

The math can be correct and the plan can still fail if the break-even volume isn't realistic for what your market will actually buy.

Running it once and never again

Fixed costs, prices, and variable costs all drift over time. Recheck the calculation whenever any of them change materially.

Frequently Asked Questions

What is a break-even point?

It's the exact sales volume where your total revenue equals your total costs — no profit, no loss. Sell more than that, and you're profitable. Sell less, and you're losing money.

What's the difference between fixed and variable costs?

Fixed costs stay the same regardless of how much you sell — rent, salaries, insurance. Variable costs change with each unit you sell or produce — materials, direct labor, shipping. Break-even analysis needs both.

Why does break-even analysis matter before I set a price?

If your price is too close to your variable cost, you'd need to sell an unrealistic volume just to cover fixed costs. Running the numbers before you launch — not after — is what catches a pricing mistake early.

Is this template really free?

Yes, completely free, no email required. iLuvAccounting also has a paid Tools Club with 70+ templates and calculators if you want the full library.

What if my break-even point is higher than I can realistically sell?

That's exactly what this calculator is for — catching that before you launch, not after. Your options are usually to raise the price, reduce variable cost, cut fixed costs, or plan for a longer runway to profitability.

Does break-even analysis account for taxes?

No — this is a pre-tax operating break-even. It tells you when revenue covers costs, not your final after-tax profit.

How is contribution margin different from gross margin?

Contribution margin (price minus variable cost, per unit) is used specifically for break-even and volume decisions. Gross margin (revenue minus COGS, from your P&L) is a broader profitability measure. They're related but answer different questions.
