What counts as a fixed cost?

Fixed costs remain constant regardless of production volume: rent, insurance, salaries, equipment leases, and loan payments. These costs exist even if you sell zero units.

What are variable costs?

Variable costs change with production volume: raw materials, packaging, shipping, sales commissions, and direct labor per unit. More units produced means higher total variable costs.

How do I lower my break-even point?

Reduce fixed costs, lower variable costs per unit, or increase your selling price. Each approach changes the equation: fewer fixed costs to cover, or more contribution per unit to cover them faster.

Does break-even analysis work for service businesses?

Yes. Instead of units, use billable hours or client engagements. Your fixed costs are overhead, variable costs are time and materials per engagement, and revenue is your hourly rate or project fee.

What is a margin of safety?

Margin of safety is how far your actual sales exceed the break-even point. If you break even at 1,000 units and sell 1,500, your margin of safety is 500 units or 33%. Higher margins of safety indicate lower business risk.

What Is Break-Even Analysis?

Break-even analysis is one of the most fundamental tools in business planning. It tells you the exact sales volume at which your total revenue equals your total costs — meaning you're neither losing money nor making a profit. Every sale above that point contributes directly to your bottom line. Whether you're launching a product, opening a storefront, or pricing a service, knowing your break-even point is the first step toward making confident financial decisions.

The analysis separates your costs into two categories: fixed costs, which stay the same regardless of how much you produce (rent, salaries, insurance), and variable costs, which rise in proportion to output (materials, packaging, transaction fees). Understanding both is essential. A business with high fixed costs needs high volume to survive, while one with high variable costs can stay lean but struggles to scale profit. Break-even analysis makes these dynamics visible before you commit real money.

1Enter your total monthly or annual fixed costs — all expenses that don't change with sales volume, such as rent, utilities, and salaried staff.
2Enter your variable cost per unit — the direct cost to produce or deliver one unit, including materials, labor, and transaction fees.
3Enter your selling price per unit — the price a customer pays for one unit of your product or service.
4Click Calculate to instantly see your break-even units (how many you must sell) and break-even revenue (the total sales dollars needed to cover all costs).

Break-Even Formulas

Break-Even Units   = Fixed Costs / (Selling Price − Variable Cost per Unit)
Contribution Margin = Selling Price − Variable Cost per Unit
Break-Even Revenue  = Break-Even Units × Selling Price

The contribution margin is the key metric here — it represents how much each unit sale contributes toward covering your fixed costs after paying for its own variable costs. A higher contribution margin means you reach break-even faster and earn profit sooner. The contribution margin ratio (contribution margin ÷ selling price) tells you what percentage of every dollar of revenue flows toward fixed cost recovery and profit.

Real-World Examples

Coffee Shop

Fixed costs: $8,000/month (rent, equipment lease, staff). Variable cost per cup: $1.20 (beans, milk, cup, lid). Selling price: $4.50. Contribution margin = $4.50 − $1.20 = $3.30 per cup. Break-even = $8,000 ÷ $3.30 = 2,424 cups per month. That's about 81 cups per day — a very achievable target for a busy café, and every cup sold after that is pure profit contribution.

Software Product

Fixed costs: $50,000/month (engineering salaries, hosting, SaaS tools). Variable cost per unit: $5 (payment processing, onboarding support). Selling price: $99/month per seat. Contribution margin = $99 − $5 = $94 per seat. Break-even = $50,000 ÷ $94 = 533 seats. Once you cross 533 active subscriptions, your software business is profitable — and because variable costs are low, each new customer is almost entirely margin.

Restaurant

Fixed costs: $15,000/month (lease, kitchen staff, insurance). Average variable cost per meal: $12 (food, disposables, server labor per cover). Average selling price per meal: $35. Contribution margin = $35 − $12 = $23 per meal. Break-even = $15,000 ÷ $23 = 653 meals per month. That's roughly 22 covers per day — a useful benchmark when evaluating whether a new location or menu change will be financially viable.

Frequently Asked Questions

What is the difference between fixed costs and variable costs?▾

Fixed costs remain constant regardless of how many units you produce or sell — examples include rent, insurance premiums, annual software licenses, and salaried employees. Variable costs change directly with output — think raw materials, hourly labor, shipping per order, and payment processing fees. The distinction matters because fixed costs create the 'floor' you must cover before any profit is possible, while variable costs determine how much of each sale you actually keep.

What is the contribution margin ratio and how do I use it?▾

The contribution margin ratio is the contribution margin expressed as a percentage of the selling price: (Selling Price − Variable Cost) ÷ Selling Price. For example, if you sell at $100 and variable costs are $30, your contribution margin ratio is 70%. This means 70 cents of every dollar of revenue goes toward covering fixed costs and generating profit. It's especially useful for comparing the profitability of different products and for calculating break-even revenue directly: Break-Even Revenue = Fixed Costs ÷ Contribution Margin Ratio.

How does break-even analysis help with pricing decisions?▾

Break-even analysis immediately shows the impact of a price change. If you lower your price, the contribution margin shrinks and you need to sell more units to cover the same fixed costs — sometimes dramatically more. If you raise your price and demand holds, the margin expands and break-even falls. Running the calculator at two or three price points side-by-side is one of the fastest ways to evaluate a pricing strategy before you commit to it in the market.

Can I use break-even analysis when I sell multiple products?▾

Yes, though it requires a weighted average approach. Calculate the contribution margin for each product, then weight it by that product's share of total sales (the sales mix). For example, if 60% of your sales are Product A with a $20 margin and 40% are Product B with a $10 margin, your weighted average contribution margin is (0.6 × $20) + (0.4 × $10) = $16. Divide your total fixed costs by $16 to get the break-even unit volume across the mix. Keep in mind that if your sales mix shifts, your break-even point shifts too.

What should I do if my break-even point seems too high to reach?▾

A high break-even point is a signal, not a verdict. You have several levers: raise your selling price (even a small increase can significantly lower break-even), reduce variable costs by renegotiating supplier contracts or finding more efficient processes, or cut fixed costs by downsizing space, outsourcing, or deferring non-essential expenses. Sometimes the right answer is to reconsider the business model entirely — for example, switching from physical to digital delivery eliminates many variable costs and dramatically improves margins.
