Break-Even Calculator

What Is the Break-Even Point?

The break-even point is the level of sales at which total revenue exactly equals total costs — you are neither making a profit nor incurring a loss. It is the threshold your business must cross before it starts generating profit.

Break-even analysis is one of the most practical tools in business finance. It gives you a concrete, specific answer to the question: "How much do we need to sell just to survive?" Every unit sold above the break-even point contributes directly to profit. Every unit sold below it means you're still covering costs.

Understanding your break-even point is essential for setting sales targets, evaluating pricing decisions, assessing the viability of a new product, and understanding the impact of cost changes on your business.

How It Works

Enter three values:

• Total Fixed Costs: All costs that remain constant regardless of how many units you sell. This includes rent, salaries (of non-production staff), insurance, software subscriptions, loan repayments, and any other overhead that you pay whether you sell 0 units or 10,000 units. Use your total monthly fixed costs.
• Selling Price per Unit: The price you charge the customer for one unit of your product or service.
• Variable Cost per Unit: The direct cost to produce or deliver one unit. This includes raw materials, packaging, direct labour, payment processing fees, and any other cost that increases with each additional unit sold.

The calculator computes the contribution margin per unit (selling price minus variable cost), then divides total fixed costs by the contribution margin to find the break-even unit count. It also calculates the break-even revenue (units × selling price).

When to Use This Calculator

• When launching a new product or business — before you start, calculate the break-even point to understand the minimum viable sales volume and assess whether it's realistic
• When setting monthly sales targets — the break-even point is the floor for your sales target; anything above it is profit
• When evaluating a price change — if you raise or lower your price, the break-even point changes; use this calculator to model the impact before making the change
• When your costs change — if rent increases or a supplier raises prices, recalculate to see how many more units you need to sell to maintain the same profitability
• When considering a new overhead expense — before hiring a new employee or signing a lease, calculate how many additional units you need to sell to cover the new fixed cost
• When presenting to investors or lenders — break-even analysis is a standard component of any business plan or financial presentation

Common Mistakes

• Mixing up fixed and variable costs. Fixed costs are constant regardless of volume (rent, salaries). Variable costs change with each unit sold (materials, packaging). Putting a variable cost in the fixed cost field — or vice versa — will produce an incorrect break-even point. If you're unsure, ask: "Would this cost disappear if I sold zero units?" If yes, it's variable. If no, it's fixed.
• Forgetting some fixed costs. It's easy to remember rent but forget insurance, software subscriptions, loan repayments, or the cost of your own time. Make sure your fixed cost figure captures every recurring expense that exists regardless of sales volume.
• Using an average selling price when you sell multiple products. If you sell products at different price points, a single break-even calculation won't be accurate. Either calculate break-even separately for each product, or use a weighted average price and variable cost based on your expected sales mix.
• Treating break-even as the target. Break-even is the floor, not the goal. Your actual sales target should be significantly above break-even to generate meaningful profit. Use the break-even point as a minimum threshold, not a success metric.
• Not updating the calculation when things change. Break-even analysis is only useful if it reflects current costs and prices. Recalculate whenever there's a significant change in fixed costs, variable costs, or selling price.

How to Interpret Your Result

The break-even unit count tells you the minimum number of units you must sell each month to avoid a loss. Here's how to use the result:

• Compare to your current sales volume. If you're already selling well above break-even, your business is profitable at the gross level. If you're below break-even, you're currently losing money and need to either increase sales, reduce costs, or raise prices.
• Use it to set a realistic sales target. Your monthly sales target should be your break-even units plus enough additional units to generate your desired profit. For example, if break-even is 150 units and you want $5,000 profit at a $38 contribution margin, your target is 150 + 132 = 282 units.
• Assess the margin of safety. The margin of safety is how far your current sales are above break-even. A large margin of safety means your business can absorb a significant drop in sales before becoming unprofitable. A small margin of safety means you're vulnerable to any downturn.

Frequently Asked Questions

What is the difference between break-even units and break-even revenue?

Break-even units is the number of individual products or services you need to sell to cover all costs. Break-even revenue is the total sales value (in currency) needed to reach break-even. They are related: break-even revenue = break-even units × selling price. Both are useful — units is more actionable for production planning, while revenue is more useful for financial reporting and investor conversations.

What if I sell multiple products at different prices?

For a multi-product business, you have two options. First, calculate break-even separately for each product using its own price and variable cost. Second, calculate a blended break-even using a weighted average price and variable cost based on your expected sales mix. The second approach gives you a single break-even figure for the whole business, but it's only accurate if your actual sales mix matches your assumptions.

How does break-even analysis relate to profit margin?

They are complementary tools. Profit margin tells you how profitable each unit is relative to its selling price. Break-even analysis tells you how many units you need to sell to cover your fixed costs. A high profit margin means a lower break-even point (each unit covers more of your fixed costs). Use the Profit Margin Calculator alongside this one for a complete picture.

Can I use this for a service business?

Yes. For a service business, replace "units" with your billing unit — hours, projects, clients, or sessions. Your "selling price" is your rate per billing unit, and your "variable cost" is any direct cost associated with delivering that unit of service (subcontractors, materials, tools used per project). The formula works the same way.

What should I do if my break-even point seems unrealistically high?

If the break-even unit count is higher than you can realistically sell, you have three levers: raise your selling price (increases contribution margin), reduce variable costs (increases contribution margin), or reduce fixed costs (lowers the total that needs to be covered). Often a combination of all three is needed. The Pricing Calculator can help you model the impact of price changes on your required sales volume.
