How to Use This Break-Even Point Calculator
- Fixed Costs: Enter your total monthly fixed costs — expenses that don’t change with sales volume, such as rent, salaries, and software subscriptions.
- Variable Cost per Unit: Enter the direct cost to produce or deliver one unit — materials, packaging, and direct labour per item.
- Selling Price per Unit: Enter the price at which you sell one unit to your customer.
- Quantity Sold (optional): Enter how many units you expect to sell to see your projected profit or loss at that volume.

How to Interpret Your Results
Above Break-Even
In profit. Every unit sold beyond your break-even point adds pure contribution margin to your bottom line. The further above break-even, the healthier your business.
At Break-Even
Covered, not profitable. Total revenue exactly equals total costs. You haven’t lost money, but you haven’t made any profit yet either.
Below Break-Even
Operating at a loss. Revenue is not covering costs. You need to either increase sales, raise your price, or reduce costs to reach break-even.
What is a Break-Even Point?
The break-even point is one of the most fundamental numbers in business. It tells you the exact number of units you must sell — or the exact amount of revenue you must generate — to cover all of your costs. Before this point you are making a loss on every period; at this point you break even; beyond it every additional sale generates profit.
Understanding your break-even point is essential for pricing decisions, launch planning, fundraising conversations, and general financial management. It answers one of the most important questions any business owner can ask: “How much do I need to sell just to stay afloat?”
Real-World Example — Coffee Stand
You want to open a coffee stand at a local market. Here are your numbers:
Fixed Costs (stall rent + equipment): £1,000 / month
Variable Cost per Cup (coffee + milk + cup): £0.50
Selling Price per Cup: £2.50
Contribution Margin: £2.50 − £0.50 = £2.00 per cup
Break-Even Point: £1,000 ÷ £2.00 = 500 cups
You must sell 500 cups per month just to cover your costs. Cup number 501 is your first cup of pure profit — at £2.00 contribution per cup. Sell 700 cups and you make £400 profit. Sell only 400 and you lose £200.
The Break-Even Formula
Contribution Margin =
Selling Price − Variable Cost
Break-Even (units) =
Fixed Costs ÷ Contribution Margin
Break-Even (revenue) =
Break-Even Units × Selling Price
Key Terms Explained
Fixed Costs
Costs that don’t change regardless of how many units you sell — rent, salaries, insurance, software subscriptions.
Variable Costs
Costs that increase directly with each unit sold — materials, packaging, direct labour, fulfilment.
Contribution Margin
The amount each unit sold contributes to covering fixed costs. Once fixed costs are covered, contribution margin becomes profit.
How to Lower Your Break-Even Point
A lower break-even point means you reach profitability with fewer sales — giving you more resilience and faster returns. There are three ways to achieve it:
1. Reduce Fixed Costs
- → Negotiate cheaper rent or go remote
- → Cancel underused subscriptions
- → Hire freelancers vs. full-time staff
- → Share office or warehouse space
2. Reduce Variable Costs
- → Negotiate better supplier rates
- → Buy materials in larger volumes
- → Reduce packaging complexity
- → Improve production efficiency
3. Increase Selling Price
- → Test a 5–10% price increase
- → Improve perceived value or branding
- → Target higher-value customer segments
- → Add premium product tiers
Break-Even Analysis: When to Use It
Break-even analysis is useful at every stage of a business, not just at launch. Here are the most common situations where it adds real value:
- →Launching a new product or service — before investing time and money, confirm your pricing model is viable.
- →Setting sales targets — give your team a clear minimum target before commissions or bonuses kick in.
- →Evaluating a price change — understand how a price increase or decrease shifts the number of units you need to sell.
- →Raising investment or applying for a loan — investors and banks want to see a credible path to profitability.
- →Assessing the impact of higher costs — if rent or supplier costs rise, recalculate to understand the new sales target required.
Frequently Asked Questions
What is a break-even point calculator?
A break-even point calculator helps you find the exact number of units you need to sell — or the revenue you need to generate — to cover all your costs. You enter your fixed costs, variable cost per unit, and selling price, and the calculator works out your break-even point, contribution margin, and projected profit or loss at any sales volume.
How do I calculate break-even point?
The formula is: Break-Even Units = Fixed Costs ÷ Contribution Margin per Unit. Contribution margin = Selling Price minus Variable Cost per Unit. For example: fixed costs £1,000, selling price £10, variable cost £4 → contribution margin £6 → break-even = 167 units.
What is a contribution margin?
The contribution margin is the amount each unit sold contributes to covering your fixed costs after variable costs are deducted. It is your selling price minus your variable cost per unit. Once you’ve sold enough units to cover all fixed costs, the contribution margin from each additional sale becomes pure profit.
Why is my break-even point showing as “not achievable”?
This happens when your variable cost per unit is greater than or equal to your selling price. Your contribution margin is zero or negative, meaning you lose money on every sale regardless of volume. You must increase your selling price or reduce variable costs to create a positive contribution margin.
How can I lower my break-even point?
There are three levers: reduce fixed costs (e.g. cheaper premises, cancel unused subscriptions), reduce variable costs per unit (e.g. negotiate better supplier rates, buy in bulk), or increase your selling price. A lower break-even point means you reach profitability sooner and have greater resilience to slow sales periods.
