Whether you’re launching a new product, reviewing your pricing strategy, or seeking funding, knowing the moment your business starts to cover its costs is essential.

In this guide, we explain what the break-even point is, how to calculate it, and why it’s a valuable tool for pricing, budgeting, and strategic decision-making.

What Is a Break-Even Point?

The break-even point is the moment at which your total revenue equals your total costs. At this point, your business is not making a profit, but it’s also not making a loss.

Everything you earn beyond the break-even point becomes profit, while anything below it is a loss. It’s a vital benchmark for any small business and is used to:

  • Determine pricing
  • Control fixed and variable costs
  • Forecast sales targets
  • Support business planning and funding

Why the Break-Even Point Matters

Calculating and regularly reviewing your break-even point can help with:

  1. Pricing Strategy

Understanding how much you need to sell to cover costs helps inform pricing decisions. It ensures you don’t underprice your product or service and fall short of profitability.

  1. Cost Control

By breaking down fixed and variable costs, you gain better insight into which areas you can optimise, reducing your break-even point and improving profitability.

  1. Sales Forecasting

Knowing your break-even sales volume helps set realistic sales targets and performance expectations, especially during growth or new product launches.

  1. Financial Planning

If you’re applying for funding or creating a business plan, lenders and investors will often ask for a break-even analysis to assess the risk and scalability of your business.

Key Terms to Know

Before calculating your break-even point, it’s important to understand the two types of costs:

Fixed Costs

These are costs that stay the same regardless of how much you sell. Examples include:

  • Rent or mortgage for your office or premises
  • Staff salaries (excluding bonuses or commissions)
  • Business insurance
  • Subscriptions (e.g. software tools)
  • Depreciation

Variable Costs

These change in direct proportion to your level of output or sales. Examples include:

  • Materials or product stock
  • Shipping and packaging
  • Commissions
  • Hourly wages or freelancer fees
  • Utility costs linked to production

How to Calculate Your Break-Even Point

The basic formula for the break-even point in units is:

Break-Even Point (Units) = Fixed Costs ÷ (Selling Price per Unit – Variable Cost per Unit)

This formula tells you how many units you need to sell to break even.

Example:

Let’s say you run a business selling custom-made notebooks:

  • Fixed costs: £10,000 (per year)
  • Selling price per notebook: £20
  • Variable cost per notebook: £8

Using the formula:

Break-Even Units = £10,000 ÷ (£20 – £8)
Break-Even Units = £10,000 ÷ £12
Break-Even Units = 834 notebooks (rounded)

You’d need to sell at least 834 notebooks just to cover your costs.

Break-Even Point in Revenue

You can also calculate your break-even point in sales revenue:

Break-Even Revenue = Break-Even Units × Selling Price

Using the example above:

834 notebooks × £20 = £16,680

So, you need £16,680 in revenue to break even.

Adding a Target Profit

To factor in a desired profit target, adjust the formula:

Target Break-Even Units = (Fixed Costs + Target Profit) ÷ Contribution Margin

Let’s say you want a £5,000 profit on top of covering your costs:

Target Break-Even Units = (£10,000 + £5,000) ÷ £12 = 1,250 units

This version of the formula is useful for financial forecasting and growth planning.

Tools to Help You

You can calculate your break-even point using:

  • A spreadsheet (e.g. Excel or Google Sheets)
  • Online calculators like Break-Even Calculator – Zoho.com
  • Accounting software with forecasting tools (e.g. Xero, QuickBooks, or The Balance App)

If you’re unsure how to build a model, your accountant can help set up a custom break-even calculator based on your business structure.

Common Mistakes to Avoid

  1. Ignoring Seasonal Fluctuations
    Businesses with seasonal income should adjust fixed and variable costs for peak and off-peak periods. A single annualised figure may not reflect real-world performance.
  2. Underestimating Variable Costs
    Failing to account for costs like packaging, transaction fees, or marketing per unit can lead to underpriced products and inaccurate break-even points.
  3. Not Reviewing Regularly
    Your break-even point can change as prices, costs, and sales strategies evolve. Regularly updating your figures ensures you’re working with accurate benchmarks.

How Break-Even Analysis Supports Business Strategy

Break-even analysis is more than just a finance exercise. It influences several key strategic areas:

  1. Product Decisions
    Should you launch a new service? Can you afford to discount products? Knowing the sales needed to break even on a new line can help you decide.
  1. Growth Planning
    Looking to expand or take on new staff? A break-even model can help you assess if projected income will cover the increase in overheads.
  1. Cost Reduction Initiatives
    If your break-even point is too high, it can reveal inefficiencies in your cost base, especially in fixed overheads or supplier pricing.

Break-Even Point vs. Cash Flow

It’s important to note that your break-even point shows profitability, not cash flow. A business can be profitable on paper but still face cash flow issues due to delayed payments or upfront cost requirements.

Make sure to:

  • Pair break-even analysis with cash flow forecasting
  • Monitor working capital and liquidity alongside profit margins
  • Maintain sufficient reserves or credit lines to handle short-term gaps

Final Thoughts on Calculating your Break-Even Point

Knowing how to calculate your break-even point gives you a clearer picture of your business’s financial health and the sales targets you need to hit. It’s a simple, yet powerful tool that can guide pricing, control costs, support funding bids, and inform key decisions.

Whether you’re planning a launch, reviewing your costs, or seeking investment, break-even analysis should be part of your financial toolkit.
