Quick Answer

The break-even point is the level of sales at which your total revenue equals your total costs — neither profit nor loss. Above the break-even point, your business is profitable; below it, you're losing money. Break-even point in units = Fixed Costs ÷ (Unit Price − Variable Cost per Unit). Break-even in dollars = Fixed Costs ÷ Contribution Margin Ratio.

Understanding Break-Even Analysis

The Break-Even Formula

Break-Even Point in Units:

Break-Even Units = Fixed Costs ÷ (Unit Price − Variable Cost per Unit)

Break-Even Point in Revenue:

Break-Even Revenue = Fixed Costs ÷ Contribution Margin Ratio

Contribution Margin Ratio:

CM Ratio = (Unit Price − Variable Cost) ÷ Unit Price × 100

Margin of Safety:

Margin of Safety = Current Revenue − Break-Even Revenue

Fixed Costs vs. Variable Costs

The foundation of break-even analysis is separating costs into two categories:

Fixed Costs
Costs that stay constant regardless of how many units you sell. They're owed whether you sell 0 or 10,000 units.
  • Rent / mortgage
  • Salaries and wages (fixed employees)
  • Loan and lease payments
  • Insurance premiums
  • Subscriptions and software
  • Utilities (base amount)
Variable Costs
Costs that change directly with production or sales volume. They're zero if you sell nothing; they increase as sales increase.
  • Raw materials and supplies
  • Direct production labor (hourly)
  • Sales commissions
  • Credit card processing fees
  • Shipping and packaging
  • Wholesale cost of inventory
What about "semi-variable" costs? Some costs are partly fixed, partly variable — like utilities (base charge is fixed, usage charge is variable) or staffing (core team is fixed, overtime or temp labor is variable). For break-even analysis, split semi-variable costs: estimate the fixed portion and the variable cost per unit portion separately.

What is Contribution Margin?

Contribution margin is the amount each unit sold contributes toward covering fixed costs — after variable costs are paid. It's the revenue left over per unit to put toward profit.

If your unit price is $100 and variable cost per unit is $40, your contribution margin is $60. That means for every unit you sell, you put $60 toward fixed costs and (eventually) profit. Once fixed costs are fully covered, each unit sold generates $60 in pure profit.

How Lenders Use Break-Even Analysis

When you apply for an SBA loan, conventional business loan, or in some cases even an MCA, lenders evaluate whether your current revenue is above your break-even point — and by how much. This is your margin of safety.

Including a break-even analysis in your SBA loan application (in the financial projections section) demonstrates financial sophistication and gives lenders confidence that you understand your own economics.

Frequently Asked Questions

What is a break-even point?
The break-even point is the level of sales at which your total revenue exactly equals your total costs — no profit, no loss. Above the break-even point, the business is profitable. Below it, you're operating at a loss. Formula: Break-Even Units = Fixed Costs ÷ (Unit Price − Variable Cost per Unit).
What is contribution margin?
Contribution margin is the revenue remaining after variable costs are subtracted — the amount each unit sold "contributes" toward fixed costs and profit. Unit Contribution Margin = Selling Price − Variable Cost Per Unit. A contribution margin of $47 means each unit you sell puts $47 toward fixed costs and (once break-even is passed) profit.
What is margin of safety?
Margin of safety is the difference between your current revenue and your break-even revenue. It represents how much your revenue can drop before you start operating at a loss. A large margin of safety means your business is resilient to slow periods. Margin of Safety = Current Revenue − Break-Even Revenue. Margin of Safety % = (Current Revenue − Break-Even Revenue) ÷ Current Revenue × 100.
How do I use break-even analysis for pricing decisions?
Break-even analysis helps you understand the price floor — the minimum price at which a product or service is worth selling. If your variable cost per unit is $30 and fixed costs are $10,000/month, selling at $50/unit means you need to sell 500 units to break even. Selling at $60 means you only need 333 units to break even. Try adjusting price in the calculator above to see how pricing decisions affect your break-even point.
