Fixed Costs vs. Variable Costs
The foundation of break-even analysis is separating costs into two categories:
- Rent / mortgage
- Salaries and wages (fixed employees)
- Loan and lease payments
- Insurance premiums
- Subscriptions and software
- Utilities (base amount)
- Raw materials and supplies
- Direct production labor (hourly)
- Sales commissions
- Credit card processing fees
- Shipping and packaging
- Wholesale cost of inventory
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.
Contribution Margin Ratios by Industry
Understanding typical CM ratios in your industry helps you benchmark your own numbers.
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.
- Current revenue $75,000 / month and break-even at $45,000 = margin of safety of $30,000 (40%). Strong position.
- Current revenue $50,000 / month and break-even at $48,000 = margin of safety of $2,000 (4%). Fragile — any slowdown creates a loss.
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.
