Fixed Costs
Last reviewed 2026-05-11 by Asad Ali, Founder & CEO
Expenses that remain constant regardless of production.
Fixed costs do not change with production volume or sales activity within a relevant range. Common fixed costs include rent, property taxes, base insurance premiums, salaried wages and base payroll taxes, loan principal and interest payments, fixed-rate software subscriptions, equipment depreciation, and management compensation. They are sometimes called "committed costs" because they reflect prior decisions hard to reverse quickly. While fixed costs provide stability and predictability, they also create operating leverage — a high fixed-cost structure means profits scale rapidly with revenue growth but losses scale just as fast in downturns. Some costs are "stepped fixed" (a second shift supervisor, an additional office) that step up at specific activity thresholds, and "discretionary fixed" (advertising, R&D) that management can cut more easily than rent or salaries.
Formula
Total Fixed Costs = Rent + Insurance + Salaried Wages + Loan Payments + Depreciation + Fixed Subscriptions + Other Period Costs Independent of Volume. Break-even Units = Fixed Costs ÷ (Price per Unit − Variable Cost per Unit)Example
A hair salon's monthly fixed costs are $3,000 rent, $500 business insurance, $1,200 in software subscriptions (booking, payroll, accounting), $2,500 in salaried receptionist pay, $400 utilities base, and $600 in equipment depreciation. Total fixed costs = $3,000 + $500 + $1,200 + $2,500 + $400 + $600 = $8,200/month. Whether the salon serves 100 or 300 clients, that $8,200 still hits the P&L. With an average client revenue of $80 and variable cost of $20, contribution margin is $60 per client. Break-even = $8,200 ÷ $60 = 137 clients per month.
Why It Matters for Your Business
Fixed costs determine the minimum revenue needed to keep the lights on, making them the foundation of break-even analysis and survival planning.
Practical Tips
- •List every fixed cost annually and ask "could this be variable instead?" — moving rent to revenue-share or salaries to part-time/contract converts fixed risk into variable flexibility
- •Run sensitivity analysis: at what revenue level do you cover fixed costs? Every business owner should know this number to the dollar
- •Reduce stepped fixed costs first when scaling down — let one role attrit rather than across-the-board cuts that hurt morale
- •Track fixed-cost coverage ratio (Gross Profit ÷ Fixed Costs) monthly — staying above 1.0 means you are at least covering the lights
Common Questions About Fixed Costs
How is fixed costs calculated?
The formula is: Total Fixed Costs = Rent + Insurance + Salaried Wages + Loan Payments + Depreciation + Fixed Subscriptions + Other Period Costs Independent of Volume. Break-even Units = Fixed Costs ÷ (Price per Unit − Variable Cost per Unit). See the worked example below for a step-by-step calculation using realistic numbers.
