Frequently asked questions
What counts as a fixed cost?
Costs that do not change with output: rent, insurance, salaries, subscriptions, loan payments.
What is contribution margin?
Selling price minus variable cost per unit. It is the amount each unit "contributes" toward covering fixed costs and then profit.
Can I use this for services?
Yes. Treat each billable hour or project as a "unit". Your hourly rate is the price; direct labour and materials are the variable cost.
