See how much of your revenue you actually keep after direct costs, overhead, and everything else.
Who this is for
Small business owners who want to know whether enough money is left after costs and overhead.
What to type in
Your revenue, direct costs, operating costs, and any other costs you want to count.
Start with the assumptions, then use the interpretation below to compare tradeoffs without bouncing between sections.
Add the money coming in and the main buckets of money going out.
Use these inputs as a quick setup row. The answer and visual breakdown sit below so you do not lose context.
Your total sales for the period.
The cost to make, buy, or deliver what you sold.
Payroll, rent, software, and other day-to-day business costs.
Anything else that reduces profit, like interest or taxes.
Healthy margin
On $500,000.00 in revenue, direct costs and operating expenses are leaving you with 25.0% net margin.
Gross margin is 60.0%, which tells you how much room you have before overhead.
Operating margin is 30.0% after running costs like payroll, rent, and software.
You are spending $200,000.00 on direct costs and $150,000.00 on overhead.
Keep tracking whether overhead is growing slower than revenue. That is what protects margin.
Use this with break-even if you want to turn the margin math into a sales target.
