Expense-to-revenue ratio calculator
Enter net revenue and operating expenses for the same period. Get the percentage instantly, see the OPEX formula, and understand what the result does—and does not—mean.
This is the overhead-only OPEX ratio. Keep cost of sales separate; the remainder is not a profit margin.
Use the same period and currency. Arabic and Western digits are supported. Starting values are illustrative, not customer data.
Expense-to-revenue ratio
75.0%
Most revenue is being consumed by operating expenses. Compare the ratio with budget and prior periods.
Revenue less operating expenses
25,000
This is not operating or net profit. If cost of sales is excluded, it must also be deducted, along with any other costs not entered.

Operating expenses ÷ Revenue × 100
Compare the ratio with budget, prior months, and the economics of your business. A lower ratio is not automatically better if spending supports profitable growth.

What to enter
Net revenue
Use revenue after discounts, returns, refunds, and other reductions when those fields are available. Keep the reporting period identical to the expense period.
Operating expenses
Enter the operating-cost categories included in your definition, such as payroll, rent, marketing, software, insurance, utilities, and administration. Apply the same definition every period.
Example: $45,000 of operating expenses divided by $75,000 of net revenue equals 60%. The calculation shows that the entered operating expenses consumed 60 cents of every revenue dollar.
How to interpret the result
| Result | What it indicates | What to check next |
|---|---|---|
| Above 100% | Entered expenses exceed revenue. | Cash impact, one-time costs, pricing, and the path to break-even. |
| 70% to 100% | Expenses consume most revenue. | Budget variance, gross margin, and whether spending is producing growth. |
| Below 70% | More revenue remains after entered expenses. | Whether all costs are complete and necessary investment is being maintained. |
These ranges are prompts for investigation, not industry benchmarks. For example, $75,000 of operating expenses divided by $100,000 of revenue produces a 75% ratio. The $25,000 remainder is not profit: any excluded cost of sales, financing, taxes, and other costs still need to be deducted.
For a prior-period ratio of 80% and a current ratio of 75%, the change is −5 percentage points, not −5%. Use the optional comparison in the calculator with the same cost definition and currency.
For the income-statement distinction between cost of sales, overhead, and profit, see the SEC financial-statement guide. This tool is educational and does not replace an accounting review.
Frequently asked questions
What is the expense-to-revenue ratio?
It is operating expenses divided by revenue for the same period, multiplied by 100. It shows how much revenue is consumed by the operating expenses entered.
What is a good expense-to-revenue ratio?
There is no universal target. Compare the result with your approved budget, prior periods, and businesses with a similar model. A lower ratio can be positive, but underinvestment can also reduce future growth.
Should cost of goods sold be included?
For the overhead-only OPEX ratio used here, keep cost of sales separate. If you include it, label the result a total expense-to-revenue ratio and keep that definition consistent. Revenue less overhead alone is not profit.
