Operating Profit (EBIT)
Profit left after operating expenses, before interest and tax. Measures whether the core business works.
Definition
Operating profit, also called EBIT (Earnings Before Interest and Tax), is what remains after subtracting COGS and all operating expenses (payroll, rent, marketing, licensing, insurance, depreciation) from revenue. It excludes financing costs and tax. It matters because it shows whether the core business is profitable, independent of debt structure or tax rate. Two companies can post the same net profit while one is operationally healthy and the other relies on debt or tax shields. Negative operating profit with positive gross margin signals bloated overhead. EBIT is the foundation for EBITDA and most valuation models.
What sits inside operating expenses
Operating expenses (OpEx) sit between gross profit and operating profit. They include payroll for non-delivery roles (admin, founder, ops), office rent or coworking, software subscriptions not tied to client delivery, marketing spend, professional fees (legal, accounting), insurance, utilities, and depreciation. For a typical US LLC service business, payroll is 50 to 70 percent of OpEx and SaaS subscriptions are the second-largest bucket and the most ignored. Run a SaaS audit every quarter: most founders find 200 to 500 dollars per month of forgotten subscriptions. Operating expenses are where bloat hides because each line looks small individually but the total quietly eats the gross profit you fought to earn.
Operating margin benchmarks
Operating margin (operating profit divided by revenue) varies sharply by stage and sector. Early-stage US service businesses under 1M ARR often run 5 to 15 percent operating margin while they invest in growth. Mature service firms hit 20 to 30 percent. SaaS at scale targets 20 to 25 percent operating margin or higher. If you are above 30 percent and growing slowly, you are likely under-investing in growth. If you are negative and revenue is flat, OpEx is structurally too high. The combination of operating margin plus growth rate (the Rule of 40 in SaaS) is the single best one-glance health check for a software business and a useful frame for service businesses too.
EBIT versus operating profit
Operating profit and EBIT (Earnings Before Interest and Tax) are almost identical in US GAAP, with one subtle difference: operating profit comes from the income statement structure and includes only operating items, while EBIT can include non-operating gains (like sale of an asset). For a small US business, treat them as the same number. EBIT is the cleaner metric for comparing two companies because it removes financing structure (interest) and tax jurisdiction differences. If you ever talk to an SBA lender, a potential buyer, or a PE firm, they will anchor on EBIT or EBITDA, not net profit.
How to defend operating margin in a downturn
When revenue softens, operating margin collapses faster than founders expect because most OpEx is fixed in the short term. The defense order: cut discretionary marketing first (it can be turned back on in days), then non-essential SaaS, then contractor hours, then renegotiate lease and big vendor contracts, then payroll as last resort. Avoid across-the-board cuts; instead, kill bottom-quartile spend per line. A useful rule: for every 10 percent revenue drop you forecast, identify 15 percent of OpEx you can pull within 60 days. The 5 percent buffer is what keeps you out of layoffs.
FAQ
Is owner salary part of operating expenses?
Yes, in a properly-structured P&L. If you run an S-Corp in the US, the IRS requires reasonable compensation paid as W-2 wages, which lands in OpEx. If you are a sole proprietor or single-member LLC taxed as a disregarded entity, owner draws are not on the P&L at all, which inflates operating profit and makes the business look more profitable than it really is. To compare cleanly with peers, impute a market-rate salary for yourself and subtract it from operating profit before judging health.
What is a healthy operating margin for a US consulting firm?
Mature US consulting firms (10+ years, 2M+ revenue) typically run 15 to 25 percent operating margin. Boutique high-end firms can hit 30 to 40 percent. Below 10 percent for a mature firm usually signals one of three problems: underpriced engagements, over-staffing relative to billable utilization, or excessive overhead (especially office and BD spend). Track utilization rate (billable hours divided by available hours) alongside operating margin; 65 to 75 percent utilization is healthy for senior consultants.
Should depreciation reduce operating profit?
Yes under GAAP and IRS accounting. Depreciation is a non-cash expense but it reflects real economic wear on capital assets and reduces operating profit. This is why EBITDA (which adds depreciation back) became popular for capital-intensive businesses. For a typical US service business with limited fixed assets (laptops, office furniture), depreciation is small and the operating profit versus EBITDA gap is negligible. For a manufacturer or e-commerce business with inventory and warehouse equipment, the gap can be material.
Operating profit is positive but I have no cash. Why?
Operating profit is an accrual concept; cash is timing. The gap usually comes from: accounts receivable (you booked revenue clients have not paid), inventory tying up cash, prepaid expenses (annual SaaS contracts paid upfront), or principal repayments on loans (interest is in OpEx but principal is not). Build a 13-week cash flow forecast next to your P&L to see the gap. Profitable businesses go bankrupt every year because they ignored this distinction.
How does operating profit get used in business valuation?
Most US small-business valuations use a multiple of EBITDA or SDE (Seller's Discretionary Earnings, which is EBITDA plus owner add-backs). Multiples range from 2x to 6x for service businesses under 5M revenue, 4x to 10x for software, depending on growth, recurring revenue mix, and customer concentration. Operating profit per se is rarely the headline number, but it is the foundation: investors first verify operating profit is real, then apply add-backs to get to SDE or adjusted EBITDA.
