The income statement is built around a simple split: costs that come from running the business, and costs that come from how the business is financed and structured. Operating expenses fall in the first bucket; non-operating expenses fall in the second. Understanding the difference is the first step in reading any P&L meaningfully.
Where each appears on the income statement
The typical subscription business P&L flows like this:
- Revenue
- Less: Cost of Goods Sold
- = Gross Profit
- Less: Operating Expenses (salaries, marketing, software, fulfillment overhead)
- = Operating Income (also called EBIT)
- Less: Non-Operating Expenses (interest, taxes, FX losses, one-time charges)
- = Net Income
What goes where: subscription-business examples
- Customer support team salary → Operating expense
- Shopify monthly subscription → Operating expense
- Warehouse rent → Operating expense
- Paid ad spend → Operating expense
- Interest on a working-capital loan → Non-operating expense
- Federal income tax → Non-operating expense
- Loss on selling old fulfillment equipment → Non-operating expense
- One-time legal settlement → Non-operating expense
Why the distinction matters
Two reasons. First, comparability: two subscription businesses with the same operating performance but different debt loads will have different bottom lines entirely because of interest expense. Pulling non-operating items into a separate section lets you compare apples to apples. Second, decision relevance: operating expenses are the levers an operating team controls. Non-operating expenses are mostly the consequence of past financing and structural decisions made by finance and the board.
EBITDA: the operations-only view
EBITDA (earnings before interest, taxes, depreciation, and amortization) is a popular metric because it strips out almost everything non-operational plus the non-cash depreciation charge. It is widely used as a valuation shorthand for subscription businesses. Useful — but it does not replace looking at the full P&L, because depreciation reflects real economic costs of assets, even if not cash today.
