Understanding companies
Profit is what remains after defined revenues and expenses are matched for an accounting period. Different profit measures stop at different layers, so the label needs a definition.

Start with a shop's sales and subtract the bills included in the question. What remains changes depending on whether the question stops after stock, operations, interest or tax.
Now put that into markets
Companies report gross, operating, pre-tax and net profit. Each measure answers a different question about the economics available at that stage.
Accounting profit includes non-cash items and recognition estimates. Net profit belongs after operating costs, financing, tax and other applicable items, while cash flow tracks actual cash movements.
Use a consistent profit definition across periods and companies. Inspect exceptional items, share-based compensation, depreciation, tax and the reconciliation of adjusted measures.
Profit is not cash in the bank and can be affected by estimates. A single period may also contain timing or one-off effects that do not describe sustainable earning power.
