What this specific question is asking

Treat the output as a consequence of the setup. For this query the setup is revenue, cost of goods sold (cogs) and operating expenses — verify each for unit, period and meaning, then let Profit and Loss Calculator do the arithmetic.

A fast validation: take the worked example (As a worked reference for “Difference between income and revenue and…), swap in your own revenue, and confirm the result shifts in the direction the relationship predicts. If it moves the wrong way, recheck the units before the math.

Inputs to verify

Verify revenue before calculation; if this value uses a different unit, period or definition, convert or restate it first.
Verify cost of goods sold (cogs) before calculation; if this value uses a different unit, period or definition, convert or restate it first.
Verify operating expenses before calculation; if this value uses a different unit, period or definition, convert or restate it first.

Step-by-step check

Enter total revenue for the period.
Enter the cost of goods sold (COGS).
Enter operating expenses, or leave them at zero.
Tap Calculate to see gross profit, net profit or loss, and margin.

Worked example and sanity check

As a worked reference for “Difference between income and revenue and profit”, Worked example Buying at 800 and selling at 1,000: profit 200, so profit% = 200 ÷ 800 × 100 = 25% .

Interpreting the result

So what does the number mean? In the worked example the calculation produced 200 ÷ 800 × 100 = 25%. A result in that range is plausible for this kind of input; if your result lands far from it, revisit revenue first — it is the input most often entered on the wrong basis. Read the magnitude before the decimals: a result ten times too large or small almost always means a unit or period slipped, not that the formula failed.
