What this specific question is asking
Before running Markup Calculator, write down what cost price and selling price mean for your case — including each unit and time period. The calculator multiplies whatever it is given; the setup decides whether the answer is usable.
Use the example (As a worked reference for “Gross margin markup”, Worked example A…) as a calibration run: reproduce it first, then change only cost price. The output should track the change predictably; if it does not, the inputs are on mismatched bases.
Inputs to verify
- Verify cost price before calculation; if this value uses a different unit, period or definition, convert or restate it first.
- Verify selling price before calculation; if this value uses a different unit, period or definition, convert or restate it first.
Step-by-step check
- Enter the cost price of the item.
- Enter the selling price you charge.
- Make sure the selling price is above the cost.
- Tap Calculate to see markup percent, margin, and profit.
Worked example and sanity check
As a worked reference for “Gross margin markup”, Worked example A product costing 200 sold at 260: markup = (260 − 200) ÷ 200 × 100 = 30% .
Interpreting the result
Interpretation starts with magnitude. The worked example landed at (260 − 200) ÷ 200 × 100 = 30%; compare yours before trusting the decimals. If the two disagree wildly, the setup — usually cost price's unit or period — is the suspect. 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.
