What this specific question is asking

Before running ROI Calculator, write down what amount invested and final value 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.

Test the setup before trusting the output: rerun the example with a doubled amount invested and see whether the result behaves as the formula implies. Direction first, precision second.

Inputs to verify

Verify amount invested before calculation; if this value uses a different unit, period or definition, convert or restate it first.
Verify final value before calculation; if this value uses a different unit, period or definition, convert or restate it first.

Step-by-step check

Enter the amount you invested.
Enter the final value you received or expect.
Keep the invested and final amounts as plain numbers.

Worked example and sanity check

As a worked reference for “Margin vs ROI”, Worked example Investing 50,000 and receiving 65,000: ROI = (65,000 − 50,000) ÷ 50,000 × 100 = 30% .

Interpreting the result

So what does the number mean? In the worked example the calculation produced (65,000 − 50,000) ÷ 50,000 × 100 = 30%. A result in that range is plausible for this kind of input; if your result lands far from it, revisit amount invested 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.
