Return on Investment (ROI) Formula

Formula
\[ ROI = \left( \frac{\text{Earnings} – \text{Investment}}{\text{Investment}} \right) \times 100 \]

Where:

  • $$ROI$$ = Return on Investment (as a percentage)
  • $$Earnings$$ = Total returns or income from the investment
  • $$Investment$$ = Initial capital or amount invested


ROI – Calculation Example

Suppose you invested $5,000 in a project and earned $6,200 from it.

Calculation:

  1. $$ROI = \left( \frac{6,200 – 5,000}{5,000} \right) \times 100 = \left( \frac{1,200}{5,000} \right) \times 100 = 24\%$$

So, your return on investment is 24%.


The ROI Calculator is a simple yet powerful tool for evaluating investment efficiency. It tells you how much profit or loss you made in percentage terms, helping you compare investment opportunities or review past financial decisions.
