Return on Investment (ROI): What It Is and Why It Matters for Your Business

Return on Investment (ROI) formula with example

Return on Investment (ROI) is a key financial metric used to evaluate the efficiency and profitability of an investment. Simply put, ROI measures the gain or loss generated on an investment relative to its cost. It’s widely used by businesses, investors, and marketers to determine whether a particular investment is worth pursuing.

Why ROI Matters

Whether you’re a small business owner, a marketing professional, or a corporate decision-maker, understanding ROI helps you:

  • Assess the performance of investments
  • Compare the profitability of different ventures
  • Make data-driven financial decisions
  • Optimize resource allocation

A high ROI means the investment gains compare favorably to its cost, while a low ROI indicates less efficient use of capital.

How to Calculate ROI

The basic formula for ROI is:

ROI = (Net Profit / Cost of Investment) x 100

Example:

If you invest $1,000 in a marketing campaign and earn $1,500 in revenue from that campaign, your ROI would be:

ROI = (1,500 – 1,000) / 1,000 x 100 = 50%

This means you gained 50% profit from your original investment.
