Return on Investment (ROI)

What is Return on Investment?

ROI measures the gain or loss generated on an investment relative to the amount invested. It is the universal language of investment efficiency, applicable to everything from marketing campaigns to equipment purchases.

Why ROI Matters for Founders

Every dollar you spend is an investment decision. ROI helps you compare apples to oranges: should you spend $50K on a marketing campaign or $50K on a new sales hire? Calculate expected ROI for each and the decision becomes clearer.

For ecommerce founders, ROI analysis is critical for inventory decisions. That $100K in new product inventory needs to generate sufficient returns to justify the capital tied up.

Time Matters

A 50% ROI over 5 years is very different from 50% ROI in 6 months. Always consider the time frame when comparing ROI across investments.

Your SaaS company invests in a marketing campaign:

• Campaign Cost: $25,000
• Revenue Generated: $75,000
• Profit from Campaign: $50,000

ROI = (($50,000 - $25,000) ÷ $25,000) × 100 = 100%

You doubled your money on this campaign. That is a strong signal to invest more in similar initiatives.
