The Investment Profit Guide: How Smart Investors Compound Returns
A practical guide to investment profit: how returns compound, the rule of 72, and how to estimate your portfolio's growth.
The difference between average investors and great ones isn't picking the perfect stock — it's understanding how profits compound over time.
Profit vs. Return: They're Not the Same
Profit is a dollar amount. Return is a percentage. A $1,000 profit means very different things on a $5,000 investment vs. a $500,000 one.
The Rule of 72
Want to know how long it takes to double your money? Divide 72 by your annual return rate.
- 8% return → doubles in 9 years
- 12% return → doubles in 6 years
- 24% return → doubles in 3 years
Compounding: The Eighth Wonder
$10,000 invested at 10% per year becomes:
- $25,937 in 10 years
- $67,275 in 20 years
- $174,494 in 30 years
The first decade is slow. The third is explosive. That's compounding.
Estimating Your Real Profit
Use this quick framework:
- Start with gross return
- Subtract fees (often 1–2%)
- Subtract taxes (varies by account type)
- Adjust for inflation (~3% historical average)
What you're left with is your real profit.
Apply the Same Logic to Business Investments
Buying a software tool, hiring an SDR, or running a campaign is an investment. Calculate the return the same way. Try the free ROI Calculator to plug in your own numbers in under 30 seconds.
