Introduction: How Fast Can You Build Wealth? Learn about the Rule of 72 and Risk in Investing!
Every investor dreams of doubling their money, but few know the simple math behind it. The Rule of 72 and Risk in Investing is a classic formula that helps predict how long it will take to double an investment based on the rate of return.
But hereβs the twist: the higher the risk, the faster your money grows. The question isβhow much risk should you take? Letβs break it down and find out how you can make the Rule of 72 and Risk in Investing work for you.
What is the Rule of 72 and Risk in Investing?
The Rule of 72 and Risk in Investing is an easy way to estimate how many years it will take for an investment to double given a fixed annual return.
Formula:
π 72 Γ· Annual Return (%) = Years to Double
Examples:
- If you earn 8% per year, your money doubles in 9 years (72 Γ· 8 = 9)
- If you earn 12% per year, it only takes 6 years
- If you earn 24% per year, your money doubles in just 3 years
π Higher returns = faster doubling. This is why riskier investments often lead to bigger gains (but also bigger losses).

Bonds (4%) | 4% | 18 years |
