The Rule of 69 tells you how long it takes to double your money with different returns.
The formula is simple: 69 divided by your investment’s annual return rate. So it would be…
Annual Return (%) ➡️ Years to Double
1% ➡️ 69.0 years (69/1)
2% ➡️ 34.5 years (69/2)
3% ➡️ 23.0 years (69/3)
4% ➡️ 17.3 years (69/4)
5% ➡️ 13.8 years (69/5)
6% ➡️ 11.5 years (69/6)
7% ➡️ 9.9 years (69/7)
8% ➡️ 8.6 years (69/8)
9% ➡️ 7.7 years (69/9)
10% ➡️ 6.9 years (69/10)
