UNLOCK THE SECRET OF GROWING YOUR MONEY.

The rule of 72

By MzwandilePublished 2 years ago 4 min read

Current inflation Rate: 8%

Calculation: 72 / 8 = 9 yrs

Results: In 9 years, your $10,000 will only be worth $5000 in today's dollars.

How accurate is it?

The rule of 72 works best for interest rates between 6% and 10%. If your rate is outside this range you can tweak the formula a bit. Just add or subtract 1 from 72 for every 3% the rate is away from 8%.

Tweaking the rule

Interest rate: 11% ( which is 3% higher than 8% )

Adjust the rule: 72 + 1 = 73. then in this case use 73 instead of 72

Calculation: 73 / 11 = 6.6 years to double your money

Interest rate: 5% ( Which is 3% lower from 8% )

Adjust the rule: 72 - 1 = 71. then in this situation, we use 71 instead of 72

Calculation: 71 / 5 = 14.2 years to double your money.
