How Long Does It Take to Double Your Money? (Rule of 72)
The Answer
9 years at 8%
The Full Picture
Divide 72 by your annual return percentage to find doubling time. At 8%, your money doubles every 9 years. $10,000 becomes $20,000 at year 9, $40,000 at year 18, and $80,000 at year 27. At 6%, it takes 12 years to double. At 12%, just 6 years.
