Growth Over Time
The Power of Compound Interest
Rule of 72
Divide 72 by your interest rate to estimate years to double. At 8% interest, your money doubles in approximately 9 years.
Compound Frequency Matters
More frequent compounding means more growth. Daily compounding yields slightly more than monthly.
Start Early
Time is your greatest ally. Starting 10 years earlier can mean 2-3x more wealth at retirement.
