Rule of 72
To estimate how many years it takes for your money to double at a given rate, divide 72 by the annual return rate. At 10% interest, money doubles in approx 7.2 years.
Frequency Matters
More frequent compounding (e.g. Daily or Monthly vs Annually) yields slightly higher effective annual interest because interest is added back to principal more frequently.
Time is Your Best Asset
Starting early matters more than investing large amounts. Interest earned in early years compound exponentially over 20-30 year horizons.
