Start Early
The earlier you start, the more time your money has to compound. Even small amounts grow significantly over decades.
Compounding Frequency
More frequent compounding (monthly vs annually) results in slightly higher returns. Daily compounding gives the best results.
Consistent Contributions
Adding to your investment regularly dramatically increases final value through "compound interest on contributions."
