The Power of Compound Interest in a Roth IRA

Why Time Matters More Than Timing

Albert Einstein famously called compound interest the eighth wonder of the world. In the context of a Roth IRA, compounding is even more extraordinary because the IRS cannot take a single penny of your investment earnings when you make qualified withdrawals.

The Math Behind Compounding

When you invest $7,500 every year at an average annualized rate of return of 7%:

• After 10 Years: You have invested $75,000. Your balance is approximately $111,000 (growth: $36,000).
• After 20 Years: You have invested $150,000. Your balance is approximately $330,000 (growth: $180,000).
• After 30 Years: You have invested $225,000. Your balance reaches $760,000+ (growth: $535,000+).
• After 35 Years: Your balance crosses $1,100,000, with over $835,000 in pure tax-free growth!

The most staggering aspect of this projection is that more than 75% of your final portfolio comes from compound earnings, not from the money you took out of your paycheck.

Start as Early as Possible

The single biggest determinant of retirement wealth is not picking the hot stock of the week; it is the total number of compounding cycles your money enjoys. Even small monthly contributions of $200 started in your 20s will often outpace $600 monthly contributions started in your 40s.
