Roth IRA 35-Year Compound Growth Example
Scenario Context: A 30-year-old investor starts a Roth IRA with $5,000 and contributes $500 per month ($6,000 per year) until retiring at age 65 (35 years) assuming an 8% average return.
Step 1: Total Out-of-Pocket Contributions = $5,000 + ($6,000 × 35 years) = $215,000
Step 2: Future Value of Initial Deposit = $5,000 × (1.08)^35 = $73,927
Step 3: Future Value of Annual Contributions = $6,000 × [((1.08)^35 - 1) / 0.08] = $1,033,901
Step 4: Total Roth IRA Nest Egg at Age 65 = $73,927 + $1,033,901 = $1,107,828
Step 5: Tax-Free Investment Growth = $1,107,828 - $215,000 = $892,828
Investing $500/month builds a $1,107,828 retirement nest egg with $892,828 in completely tax-free capital gains.
