You are on track. Your projected corpus of $3,602,109 exceeds the $1.25M typically needed for a comfortable retirement (assuming $50K/year expenses). Your $12,007/month withdrawal is well above the minimum needed.
Starting at 30 gives you 35 years of compounding. This is a massive advantage. 77% of your retirement fund comes from investment growth, not your own contributions. Time is your greatest asset.
Yes. Starting at age 30, saving $2,000/month at 7% annual returns builds a portfolio of $3,602,109 by age 65. Using the 4% safe withdrawal rate, this provides $12,007/month ($144,084/year) in retirement income.
The 4% rule states that you can safely withdraw 4% of your retirement portfolio each year without running out of money over a 30-year retirement. With a $3,602,109 portfolio, that means $144,084/year or $12,007/month. This rule was developed from the Trinity Study analyzing historical market returns.
Out of your $3,602,109 total, $840,000 comes from your own contributions and $2,762,109 (77%) comes from investment growth. This shows the power of compound interest over 35 years. The earlier you start, the more growth does the heavy lifting.
