You are on track. Your projected corpus of $1,801,055 exceeds the $1.25M typically needed for a comfortable retirement (assuming $50K/year expenses). Your $6,004/month withdrawal is well above the minimum needed.
Starting at 25 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 25, saving $1,000/month at 7% annual returns builds a portfolio of $1,801,055 by age 60. Using the 4% safe withdrawal rate, this provides $6,004/month ($72,042/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 $1,801,055 portfolio, that means $72,042/year or $6,004/month. This rule was developed from the Trinity Study analyzing historical market returns.
Out of your $1,801,055 total, $420,000 comes from your own contributions and $1,381,055 (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.
