How This Was Calculated

The compound interest formula used:

A = P(1 + r/n)nt

Where P = $1,000,000.00, r = 4% (0.04), n = 12 (monthly compounding), t = 30 years. This gives A = $1,000,000.00 × (1 + 0.04/12)^(360) = $3,313,498.01.

Frequently Asked Questions

At 4% annually, $1 million generates approximately $40,000 per year in interest income. With monthly compounding, you earn slightly more. If you reinvest the interest, your balance grows significantly over time.

The 4% rule suggests you can withdraw 4% of your portfolio annually ($40,000 from $1 million) with a high probability of your money lasting 30+ years. However, this depends on your expenses, inflation, healthcare costs, and investment returns. Many financial planners now suggest a more conservative 3-3.5% withdrawal rate.

A diversified investment portfolio typically outperforms savings accounts over long periods. For retirement, a mix of stocks and bonds appropriate for your age and risk tolerance is generally recommended. Consult a financial advisor for personalized advice.
