Interest vs. the 4% Rule
Living only on interest keeps your principal intact, but cash rates move with the Federal Reserve: when rates fall, your income falls too. The 4% rule takes a different approach — invest in a diversified stock and bond portfolio and withdraw 4% in the first year, then adjust for inflation. On $3 million that's about $10,000 per month, and historically it has lasted at least 30 years in most scenarios.
Is $3 million Enough to Retire?
The average American household spends about $6,440 per month. A $3 million portfolio covers the average American household's spending — a realistic early-retirement number for most people. Add Social Security, a pension or part-time income and the picture improves quickly.
How Long Does It Take to Save $3 million?
Starting from zero and earning 7% a year after inflation (the stock market's long-term real average):
| Monthly investment | Time to reach $3 million | Total contributed |
|---|---|---|
| $500/month | 52 years and 7 months | $315,500 |
| $1,000/month | 42 years and 9 months | $513,000 |
| $2,000/month | 33 years and 3 months | $798,000 |
| $5,000/month | 21 years and 11 months | $1,315,000 |
Everything above what you contributed comes from compound growth — which is why starting early matters more than starting big.
