To make $20,000 a month ($240,000 a year) in passive income, you need roughly $6,000,000 invested using the 4% rule — or $5,454,545 if you want to live only on CD interest at today's rates. Here is the full breakdown with October 2026 rates.
How Much You Need to Make $20,000 a Month
| Strategy | Amount needed | Notes |
|---|---|---|
| High-yield savings (4.20%) | $5,714,286 | Rate can drop when the Fed cuts |
| 1-year CD (4.40%) | $5,454,545 | Rate locked for one year |
| Dividend ETF (~3.7%) | $6,486,486 | Dividends tend to grow over time |
| 4% rule | $6,000,000 | Inflation-adjusted for 30+ years |
| 3.5% rule (early retirement) | $6,857,143 | Safer for 40+ year retirements |
Reference rates (October 2026): high-yield savings 4.20% APY, 1-year CD 4.40%, 3-month T-bills 4.20%, dividend ETF yield ~3.7%, stock market long-term average 10% a year (7% after inflation). Figures are before taxes: interest is taxed as ordinary income, qualified dividends at lower rates.

The Formula
Amount needed = Monthly income × 12 ÷ yield
$20,000 × 12 ÷ 4% = $6,000,000
The lower the yield you assume, the bigger the target — but the safer your income. Cash yields look attractive today, but they follow the Federal Reserve. The 4% rule assumes a stock-heavy portfolio that grows with inflation.
How Long to Get There
Time to reach $6,000,000 investing every month at 7% a year after inflation:
| Monthly investment | Starting from $0 | Starting with $50,000 |
|---|---|---|
| $500/month | 62 years and 7 months | 56 years |
| $1,000/month | 52 years and 7 months | 48 years and 11 months |
| $2,000/month | 42 years and 9 months | 40 years and 9 months |
| $3,000/month | 37 years and 2 months | 35 years and 10 months |
| $5,000/month | 30 years and 4 months | 29 years and 7 months |
Ways to Get There Faster
- Max out tax-advantaged accounts — 401(k) match first, then a Roth IRA (see 401(k) vs Roth IRA).
- Raise contributions with every raise — increasing them 5–10% a year cuts years off the timeline.
- Reinvest dividends during the accumulation phase.
- Lower your target — every $100 less in monthly spending reduces the goal by $30,000.
