The Core Projection: $1,000/Month at Various Returns
$1,000/month DCA portfolio value at 10, 20, and 30 years across return scenarios
| Return Rate | After 10 Years | After 20 Years | After 30 Years | Total Invested |
|---|---|---|---|---|
| 6% | $163,900 | $462,000 | $1,004,500 | $120K/$240K/$360K |
| 8% | $182,900 | $589,000 | $1,499,000 | same |
| 10% | $204,800 | $759,000 | $2,278,000 | same |
| 12% | $230,000 | $988,000 | $3,529,000 | same |
At historical average 10% return: $2.28 million from $360,000 invested. At more conservative 8%: $1.5 million. Both represent 4x+ multiplication of invested capital through compound growth alone.
Real (Inflation-Adjusted) Purchasing Power
At 3% inflation, $1.5 million in nominal 30-year future dollars is worth about $618,000 in today’s purchasing power. At $2.28 million nominal: $940,000 in today’s dollars. Still significant, but the inflation adjustment reframes the milestone — $1 million in 2055 is not the same as $1 million today.
