What will $250k grow to in 40 years?
$250,000 invested for 40 years at a 7% average annual return grows to about $3,743,614. That's roughly 15× your starting amount, all from compounding.
The growth comes entirely from compounding. Each year's return earns returns of its own. At a 7% average annual return (Rightmont's long-horizon diversified assumption), a one-time $250,000 becomes about $3,743,614 after 40 years, with no further contributions.
This is nominal growth, before inflation. Over 40 years, inflation erodes purchasing power, so the real spending value is lower. That's the reason to plan in present-day dollars, and Rightmont's projections show both.
Annual return vs outcome
The same question at every rate, so you can use the one you believe.
| Annual return | Value after 40 years |
|---|---|
| 4% | $1,200,255 |
| 5% | $1,759,997 |
| 6% | $2,571,429 |
| 7%our default | $3,743,614 |
| 8% | $5,431,130 |
| 10% | $11,314,814 |
Returns are an assumption, not a forecast, and no one earns the same percentage every year. These are nominal figures before inflation and before tax on any gains realised along the way.
