What will $1M grow to in 15 years?
$1,000,000 invested for 15 years at a 7% average annual return grows to about $2,759,032. That's roughly 2.8× your starting amount, all from compounding. In today's dollars, at 3% inflation, that is about $1,770,918.
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 $1,000,000 becomes about $2,759,032 after 15 years, with no further contributions.
This is nominal growth, before inflation. Over 15 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 annual return, so you can use the one you believe.
| Annual return | Value after 15 years |
|---|---|
| 4% | $1,800,944 |
| 5% | $2,078,928 |
| 6% | $2,396,558 |
| 7%our default | $2,759,032 |
| 8% | $3,172,169 |
| 10% | $4,177,248 |
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.
What it is worth after inflation
The same growth in today's dollars, at every annual return.
| Annual return | In today's dollars after 15 years |
|---|---|
| 4% | $1,155,957 |
| 5% | $1,334,385 |
| 6% | $1,538,259 |
| 7%our default | $1,770,918 |
| 8% | $2,036,095 |
| 10% | $2,681,217 |
The nominal values above, deflated by 3% inflation a year over the same horizon, so they show what the money will buy at today's prices. Inflation is an assumption too, and it compounds.
