What will $1M grow to in 25 years?

$1,000,000 invested for 25 years at a 7% average annual return grows to about $5,427,433. That's roughly 5.4× 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 $1,000,000 becomes about $5,427,433 after 25 years, with no further contributions.

This is nominal growth, before inflation. Over 25 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.

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.

Frequently asked

How much does $1M become in 25 years?

About $5,427,433 at a 7% average annual return, from compounding alone.

Does this account for inflation?

This is the nominal figure. At 3% inflation, the real, present-day value is meaningfully lower. Rightmont models both.

What if returns are higher or lower than 7%?

Over 25 years the return assumption dominates the result. The table on this page shows $1,000,000 at 4% through 10% so you can pick the one you believe.

How much will $1M be worth in 25 years?

About $5,427,433 at a 7% average annual return. That is the nominal figure, before inflation.

What is $1M invested for 25 years?

Roughly $5,427,433, assuming a 7% average annual return and no further contributions.
