What does a $10,000 lump sum become in 10 years?

Even with zero additional contributions, a single lump sum compounds meaningfully over a decade. Here's $10,000 invested and left alone for 10 years.

Investing $10,000 once and leaving it for 10 years could grow to about $27,070.

Balance after 10 years
$27,070
Total you contribute
$10,000
Growth (compounding)
$17,070
Assumed annual return
10%

Of the ending balance, roughly $17,070 is growth you never deposited — that's compounding doing the work.

Frequently asked questions

Should I invest a lump sum all at once or spread it out?

Historically, investing a lump sum immediately beats spreading it out (dollar-cost averaging) most of the time, because markets rise more often than they fall. Spreading it out mainly reduces regret risk if the market drops right after you invest.
