Invest $7,000 a year in a Roth IRA, reinvest the dividends, and leave it alone for 29 years. Here’s what it could grow to.
We use the Vanguard Target Retirement 2055 Fund as our reference, including its 11% average over the last 10 years, and show three possible outcomes.
$654K
Cautious, 7% a year
$947K
Middle, 9% a year
$1.39M
11% a year, if the last decade repeats
Value at the end of 2054 from $203,000 of total contributions ($7,000 at the start of each year, 2026–2054).
How the reference fund has performed
The Vanguard Target Retirement 2055 Fund holds U.S. and international stocks plus bonds in one fund. It has averaged about 11% a year over the last decade.

Will 11% continue? It might not. The last decade included one of the strongest U.S. stock markets on record, and the fund still had losing years, including −7.89% in 2018. As 2055 approaches, the fund also shifts toward bonds, which typically lowers returns. That’s why we treat 11% as the optimistic case and also show 7% and 9%.
What $7,000 a year could become
Growth starts slowly, then accelerates. In the middle case, the account passes $100,000 in year ten and grows by about $235,000 in the final three years alone.
Account value at each year end, dividends reinvested
Assumes a steady return every year. Real returns rise and fall, so actual balances will take a bumpier path.
Milestones along the way
| End of year | You’ve put in | 7% a year | 9% a year | 11% a year |

| 2030 | $35K | $43K | $46K | $48K |
| 2035 | $70K | $103K | $116K | $130K |

| 2050 | $175K | $474K | $646K | $889K |
| 2054 | $203K | $654K | $947K | $1.39M |
Where the money comes from
Your contributions total $203,000 in every scenario. Everything above that is investment growth, and in a Roth IRA it comes out tax-free in retirement.
Value at the end of 2054: contributions vs. growth
What moves the number
+7%
Contribute the full limit
Putting in $7,500 a year (the 2026 limit) instead of $7,000 raises every ending balance by about 7%.
Reinvest
Keep dividends working
Reinvested dividends buy more shares, which earn their own returns. The projections above assume this.
Stay in
Don’t sell in a downturn
The largest gains arrive in the final years. Selling during a drop can lock in losses and miss the recovery.
≈ $402K
Think in today’s dollars
With 3% yearly inflation, the $947K middle case would buy roughly what $402K buys today.
