See what $1,000 invested once for 30 years could grow to, with the 5%, 7% and 10% return scenarios, the compound-growth formula and a year-by-year chart.
| Annual return | Future value | Total growth |
|---|---|---|
| 5% | $4,322 | $3,322 |
| 7% | $7,612 | $6,612 |
| 10% | $17,449 | $16,449 |
FV = P × (1 + r)n, where P = $1,000, r = 7% per year, n = 30 years.
A one-time $1,000 investment left to compound for 30 years at a 7% average annual return grows to about $7,612 — turning your original $1,000 into $6,612 of additional growth on top of what you put in. Because returns compound on previous returns, the balance curve steepens over time; most of the gain in a long horizon arrives in the final years. These figures assume a constant return and reinvested earnings; real markets fluctuate year to year, and taxes and fees reduce net returns.
