What happens to $5,000 at 6% over 5 years?
If you invest $5,000 today at a 6% annual interest rate and leave it untouched for 5 years — with interest compounding annually — you end up with $6,691.13. That means your original principal earns $1,691.13 in compound interest, bringing your total return to 33.8% over the investment period.
The key driver is compounding: each year you earn interest not only on your original $5,000, but also on all the interest that has accumulated in prior years. In year one you earn $300.00, but by year 5 that annual interest payment grows to $378.74 — the same percentage applied to a much larger base.
At 6%, money doubles approximately every 11.9 years (Rule of 72: 72 ÷ 6 = 12.0). Over a 5-year horizon that translates to a 1.34x growth multiple.
These figures assume a constant 6% rate, annual compounding, and no withdrawals or additional deposits. Use the interactive calculator below to model monthly contributions, different compounding frequencies, or any custom scenario.
