How Compound Interest Works
Compound interest is calculated on the original principal and on interest accumulated over time. Actual account returns and terms vary.
Rate and Compounding
The assumed rate and how often interest is added can change the projected future value.
Time Makes a Difference
Longer periods can magnify growth effects, but projections are not guarantees of future returns.
