See how your principal grows with compound interest over time.
Compound interest pays interest on previously earned interest, so the balance grows faster than linear each year. More frequent compounding, like monthly rather than yearly, slightly increases the final amount. Compounding is the engine of long-term wealth, so small rate differences compound into very large differences over decades.
