How contributions and compounding interact

Compound growth

Compounding means returns can earn additional returns over time. Regular contributions can be as important as the assumed rate, especially over long periods.

Investment returns are not guaranteed

This is a mathematical projection. Real investments fluctuate and may lose value; fees, taxes and inflation can also change outcomes.
