How to interpret the result
Total accumulated
Sum of initial capital, contributions, and all interest over the period.
You invested
How much came out of your pocket — the base upon which interest accrues.
Interest earned
What your money produced on its own. The longer the timeframe, the larger this share.
Tip: to convert an annual rate to monthly, use (1 + annual rate)^(1/12) − 1. An annual rate of 11.5% is approximately equivalent to 0.91% per month.
