Explanation of Results
Future Value is the total amount at the end of the period. Total Interest Earned is your profit above the original deposit. Effective Annual Rate is the real yearly return after accounting for compounding — it is always slightly higher than the stated rate when compounding is more frequent than annually. Total Compounding Periods is the number of times interest was applied.
