What is Compound Interest?

Frequently Asked Questions
What is the difference between simple and compound interest?
Simple interest is calculated only on the principal amount. Compound interest adds profits back to the principal, creating accelerated "exponential" growth.
Do the results reflect inflation?
These are nominal figures. To estimate purchasing power, subtract the expected inflation rate from the interest percentage you enter.
