Compounder

Compounder, allows you to quickly calculate compounding interest. What exactly is compound interest?
Interest calculated on the initial principal and also on the accumulated interest of previous periods of a deposit or loan.

For example, if you start with $1000 in your savings account and each month you contribute $500 at 10% interest annually. After 30 years, guess how much the account will be worth. The answer, $2.28 Million! You're only putting in $500/month(the average car payment in America) at just 10% interest(Same interest the S&P 500 has averaged over the past 90 years).
You don't have to be some bi​g Wall Street broker to become a millionaire.
