I'll give you a 1 million dollar investment with 13% compounded interest over 2 weeks. At 2 weeks the money should be returned to me. Should it not, the compounded interest rate of 13% will increase by 1% every day that the money is not returned.
At 2 weeks, that's 1,130,000.00 you will owe me. Then 13% per day plus 1% additional is added per day after it is not payed back. All interest is compounded*
