Earning interest on interest is called ___________________.
compound interest.
If a bank calculated the interest only on your original investment, you would be paid ________________, which is not compounded.
simple interest

more
Present value = __________________________
(future value after t periods)/(1+r)^t
To calculate present value, we discount the future value at the interest rate r, this is known as a _______________.
discounted cash flow.
The __________________ is the interest rate used to compute the present value of future cash flows.
discount rate
t/f: present values are always calculated using compound interest.
True
T/F: You should never compare cash flows occurring at different times without first discounting them to a common date.
