ECO 301 Lecture Notes - Lecture 4: Cash Flow
Document Summary
The same amount of money at different points in time as well as different amounts of money at the same point in time are easy to compare. Pv = present value, cf = cash flow (future) i = interest rate: cf = pv x (1 + i)^n pv = cf/(1 + i)^n. This formula and concept tells an investor how much they need to invest today in order to achieve a desired future cash flow at a given interest rate. To compare payments at different points in time you must use their present values. Yield to maturity interest rate that equates the present value of cash flow payments received from debt instruments with its value today. Implied interest rate that could be calculated even for credit market instruments that don"t have a well-defined interest rate in its usual meaning. Find the ytm of the following examples: simple loan: pv = 100, cf = 110, n = 1.
