1. Future Value
refers to the amount of money an investment will grow to over some period of time at some given interest rate

cash value of an investment at some time in the future
2. Single period investment
• Investment = (1+r)
• where r= interest rate, rate of return or discount rate per period
3. compound interest
earning interest on interest

Future value interest factor, or future value factor (FVIF) = (1 * r)^t

• ex: \$100 worth after 5 yrs with 10% interest
• (1+.10)^5= 1.1^5= 1.6105
• 100*1.6105= \$161.05

increases each year
4. simple interest
interest is not reinvested so interest earned each period only on the original principal

- constant each year
5. present value
the current value of FCF (future cash flows) discounted at the appropriate discount rate

• Single period
• PV= \$1* [1/(1+r)]
• = \$1/(1+r)

• Mupltiple periods
• PV= \$1*[1/(1+r)^t]
• =\$1/(1+r)^t
6. Discount rate
the rate used to calculate the present value of FCFs

1/(1+r)^t
7. discounted cash flow (DCF)
valuations calculating the present value of a future cash flow to determine its value today
8. Discount rate
• Discount factor
• Present value interest factor (PVIF)
• Present value factor
9. for a given length of time, the higher the discount rate is, the lower is the present value
PV and discount rates are inversely related

increasing the dicount rate, decreases the present value
10. Present value factor is the reciprocal of the future value factor
• FCF = (1+r)^t
• PVF = 1/(1+r)^t

easy way to calculate a PVF is to first calculate the FVF and then press the 1/x key to flip it over

PV*(1+r)^t= FV

• PV= FV/(1+r)^t
• FV*[1/(1+r)^t]
11. Rule of 72
For reasonable rates of return, the time it takes to double your money is given approx by 72/r%

(fairly accurate for discount rates in the 5-20% range)

ex: potential investment to double your money every ten years, what is the rate of return? 72/10=7.2%

want to purpose an asset costing 50K, currently have 25K, 12%, how long will it take? 72/12= 6yrs at 12%
