Learn shorcut formula's and characteristics
What are the key characteristics of an annuity with growth? (six characteristics)
- ) cash flow occurs at the end of the first period
- ) cash flows must grow at a constanst rate each period
- ) timing of cash at constant intervals
- ) discount rate is the effective rate and is constant over time
- ) n time periods between the cash flows, where n is finite
- ) the PV valuation is one period before the first cash flow
What is the Geometric series SUM formula
Sn= a (1-x^n) / (1-x)
What is the Geometric series sum formula if n tends towards infinity
|x| <1 S= a/ 1-x
Write the PV Annuity with Growth Formula
PV= C [ 1 - (1+g / 1+r)^n / r-g ]
Write the Converting a Stated annual interest rate to an EAR formula
1+EAR = ( 1+stated annual interest rate / k)^k
where k is the number of compounding periods in a year
Write the Effective rate –> Stated annual interest rate formula
r(k) where r is the effective rate for the time period, k is the number of time periods in a year
Write the Stated annual interest rate to effective rate for n periods formula
[1 + (stated annual interest rate/k)]^n - 1 = Effective rate for n periods
What is the Future value formula
FV = C (1+r)^T (T is the number of time periods and r is the effective rate for the time period)
What is the Present Value formula
PV = C / (1+r)^T (T is the number of time periods)
What is the Discount Factor formula
Dt = 1 / (1+r)^T (T is the number of time periods and r is the effective rate for the time period and over time)
What is the NPV Formula Procedure
Take each cash flow and compute its present value.
Sum present values across all cash flows.
what is the formula for real interest rate.
(1+r) = (1+i) / (1+pi)
r= real interest rate I = nominal interest rate pi = inflation rate
Give the Approximation for real interest rate when rates are low
r approximately –> i - pi
I approximately —> r + pi
nominal interest rate = inflation rate + real interest rate
Real interest rate = nominal rate - inflation rate
What is the Continuous compounding formula
1+ EAR = e^p
P IS THE ANNUAL CONTINOUSLY COMPIUNDED RATE (have to use logs to find p)
Define the six characteristics of an Annuity
- ) cash flow occurs at the end of the first period
- ) cash flow must be constant each period
- ) timing of cash at constant intervals
- ) discount rate is the effective rate and is constant over time
- ) n time periods between the cash flows, where n is finite
- ) the PV valuation is one period before the first cash flow
