Chapter 1 - Compounding Flashcards
What is the formula for continuous compounding?
FV = PV(1+r)^n
Rate of Return (r)
n square root (FV/PV) - 1 = r
All spin offs of FV = PV(1+r)^n
AER/APR/EAR
To calculate the correct rate of return taking into consideration interest payments made at intervals more frequent than annually -
And considering the subsequent returns for the remainder period are based on the original capital plus the interest payments paid throughout the term
AER/APR/EAR
= (1+r/n)^n
AER/APR/EAR
To establish the annual rate from the monthly rate
Calculates an annual effective rate from the monthly rate of interest
Annualised Returns ….
APR
= (1+monthly rate)^12 - 1
Annualised returns - similar but with ^1/n rather than 12
An=(1+return)^1/n - 1
REGULAR SAVINGS - FV
ACCUMULATION
Calculates the FB of a series of payments plus interest
ANNUITIES - calculates lump sum required, PV generate a stream of income/payments over a set term at a set rate
F = P x (1+r)^n - 1/r
A = P x {1-(1+r)^-n} / r
Real return
Real return = nominal return minus inflation
Holding Period Return
Calculates the return on an investment (incl DVDs & Wdls) as a % of the original amount
HPR = D + V1. - V0 / V0
Money weighted return - MWR
Calculates the return on an investment, adjusted for any cash flows into the portfolio over the term
Time Weighted Return - TWR
Allows for comparison of performance btw diff FMs as it minimises distortion caused by the timing of cash flows which may be outside the FM control
MWR =
D+V1-V0-C / V0+(C x n/12)
TWR =
1+r = (1+R1) x ( 1+ R2) … (1+R3) etc
