Q

Accounting Rate of Return

A

Increase in Acctg Net Income
________________________
Average Investment

Average Investment = compute for the current year net of depreciation then get the average of the ending balances for both years

Accounting net income - deduct depreciation and add tax benefit

20
Q

Net Present Value

A

PV Cash Inflows - PV of Investment (same amount)

To get the total PV of cash inflows: at hurdle rate

Make a table
Get the PV for each year (use hurdle rate)
Add up all years

Positive NPV - accept
Negative NPV - reject

21
Q

Profitability Index

A

NPV
_______
Investment

22
Q

IRR or Time Adjusted Rate of Return

A

PV of Future Cash Outflows (Investment)
________________________________
Annual Cash Inflow

= PV factor

Then look for this PV factor in the table to get the % rate of return

Then compare this to the predetermined rate of return/minimum acceptable rate of return

IRR should be > or = the desired rate of return
to be acceptable

23
Q

Stated interest rate Simple

A

P x R x T

2,000 x 6% x 2 yrs = 240

24
Q

Compound Interest Rate

A

P x (R) power of time

25
Q

Effective Interest Rate

A

2,000 X 6% X 2 = 240
2000 - 240 = 1760

ERR = 240
_____
1,760

26
Q

APR Annual Percentage Rate

A

the effective interest rate for fraction of a year

27
Q

APR formula

A

Computed as simple interest

2,000 x 6% x 90/360 (OR .25 or 4 times)

= 30

APR = 30
——– x 4
1,970

APR = 6.08%

28
Q

Ranking of interest rates

A

Stated rate 6%
Compound 6.18%
Effective Int 6.82% highest

APR 6.08% lowest
Effective APR 6.13%

29
Q

Real interest rate

A

Nominal rate + Inflation rate

30
Q

Nominal interest rate

A

Real interest rate - Inflation rate

31
Q

Inflation rate

A

Nominal - Real rate

32
Q

Annual Financing Cost on Receivables

A

% of discount 360 0r 365
_____________ X ______________
1 - % discount total period - discount period

33
Q

Cost of the loan
OR
Effective Rate of the loan

A

Interest Paid
___________________________________
Net funds (Principal - compensating balance)

34
Q

Current Bond Yield

A

Annual Interest Paid
________________
Bond Market Price

35
Q

Yield to Maturity - interest rate computation

A

(1 + r/m) m power - 1

36
Q

Yield to Maturity with Floatation Cost

A

YM = Annual Interest + Face - Bond Price
_______________
# of years
_____________________________
.60 (Bond Price) + .40 (Face Value

Bond Price = Face Value - Floatation Cost
Annual interest - sb before tax

37
Q

Bond Price formula

A

Face Value - Floatation Cost

38
