2. Payback Period
Def i ni t i on:
The Payback
peri od i s t he amount
of t i me t hat i t t ake
t o recover your cos t s
i n a proj ect .
3. FORMULA: Payback
Period Even Or Uneven
Even:
Payback Period = I nit ial I nvest ment /
Annual Cash f lows
Uneven:
Paybeck Period=A+(B/ C)
Where; A=The Last period wit h a negat ive
cumulat ive cash f low
B=The absolut e value of cumulat ive cash
4. Example
Even Cash Flow:
Company Cis planning to undertake a project requiring initial
investmentof$105million. Theprojectisexpectedtogenerate
$25millionperyearfor7years. Calculatethepaybackperiodof
theproject.
8. Payback Period Rule
The Decision Rule: t he act ual
payback is compared wit h a
predet ermined pay back, t hat
is, t he pay back set by t he
management in t erms of t he
maximum period during which
t he invest ment must
recovered.

10. Disadvantage Of

The pay back period ent irely
ignores t he cash inf lows t hat

The pay back period also
ignores salvage value and

12. Time Value Of Money
The concept modern f inance
and management .
We say t hat money has a t ime
value because t hat money can
be invest ed wit h t he
expect at ion of earning a
posit ive rat e of ret urn
13. Calculations based on the
time value of money
Present Value - An amount of
money t oday, or t he cur rent
value of a f ut ure cash f low
Future Value - An amount of
money at some f ut ure t ime

16. Example
Consider 2 sit uat ions
Opt ion A: You receive Rs.

Opt ion B: You receive Rs.

22. (Internal Rate of
Return) IRRThe I RR should be applied only
f or very simple invest ment s.
I nt ernal rat e of r et urn (I RR) is
t he discount rat e at which t he
net present value of an
invest ment becomes zero. I n

discount rat e which equat es t he

26. NPV at 10% discount rat e =
$18,372
Since NPV is great er t han zero
we have t o increase discount
rat e, t hus
NPV at 13% discount rat e =
$4,521
But it is st ill great er t han zero
we have t o f urt her increase t he
discount rat e, t hus
NPV at 14% discount rat e = $204
27. Cont…
First , imagine a sit uat ion in
which you invest $1 million
t oday and t hen receive
$500,000 per year f or t he next
4 years. That invest ment gives
an I RR of 35%, which would be
pret t y good by t oday’s
st andards. Now let ’s change
28. I f inst ead you had t o invest only
$500,000 up f ront f or t he same
amount of ret urn, t he I RR
improves t o 93%.For t hose of you
unf amiliar wit h t he t erminology, a
proj ect wit h an I RR of 93% is bot h
r ar e and ver y desirable t o pursue.
The reduct ion in t he up-f r ont
invest ment caused t he ret urn t o
skyrocket .
29. CONCLUSION
Any t ime you ar e evaluat ing an
invest ment over t ime, use t ime-
