Discounted cash flows (DCF)
 We
estimate how much we will spend or make for
a number of periods in the future, a series of cash flow we estimate
for an action
plan.
What is the rate of
growth or decline - the internal rate of return (IRR)? Using Excel's IRR
function for the example, 10.6% is the internal rate of return that explains
this flow
of funds.
Net Present Value (NPV)
A better question to ask is: will the cash flows
return more than making the same investment of $44.70 in
another opportunity with a known rate of return, for example, for an
AAA corporate bond at 10.0%? When you use Excel to calculate NPV, you
provide
that discount rate.
The Excel setup with a 10% discount rate and five years of cash
flows is:
0.5 = NPV(10%, -44.7, 16.0, 14.7, 13.9, 11.9)
Making judgments using NPV
The
NPV of 0.5 is positive, so it is better to invest in the project.
That makes sense; the IRR in the example for discounted cash flows
above was 10.6%, slightly better than the threshold discount rate
10% we used in the NPV calculation. If NPV were zero, it would be the
same
as
the
alternative investment. If the NPV is less than zero, it would be worse.
