Using

SOLVE

Effectively

The

program uses

the

convention

that

money received

entered

and

displayed

as a

positive number,

and

that

money paid

out is

entered

and

displayed

as a

negative number.

The

program

has the

following

characteristics:

• The

cash

flow

sequence (including

the

initial

investment)

must contain both

positive

flow

and a

negative

flow.

That

is,

there must

be at

least

one

sign change.

•

Cash

flows

with multiple sign changes

may

have more

than

one

solution. This program

may

find

one

solution,

but it has

no way of

indicating other possibilities.

• The

IRR

calculation

may

take several minutes

(5 or

more)

depending

of the

number

cash

flow

entries.

• The

program displays

Error

4 if it is

unable

find

solution

for

IRR or if the

yield

-100%

in the NPV

calculation.
