Note

  This calculator performs interest (I) calculations using

Newton's Method, which produces approximate values

whose precision can be affected by various calculation

conditions. Because of this, interest calculation results

produced by this calculator should be used keeping the

above limitation in mind, or the results should be verified.

  When you use f and c to select an item that can be

calculated, the  =  changes to  7 . You can perform a

calculation by inputting the required values for the other

items, and then pressing the l key. Performing the

calculation causes the  7  to change back to  = .

k Cash Flow Mode

  The Cash Flow (CASH) mode calculates the total of

income and expenses over a fixed period, and then uses

the discounted cash flow (DCF) method to perform

investment appraisal. The following four items are

appraised.

NPV

: Net Present Value

IRR

: Internal Rate of Return

PBP

: Payback Period*

NFV

: Net Future Value

* The payback period (PBP) can also be called the

 discounted payback period  (DPP). When the annual

interest rate (I) is zero, the PBP is called the  simple

payback period  (SPP).
