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 lkey. Performing the calculation causes the “7” to change back to “=”.

kCash 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 ValueIRR : Internal Rate of ReturnPBP : 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).
