How to use

Perform time value of money calculations by entering the number of periods (N), interest rate per period (I/Y), present value (PV), payment (PMT) and future value (FV) as required, then press the appropriate solve key to compute the unknown variable. For cash flow analysis, enter each cash flow amount in sequence and use the dedicated cash flow and IRR/NPV keys to compute internal rate of return or net present value. Use the amortization functions to generate interest and principal breakdowns for loan schedules, and the bond functions to evaluate price and yield based on coupon rates and settlement/maturity inputs. Follow on-screen prompts and refer to the function labels on the keypad for correct key order.

Recommendations

To ensure accurate results, set the calculator's decimals, compounding frequency and payment conventions to match the assumptions of your calculation or exam rules before starting. Replace batteries as needed and keep the unit in its protective cover when transporting to prevent accidental key presses and to extend service life.
