CASIO Europe GmbH Bornbarch 10, 22848 Norderstedt, Germany About this Manual · This User's Guide covers use and operation of the CASIO FC-200V and FC-100V. [. . . ] Example 5: To calculate total principal paid (PRN) from payment 15 (PM1) to payment 28 (PM2) · In step 2 of the basic procedure (Example 1), select "PRN:Solve". A AMRT Mode Financial Calculation Variables (VARS) · Variables PM1, PM2, n, I, PV, PMT, FV, P/Y, and C/Y are used in the AMRT Mode. · The values of AMRT Mode variables are retained even if you change to another mode. Note, however, that AMRT Mode variables are also used by other modes, so performing an input or calculation operation may change the values assigned to them. · Though AMRT Mode variables are financial calculation variables, they are also used by arithmetic and function operations in the COMP Mode. E-58 A Calculation Formulas a: Interest portion of payment PM1 (INT) INTPM1 = I BALPM1­1 × i I × (PMT sign) b: Principal portion of payment PM1 (PRN) PRNPM1 = PMT + BALPM1­1 × i c: Principal balance upon completion of payment PM2 (BAL) BALPM2 = BALPM2­1 + PRNPM2 d: Total principal paid from payment PM1 to payment PM2 (PRN) PRN = PRNPM1 + PRNPM1+1 + . . . + PRNPM2 PM2 PM1 e: Total interest paid from payment PM1 to payment PM2 (INT) · a + b = one repayment (PMT) PM2 PM1 INT = INTPM1 + INTPM1+1 + . . . + INTPM2 (Setup Screen) BAL0 = PV . . . . . . . . . . . . . . . . . . . . . . . Payment: Begin (Setup Screen) Converting between the Nominal Interest Rate and Effective Interest Rate The nominal interest rate (I % value input by user) is converted to an effective interest rate (I %´) for installment loans where the number of annual payments is different from the number of annual compoundings calculation periods. I%' = (1+ The following calculation is performed after conversion from the nominal interest rate to the effective interest rate, and the result is used for all subsequent calculations. { [P / Y ] I% ) ­1 ×100 100 × [C / Y ] [C / Y ] } i = I%'÷100 k Conversion Mode · The Conversion (CNVR) Mode lets you convert between the nominal interest rate (APR) and effective interest rate (EFF). E-59 A Entering the CNVR Mode · Press n to enter the CNVR Mode. Value Input Screen A Setting Values No. Display 1n 2I Name Number of Annual Compoundings Interest Rate (Annual) Values Used in Examples 6 3% A Basic CNVR Mode Procedure Example 1: To convert a nominal interest rate (APR) to an effective interest rate (EFF) 1. Input the number of annual compoundings (n) and interest rate (I) values from the Setting Values table above. · For this example, use fc to select 1 "n", input 6, and then press E. · Use fc to select 2 "I", input 3, and then press E. · For this example, use fc to select "EFF: Solve". Press l to perform the calculation. · Pressing the E key returns to the value input screen. E-60 A Other CNVR Mode Calculations Example 2: To convert an effective interest rate (EFF) to a nominal interest rate (APR) · In step 2 of the basic procedure (Example 1), select "APR: Solve". A CNVR Mode Financial Calculation Variables (VARS) · Variables n and I are used in the CNVR Mode. · A value is assigned to I whenever you perform an EFF or APR calculation in the CNVR Mode. · The values of CNVR Mode variables are retained even if you change to another mode. Note, however, that CNVR Mode variables are also used by other modes, so performing an input or calculation operation may change the values assigned to them. · Though CNVR Mode variables are financial calculation variables, they are also used by arithmetic and function operations in the COMP Mode. A Calculation Formulas n APR/100 EFF = 1+ ­1 × 100 n 1 APR = 1+ EFF 100 n ­1 × n ×100 APR : nominal interest rate (%) EFF : effective interest rate (%) n : number of annual compoundings k Cost/Sell/Margin Mode · The Cost/Sell/Margin (COST) Mode lets you calculate cost, selling price, or margin after inputting the other two values. You can input the cost and selling price, for example, and calculate the margin. E-61 A Entering the COST Mode · Press o to enter the COST Mode. Value Input Screen A Setting Values No. Display 1 CST 2 SEL 3 MRG Cost Selling Price Margin Name Values Used in Examples $40 $100 60% A Basic COST Mode Procedure Example 1: To calculate the margin (MRG) 1. [. . . ] The TWO WAY POWER system, however, lets you continue to use the calculator as long as there is enough light to read the display. A Replacing the Battery Dim display figures when available lighting is dim or failure of anything to appear on the display immediately when you turn on the calculator indicates that button battery power is low. Note that you will not be able to use the calculator if its button battery is dead. When any of these symptoms occur, replace the button battery. Even if the calculator is operating normally, replace the battery at least once every three years. Important! [. . . ]
