This conversion is required for installment savings accounts, loan repayments, etc. t Th I%'={(1I%100[C/Y])[C/Y][C/Y]1}100 P/Y:installment periods per year C/Y:compounding periods per year When calculating n, PV, PMT, FV \he 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.

Inputting Values peA period (n) is expressed as a positive value. Either the present value (PV) or future value (FV) is positive, while the other (PV or FV) is negative. Precision \hisThis calculator performs interest 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. iAfter configuring the parameters, use one of the function menus noted below to perform the corresponding calculation. @FINANCE[EXE] 8Pack*?( @GUIDEKEYLOG(NOTE%2%)!$00yz
