  • An error (Ma ERROR) occurs if parameters are not configured correctly.
  Use the following function menus to maneuver between calculation result screens.
  • { REPT } … {parameter input screen}
  • { GRPH } … {draws graph}
  After drawing a graph, you can press !1(TRCE) to turn on trace and read calculation 
results along the graph.
  Press J to return to the parameter input screen.
5. Amortization
 This calculator can be used to calculate the principal and interest portion of a monthly 
installment, the remaining principal, and amount of principal and interest repaid up to any 
point.
u Formula
 a  : interest portion of installment PM1 ( INT )
 b  : principal portion of installment PM1 ( PRN )
 c  : balance of principal after installment PM2 ( BAL )
 d  : total principal from installment PM1 to payment of installment PM2 ( Σ PRN )
 e  : total interest from installment PM1 to payment of installment PM2 ( Σ INT )
  * 
a  + b  = one repayment ( PMT )
