In this last example we could have entered values other than 1 to PM1 and still get 
the  same  result,  as  long  as  the  values  entered  are  integer 

  1.  However,  in  most 

circumstances we should always let PM1 < PM2 whenever possible (see page E-57 
of User Guide.)  
 
 

Example 2 

>>

 Referring to Example 1, find the interest portion and the principal 

portion of the 9

th

 payment.  

 

Operation 

If  you  are  doing  this  immediately  after  Example  1,  then  all  relevant  values  are  still 
intact and you can continue; otherwise you should enter those values again. 

 Enter AMRT mode, scroll down to enter 9 for [PM1], make sure [PM2] is not = 0.  

 
 
 
 

 Scroll down further to select [INT:Solve] and solve it.  

 
 
 
Therefore the interest portion of this 9

th

 payment is about $19.90. 

 

 Return to AMRT, and then scroll to select [PRN:Solve] and solve it.  

 
 
 
The calculator indicates that the principal portion of 9

th

 payment is about $203.97. 

 

 

 
Example 3 

>>

 Lucas borrows $35,000 at 

%

12

=

j

 to buy a car. The loan should 

be  repaid  with  monthly  installment  over  three  years.  Find  the  total  interest  paid  in 
the 12 payments of the second year.  
 

Operation 

Again we begin at CMPD mode to find the monthly payment of the loan.   

  Enter  CMPD  mode  and  make  sure  calculator  displays  [Set:End].  Then  scroll 

down and enter 36 for [n], 3 for [

I%

], (-)35000 for [PV], 0 for [FV], 12 for [P/Y] and 

[C/Y].  
 
 
 
 
 
 
 
 

   

   

 

Output: INT = 19.89316037 

Output: PRN = 203.9697351
