Now scroll up to select [PMT] and solve it.  
 
 
 
The monthly repayment amount is $629.81. Next, find the outstanding principal after 
2 years. 
 
 Enter AMRT mode and scroll down to enter 1 for [PM1] and 24 for [PM2]. Then, 
scroll to select [BAL:Solve] and solve it. 
 
 
 
 
 
The new loan duration will be calculated using this new outstanding balance where 
the monthly payment remains at $629.81 but the interest rate is now at  %10
12
=j . 
 
  To  find  the  changed  loan  duration  we  return  to  CMPD  mode,  enter  the  new 
outstanding  balance  as  PV  and  enter  10  for  [I%].  Note  that  the  new  outstanding 
balance is now stored in the Answer Memory. 
 
 
 
 
 Once these values are entered, scroll up to select [n] and solve it. 
 
 
 
Thus there are 265 more payment of $629.81 plus a final smaller payment. In other 
words  the  new  loan  duration  is  266  months,  or  total  is  24  +  266  =  290  months. 
Finally, we find the future value of the repayment with loan duration of 266 months; 
the difference between this future value and monthly payment is the final payment.    
 
 While in CMPD mode, enter 266 for [n], and scroll down to select [FV] and solve it. 
 
 
 
 
 Now calculate PMT + FV (FV is negative) at COMP mode. 
 
 
 
 
 
 
 
Therefore the final, smaller payment is $538.92. █
