Visual Basic loan interest and principal calculator
Posted 25 November 2012 - 09:34 PM
I'm trying to get the program to output the principal paid out to and the interest paid towards a loan of $5000. No input is take its all been declared already.Monthly payment is correct at 430.33. However, principal and interest output is (interest) 23.6588644... and -453.991013030... (which are flipped in placement). The output should be a row of principal reflecting the amount principal paid out through out the 12 months and a second row displaying also the interest paid towards the loan of 5000 through the 12 months. When i run the code with just the area below count+=1 and above the if statement only one output is displayed. I'm confused why with the loop the number get mixed up.
