Thanks, that worked great, I wasn't putting the negative infront of the
balance number which gave me a differnt number and changing it to a negative
after the fact messed it up worse. Thanks for your help, worked great.

I need a formula to calculate the number of payments remaining on a loan
based on constant interest, constant payments and a known balance. I am
trying to use the NPER function but it doesn't give the right answer if I
change the interest rate. How many payments do I have left on $16,000, with
5% interest, and $250 a month payment?


74.59215279

Or 74 Payments plus a balloon of about $147.55

Formula:

=NPER(0.05/12,250,-16000)
