payment for a 9,000 dollar loan at 4.95% for 72 months

If this is to be one payment after 6 years using simple interest, use the simple interest formula:  I = Prt

I = interest          P = principal (amount borrowed)         r = rate (as a decimal)        t = time

--->     I  =  (9000)(.0495)(6)  =  $2673.00

So, the amount owed is $9000.00 +  $2673.00  =  $11,673.00

If you want a monthly payment amount, you will need to repost and ask for that ...
