 * I must make an estimate of the total price of a product divided 24 installments.
   In this calculation we must add 5% for administrative expenses and interest at
   42% annually.
 * $administration = 5%;
    $spot_price = “X”; $Total_fees = 24; $interest = 42%;
 * $spot_price = total_price * $administration/100
    (In this calculation we must
   add the 42% interest)
 * please Help!!

 * Hi,
 * If the total price is fieldname1, and you need add to it the 5% for administration,
   and then add to it the 42% annually, and finally divided in 24 installments the
   solution would be similat to:
 * (fieldname1+fieldname1*0.05+fieldname1*0.42)/24
 * It is the same that:
 * fieldname1*1.47/24
 * If the annual interes is applied after the administrative expenses, the previous
   equation might vary drastically.
 * If you need additional support, we can offer you our custom formula services.
