My lump sum payment is much less than the same payment divided by the term. This is becasue I am financing this amount over the period of the term. As I said, in KY, I pay 6% on the entire monthly payment, which includes and "finance charge" payment or interest. This ups the cost of using that money over time significantly. I can do better by paying on lump sum up front, than paying an additional 6% on my financinf the use of the money over time. Compare teh single paymnet to the sum of teh payments over time, and you will see how much this financing really costs youo. Then add 6% to the total of those payments over time vs 6% on the single payment, and you are losing money.
