On the other hand, the ETF is pro-rated, and it goes down by $5 for every month that you are into your contract. So, $175 - 18 x $5 = $85 which you will still owe them if you jump ship at that point in time.
That is not being prorated - it is being discounted. A prorated ETF for a 24 month contract that is reduced by $5 a month would be only $120. If it starts at $175 the correct PRO-RATED reduction per month is $7.30.
