Debt Consolidation - Anyone ever take advantage of this?

I didn’t really want to do this but I will anyway. it’s not a big deal.

Credit cards:
$4,222 on one @ %9.24 $390.11 a year interest I have 37 payments left to make. So 3 years
$259 on the other @ %24 $62.16 a year interest forget this its paid off this month.

school loan:
$5,965 @ %3.37 $201.02 a year interest. I have 74 payments left to make. So 6 years

car payment:
$11,130 @ 8.99% $1000.58 a year interest I have 34 payments left to make. So 2.8 years

So take the car payment 34 months left and lets use this as the projected time to pay off the above debts. $21317 total If I took that and projected to pay it off in 34 months, I would pay about $3197 in interest @ %5.

If I left it as is, in order I would pay $1170, $1200 & $2801 in the time it would take to pay them off. Total of $5171 in interest over 6 years.
