My Situation:
About $36k USD in graduate student loans.
There are 4 different federal loans in play, each with a fixed rate of 6.8%.
$12k w/ ~$1.2k in unpaid interest
$10k w/ ~$1k in unpaid interest
$8k w/ no unpaid interest (all principal)
$6k w/ no unpaid interest (all principal)
All loans are in repayment.
Some loans are subsidized, some are not. This no longer matters now that they're all in repayment though, right?
Is there a most cost efficient way to pay these loans off?
Should the interest be ignored for now on the ones that have $1k in unpaid interest for the time being, because payments to the other two loans will will go directly to principal (minus the monthly compounded interest of course)?
On the surface, I would assume that since they're all the same interest rate, it doesn't really matter, but I'm not sure how the accrued interest would factor in. I'm not interested in psychological wins like debt snowballing. I'm looking for the route that will have me paying the least.
