They aren't advertising it, but as the title says you can pay down student loans with a credit card. For me, this means my 8% interest is getting cut down due to 2% cash back. I did a test payment and there was no fee. Thought y'all would like to know.
Key difference though is that student loan interest compounds daily, not monthly like other loans. And lender will apply prepayment when it's recieved, not hold it in escrow until a complete payment is recieved. (This same trick doesn't work for a mortgage, that amoritizes monthly).
Lemme look up my old spreadsheets and I can give my own loan as an example and show my math.
But maybe it's different now or depends on the lender. My student loan was during the Bush era when private student loan lenders were a thing... Loan was serviced by a company called Great Lakes and it was a variable rate loan tied to LIBOR index. During Obama they changed it back to federal loans only, and I'm not sure if that would nullify this. Think it's still relevant though but I could be wrong.
Those were the assumptions I used in the calculator, but I had forgotten that you still had to meet the minimum monthly payment, so you're paying at an advanced schedule. If you're paying 1/28th each day so you don't have to send an extra check in February that puts you at an even more advanced schedule.
