Quick loan question: Specifying to principal vs pre-payment

The g/f has a brand new car loan that she's getting ready to make the first payment on. It's a 48 month loan, but she'll be paying it off in a year or so. Small loan, high income, etc. Anyway...

Apparently the bank requires her to send a separate check to a different address if she wants to make payments directly to principal. Excess payments otherwise go to pre-payment, ie pushing the due date of the next payment out beyond a month.

The question:

Assuming she continues to pay it off at this accelerated rate there is no financial advantage to either method... Correct? There is no pre-payment penalty, so total interest for each cycle (or between each payment) will be daily rate * principal * days in cycle.

My gut feeling says the end cost will be identical, & she doesn't need to bother with the 2nd check to principal nonsense. Unfortunately I don't know an easy way to prove it.

Extra payments to principal = less principal to pay interest on.
Prepayment = principal stays the same, just making payment ahead of time, so still paying interest on that principal.

Extra payments to principal will save a substantial amount of money.

I think you'll want to talk to the lender about that.

Prepayment just sounds like it will push back the next due date and not alter the amortization schedule.

So if they're not altering the amortization schedule they would owe her a small interest refund at the end of the loan.

I guess that means there is a very small advantage to specifying payments to principal: you don't let them hold your excess interest at 0%.

I think you're right.
