This question already has an answer here:
I have two student loans I would like to pay off:
A: $6000 - 6.5%
B: $3000 - 6.5%
I am receiving a tax refund of a bit over $3000. I am not sure whether to pay off B in one fell swoop to get it out of the way, or to halve the principal of A, reducing the total interest I pay over time.
I also have two additional loans of similar principal and half the interest rate for each. I am not sure how, if at all, they factor into this decision.
