I am going to grad school in Canada this September and have a chance to borrow ~$15000 at a rate of prime+1% (provincial loan) and prime+2.5% (federal). I would guess the 15000 is split 50-50 between provincial and federal governments - but I am assuming it's all federal.
This mean I get $15000 at (
2.7 + 2.5 = 5.2)%. I don't spend a lot, and keep most of my money in a mutual fund that has returned ~6% in the past year. Is it better to take this student loan even if I don't need it?
