Maybe other things about them are good, but the interest rate is too high. The majority of my federal student loans are like 6.8%. I could go get a car loan at a much lower rate, which is kind of messed up that a shorter term loan for a car is much lower interest rate than a loan for college.
But a car loan has several things going for it.
1. Most car loans at that rate are for prime borrowers where they default less than 1% over the lifetime of their loans.
2. Captive auto loans are supported by the manufacturer (subvention), thus, the cost of the loan is built into the car.
3. How is it messed up that a shorter term car loan is cheaper? Term structure of interest rates dictate that longer termed rates are higher to compensate the investor for the likelihood that rates will increase, plus the longer period the money is locked up. That's why a 30 year mortgage has a more expensive rate than a 15 year mortgage, duh.
4. Car loans are secured. Thus, at the proper LTV, a lender can get most, if not all, of their principal back. Student loans are not secured.
5. Car loans are underwritten to FICO score, ability to repay, and likelihood to default, using statistical modeling, most likely incorporating hundreds of variables such as time-on-job, homeownership, DTI, PTI. Some auto lenders incorporate dozens, if not hundreds, of variables into their scorecards to determine loss rates and set an appropriate down payment and interest rate. Student loans possess none of these factors.
6. Student loans are ultimately far riskier. The current "Cohort default rate" is running at 17%+ and I personally believe that is massively understated. Severely delinquent loans make up ~40% of the loan population, once you adjust for the fact that only 40-50% of all loans are actually in repayment.
By way of comparison, deep subprime auto loans have net default rates of ~25-30% with severities of 50-70%. That means that gross default rates are 50-60%, if not 40-50%. So student loans perform only slightly better than 520 WA FICO subprime auto loan pools.
There is absolutely no reason that student loan rates should be lower.
The 20 year treasury is ~2.18%. Servicing that loan maybe costs 2% per year. That leaves ~2% in "excess spread" pear year. Now, the WA life of the student loan is ~10 years (amortizing loan), that means that the loan will generate ~20% of excess spread for the entire life of the loan. That's assuming that *all* loans are current and you collect all of that interest. It doesn't take into account forbearance, deferment, grace, or anything else that may result in non-collection of interest.
Even at that, for the *entire* life of that loan pool, you only make 3% (assuming 17% defaults) 20% - 17%, of actual "revenue" from the interest/excess spread.
I could *easily* come up with factors that eliminate that 3%, including the aforementioned grace/deferment/forbearance which results in loss of excess spread, delinquent loans which then go defaulted without payment of that interest...etc.
There is no room for reduction in interest rate, unless you recognize that loans are a losing proposition and are ok with that.
