I remember reading an article in some magazine where a reader asked “Is it better to contribute to my RRSP or better to pay off my student loans?”. The reader did not specify what their marginal tax rate was, which makes the calculations a lot easier.
I was floored to find out that the “expert” they had writing in the magazine actually recommended to pay off the minimum amount of their student loan and contribute the rest to their RRSP. The justification they gave is that the student loan interest is tax deductible so therefore it makes sense investing the proceeds into an RRSP where you can get more of a tax deduction.
This is the wrong line of reasoning. The ultimate decision might be correct depending on your income situation, but the reasons the author got there needs a little more explaining.
First, because the interest of a loan can be written off of taxes doesn’t mean that the loan is free – rather, the cost of the loan is reduced by the marginal tax rate. So if this hypothetical person was making between $40,000 a year, their marginal rate would be 31%. If they were paying 8% on their student loan, the after-tax cost would be about 5.5% (in a calculator, that’s 8% multiplied by 0.69, which is 100% minus 31%). Not a bad rate of interest, but certainly better than what you can get with a GIC (1-year rate is 3.75% at ING Direct).
Secondly, the tax deduction you receive from an RRSP can be realized at any point in time. If you contribute a dollar this year, you would get 31 cents back. If you contribute a dollar next year (assuming the tax brackets are the same), you still get 31 cents. You can even contribute a dollar this year and claim it next year. In other words, you can receive that 31 cents at any time. Yes, the money inside an RRSP compounds over time and also that a dollar received today is worth more than a dollar received tomorrow, but it only makes financial sense if you think you can get more than a 5.5% return out of the RRSP. People would have to make good choices to realize that return.
5.5% isn’t a huge amount, but it’s enough to seriously consider just throwing the money back into the student loan debt since it’s a guaranteed after-tax return of 5.5%. It’s infinitely better than throwing the money into a GIC, whether it’s tax sheltered or not. There is also the other intangible consideration of being able to finally say that you’re debt free – I personally abhor debt. Debt forces people to worry about it, and I hate worrying about things.
The numbers say that you can probably achieve a better than 5.5% return, but this sort of justification is very weak in the context of debt management. It’s just best to pay it off since you won’t have to again.
If this hypothetical person makes less than $35500 a year (2005 tax year), they are in a lower tax bracket (21%) and then the cost of the 8% loan rises to 6.3%. In this case, it’s a total no brainer to pay off the student loan first and worry about the RRSP later if and when the person rises into the next income bracket.
I’ve always maintained that anybody in the lowest income tax bracket should not bother investing in RRSPs – income received from dividends and capital gains are so low outside an RRSP that tax-free compounding is minimal at the lowest rate of taxation. In addition, the tax savings realized are not very high.
The conclusion is that the magazine author was probably wrong – I’d pay off as much as your student debt as you can and worry about an RRSP and savings later in life, specifically, when you’re out of debt.
