Dear Liz: I have about $16,000 in student loans at 6.8% interest. At the current monthly payment it would take me about 7.5 years to pay them off. I contribute 10% of my income to my company’s Roth 401(k) plan (my employer matches the first 6% contributed). I also contribute 3% to the stock purchasing plan. I am thinking of cutting back my 401(k) contribution to 6% and not contributing to the stock purchasing plan. Applying the extra money to my loans would reduce the payback period to about 2.5 years. After that, I would increase the contribution amount and diversify with a Roth IRA as well and maybe even begin the stock purchase program again. What do you think?
Answer: Not contributing to retirement accounts is usually an expensive mistake. The younger you are, the more expensive it can be.
Every $1,000 not contributed to a retirement plan in your 30s means about $10,000 less in retirement income. That assumes an average annual growth rate of 8%, which is the historical average for a stock-heavy portfolio.
In your 20s, the cost of not contributing that $1,000 is $20,000 of lost future retirement income. The extra decade of not getting those compounded returns makes a big difference.
People have the erroneous idea that they can put off retirement savings and somehow catch up later. Catching up, though, becomes increasingly difficult the longer you wait. A better approach is to save as much as possible starting in your 20s when the money has the longest time to grow. Then you’ll be in a better position to withstand job losses or other interruptions of your ability to save. If those setbacks don’t happen, you’d have the option of retiring early.
Granted, your plan would require reducing retirement contributions for just a few years. But the federal student loans you have are fixed-rate, tax-deductible debt that you don’t need to be in a hurry to pay off. In the long run, you’d be much better off boosting your retirement contributions.
If you’re determined to pay down your loans, however, use the money you’ve been contributing to the stock purchase plan. Continue making at least a 10% contribution to your retirement plan and increase that as soon as you can.
