That depends if it's fixed rate debt or not. Fixed rate debt that came about over the last decade is often accruing interest at a lower rate than you can reasonably get with some fairly safe instruments, be they treasuries, money markets, or some more exotic fixed income securities. If you're paying down debt financed at 5% and getting a 7% return on your savings, it's a non-trivial decision to pay it down any faster than you absolutely have to. I'm sure in no rush to pay down my car loan any quicker than is required.
