High Speed Debt Elimination

Over the past couple of years, I have been on a mission to eliminate all non-income producing debt from my life (besides mortgage). When I first started this mission, I had not only a ton of credit card debt but also a decent amount of installment debt. This mix made it difficult to figure out which debt I should pay off first.

To come up with an answer, I first looked at the most important factors in deciding which debt payoff would be most beneficial:

Rate

This is one of the obvious factors. If you have a credit card at 14.99% and another at 9.99%, you should pay the higher rate down first. This minimizes the amount of debt you will pay in the long run.

It is a bit more complicated to compare the rate of credit card debt to installment debt, because the overall effect of paying them down is not the same. The impact of a payment to the interest that is accrued is similar with each type of debt (all else being equal), but the amount of the next payment will be lowered on the credit card and not the installment debt. This leads me to the next factor
