Pay Off Debt or Start Saving First: How to Make the Decision

You have credit card debt and the start of a savings account and every article says something different. The correct answer depends on one number: the interest rate on the debt. This explains the comparison, the exception for emergency savings, and gives you a specific split for your monthly surplus so you stop defaulting to whichever feels better that week.
