Do people tend to spend less when using cash than credit cards?
Unless a study accounts for whether the users are following a budget or not, it is irrelevant to those who are trying to take their personal finances seriously. I can certainly believe that those who have no budget will spend more on a credit card than they will on a debit card or with cash. Under the right circumstances spending with cards can actually be a tool to track and reduce spending. If you can see on a monthly and yearly basis where all of your money was spent, you have the information to make decisions about the small expenses that add up as well as the obvious large expenses.  Debit cards and credit cards offer the same advantage of giving you an electronic record of all of your transactions, but debit cards do not come with the same fraud protection that credit cards have, so I (and many people like me) prefer to use credit cards for security reasons alone. Cash back and other rewards points bolster the case for credit cards over debit cards. It is very possible to track all of your spending with cash, but it is also more work. The frustration of accounting for bad transcriptions and rechecking every transaction multiple times is worth discussing too (as a reason that people get discouraged and give up on budgeting). My point is simply that credit cards and the electronic records that they generate can greatly simplify the process of tracking your spending. I doubt any study out there accounts for the people who are specifically using those benefits and what effect it has on their spending.
