Warren Buffett’s investment philosophy may apply to more than just picking stocks. Some experts now say the same approach can work for choosing credit cards and their perks.
Chris Fred, TD Bank’s head of credit cards and unsecured lending, suggests that the strategy behind Buffett’s famed “circle of competence” concept can guide credit card selection. The idea involves sticking to what you understand and leaving complex decisions to those better positioned to make them.
“Just like Warren Buffett says to buy the index fund, a good flat-rate card often wins out over all the fancy bonus categories,” Fred said.
The Case for Simple Credit Card Strategy
For those with deep knowledge of credit card rewards, opening multiple cards with various bonus categories can maximize returns. However, for the average consumer, tracking which card to use at which merchant often creates more hassle than value.
Fred noted that the r/churning subreddit, dedicated to maximizing credit card rewards, even advises most people against attempting intensive reward maximization. “People think, ‘I can always beat that 2%.’ On average, they don’t,” Fred said.
Consider a premium card offering 4x on dining but only 1x on pharmacies and basic goods. The 3x on groceries and 1.5x on travel may exceed 2% cash back elsewhere, but these gains get offset by lower earning rates in other categories. Cardholders then find themselves needing spreadsheets to track optimal usage, when a simple 2% flat-rate card would provide comparable returns without the mental effort.
Annual Fees Add Complexity
The points versus cash-back debate becomes more complicated when annual fees enter the picture. Premium cards can cost nearly $1,000 per year but market themselves as offering thousands in perks provided cardholders actually use them.
“The higher the fee, the more benefits you tend to have,” Fred said. “It’s a dangerous proposition: You’d better start using those benefits, or it’s going to be really hard to justify the fee.”
These cards often require opt-in for credits rather than automatically applying them, designed to reduce usage while maintaining customer retention. “Those customers are sticky. They’re spending a certain amount each year in annual fees, so they’re vested,” Fred explained.
Finding Your Strategy
For those comfortable managing multiple cards and tracking categories, tiered rewards cards can provide value. For everyone else, a straightforward flat-rate card offers reliable returns without complexity. The key is honest self-assessment: know whether the effort required matches the potential benefits.
