Rotating or chosen categories? Freedom Flex vs Discover it vs Customized Cash

Chase Freedom Flex and Discover it Cash Back pay 5% on categories the issuer picks each quarter. Bank of America Customized Cash Rewards pays 3% on a category you pick yourself. Run the caps and each card’s capped bonus rate tops out at the same $300 a year, before any Preferred Rewards boost (the Flex’s uncapped 3% on dining and drugstores comes on top), so the choice comes down to three things: how much spending you can steer, whether you will activate every quarter, and whether you already bank with Bank of America.

How Freedom Flex, Discover it and Customized Cash earn

The three have more in common than their marketing suggests. None charges an annual fee, all three pay 1% outside their bonus categories, all three open with a 0% intro APR of about 15 months, and our catalogue lists the same 670-850 recommended score range for each. The differences are who chooses the bonus category, how much spending the bonus covers and what comes attached.

Chase Freedom Flex: a rotating 5% on top of fixed categories

The Flex pays 5% on rotating quarterly categories on up to $1,500 a quarter after activation, 5% on travel booked through Chase Travel, 3% on dining and drugstores and 1% on everything else. Activation applies only to the rotating 5%, so the 3% on dining and drugstores keeps paying in quarters when the rotating categories miss you. The welcome offer is $200 after $500 in purchases in the first 3 months. It is a Mastercard with cell phone protection and purchase protection, rated 4.5 on this site.

Its rewards also pair with Chase’s Sapphire cards. Points moved between your own Chase cards generally pool together, and the Chase Sapphire Preferred lists 25% more value on travel booked through Chase Travel. At the 1.25 cents a point that implies, the rotating 5% is worth 6.25 cents a dollar. That takes a $95 card and travel redemptions, and the Chase trio runs those numbers. Everything below values Flex rewards at 1 cent, as plain cash back.

Discover it Cash Back: one rotating category and a first-year match

Discover keeps it to two rates: 5% on rotating quarterly categories on up to $1,500 a quarter after activation, and 1% on everything else. There is no upfront bonus. Instead, Discover automatically matches all the cash back you earned at the end of your first year, with no cap. It lists no foreign transaction fees and a free FICO score in the app, but Discover acceptance is narrower than Visa or Mastercard abroad. Its 4.6 rating is the highest of the three, and our Discover it pros and cons weighs it on its own.

Bank of America Customized Cash Rewards: you choose the 3%

Customized Cash pays 3% in a category you choose and 2% at grocery stores and wholesale clubs, on up to $2,500 of combined purchases a quarter, then 1%. You can change the 3% category once a month; Bank of America sets the menu, so check its current list. The welcome offer is $200 in online cash rewards after $1,000 in purchases in the first 90 days, and Preferred Rewards members earn 25% to 75% more. It is a Visa, rated 4.3.

The cap math: why all three capped bonus rates top out at $300 a year

Headline rates hide the ceiling. Five percent on $1,500 a quarter and 3% on $2,500 a quarter produce the same maximum: $75 a quarter, $300 a year. What differs is how much spending it takes to get there, and how much of that $300 you would have earned anyway at 1%.

Two consequences follow. The rotating cards squeeze more out of less: $240 above the base rate on $6,000 of spending, against $200 on $10,000 for Customized Cash. And Customized Cash’s cap is shared. Grocery dollars at 2% use room the 3% category could have had, so a household with $600 a month of groceries, $1,800 a quarter, has $700 a quarter left for its 3% category before everything drops to 1%.

The rotating ceiling is the less reliable one. You reach $1,500 in a quarter only if that quarter’s categories cover enough of what you already buy. Chase and Discover set their calendars independently and change them every quarter. The categories have commonly been everyday ones such as grocery stores, gas stations and restaurants, but a quarter that features something you rarely buy pays you nothing extra. Customized Cash’s ceiling takes more spending to reach, but you know in advance where the 3% will land.

Freedom Flex vs Discover it vs Customized Cash for one household

To compare like with like, take one hypothetical household spending $2,000 a month, $24,000 a year, split into five lines. Each dollar sits in exactly one line.

• $400 a month in the quarter’s 5% categories. Not a kind of purchase, but the slice of spending that happens to fall in whatever is featured, taken out of the other lines. That is $1,200 a quarter, under the $1,500 cap.
• $200 in a category Customized Cash would pay 3% on, other than dining and groceries.
• $300 on dining and drugstores.
• $400 at grocery stores and wholesale clubs.
• $700 on everything else.

Three things stand out. The Flex leads because its 3% on dining and drugstores adds $72 over Discover without any effort. Customized Cash is the only card whose result does not fall when attention does. And the flat 2% card beats two of the three outright.

The 2% test: why these work best as a second card

All three pay 1% outside their bonus categories, half what a flat 2% card pays. On its own, only the Flex beats Double Cash for this household, by $24, and only with every activation done. The stronger setup gives the category card only the purchases that earn a bonus and puts the rest on a flat 2% card.

Category cash back calculator: rotating 5% vs chosen 3%

Rotating categories cannot be modelled precisely, because nobody knows next year’s calendar. The calculator treats them as a separate line: the monthly spending you expect to land in featured categories, averaged across the year. Be honest with that number. It is the whole case for the Flex and Discover, and it is zero in any quarter you forget to activate.

At the defaults, which are the example household, the Flex leads the three and Customized Cash trails. Move the rotating line’s $400 into everything else, which is what never activating means, and Customized Cash overtakes both rotating cards, with the 2% card ahead of all of them. Push the rotating line past $500 a month and the extra earns 1%: that is the $1,500 quarterly cap.

Bank of America Preferred Rewards: the boost that reorders the ranking

Customized Cash has one lever neither rotating card can match: Preferred Rewards members earn 25% to 75% more. Membership generally depends on the balances you keep across Bank of America and Merrill accounts; confirm the tiers and requirements on Bank of America’s own page. Applied to everything the card earns, as our catalogue’s wording reads, the rates move like this.

At the top of the range, the chosen category pays 5.25%: more than the rotating 5%, with no activation and on a cap that holds $1,000 more spending a quarter. Everything else pays 1.75%, close to a flat 2% card. For the example household, 25% more lifts Customized Cash from $336 to $420, still behind the Flex’s $504. The tie comes at 50% more ($336 × 1.5 = $504). At 75% more it earns $588, ahead of every card here used on its own in every year after the first.

Activation and the cost of forgetting

On both the Flex and Discover, the 5% applies only after you activate, and activation generally has to be repeated every quarter. Miss it and those purchases earn 1%. Issuers set their own activation windows and their own rules on whether purchases made before you activate count, so check each quarter’s terms rather than assuming a grace period.

The forgetful fare differently on each card. A Flex holder who never activates still collects 3% on dining and drugstores. A Discover holder who never activates has a 1% card from year two. Customized Cash fails more gently: the category generally stays where you set it until you change it, so neglect costs nothing unless your spending drifts away from it.

Welcome offers: two $200 bonuses against an uncapped match

The Flex pays $200 after $500 in purchases in the first 3 months, about $167 a month. Customized Cash pays $200 after $1,000 in the first 90 days, about $333 a month. Discover pays nothing upfront and matches all the cash back you earned in the first year, automatically, at the end of that year.

The match beats a $200 bonus whenever you earn more than $200 on the card in year one. Filling the 5% cap every quarter earns $300 by itself; at 1% alone it takes $20,000 of spending. For twelve months the match also changes the card’s shape: 10% on up to $1,500 a quarter in the rotating categories, and 2% on everything else.

In year one, Discover is a 2% card with 10% categories.

Intro APR, travel abroad and the fine print

All three open with a 0% intro APR: 15 months on the Flex and Discover, 15 billing cycles on Customized Cash, roughly the same window. After it, the variable ranges are 19.99% to 28.74% on the Flex, 18.24% to 27.24% on Discover and 18.24% to 28.24% on Customized Cash. Discover ties Customized Cash for the lowest starting rate and has the lowest top rate. None of that rescues a balance you carry: 18.24% on $2,000 is about $365 a year, more than any of the three pays in bonus cash at standard rates.

Abroad, Discover lists no foreign transaction fees, but its acceptance is narrower than Visa or Mastercard outside the U.S. The Flex runs on Mastercard and Customized Cash on Visa; our catalogue lists no foreign-fee terms for either, so check the issuer’s page before counting on them abroad. The Flex adds cell phone protection and purchase protection; Discover adds a free FICO score in the app.
