The Capital One Quicksilver Cash Rewards Credit Card and the Bank of America® Unlimited Cash Rewards credit card both come with no annual fee and offer 1.5 percent cash back on all purchases. But which card is better for you?

If you’re a Bank of America Preferred Rewards member, then the Bank of America Unlimited Cash may be more valuable to you. On the other hand, if you’re looking for a straightforward card that earns a high cash back rate without having to jump through a lot of hoops, the Capital One Quicksilver may make more sense for you.

Capital One Quicksilver vs. Bank of America Unlimited Cash highlights

Both of these top cash back cards come with no annual fee, unlimited cash back on all purchases and 0 percent intro APR offers, but they vary in some areas like their welcome bonuses.

Welcome bonus winner: Capital One Quicksilver

Both cards offer a $200 welcome bonus, but the Capital One Quicksilver only requires you to spend $500 on purchases within the first three months to earn the bonus. The $500 spending threshold is easy to meet, and one of the lowest spending limits you’ll find.

In comparison, the Bank of America Unlimited Cash requires you to spend $1,000 on purchases within 90 days to earn the $200 cash bonus. Additionally, it’s worth noting that a $200 welcome bonus is on par with other cash rewards cards that don’t carry an annual fee.

Rewards rate winner: Tie

Both cards offer an unlimited 1.5 percent cash back on all purchases, so they tie in this category. The exception to this tie is if you’re a Bank of American Preferred Rewards member, in which case you’ll earn 25 percent to 75 percent more in cash back depending on your membership level.

Annual fee winner: Tie

Like many cash back cards, both the Capital One Quicksilver card and the Bank of America Unlimited Cash don’t charge an annual fee. Either card is ideal if you’re trying to keep a yearly fee from eating into your rewards earnings.

Foreign transaction fee winner: Capital One Quicksilver

The Capital One Quicksilver doesn’t charge foreign transaction fees on purchases made outside of the U.S., whereas the Bank of America Unlimited Cash charges a 3 percent foreign transaction fee.

Intro APR winner: Bank of America Unlimited Cash

Both the Capital One Quicksilver card and the Bank of America Unlimited Cash card offer a 0 percent intro APR on purchases and balance transfers, but the Bank of America Unlimited Cash offers a slightly longer intro period.

The Bank of America Unlimited Cash offers a 0 percent intro APR for 18 billing cycles on purchases and qualifying balance transfers (then a variable APR of 17.49 percent to 27.49 percent). Additionally, note that balance transfers must be made within the first 60 days to qualify for the intro offer and a 3 percent balance transfer fee will apply.

The Capital One Quicksilver, on the other hand, offers a 0 percent intro APR for 15 months, followed by a variable APR of 19.24 percent to 29.24 percent.

Which card earns the most?

If you’re looking for an unlimited 1.5 percent cash back on all purchases, the Capital One Quicksilver and the Bank of America Unlimited Cash both fit the bill. Either card may make sense if your purchases often fall outside the usual card bonus categories, such as bill payments or certain types of online retail purchases.

If you already use a rotating category card to maximize cash back in specific bonus categories, either of these flat-rate cards would be a good complement. They’ll both offer you 1.5 percent back on non-category purchases instead of the baseline 1 percent back typically offered for general purchases on other cards.

So, which card earns the most? On their own, the cards are tied. However, there is one notable difference: Bank of America customers who belong to Bank of America’s Preferred Rewards program can get a 25 percent to 75 percent rewards boost on top of their Bank of America Unlimited Cash’s 1.5 percent cash back rate.

The Preferred Rewards program tiers are based on the combined three-month average balance of your Bank of America and Merrill accounts. For the Bank of America Unlimited Cash, here is the new cash back rate you’d earn for each rewards tier:

Gold Platinum Platinum Honors
Minimum balance required $20,000 $50,000 $100,000
Rewards bonus 25% 50% 75%
New cash back rate 1.87% 2.25% 2.62%

As the tier bonus structure reveals, if you’re a Preferred Rewards member with $50,000 or more across all of your accounts, then the Bank of America Unlimited Cash card’s cash back rate of 2.25 percent is better than almost all flat-rate cards, which typically offer a maximum rate of 2 percent back on general purchases.

Capital One Quicksilver vs. Bank of America Unlimited Cash spending example

On their own, both the Capital One Quicksilver Cash Rewards and the Bank of America Unlimited Cash Rewards cards deliver a flat 1.5 percent cash back on all purchases. So, for example, whether you spend $100 per month or $1,000 per month, both cards will earn either $1.50 or $15 (respectively) in cash back. But, as demonstrated above, you can boost your cash back rewards significantly with the Bank of America Unlimited Cash if you are a Bank of America Preferred Rewards member.

For example, say you spend $2,000 on purchases during a billing cycle. At a rate of 1.5 percent cash back, you’d earn $30 back with either the Capital One Quicksilver or the Bank of America Unlimited Cash. However, if you are a Bank of America Preferred Rewards member, you could boost your rewards earnings further on that $2,000 in purchases with the Bank of American Unlimited Cash. For each tier, you could earn a total of:

  • Gold (25 percent boost): $37.40
  • Platinum (50 percent boost): $45
  • Platinum Honors (75 percent boost): $52.40
