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. Read on to find out which card shines in the most important categories cardholders care about.

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 among all cash back credit cards on the market today.

In comparison, Bank of America Unlimited Cash requires you to spend $1,000 on purchases within 90 days to earn the $200 online cash bonus. That said, 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 America Preferred Rewards member, in which case you’ll earn 25 percent to 75 percent more in cash back on all your purchases depending on your membership level.

Tiers are based upon your combined three-month balance across qualifying Bank of America and Merrill investing accounts. Just remember that you’ll have to have at least a $20,000 balance in qualifying accounts to qualify for the lowest tier of this program, which will earn you 25 percent more rewards. You need a minimum of a $100,000 balance across accounts to earn 75 percent more rewards. As a result, many people won’t be able to take advantage of this program and the benefits it offers.

Annual fee winner: Tie

Like many cash back cards, neither the Capital One Quicksilver card nor Bank of America Unlimited Cash 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 card doesn’t charge foreign transaction fees on purchases made outside of the U.S. or in foreign currency, whereas the Bank of America Unlimited Cash charges a 3 percent foreign transaction fee.

Intro APR winner: Tie

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 for the first 15 billing cycles (15 months with the Capital One card). After this introductory period, the Bank of America card has a slight advantage with its variable APR of 18.24 percent to 28.24 percent (compared to 19.99 to 29.99 percent with the Capital One card).

Note, however, that with the Bank of America card, balance transfers must be made within the first 60 days to qualify for the intro offer and an intro 3 percent balance transfer fee applies, then 4%. The Capital One Quicksilver, on the other hand, does not have this timing limitation, but does also have a 3 percent transfer fee on promotional APR balance transfers.

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 Diamond
Minimum balance required $20,000 $50,000 $100,000 $1 million
Rewards bonus 25% 50% 75% 75%
New cash back rate 1.87% 2.25% 2.62% 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 Bank of America 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
  • Diamond (75 percent boost): $52.40

Now let’s imagine your spending and rewards remain stable over the course of a year. The chart below shows how much you would earn in rewards on $2,000 in monthly spending with the Bank of America Unlimited Cash Rewards as a member of Bank of America Preferred Rewards vs. Capital One Quicksilver:

Rewards for $2,000 in monthly spending Rewards for $24,000 in annual spending
Capital One Quicksilver Cash Reward or Bank of America Unlimited Cash $30 $360
Bank of America Unlimited Cash (with Gold membership in Preferred Rewards) $37.40 $448.88
Bank of America Unlimited Cash (with Platinum membership in Preferred Rewards) $45 $540
Bank of America Unlimited Cash (with Platinum Honors membership or better in Preferred Rewards) $52.40 $628.80

While the rewards offered through the Bank of America Preferred Rewards program are attractive, keep in mind that you need a minimum of $20,000 in qualifying accounts with the bank to even join this program, and that earning the highest bonus of 75 percent more rewards requires six figures.

And even though the Bank of America Preferred Rewards program offers a nominal “boost” on savings rates for members, their starting rate on savings accounts is a disappointing 0.01% APY to begin with. This is much less than you’ll earn with the best high-yield savings accounts, which currently offer rates of around 5.00% APY.
