How To Convert Capital One Cash Back Into Miles

So, you’ve got a Capital One card — maybe a couple. You’re earning rewards, but they’re split into two mysterious buckets: Capital One Cash Back and Capital One Miles. And now you’re wondering, “Wait... can I just combine these into one big travel pot?”

Yep. You can. And you should!

This little trick can turn your everyday coffee runs and grocery trips into flights, hotel stays, and the kind of travel wins that make friends ask, “How are you affording this?”

Getting Started: Know Your Cards

Capital One has two main types of cards:

• Cash-back cards that earn Capital One cash back rewards — straightforward, dollars-in-your-pocket style

• Miles cards that earn Capital One miles rewards — flexible points you can use for travel

Here’s the twist: “miles” aren’t airline miles. They’re just Capital One’s way of saying “travel points,” and they’re much more versatile than plain cash-back... especially once you know the secret to combining them.

Miles-Earning Cards (The "Travel" Crew):

These are the heavy hitters that turn rewards into plane tickets and hotel stays:

• Capital One Venture X Rewards Credit Card

• Capital One Venture X Business 

• Capital One Venture Rewards Credit Card

• Capital One VentureOne Rewards Credit Card 

• Capital One Spark Miles for Business

Cash-Back Cards (The "Daily Spending" Squad):

These cards earn cash back on your everyday purchases. This is the rewards currency you'll be converting to miles:

• Capital One Savor Cash Rewards Credit Card

• Capital One Quicksilver Cash Rewards Credit Card

• Capital One Spark Cash Plus

How to Combine Your Rewards

Once you’ve got the right cards, combining your rewards is simple:

1. Log in to your Capital One account from a desktop browser (you can’t complete this process in the mobile app).

2. Go to Rewards.

3. Click Combine Rewards.

4. Pick your cash-back card as the from account, and your miles card as the to account.

5. Select the amount you want to convert.

6. Confirm the transfer… and boom — your miles will appear instantly.

The conversion is a straightforward one cent of cash back for every one Capital One mile. This means $100 in cash back becomes 10,000 miles, instantly boosting your travel fund.

However, it is important to note that you cannot transfer miles to cash back at the same rate, so keep that in mind as you’re combining!

Looking to combine business with personal rewards? Capital One makes it easy, allowing cardholders to combine points between business cards like the Venture X Business and the personal Capital One Quicksilver with no additional hurdles.

Redeem for Maximum Value

With your newfound stash of Capital One Miles, you have a few options for redemption. While you can redeem them for a statement credit or gift cards, the highest value comes from redeeming for travel.

You can use your miles to:

• Book through Capital One Travel: Log in, search for flights, hotels, or rental cars, and check out using miles. You’ll get a steady one-cent-per-mile value, plus perks like price drop protection and built-in cancellation options. Easy and stress-free.

• Transfer to Travel Partners: Here’s where the magic happens. Many Capital One airline and hotel partners transfer at a 1:1 ratio, meaning your miles can stretch way further.

  • Example: Transferring 50,000 miles to Air Canada Aeroplan could land you a $2,000 business-class flight to Europe. That’s a four-cent per mile value (literally quadruple what you’d get by redeeming them for cash back!).

Bottom Line

Combining Capital One rewards is like combining peanut butter and chocolate — they’re great alone, but together? Chef’s kiss. 🤌

But here’s the best part: when you convert cash back into miles and use them strategically, you’re not just saving money, you’re opening the door to trips you might’ve thought were out of reach.

It’s peanut butter and chocolate... on a business class flight to Paris.
