Capital One Spark Cash Plus Review
Overview
The Capital One Spark Cash Plus is a strong flat-rate business card: 2% cash back on everything, no preset spending limit, and a fee that can be refunded if you spend enough. For a business that wants simple, high, uncapped cash back, it is one of the best options around.
It is a charge card, so you pay it in full each month, but the flat 2% with no categories and a huge welcome bonus makes it a clean, powerful earner.
Think twice if: you want transferable points, since the Spark cash cards pool to miles only if you also hold a Venture card.
Our 4.0 out of 5 rating
Each score weighs the rewards rate, value after the annual fee, welcome offer, points flexibility, and perks, with every point valued at a flat 1 cent. This is our editorial assessment to help you compare cards, not a guarantee of approval or of the value you will get.
Rewards: how it earns
You earn a flat 2% on everything with no categories and no cap, as cash back. For a high-spending business, uncapped 2% on all spending is excellent, and the rewards can be pooled into transferable miles if you also hold a Venture card, which adds flexibility.
| Category | Rate | Notes |
|---|---|---|
| Dining and restaurants | 2% back | Base rate |
| Groceries | 2% back | Base rate |
| Gas | 2% back | Base rate |
| Travel | 2% back | Base rate |
| Streaming | 2% back | Base rate |
| Everything else | 2% back | Everything else |
Brand and bonus rates: beyond the everyday categories above, this card also earns:
- 5% cash back on hotels and rental cars via Capital One Travel
The fine print on rates: A charge card paid in full each month. The $150 annual fee is refunded every year you spend at least $150,000. Cash back converts to transferable miles 1 cent to 1 mile if you also hold a Venture, Venture X, or Venture Business card.
Every point and mile above is valued at a flat 1 cent, the same honest standard we use for every card. Run your own spending through the calculator to see what this card would actually return for you.
Pros and cons
- Flat 2% on everything, uncapped
- Fee refundable with enough spending
- Large $2,000 welcome bonus
- Rewards can pool to miles with a Venture card
- Charge card, must pay in full each month
- Counts toward Chase 5/24
- Large welcome-spend requirement
The welcome bonus
The welcome bonus is large: $2,000 cash back after $30,000 in three months. A big year-one payout, though it requires serious spending to unlock.
Is it worth the annual fee?
The $150 fee is refunded if you spend enough each year, so for a high-volume business the card can effectively be free. As a charge card you must pay in full monthly. Capital One business cards count toward Chase 5/24, so plan accordingly.
First-year value vs ongoing value
| Welcome bonus | $2,000 cash back |
| To earn it | $30,000 in 3 months |
| Est. first-year value* | $2,750 |
| Est. ongoing value / yr* | $750 |
The welcome bonus makes year one the high point: roughly $2,750 in value once you count the bonus, this card’s rewards, and its credits, minus the $150 fee. After that, the honest figure is about $750 a year, so judge whether it earns its keep on the ongoing number, not the first-year headline.
*First-year value counts the welcome bonus, estimated rewards, and annual credits, minus the annual fee; ongoing value is a typical year after. Every point at a flat 1 cent, on average spending.
Benefits and protections
Beyond the rewards, the perks and protections worth knowing about include:
- No preset spending limit (balance paid in full monthly)
- $150 annual fee refunded every year you spend $150,000
- Free employee cards
- No foreign transaction fees
Statement credits
This card does not come with recurring statement credits. Its value is in the rewards rate and welcome offer.
Ecosystem and transfer partners
The Capital One Spark Cash Plus earns Miles, one of the more valuable currencies in rewards because of where the points can go. On its own it earns flexible points, but paired with a premium Capital One card you can pool them together and unlock 1 to 1 transfers to 7 airline and hotel partners: Air Canada Aeroplan, Turkish Miles & Smiles, Avianca LifeMiles, Flying Blue (Air France/KLM), Singapore Airlines, British Airways, and Wyndham Rewards. As an earner, its job is to rack up points cheaply that you move to a hub card before transferring. The sweet spots are usually premium-cabin flights and high-end hotel nights, where a single point can be worth well more than the 1 cent we value it at here.

If your business spends a lot and wants simple, uncapped 2% cash back, the Spark Cash Plus is a top choice, the fee can be waived through spending, and the welcome bonus is huge.
If you want transferable points, pair it with a Venture card to pool the rewards into miles, or choose a Venture business card directly. For pure high-volume cash back, this is excellent.
