You can apply for the Capital One Platinum Secured Credit Card with a minimum refundable deposit of $49, but that is one of three possible minimums and Capital One decides which deposit tier, if any, you are offered. The tiers are $49, $99, or $200. Capital One says an initial credit line of at least $200 is available once the required deposit is made, and its product page says an additional deposit can raise the initial line up to $1,000 under the conditions stated there. Treat “as low as $49” as the lowest possible deposit, not as an offer every applicant receives.
What the deposit does and does not do
A secured card requires a refundable deposit before the account opens, and that deposit becomes your credit line’s collateral. Capital One’s help center describes it this way:

“A secured card is a type of credit card account that requires a refundable security deposit to open, but works the same as other credit cards when you make a purchase.”

The deposit is not a fee, and it is not a payment toward your purchases. Your monthly bill is still due on its normal schedule, and you must make at least the minimum payment each cycle. The deposit sits behind the account as protection for the issuer.

Credit limit: what to expect from each deposit tier
The credit limit you receive depends on the deposit you are required to make, and the figures below are the minimums Capital One publishes for the offer checked on October 7, 2026.
- $49 minimum refundable deposit. Available only on some offers and to some applicants, as set by Capital One at approval.
- $99 minimum refundable deposit. A middle tier, also assigned at Capital One’s discretion.
- $200 minimum refundable deposit. The highest of the three published minimums.
- Initial credit line of at least $200. Capital One states this applies after the required deposit is made. The page does not tie a specific line amount to a specific tier, so the line you receive is whatever your approval materials show.
- Possible increase to as much as $1,000. The product page says an additional deposit may raise the initial line up to $1,000, subject to the conditions the issuer states on that page.
How to fund the deposit after approval
An approval is not finished until the deposit is received. Follow these steps once you are approved:

- Read your approval materials first. The exact funding instructions and the deposit amount you were assigned appear there, and those materials govern if they differ from general guidance.
- Note the deadline. Capital One says the required minimum deposit is due within 35 days after approval.
- Fund online through the method Capital One describes in its help material. The help center says deposits can be made in installments of at least $20 each, so you do not have to send the full amount at once.
- Track the deposit until the account shows it as received. Keep your own record of each installment in case you need to confirm what was paid and when.
How you get the deposit back
Capital One’s help material describes two routes for the deposit, and they work differently.
Free tools Windows power users keep installed
One-click scans. No signup required.
- Account upgrade. When the account upgrades and no longer requires collateral, the deposit is returned to you as a statement credit.
- Account closure. If the account closes, the deposit funds are applied to any remaining balance. Any excess is refunded according to the process described in the help center.
Because the deposit is applied to a balance on closure, paying the account down before you close it can change how much of the deposit comes back to you.

Does a Capital One secured card build credit?
Capital One says it reports account status to all three major credit bureaus on a regular basis. A secured card can help build or rebuild a credit history when it is used responsibly, because on-time payments and low balances are the activity that bureaus record. That is a possibility, not a promise. Capital One does not guarantee a score increase, a particular score, or approval for other credit products. The result depends on your full credit file and how you use the account.
The path to an unsecured card
Capital One periodically reviews secured cardholders for eligibility to upgrade to an unsecured card. You cannot request the upgrade yourself. If your account becomes eligible, Capital One will notify you. There is no published timetable for these reviews, so you should not plan around a particular date. The upgrade is what triggers the deposit return described above.

Fees, APR and what the page does not show
| Term | What the issuer page checked on October 7, 2026 states |
|---|---|
| Annual fee | $0 |
| Purchase APR | 28.99% variable |
| Foreign transaction fee | None listed on the page |
| Replacement card fee | None listed on the page |
| Authorized-user fee | None listed on the page |
| Rewards | Not established on the page reviewed |
The 28.99% rate is a variable APR shown on the issuer page at the time of checking. Rates change, and your own offer disclosures are what apply to your account, so compare the figure in your approval materials with the one above. If you pay your statement balance in full each month, the stated terms mean you avoid purchase interest. If you carry a balance, interest accrues on it.
Recommended Free Tools
The fee list above is not a complete schedule. The page names only the exclusions shown in the table, and it does not list every possible charge. Before you rely on the absence of any other fee, read the full cardholder agreement linked in your application flow and confirm that it matches the offer you were shown.
Best Value
- ONE CARD PROTECTS YOUR WHOLE WALLET: Drop a single KF-Premium card into your wallet, purse, or card holder and every card sitting near it is shielded from contactless RFID and NFC scans, so you do not need a separate sleeve on each card. This 2-pack covers a second wallet, a passport holder, or a family member.
- ULTRA THIN AT 0.9MM, BARELY THERE: Each blocking card is only 0.9mm thick, about as slim as one of your bank cards, so it slides into any wallet slot without the bulk of foil sleeves or switching to a new wallet. Slim enough that you forget it is working.
- STOPS FRAUD BEFORE IT STARTS: The armoured shield design sends out an interfering counter-signal that blocks unauthorized RFID and NFC readers from skimming your debit cards, credit cards, and IDs. It guards against contactless payment fraud, identity theft, and digital pickpocketing in crowds, on transit, and while you travel.
- WORKS THE MOMENT IT IS IN YOUR WALLET: No batteries, no charging, no app, and nothing to switch on. Protection is automatic and continuous for the life of the card, and the durable, high-quality build holds up to daily wear in a back pocket or bag.
- A PRACTICAL GIFT THEY WILL ACTUALLY USE: The sleek black finish gives it a premium look that suits travelers, students, parents, and anyone who carries contactless cards. Boxed as a 2-pack, it works for birthdays, holidays, or a stocking filler that quietly protects the people you care about.
How to compare it with other secured cards
If you are weighing this card against another secured option, compare the same details for each one:
- Annual fee
- Current variable purchase APR, checked from the live offer
- Minimum deposit, and whether that deposit determines your initial credit line
- Whether the issuer reports to all three major credit bureaus
- How the deposit is funded, how long you have to fund it, and how it is returned
- Whether the upgrade to an unsecured card is discretionary and how the issuer reviews it
- Any rewards, confirmed in the agreement rather than assumed
Who this card suits
- People who can set aside a refundable deposit and want a card that reports to all three bureaus.
- People who will pay the full statement balance most months, which avoids purchase interest under the stated terms.
- People who want a $0 annual fee and are willing to wait for an upgrade that Capital One decides on.
It is a weaker fit if you need a large credit line immediately, want rewards, or cannot spare the deposit. In those cases, compare the deposit and line terms with other secured cards before you apply.
