Capital One Platinum Secured Credit Card Review: Start building your credit with security deposits as low as $49

The Capital One Platinum Secured Credit Card provides an accessible option for improving your credit history with required deposits starting as low as $49, depending on the conditions of your application.

Below, CNBC Select breaks down the rewards, benefits and fees associated with the Capital One Secured Card to help you decide if it's the right card for you.

Traditionally, secured credit cards are for people who have no credit history or need to repair their credit score. The limits for secured credit cards are determined by the amount of money a cardholder puts down as a deposit. This is done to protect a lending institution when the consumer it's lending to has little history to prove they are a reliable borrower. The deposit is fully refundable given your balance is paid off when you close the account. Typically, secured credit card deposits range from $200 to $2,500.

The Capital One Secured card comes with a credit limit of $200, with options to increase once you prove to be a borrower who pays bills on time and spends within your means. But unlike other cards that require you to deposit the exact amount of your credit limit, with a Capital One Platinum Secured Credit Card there is some flexibility on how much a consumer has to put down in order to qualify for a $200 credit limit. According to Capital One's website, your deposit amount is determined by your application and could be either $49, $99 or $200 — and any of these will qualify you for an initial $200 credit limit.

With the Capital One Platinum Secured Credit Card, you can automatically be considered for a higher credit line in as little as 6 months with no additional deposit needed. For this reason, plus the possibility of only having to deposit $49, the Capital One Secured card is one of CNBC Select's picks for best credit cards for building credit.

Unlike a prepaid or debit card, using a secured credit card allows you to improve your credit score. Your on-time payments will be reported to the three main credit bureaus — Equifax, Experian and TransUnion —just like with a traditional credit card. Your good behavior will show up on your credit report and help you become a stronger applicant for better credit cards with more exciting rewards.

One of the most important factors in achieving a good credit score is making your payments on time. The Capital One Secured card makes it easy to do by giving you control over when your payments are due.

For example, if you get paid on the 15th of every month, you can set your due date to the 16th so that you can prepare to have the funds available.

There is also an option to set up personalized email and text reminders that alert you of upcoming payments.

Like all Capital One cards, the Capital One Platinum Secured Credit Card has no foreign transaction fees and there is also no annual fee.

The variable APR for the Capital One Platinum Secured Card is 29.99% on purchases and balance transfers, making it important for you to pay off your balance in full each month.

The Capital One Platinum Secured Credit Card makes building better credit accessible, but you can't be in a rush. While you can apply for this card without any credit history, there is no clear timeline for when consumers will become eligible for an unsecured credit card.

There are no rewards or benefits that come with the Capital One Platinum Secured card, whereas other options, like the Discover it® Secured Credit Card, deliver value that's comparable to popular cash back rewards cards. With the Discover it® Secured Credit Card, you can earn 2% cash back at gas stations and restaurants on up to $1,000 in combined purchases each quarter, then 1%.

Cardholders also earn unlimited 1% cash back on all other purchases automatically. There's also a clear timeline for when you can upgrade to an unsecured card: Starting at seven months from account opening, Discover will automatically review your credit card account to see if they can transition you to an unsecured line of credit and return your deposit.

But if you don't have $200 for a security deposit, the Capital One Platinum Secured Credit Card is one of the best secured credit cards because you can potentially qualify for a $200 limit with only a $49 deposit.

To determine which secured cards offer the best value for a range of consumers, CNBC Select analyzed popular secured credit cards offered by the biggest banks, financial companies and credit unions that allow anyone to join.

We compared each card on a range of features, including: annual fee, minimum security deposit, credit limit, rewards program, introductory and standard APR, welcome bonuses and foreign transaction fees, as well as factors such as required credit score and customer reviews when available. We also took into account how easy it is to upgrade the card from secured to unsecured and how quickly you can get your security deposit back.

Because it's unusual for secured credit cards to have robust rewards programs, we did not analyze how many rewards points you can earn in the first year. For cardholders who are looking to rebuild credit, it's more important to practice good credit card habits — spending within your means, paying your balance on time and in full — than try to optimize your points balance.
