Capital One Platinum Secured Review
Lower deposit requirements, Mastercard acceptance, and automatic credit line increases. A solid alternative.
⚡ Quick Verdict
Best for: People who can't afford Discover's $200 minimum, need wider Mastercard acceptance, or want automatic credit limit increases. No rewards, but lower barrier to entry.
How It Works
The Capital One Platinum Secured is unique because your required deposit depends on your creditworthiness:
- Best case: $49-99 deposit for $200 credit limit
- Typical case: $200 deposit for $200 limit
- You can add more: Up to $1,000 total deposit
This flexibility is Capital One's main advantage. Some people get a $200 limit for only $49 — a much lower barrier than competitors requiring the full deposit amount.
Key Features
- No annual fee
- Mastercard network — Accepted almost everywhere worldwide
- Automatic credit line increases — After 6 months of on-time payments
- Reports to all 3 bureaus
- CreditWise access — Free VantageScore monitoring
- $0 fraud liability
Automatic Credit Line Increases
Capital One may automatically increase your credit limit after 6+ months of responsible use — without requiring additional deposit. This is a significant benefit:
- Increases come with no additional deposit needed
- Lower utilization ratio from higher limit
- Signal that you're on track for graduation
💡 Graduation Path
Capital One reviews accounts periodically. After demonstrating responsible use (typically 6-12 months), you may be upgraded to an unsecured card and receive your deposit back. This isn't guaranteed on a specific timeline like Discover's 7-month review.

Who Should Get This Card?
✓ Ideal For
- • Can't afford $200 deposit upfront
- • Need Mastercard acceptance (international travel, Costco, etc.)
- • Want automatic credit line increases
- • Don't care about rewards
✗ Get Discover Instead If
- • You can afford the $200 deposit
- • You want cash back rewards
- • You prefer a guaranteed graduation timeline
How to Apply
- Pre-qualify first: capitalone.com/credit-cards/prequalify (soft pull)
- See your deposit requirement: Pre-qual shows what deposit you'd need
- Apply if terms are acceptable
- Fund your deposit: Via bank transfer
- Receive and activate card
Tips for Success
- Use it monthly: Regular activity helps trigger limit increases
- Always pay on time: This is non-negotiable for building credit
- Keep utilization under 30%: On a $200 limit, that's $60 max
- Check for upgrade offers: Log in regularly to see if you qualify
- Don't close after upgrading: Keep it for the credit history
The Bottom Line
The Capital One Platinum Secured is a solid second choice to the Discover it Secured:
- Best feature: Potentially low deposit ($49-99)
- Biggest drawback: No rewards
- Best for: Budget-constrained builders who need Mastercard
If you can manage $200, the Discover it Secured is better due to rewards. But if that deposit is a barrier, Capital One gets you building credit for less upfront.
