5 things you need to know about the Merrick Bank Double Your Line® Mastercard®
1. Good opportunity to build credit
If you’re looking to build credit, the Merrick Bank Double Your Line® Mastercard® could help.
The Merrick Bank Double Your Line® Mastercard® reports to all three major credit bureaus. This gives you the opportunity to demonstrate a positive credit history by making on-time payments.
When possible, you might be able to further boost your credit by paying off your balance in full each month before your statement balance closes. This could help lower your credit card utilization, which is another key component that goes into determining your credit scores.
2. Not much spending power
When it comes to spending, the Merrick Bank Double Your Line® Mastercard® doesn’t give you much room.
Your initial credit limit will be somewhere between $750 and $1,500, though you may see different terms if you apply through Credit Karma.
But after you make your first seven payments on time (paying at least the minimum amount due each month), the Merrick Bank Double Your Line® Mastercard® will automatically double your credit line with a credit limit increase, which is another way to lower your credit utilization ratio and potentially boost your scores.
Because your credit usage is another key factor in building credit, it’s important to use no more than 30% of your available credit each month.
That means until Merrick raises your credit line, it’s a good idea to keep an eye on your balance.
3. Watch for interest charges
If you can, pay off your balance in full each month. Not only will this help your credit, but it could also save you money on interest charges.
The Merrick Bank Double Your Line® Mastercard® charges a variable purchase APR of 29.7% (you might see a different rate if you apply through Credit Karma or directly through Merrick). With an APR this high, interest charges could add up pretty quickly if you carry a balance from month to month.
4. No collateral required
The Merrick Bank Double Your Line® Mastercard® is an unsecured credit card. By definition, you won’t be required to pay a security deposit like you would with a secured credit card.
Some secured credit card security deposits are refundable. But this card’s lack of deposit could make it more attainable for people who don’t have the cash on hand.
5. Charges fees upfront
For a card that has no security deposit, the Merrick Bank Double Your Line® Mastercard® has a lot of upfront costs. There’s a one-time account set-up fee of up to $75. That’s in addition to the card’s $0 annual fee, though you might see different annual fees on Credit Karma.
You’ll have to pay close attention to the confusing fee structure. Merrick lists this fee as part of a range, so it’s unclear exactly how much you’ll be charged. And unlike a security deposit, this fee isn’t refundable.
It’s important to note that Merrick may subtract the cost of the set-up fee from your total credit line before you even begin using the card. For example, let’s say you’re approved for a credit limit of $550. If Merrick charges you a set-up fee of $75, your total available credit limit will only be $475.
What else you need to know
There are a few more things you should keep in mind before you apply for the Merrick Bank Double Your Line® Mastercard®.
- By invitation only — The Merrick Bank Double Your Line® Mastercard® isn’t open to everyone — you must be invited to apply. This could either come in the form of an offer through your Credit Karma account or an invitation you receive by mail directly from Merrick Bank.
- Make sure you pay on time — The Merrick Bank Double Your Line® Mastercard® charges a hefty late fee of up to $40.
- No rewards — Some cards give you a little something back while you build credit, which can be a good motivator to continue making progress. But the Merrick Bank Double Your Line® Mastercard® isn’t one of them.
Who this card is good for
The Merrick Bank Double Your Line® Mastercard® is geared toward people who are looking to build credit for the first time, as well as those with poor credit who want to rebuild their credit.
This card could be a good fit if you can’t afford a security deposit upfront. The problem is, with the one-time set-up fee, you’ll still have to fork over cash that you won’t get back down the road.
Not sure this is the card for you? Consider this alternative.

Credit Karma owes me $50
— Credit Karma Member
I applied for this card because of the "Karma Guarantee" which states "You'll be approved or CK will pay you $50." I applied. I was denied. CK owes me $50 BUT has ghosted. When I log in now the same card offer says "Caution: your chance of approval is poor." Guess you should have dug deeper before promising me $50. NOW PAY UP OR I'LL REPORT -YOU- TO THE CREDIT BUREAUS!
