What Qualifies as Low Interest?
A good APR for a credit card is below 13%, as that is roughly the average regular purchase APR among credit card offers for people with excellent credit. By comparison, the average rate on accounts that accrued interest was 21.52% as of February 2026.
According to August 2025 data from the Federal Reserve, the average credit card interest rate is 21.39%. However, if the low end of the variable percentage is around 19 percent, we generally qualify it as a low-interest card.
Credit Score Requirements
You need solid credit to qualify for cards with genuinely low rates. Most cards require a credit score of 670-700 minimum. The higher your score, the lower the rate within any given card’s APR range.
Scoring works this way: a card advertising “13.74% to 18.00%” will give the 13.74% rate to someone with excellent credit (760+) and the 18.00% rate to someone with good credit (700-739). You won’t know your exact rate until after approval.
Two Paths to Low Interest
Option 1: Ongoing Low-Interest Rate Cards
These are cards that maintain consistently low interest rates throughout your cardholding, without an introductory period. The Titanium Rewards Visa® Signature Card from Andrews Federal Credit Union offers a low variable APR of 13.74% to 18.00% on purchases; 13.74% to 17.99% on balance transfers.
The catch: these cards almost always come from credit unions or regional financial institutions, not major national banks. Many cards that offer low interest rates come from credit unions, which require membership.
Credit Union Membership Options:
You need to be a member of First Tech Federal Credit Union to qualify for this card, but anyone can join at no added cost. Become a member through affiliation with select organizations or employers, a relationship with a current member, working in certain industries, or simply making a donation to the credit union.
Most credit unions offer APRs 4-8% below major bank cards for similar credit profiles. Membership often requires living in a geographic area or working in a specific industry, but many are open to anyone via a small donation or fee.
Specific cards worth considering:
- Andrews Federal Credit Union Titanium Rewards Visa: 13.74%-18.00% on purchases, requires membership to Navy/military-affiliated credit union
- Arkansas Federal Credit Union Low-Rate Classic: 0% introductory APR for 18 billing cycles applies to eligible balance transfers made to your Arkansas Federal Credit Union Low-Rate Classic credit card
Option 2: Balance Transfer Cards with 0% Introductory APR
Major banks offer cards with 0% APR for 12-21 months on balance transfers. This is an easier path since there’s no membership requirement, though you need good credit (690+).
0% intro APR on purchases for 21 billing cycles available on several cards from Chase, Citi, and American Express. The tradeoff: after the promotional period expires, the regular APR kicks in (typically 16.99%-27.99%), which is higher than ongoing low-interest cards.
Balance transfer cards charge a fee: typically 3-5% of the transferred amount. If you transfer $5,000, you’ll pay $150-250 upfront. Calculate whether this is worth the savings before proceeding.
The Math: When Balance Transfers Make Sense
If you carry a balance at 21% APR on $5,000:
- Monthly interest charge: approximately $88
- Over 12 months: $1,056 in interest
Transferring to a 0% card with a 3% fee ($150) means:
- You save $906 in year one
- Every payment goes to principal, not interest
This only works if you actually pay off the balance during the 0% period. Minimum payments won’t cover it. A $10,000 balance at $200/month minimum payment yields $3,600 paid over 18 months. You’re left with $6,400 when the promotional period expires.
Calculate your required monthly payment: (Balance + Transfer Fee) ÷ Promotional Months
For $5,000 balance + $150 fee over 21 months = $247/month required. If you can’t commit to that, don’t attempt the transfer.
Credit Union Cards with Permanent Low Rates
8.99% starting APR is available to qualified members — significantly below the 22%+ average bank card rate. These are navy credit unions and similar institutions offering rates that stay low permanently.
Eligibility varies:
- Navy Federal Credit Union: Military, veterans, DoD civilians, family members
- USAA: Military, veterans, and their families
- Andrews Federal Credit Union: Limited geographic area (Washington DC, Maryland, Virginia, New Jersey)
- First Tech Federal Credit Union: Tech industry employees, members
Many credit unions allow anyone to join with a small donation ($25-50) to a partner organization.
No Annual Fee Rule
All competitive low-interest cards charge zero annual fee. If a card quotes an annual fee, skip it—better options exist.
Balance Transfer Fee Comparison
- Standard: 3-5% of transferred amount
- Best option: 3% fee (look for Citi Diamond Preferred or similar)
- Worst option: 5% fee plus a minimum ($50+)
This is one of few cards out there that doesn’t charge a balance transfer fee – most charge between 3% and 5% per transfer. Cards without balance transfer fees are rare and typically military-affiliated.
Steps to Apply
- Check your credit score. Free through AnnualCreditReport.com or your bank’s app. You need minimum 670; 700+ for best options.
- Determine your goal. Are you consolidating existing debt (balance transfer card) or seeking ongoing low rates for future charges (credit union card)?
- For credit union cards: Search for credit unions matching your eligibility. Check their membership requirements and APR offerings.
- For balance transfer cards: Compare promotional periods (aim for 18+ months). Calculate whether you can pay off your balance within that window.
- Apply. Submit the application. Approval typically takes 1-7 business days.
- Complete balance transfer within 30-60 days of card opening to ensure eligibility for promotional rate.
- Set up automatic payments. Don’t make new purchases on the card—only use it for the balance transfer payoff.
Alternatives If You Don’t Qualify
If your credit is below 670:
For balances over $10,000 that will take 2+ years to pay off, a personal loan at 8-12% fixed APR through a credit union or LightStream/SoFi often beats credit card rates. The fixed term also creates a defined payoff date.
Personal loans have advantages over credit cards: fixed rates, fixed terms, and monthly payments that don’t change. The disadvantage: you pay interest throughout the entire term, unlike 0% balance transfer periods.
Why Credit Unions Offer Better Rates
Credit unions are member-owned cooperatives, not profit-driven corporations. They return surplus revenue to members through lower rates and fewer fees. That’s why their card rates consistently beat national banks by 4-8 percentage points.
The membership requirement seems like a barrier but typically requires only a donation ($25-50) to a partner organization. Most people can find a credit union they’re eligible to join.
Common Mistakes
Mistake 1: Using the balance transfer card for new purchases. New purchases accrue interest immediately at the regular APR. Only use it for the transferred balance.
Mistake 2: Not calculating required payments in advance. If you can’t afford the monthly payment needed to eliminate the balance during the 0% period, the strategy fails.
Mistake 3: Missing the transfer deadline. You typically have 30-60 days from approval to initiate the balance transfer. If you miss this window, you lose the promotional rate on your transfer—it will be subject to the regular APR.
Mistake 4: Opening multiple cards in short succession. Each application triggers a hard inquiry, which temporarily lowers your score. Space applications out by 3+ months if possible.
Mistake 5: Choosing based on rewards instead of interest rates. If you’re carrying a balance, focus on the lowest rate first. Rewards are irrelevant compared to interest savings.
Bottom Line
The lowest ongoing rates (8-12% APR) come through credit unions and require membership. Most people can join by making a small donation to an affiliated organization.
0% balance transfer cards from major banks are easier to access (no membership) but only work if you actually pay off the balance during the promotional period. Calculate your required monthly payment before applying.
Compare the entire APR range, not just the advertised low end. Know that your actual rate depends on your credit score. Don’t open multiple cards simultaneously—space applications out.
