Learn About Balance Transfer Options for Rewards Cards

Understanding Balance Transfers and How They Work

A balance transfer moves debt from one credit card to another card, usually one offering a lower interest rate. When you initiate a balance transfer, you're asking your new card issuer to pay off your existing balance from another card. The debt then moves to your new card, where you'll owe the balance instead.

The primary appeal of balance transfers relates to interest rates. A rewards card with a 0% introductory APR (annual percentage rate) on balance transfers can save significant money compared to a standard card charging 18-25% APR. For example, if you carry a $5,000 balance on a card with 22% APR, you'd pay approximately $1,100 in interest over a year if you made only minimum payments. Transferring that balance to a card offering 0% APR for 12 months could eliminate that interest charge entirely during the promotional period.

Balance transfers involve specific mechanics worth understanding. The process typically takes 3-7 business days, though some transfers complete within 24 hours. During this transfer period, you may owe interest on both cards if you continue carrying balances. Most balance transfer offers come with an introductory period ranging from 6 to 21 months, depending on the card.

A crucial element is the balance transfer fee. Nearly all rewards cards charge 3-5% of the transferred amount, though some cards may offer promotional periods without this fee. On a $5,000 transfer with a 3% fee, you'd pay $150 upfront. This fee typically gets added to your new balance on the transfer card.

Practical Takeaway: Before pursuing a balance transfer, calculate whether the interest savings during the promotional period exceed the transfer fee cost. Write down the transfer fee percentage, the promotional APR period length, and your current interest rate to determine potential savings.

Types of Balance Transfer Offers on Rewards Cards

Rewards cards market several distinct balance transfer structures, each with different advantages. Understanding these variations helps you identify which option aligns with your financial situation.

The most common structure offers 0% APR for a set period—typically 6 to 21 months—followed by a standard variable APR. Cards from major issuers often provide 12-15 months of 0% APR on balance transfers. Some premium rewards cards extend this to 18-21 months. The length of the promotional period significantly affects total savings. A six-month 0% period suits people paying down debt quickly, while an 18-month period works better for those needing longer to eliminate the transferred balance.

A second type combines 0% APR with reduced transfer fees during promotional windows. Certain cards waive the standard 3-5% transfer fee for the first 60-90 days after opening, then apply regular fees. This variation eliminates the upfront cost obstacle for borrowers timing their applications strategically.

Some cards offer tiered balance transfer benefits. These might include 0% APR for 12 months plus a flat transfer fee (like $25 regardless of amount), which benefits people transferring larger balances where the fixed fee represents less than a percentage-based fee.

A less common structure involves ongoing reduced rates rather than an introductory period. These cards might offer ongoing APR reductions—for example, 7.99% APR on transferred balances instead of the standard 22% APR. This structure lacks the urgency to pay down debt quickly since there's no expiration date on the lower rate.

Business rewards cards sometimes feature different balance transfer structures than consumer cards, occasionally with longer promotional periods or different fee arrangements targeting entrepreneurs and business owners.

Practical Takeaway: List the balance transfer offers from three cards you're considering. For each, note the promotional APR percentage, the promotional period length in months, and the transfer fee structure. This side-by-side comparison reveals which offer provides the most value for your specific debt amount and repayment timeline.

Calculating Your Potential Savings from a Balance Transfer

Determining whether a balance transfer makes financial sense requires calculating specific numbers. This process involves understanding your current interest costs and comparing them to potential savings through a transfer.

Start by calculating your current monthly interest charges. Take your existing credit card balance, multiply it by the monthly interest rate (your APR divided by 12), and you get the monthly interest cost. On a $7,000 balance with a 21% APR, you'd calculate: $7,000 × (0.21 ÷ 12) = $122.50 in monthly interest alone.

Next, determine what balance transfer fee you'd pay. If the card charges 3% and you're transferring $7,000, multiply $7,000 × 0.03 = $210 fee. Add this to your new balance, making it $7,210 that you'd owe on the new card.

Calculate your interest savings during the promotional period. If the new card offers 0% APR for 15 months, you'd save $122.50 per month in interest. Over 15 months, that's $1,837.50 in saved interest. Subtract the $210 transfer fee, and you net $1,627.50 in savings.

However, this calculation only works if you pay down the balance during the promotional period. If you don't pay anything and the promotional period ends, the remaining balance suddenly jumps to the card's standard APR—often 20-25%. Many people make the mistake of ignoring the balance after transferring it, then face shock when the introductory rate expires.

Consider also what happens if you miss a payment. Most card issuers will revoke your promotional rate and apply the standard APR if you miss a payment during the promotional period, even by one day. This makes on-time payments critical during the transfer period.

Use this comparison formula: (Monthly interest you currently pay × number of months in promotional period) − Balance transfer fee = Net savings. If this number is positive and substantial, a balance transfer warrants consideration.

Practical Takeaway: Use a calculator or spreadsheet to compute your exact savings. Plug in your current balance, current APR, the promotional APR percentage and length, and the transfer fee percentage. Calculate the interest you'd pay without transferring, then subtract the transfer fee and interest during the promotional period to find your net savings.

Rewards Benefits While Carrying Transferred Balances

A significant question many people ask is whether they continue earning rewards on a balance transfer card while paying down transferred debt. The answer depends on the card's specific rewards structure.

Most rewards cards continue earning cash back or points on new purchases made after a balance transfer, even while you're paying down the transferred balance. For example, if you transfer $5,000 to a card earning 1.5% cash back on all purchases, you continue earning 1.5% on new spending. This creates an opportunity to earn rewards while aggressively paying down debt.

However, using the card for new purchases while carrying a balance transfer presents financial risks. Credit card companies apply payments in specific ways. Most cards apply your payments to the lowest APR balance first. If you transfer a $5,000 balance at 0% APR and then charge $2,000 in new purchases at 20% APR, your payment goes toward the 0% balance first. This means the higher-rate purchases accumulate interest while you pay the zero-interest balance.

Some cards apply payments differently based on their terms. A few cards split your payment proportionally between different APR balances, or apply it to the highest APR first. Reading your card's specific terms reveals their payment allocation method.

A practical strategy involves transferring the balance, then using a different card for new purchases while you pay down the transferred balance. This avoids the confusion of multiple APR balances on one card. If you choose to make new purchases on the transfer card, make substantially larger payments than the minimum—enough to cover both the principal on the transferred balance and all new purchases.

Category-based rewards cards add another consideration. A card offering 3% cash back on groceries still earns 3% on grocery purchases you make after a balance transfer. Some people maximize this by using the balance transfer card for high-category spending while aggressive paying down the transferred balance with a second income source (bonus payments, tax refunds, or part-time income).
