What is a balance transfer?

A balance transfer moves debt from a high-APR credit card to a new card offering a 0% (or low) intro APR for a promotional period — typically 12, 18, or 21 months. Most cards charge a one-time transfer fee of 3%–5% of the amount transferred. The strategic goal is to pay down the balance during the intro period without accruing interest, then either pay off the card or transfer again before the post-intro APR kicks in.

How much can I save with a balance transfer?

Savings depend on three factors: the spread between your current APR and the intro APR, the length of the intro period, and the transfer fee. On an $8,000 balance at 22% APR, a typical 18-month 0% intro transfer with a 3% fee saves about $1,500 in interest compared to paying off the same balance on the original card. Larger balances and longer intro periods yield larger absolute savings.

What is a typical balance transfer fee?

Most balance transfer cards charge 3%–5% of the transferred amount, with $5–$10 minimums. Some cards occasionally offer promotional 0% fees for the first 60–90 days. The fee is typically added to your balance (or deducted from your credit limit). Always factor the fee into your break-even math: a 5% fee on $10,000 is $500, so you need to save at least $500 in interest during the intro period for the transfer to be worthwhile.

What happens after the intro period ends?

When the intro period ends, the remaining balance starts accruing interest at the card's post-intro APR (often 15%–25%). If you haven't paid off the full balance by then, the interest cost will resume. Some cards apply deferred interest: if even $1 remains at the end of the intro period, all the interest from the original purchase date may be added to your balance. Read your cardholder agreement carefully.

Can I transfer a balance between the same issuer's cards?

Most issuers prohibit balance transfers between their own products (e.g., you generally can't move a Chase balance to another Chase card). Balance transfers are designed to attract customers from competitors. The receiving card's issuer pays the originating issuer, and the bank wants new business, not internal reshuffling.

Does a balance transfer affect my credit score?

Balance transfers affect your credit in three ways: (1) the new card creates a hard inquiry (small, temporary drop of 5–10 points); (2) the new card's credit limit may lower your overall utilization ratio if you keep the old card open with a zero balance (helpful); (3) closing the old card after the transfer can increase utilization (harmful). Best practice: keep the old card open with a zero balance, and your score should recover within 3–6 months.

How do I choose the best balance transfer card?

Focus on three numbers: the intro APR (lower is better; 0% is ideal), the intro period length (longer gives you more runway; 18–21 months is typical), and the transfer fee (lower is better; aim for ≤3%). Other features like rewards, sign-up bonuses, and ongoing APR matter less if your goal is purely interest savings. Compare the total cost across the intro period: balance × fee rate + expected post-intro interest.

Should I do a balance transfer or take a personal loan?

A balance transfer makes sense when: (1) the intro APR is 0%, (2) the intro period is long enough to pay off most of the balance, (3) the transfer fee is ≤3%, and (4) you have the discipline to avoid new charges on either card. A personal consolidation loan makes more sense when: (1) the balance is large (over $15,000), (2) the intro period is too short, (3) the post-intro APR is high, or (4) you want a fixed payoff date. Compare the loan's APR, origination fee, and term against the transfer card's offer.

Balance Decline: Keep vs. Transfer

Key Insights

Your 18-month intro period is tight against the 29-month payoff timeline. You may carry a balance into the post-intro APR. Increase your monthly payment to ensure you finish before the cliff.

Transferring saves $2,596.88 — a modest 23.43% reduction. The savings are real but small. Consider whether the hassle of a new card is worth it for this amount.

Your post-intro APR of 18.00% is below your current rate — a useful safety net. Even if you don't fully clear the balance during the intro period, you'll still be paying less interest than you would on the current card.

Your transfer fee of 3.00% ($240.00) is typical for balance transfer cards. Factor it into the break-even math: you'll need to save at least this much in interest during the intro period.

Transferring pays off the balance 8 months sooner — a small speed-up.

How to Use This Calculator

1Enter your current credit card balance — the total amount you owe today.
2Set the APR on your current card. This is shown on your statement; typical rates range from 18%–28%.
3Adjust the transfer fee rate. Most cards charge 3%–5%; some offer 0% for an introductory period.
4Set the intro APR on the new card. 0% is the goal; anything below 5% is good.
5Choose the intro period length in months. 12, 15, 18, and 21 months are common offers.
6Set the post-intro APR — the rate that kicks in after the intro period ends.
7Enter the fixed monthly payment you can commit to. This must be the same for both scenarios.
8Compare the two scenarios: keep your current card vs. transfer to the new card. Watch the Total Savings, Months Saved, and the balance-decline chart.

Formula

How It's Calculated

The balance transfer calculator runs two parallel month-by-month simulations:

SCENARIO 1: Keep current card
  startingBalance = currentBalance
  rate = currentApr
  Each month:
    interest = balance × (rate ÷ 12)
    payment = min(monthlyPayment, balance + interest)
    principal = payment − interest
    balance = max(0, balance − principal)

SCENARIO 2: Transfer to new card
  startingBalance = currentBalance + (currentBalance × transferFeeRate)
  rate = (month <= introMonths) ? introApr : postIntroApr
  Same month-by-month accrual as scenario 1.

SAVINGS:
  savings = keepTotalPaid − transferTotalPaid
  payoffFasterMonths = keepMonths − transferMonths
  isWorthwhile = savings > 0

Example: $8,000 balance, 22% APR → 0% intro for 18 mo at 3% fee, $300/mo
  Keep-current: 37 months, $11,083 total, $3,083 interest
  Transfer:    31 months, $9,600 total, $1,360 interest + $240 fee
  Savings:     $1,483
  Payoff 6 months faster
  Net benefit: 13.4% reduction in total cost
