Key takeaway
Assume your current card charges 24% APR and the transfer card charges a 3% fee with a 0% intro period. Transferring $10,000 to a 21-month promo requires $490/month to clear and saves $2,676 net versus making those same payments at 24%. Transferring $3,000 to a 12-month promo requires $258/month and saves $360 net. Bigger balances and longer promos mean bigger savings — but only if the balance hits zero before the promo expires.
Is a balance transfer worth it for you?
The answer depends on your balance, APR, transfer fee, promotional period, and monthly payment. Run your numbers with Figmetric’s free Balance Transfer Analyzer.
Run your numbers →The break-even table: payment needed and net savings
Each cell shows the monthly payment required to clear the transfer (balance + 3% fee ÷ promo months) and the net savings versus making that same monthly payment at 24% APR instead. Fee is already subtracted from the savings.
| Balance | 12-mo promo | 15-mo promo | 18-mo promo | 21-mo promo |
|---|---|---|---|---|
| $3,000 | $258/mo · saves $360 | $206/mo · saves $492 | $172/mo · saves $638 | $147/mo · saves $803 |
| $5,000 | $429/mo · saves $600 | $343/mo · saves $820 | $286/mo · saves $1,064 | $245/mo · saves $1,338 |
| $7,000 | $601/mo · saves $840 | $481/mo · saves $1,148 | $401/mo · saves $1,489 | $343/mo · saves $1,873 |
| $10,000 | $858/mo · saves $1,200 | $687/mo · saves $1,639 | $572/mo · saves $2,128 | $490/mo · saves $2,676 |
Worked example: $7,000 on an 18-month promo
Transfer $7,000 with a 3% fee: the new balance is $7,210, and clearing it in 18 months takes $401/month. If you instead paid $401/month toward the $7,000 at 24% APR, you would pay $1,699 in interest over those 18 months. The $210 fee replaces $1,699 of interest — net savings of $1,489. The fee is a one-time 3%; the interest it replaces compounds every single month. That asymmetry is the entire argument for balance transfers.

Calculate your savings →When a balance transfer FAILS
The transfer only wins if the balance reaches zero inside the promo window. Run the failure case: transfer $10,000 ($10,300 with the fee) to an 18-month 0% promo, but pay only $200/month. After 18 months you have paid $3,600 — and $6,700 is still unpaid when the promo expires. That $6,700 immediately starts compounding at the card's regular rate (often 24%+), and the $300 fee is already sunk. You paid for a head start and then gave most of it back.
Three more ways transfers fail:
- New spending on either card. Purchases on the transfer card usually accrue interest immediately (no grace period while a promo balance sits there), and running the old card back up leaves you with two balances.
- A late payment. Many issuers cancel the 0% promo after a single late payment, reverting the whole remaining balance to the penalty rate.
- Ignoring the fee in the plan. The payment that clears the promo is (balance + fee) ÷ months, not balance ÷ months. Forgetting the fee leaves a small balance to revert at the full rate.
Transfer vs. just paying more
A balance transfer is not the only way to beat 24% APR — a bigger fixed payment on the existing card also works, as the $20K/$30K payoff tables show. The transfer's edge is that every dollar of your payment attacks principal during the promo, which matters most when your payment is small relative to the balance. If you can already afford a payment that clears the debt in under two years, compare both paths in the analyzer below; sometimes the fee is not worth it. For juggling several promo cards at once, see juggling multiple 0% cards.
Bottom line
A 3% balance transfer fee is cheap compared to 24% APR — if you divide (balance + fee) by the promo months, autopay exactly that amount, make zero new charges, and never pay late. Fail any of those and the transfer becomes an expensive way to delay the inevitable. Do the division before you apply, not after.

Frequently asked questions
Is a balance transfer worth the 3% fee?
Usually yes, if you clear the balance within the 0% promo. A 3% fee on $7,000 is $210, but the same payments at 24% APR would cost $1,699 in interest over 18 months — $1,489 net saved. The fee is one-time; the interest it replaces compounds monthly. Longer promos and larger balances favor the transfer.
What happens if I don't pay off a balance transfer in time?
The unpaid remainder reverts to the card's regular APR — often 24% or more. Transfer $10,000 ($10,300 with fee) to an 18-month promo but pay only $200/month, and $6,700 is still unpaid at expiry, compounding at the full rate with the $300 fee already sunk.
How much do I need to pay monthly to clear a balance transfer?
Divide (balance + fee) by the promo months. $10,000 with a 3% fee is $10,300 total: $858/month for 12 months, $687 for 15, $572 for 18, $490 for 21. Autopay that exact amount from day one.
Do balance transfers hurt your credit score?
The new account causes a small temporary dip (hard inquiry, lower average account age), but the new credit limit usually lowers your utilization ratio, which helps. Paying the balance down during the 0% period helps more. The real risk is running the old card back up and ending with two balances.
Is there a balance transfer calculator?
Yes — Figmetric's free balance transfer analyzer compares the fee against the interest you would pay at your current APR, so you can see whether the transfer wins.
When is a balance transfer NOT worth it?
When you cannot clear the balance inside the promo window — the $210 fee on $7,000 only saves money if the 18 months at 0% actually retire the debt. Run the payoff date before you apply.
