How long do 0% APR offers last?

Most 0% APR introductory offers last 12-21 months depending on the card. Balance transfer cards tend to have longer 0% periods (15-21 months) than purchase cards (12-18 months). After the intro period, the regular APR (typically 18-29%) kicks in.

Do 0% APR cards affect your credit score?

Opening a new card causes a small, temporary score dip from the hard inquiry. However, the increased available credit can lower your utilization ratio and improve your score. Using a 0% card to pay down debt faster typically results in a net positive impact on your credit.

What happens when the 0% APR period ends?

Any remaining balance starts accruing interest at the card's regular APR, typically 18-29%. Unlike deferred interest plans (common at stores), 0% APR cards don't charge back-interest on the original balance. You only pay interest on what's left after the intro period ends.

Balance Transfer Fee Math

Before transferring, make sure the interest savings exceed the balance transfer fee:

Balance	Transfer Fee (3%)	Transfer Fee (5%)	Break-Even at 22% APR
$2,000	$60	$100	2 months
$5,000	$150	$250	2 months
$10,000	$300	$500	2 months
$15,000	$450	$750	2 months
$20,000	$600	$1,000	2 months

At typical credit card rates (20-25%), the balance transfer fee pays for itself in about 2 months of avoided interest. Any 0% period longer than that is pure savings.

How to Use a 0% APR Card Strategically

For Balance Transfers

Step	Action	Tip
1	Apply for card with longest 0% period	Don’t apply for multiple cards at once
2	Transfer balance within 60 days of opening	Most cards require transfer in first 60 days
3	Calculate monthly payment to pay off in full	Divide balance by 0% months
4	Set up autopay for that amount	Don’t rely on minimums
5	Don’t make new purchases on the card	New purchases may not get 0% APR
6	Don’t close the old card	Keep it open for credit utilization

For Large Purchases

Step	Action	Tip
1	Apply for card with 0% on purchases	Some cards offer 0% on purchases + balance transfers
2	Make the purchase early in the billing cycle	Maximizes your 0% window
3	Divide total by months remaining in intro period	Set up equal monthly payments
4	Pay off completely before intro period ends	Mark the end date on your calendar
5	Avoid minimum-payment trap	Minimums won’t clear the balance in time

Common Mistakes to Avoid

Mistake	Why It’s Costly	How to Avoid
Only paying minimums during 0% period	Won’t pay off in time; interest hits remaining balance	Calculate and pay the full payoff amount monthly
Missing a payment	Some cards cancel 0% APR if you miss a payment	Set up autopay immediately
Making new purchases on a balance transfer card	Payments may apply to the transfer first, not new charges	Use a separate card for daily spending
Not knowing when 0% ends	Surprise interest charges	Set calendar reminder for 1 month before
Applying for too many cards	Multiple hard inquiries hurt your score	Apply for one card that fits best
Transferring between the same bank’s cards	Most banks don’t allow transfers between their own cards	Transfer to a different bank

0% APR vs. Deferred Interest (Store Cards)

Feature	0% APR (Credit Card)	Deferred Interest (Store Card)
Interest during promo period	None	Accruing silently
What happens if not paid in full	Interest on remaining balance going forward	All back-interest charged on original balance
Typical promo period	12-21 months	6-24 months
Danger level	Moderate	High
Example: $3,000 purchase, $500 remaining	Pay interest on $500 from that point	Charged interest on original $3,000 for entire period

Deferred interest is far more dangerous than true 0% APR. Always read the terms to know which you’re getting—store financing cards (furniture, electronics) typically use deferred interest.

After the 0% Period Ends

Remaining Balance	Regular APR (22%)	Monthly Interest Charge	Action to Take
$0	N/A	$0	Keep card for credit utilization
$500	22%	$9	Pay off immediately
$2,000	22%	$37	Consider another balance transfer
$5,000	22%	$92	Balance transfer or personal loan
$10,000+	22%	$183+	Personal loan likely better

If you can’t pay off the full balance, apply for a new 0% balance transfer card before your current offer ends to extend the interest-free period. This is sometimes called “surfing” balance transfers.
