Balance transfers are one of the most effective ways to clear credit card debt — moving existing debt to a 0% interest card gives you breathing room to pay it off without interest eating into your payments.
How Balance Transfers Work
Step
What Happens
1
You apply for a balance transfer credit card
2
You’re approved with a credit limit
3
You request a transfer of your old debt
4
New card company pays your old card
5
Balance now sits on new card at 0%
6
You make monthly payments to clear the debt
7
0% period ends — any remaining balance charged full APR
Key Terms

Don’t
Action
Why

Spend on the new card
Probably not at 0%
Transfer to same bank
Not allowed
Ignore the end date
Revert rate is expensive
Only pay minimums
Won’t clear debt in time
Spending on Balance Transfer Cards
Type of Transaction
Likely Interest Rate
Transferred balance
0% for promotional period
New purchases
Usually full APR (20-30%)
Cash withdrawals
Full APR + fees, day 1
Recommendation: Don’t spend on balance transfer cards. Use a different card for purchases.
Payment Allocation
How Payments Are Allocated
Rule
Minimum payment
Goes to lowest interest debt first
Payments over minimum
Go to highest interest debt first
So if you do spend on the card (not recommended), extra payments will clear the purchase first — but minimum goes to the 0% debt, leaving expensive debt growing.
When 0% Period Ends
Option 1: Debt Cleared
Scenario
Action
Debt paid off
Well done — nothing more to do
Keep card open
Helps credit score (account age)
Don’t need to use it
Occasional small spend keeps it active
Option 2: Debt Remaining
Scenario
Action
Small amount left
Try to clear it immediately
Significant amount
Consider another balance transfer
Cannot get new 0%
Focus intensively on clearing
Repeated Balance Transfers
Consideration
Detail
Can you keep transferring?
Sometimes, but each needs new application
Credit score impact
Multiple applications/cards affect score
Lender view
“Rate tarting” may lead to rejections
Is it sustainable?
Should be used to clear debt, not defer it
Best approach: Use balance transfer to clear debt, not to continually avoid it.

Action
Detail
Apply for new 0% card
Before current one ends
Transfer remaining balance
To new 0% card
