How Do 0% Interest Credit Cards Work?

A 0% interest credit card gives you a period (usually 3–24 months) where you pay no interest on:

  • Purchases (new spending)
  • Balance transfers (moving debt from another card)

After the 0% period ends, the card's standard APR (interest rate) applies.

Two Main Types of 0% Cards:

  1. 0% Purchase Cards – No interest on new spending for a set time.
  2. 0% Balance Transfer Cards – No interest on moved debts for a set time (usually with a small transfer fee).

How to Choose the Best 0% Credit Card

1. Check the 0% Period Length

Longer = more time to pay off debt interest-free.

2. Look at Fees

Balance transfer cards usually charge 2–3% of the amount moved.

Some purchase cards have no fees.

3. Check Your Credit Score

The best 0% cards require good to excellent credit.

Use free checkers like:

4. Plan Repayments

Divide your debt by the 0% months to know the minimum monthly payment.

Example: £1,200 debt on a 12-month 0% card = £100/month.

5. Avoid New Spending on Balance Transfer Cards

New purchases may not be at 0% and could accrue interest.

How to Improve Your Chances of Approval

Banks prefer borrowers with good credit history. To boost approval chances:

  • Check your credit report for errors (Equifax, TransUnion)
  • Pay bills on time (late payments hurt your score)
  • Reduce existing debt before applying
  • Avoid multiple applications in a short time

Risks of 0% Credit Cards

⚠ High APR after 0% ends – If you don't clear the debt, interest jumps to 20–30%.

⚠ Missed payments can cancel 0% – Always pay at least the minimum.

⚠ Balance transfer fees – Usually 2–3% of the amount moved.
