Credit card debt is expensive — typically 20-30% APR means it doubles every 3-4 years if unpaid. Here’s how to clear it efficiently and get back on track.
Understanding Your Debt First: Know What You Owe Card Balance APR Min Payment Card 1 £ % £ Card 2 £ % £ Card 3 £ % £ Total £ — £
Calculate True Cost Balance APR Monthly Interest £2,000 22% ~£37 £5,000 25% ~£104 £10,000 22% ~£183
This is money just disappearing — going to interest, not reducing your debt.
Strategy 1: Avalanche Method (Mathematically Best) How It Works Detail Pay minimum on all cards Keeps accounts current Put ALL extra money on highest APR card Kills the most expensive debt first Once that’s clear, target next highest Continue until debt-free
Why It’s Best Benefit Detail Saves most money Eliminates most expensive interest first Fastest payoff (mathematically) Less total interest paid Logical Financially optimal
Example Card Balance APR Order to Pay Card A £3,000 18% Third Card B £1,500 29% First Card C £2,500 22% Second
Even though Card A has the highest balance, Card B’s higher interest rate makes it more expensive.
Strategy 2: Snowball Method (Psychologically Powerful) How It Works Detail Pay minimum on all cards Keeps accounts current Put extra money on smallest balance Quick win Once clear, add that payment to next smallest Payments “snowball” as debts clear Continue until debt-free Builds momentum
Why It Works Benefit Detail Quick wins Clearing cards faster feels good Motivation Seeing progress maintains momentum Fewer accounts to track Simplifies life
Example Card Balance APR Order to Pay Card A £3,000 18% Third Card B £1,500 29% First (smallest)Card C £2,500 22% Second
Clear £1,500 first for the quick win and motivation boost.
Avalanche vs Snowball Method Saves More Money Better Motivation Avalanche ✓ Snowball ✓
Choose based on your personality. Snowball gets more people to actually finish.
Strategy 3: Balance Transfer How It Works Detail Transfer debt to 0% card Stop paying interest Pay off during 0% period All payment goes to principal Clear before 0% ends Or transfer again
When to Use Situation Balance Transfer Suitable? Good enough credit to get 0% card Yes Can clear in 0% period Yes Discipline to not add more debt Yes Poor credit May not get a good enough offer

Direct Savings to Debt Found Impact £50/month extra £600/year extra to debt £100/month extra £1,200/year extra to debt £200/month extra £2,400/year extra to debt
Every extra pound goes directly to reducing your debt when added to minimum payments.
Payment Guidelines Minimum Payment Only (Avoid This) Problem Detail Takes forever Decades to clear Costs a fortune Multiple times the original debt Only keeps account current Doesn’t meaningfully reduce debt
Ideal Payment Level Guideline Effect Pay 10%+ of balance monthly Meaningful progress Pay as much as possible Fastest clearance At least 3× minimum Better than minimum
Should You Use Savings? The Maths Scenario Numbers Savings earning 4% interest Card charging 22% interest Net effect of keeping savings Losing 18%
Recommendation Action When Keep small emergency fund £500-1,000 so unexpected costs don’t create more debt Use rest to clear card debt Almost always the right call Then rebuild savings Once expensive debt is clear
What About Debt Consolidation Loans? Feature Detail What it is Single loan to pay off multiple debts Rate Often lower than credit cards (6-15%) Fixed payment Easier to budget Fixed term Clear deadline
When It Makes Sense Situation Consideration Multiple cards at high rates Consolidation can help Can’t get 0% balance transfer Loan may be next best Need structure Fixed payments help some people Lower total interest Check the maths
Warning: Don’t take a consolidation loan then run up new card debt.
When to Get Help Warning Signs Sign What It Might Mean Only paying minimums Stuck in debt spiral Borrowing to pay other debts Getting worse Missing payments Serious problem Constant worry/stress Affecting life Using one card to pay another Dangerous spiral
Where to Get Free Help Organisation Detail StepChange Free debt advice charity Citizens Advice Free, confidential advice National Debtline Free phone advice PayPlan Free debt management

Staying Out of Debt Once Cleared Action Why Keep one card for emergencies/protection Don’t need multiple Pay in full every month Never pay interest again Build emergency fund So unexpected costs don’t need cards Budget monthly Know where money goes
Break the Cycle Habit Benefit Wait 24 hours before big purchases Avoid impulse Track all spending Awareness reduces waste Distinguish wants vs needs Prioritise necessities Use cash for problem categories Physical limits stop overspending
