Snowball vs. Avalanche Method
❄️ Debt Snowball
Pay off the smallest balance first, regardless of interest rate. When that card is paid off, roll that payment to the next smallest balance.
Pros:
- Quick wins boost motivation
- Psychological momentum
- Easier to stick with long-term
Cons:
- May pay more total interest
- Not mathematically optimal
🏔️ Debt Avalanche
Pay off the highest APR first. This minimizes total interest paid and is mathematically optimal.
Pros:
- Saves the most money
- Mathematically optimal
- Faster overall payoff
Cons:
- First payoff may take longer
- Requires more discipline
Bottom line: Avalanche saves more money, but Snowball can be more motivating. The best method is the one you'll actually stick with. Both are vastly better than minimum payments only.
The Minimum Payment Trap
Credit card companies set minimum payments intentionally low — typically 1-3% of your balance or $25, whichever is greater. This keeps you in debt longer and maximizes their interest income.
Example: $5,000 balance at 22% APR
- • Minimum payment (~2%): $100/month
- • Time to pay off: 9+ years
- • Total interest paid: $4,311
- • Total paid: $9,311 (nearly double!)
Same debt with $300/month payment
- • Fixed payment: $300/month
- • Time to pay off: 20 months
- • Total interest paid: $956
- • Total paid: $5,956
- • Savings: $3,355 in interest!
Real-World Example: Meet Lisa
Lisa has 3 credit cards with a combined balance of $12,000:
Card 1 (Store Card)
Balance: $2,000
APR: 26.99%
Card 2 (Visa)
Balance: $5,500
APR: 19.99%
Card 3 (Mastercard)
Balance: $4,500
APR: 22.99%
Lisa's Options (paying $500/month):
Avalanche Method (Highest APR First)
Order: Card 1 → Card 3 → Card 2
Time: 29 months
Total interest: $2,847
Snowball Method (Lowest Balance First)
Order: Card 1 → Card 3 → Card 2
Time: 29 months
Total interest: $2,912
Lisa's choice: She chose Avalanche to save $65 more in interest. However, both methods get her debt-free in 29 months — a huge improvement over 8+ years with minimum payments!
Balance Transfer Strategy
A balance transfer moves high-interest debt to a new card with a 0% introductory APR (typically 12-21 months). This can save significant interest if you can pay off the balance during the promotional period.
When Balance Transfer Makes Sense
- • You have good credit (670+)
- • You can pay off during 0% period
- • Transfer fee (3-5%) is less than interest saved
- • You won't add new debt
Balance Transfer Risks
- • Deferred interest if not paid in full
- • High APR after promo period (often 20%+)
- • Temptation to use old cards again
- • Transfer fees reduce savings

5 Tips to Pay Off Credit Cards Faster
Pay More Than the Minimum
Even an extra $50-100/month can cut years off your payoff time and save thousands in interest.
Use Windfalls Wisely
Tax refunds, bonuses, and gifts can make a huge dent in your balance. Commit to putting at least 50% toward debt.
Stop Using the Cards
Switch to cash or debit while paying down debt. Adding new charges undoes your progress.
Negotiate a Lower APR
Call your card issuer and ask for a rate reduction. If you have good payment history, you have leverage.
Consider a Balance Transfer
A 0% APR balance transfer can save significant interest if you can pay off the balance during the promotional period.
