Debt Avalanche Strategy
Your cards sorted by APR (highest to lowest):
- Chase Sapphire - 18.5% APR, $5,000 balance
- Amex Blue - 16.2% APR, $3,000 balance
Payment strategy: Make minimum payments on all cards, apply extra $200 to the Chase Sapphire (highest APR). Once paid off, move to the next card.

Credit Card Payoff Guide
Understanding Your Inputs
Card Name/Type: A label for your card (e.g., "Chase Sapphire" or "Discover").
Balance: The current amount of debt on the card.
APR (%): The Annual Percentage Rate—the interest rate charged on your balance. Credit cards typically range from 15% to 25%+.
Minimum Payment: The smallest monthly payment your card issuer requires. Paying only the minimum keeps you in debt for years.
Extra Monthly Payment: Additional funds beyond minimums to accelerate payoff. Applied to the highest APR card first.
The Debt Avalanche Method
The Debt Avalanche is a mathematically optimal strategy to minimize total interest paid:
- Sort cards by APR: Order your cards from highest to lowest interest rate
- Pay minimums on all: Make minimum payments on every card to stay current
- Attack the highest rate: Put all extra money toward the card with the highest APR
- Snowball effect: Once the first card is paid off, apply that payment to the next highest APR card
- Repeat: Continue until all cards are paid off
This method saves the most money on interest because you're always paying down the debt that costs you the most.
Debt Avalanche vs Debt Snowball
Debt Avalanche (Recommended for math)
Pays off highest APR cards first. Saves the most money on interest. Best choice if you want the lowest total cost and can stick with a plan.
Debt Snowball
Pays off smallest balance first for quick wins and motivation. Saves less money but provides psychological boost as cards disappear faster. Good if you need motivation.
How to Use This Calculator
- Enter all your credit card balances, APRs, and minimum payments
- Set an extra monthly payment amount (how much extra can you afford?)
- The calculator shows your payoff date and total interest cost
- Adjust the extra payment to see how much faster you can get debt-free
- The payment schedule shows month-by-month progress
Impact of Extra Payments
Even small extra payments make a huge difference:
Example: $8,000 in credit card debt at 18% APR
- Minimum only ($150/mo): 67 months, $2,100 in interest
- + $100 extra ($250/mo): 35 months, $850 in interest (saves $1,250!)
- + $200 extra ($350/mo): 25 months, $495 in interest (saves $1,605!)
Strategies to Pay Off Faster
- Transfer balance: Move high-APR debt to a 0% intro rate card to save on interest
- Negotiate lower rates: Call your card issuer and ask for a lower APR (works especially well with good credit)
- Find extra money: Sell items, cut spending, pick up a side gig to boost extra payments
- Stop using cards: Freeze spending on cards you're paying off (literally in ice if needed!)
- Windfalls: Tax refunds, bonuses, gifts—put all of it toward debt
- Debt consolidation: Personal loan at lower rate to pay off multiple cards
Why Credit Card Debt is Dangerous
- High interest rates: 15-25%+ means debt grows fast if you only pay minimums
- Minimum payment trap: Paying only minimums extends payoff decades and costs you thousands
- Credit score impact: High card balances hurt your credit utilization ratio
- Spiral risk: High debt + high interest creates a cycle where interest accrues faster than you can pay
- Stress: Debt is a major source of financial anxiety and health problems
Common Mistakes to Avoid
- Running up new debt: The biggest mistake is paying off cards then re-loading them
- Only paying minimums: This keeps you in debt for decades
- Ignoring the plan: Stick to your payoff strategy instead of jumping between methods
- Closing cards too early: Paid-off cards help your credit score—don't close them
- Missing payments: Late payments destroy your credit and add fees
