Common Mistakes to Avoid
⚠️
Making only minimum payments
Minimum payments are designed to keep you in debt for decades. Even an extra $50/month can save thousands in interest.
⚠️
Not stopping new charges
Paying down a card while charging more is a treadmill. Freeze the card or cut it up while in payoff mode.
Frequently Asked Questions
How long to pay off credit card debt? ▾
Use this calculator. At 22% APR, a $5,000 balance takes 26 months at $250/month but costs $1,493 in interest.
Best strategy: avalanche or snowball? ▾
Avalanche (highest rate first) saves the most money. Snowball (smallest balance first) builds motivation. Both work — consistency is key.
What if I can't make minimum payments? ▾
Call the credit card company immediately — many offer hardship programs. Consider a non-profit credit counselor (NFCC) or balance transfer.
