$15,000 in credit card debt at 22% APR with a $300 minimum payment will take over 7 years to pay off and cost you more than $11,000 in interest if you only pay minimums. But add just $200 extra per month and you pay it off in under 3 years and save $7,000 in interest. The math is on your side — if you move fast.

If you have multiple cards, list them by interest rate highest to lowest. Pay minimums on all of them, then throw every extra dollar at the highest rate card. When it is gone, roll that payment to the next card. This is the mathematically fastest path out.
Audit your subscriptions — most people find $50-150/month they forgot about. Cut one restaurant meal per week — saves $100-300/month for most families. Sell unused items — one weekend can generate $200-500. Even finding $150 extra per month cuts your payoff time nearly in half.
If your credit score is 680 or above, a 0% APR balance transfer card could eliminate interest entirely for 12-21 months. On $15,000 that saves $2,700-4,000 in interest during the promo period — letting every dollar you pay reduce principal directly.
Here's the full picture at 22% APR with a $300 minimum payment, so you can see exactly what each extra-payment level buys you:
Notice the pattern: the jump from minimums to $100 extra saves more than the jump from $200 to $400 extra. The first extra dollars you add do the most work — which is worth knowing if you're deciding how aggressively to cut your budget.
At minimum payments alone, over 7 years. With $200 extra per month, under 3 years. The timeline shrinks dramatically with even modest extra payments because you're cutting into a 22%+ APR that compounds against you every month you carry a balance.
Worth considering if you can qualify for a rate meaningfully below your current card APRs — often personal loan rates land in the 10-16% range for good credit, well under typical 22-26% card rates. Run the math on your specific offer before committing, since origination fees can eat into the savings.
Concentrate extra payments on one card at a time — either the highest rate (avalanche, saves the most money) or the smallest balance (snowball, builds momentum faster). Spreading extra payments thin across multiple cards slows down payoff on all of them.
Generally yes, and often significantly — credit utilization (how much of your available credit you're using) is one of the biggest scoring factors, and dropping a large balance to zero typically produces a noticeable score increase within one to two billing cycles.
Start smaller than you think — even $50 extra per month meaningfully changes the timeline. Combine that with a spending audit (subscriptions, dining out) before assuming there's truly nothing available; most people find something.
Not significantly for the math, but paying as soon as you have the funds available (rather than waiting for your statement due date) can reduce the average daily balance your interest is calculated on, saving a small amount extra.
