What’s the best way to pay off credit card debt?

Two popular strategies are Snowball (tackle the smallest balance first) and Avalanche (tackle the highest APR first). Avalanche usually saves more interest, while Snowball can feel more motivating. The best method is the one you can stick with consistently.

What happens if my payment doesn’t cover interest?

If your payment is less than the monthly interest, your balance grows (negative amortization). Try increasing your payment or adding an extra payment so that principal is reduced each month.

Should I consolidate debt?

Consolidation can reduce interest and simplify payments if you qualify for a lower APR and avoid adding new debt. Compare total costs and fees, and run the numbers in this calculator to confirm savings.

How this calculator works

We compound interest monthly using your APR. If your payment is below monthly interest, increase it to avoid negative amortization.

Smart Repayment Strategies

Debt Avalanche (Mathematically Fastest)

Pay the minimum on all cards and put every extra dollar toward the highest APR. Once it’s gone, roll that payment into the next-highest APR. This minimizes total interest paid.

Debt Snowball (Motivation First)

Pay the smallest balance first for quick wins, then snowball the freed-up payment into the next balance. You may pay slightly more interest, but many people find it easier to stick with.

Hybrid Approach

Rank cards by APR, but if two are close, clear the smaller balance for a psychological boost. The calculator can model either plan—just adjust extra payment allocations.

APR, APY, and the Daily Periodic Rate

APR is the nominal yearly interest rate used by card issuers. Interest actually accrues using a daily periodic rate (APR÷365) on your average daily balance. APY reflects compounding and is higher than APR at the same nominal rate.

Example: 24% APR → ~0.06575% per day. A \$2,000 revolving balance accrues about \$1.32 interest per day before payments. Avoid compounding by paying down earlier in the cycle.

Fees and Common Traps

Late fees: Trigger penalty APRs that can exceed 29.99%—set up autopay for at least the minimum.
Cash advances: Interest starts immediately with no grace period and often higher APR + fees.
Balance transfers: 0% promos are great, but mind the transfer fee (usually 3–5%) and the end date.
Deferred interest offers: If any balance remains at promo end, interest can retroactively apply.

Optimize Your Payoff Plan

Round Up Payments

Rounding \$238 → \$250 can shave months off a payoff timeline with minimal budget impact.

Multiple Payments per Month

Splitting your extra into two payments reduces average daily balance and total interest.

Windfalls to Debt

Tax refunds, bonuses, or side‑gig income applied as lump sums dramatically shorten payoff time.

Freeze New Spending

While you’re in payoff mode, move everyday purchases to a debit card to prevent balance re‑growth.

Real‑World Scenarios

Scenario A: \$6,000 at 24% APR, paying \$300/mo → roughly 26–27 months if you avoid new spending. Increase to \$350/mo and finish about 5 months faster.

Scenario B: Two cards—\$2,500 at 29% APR and \$3,500 at 18% APR. Avalanche knocks out the 29% card first, saving ~\$200–\$300 interest versus snowball (varies by timing).

Quick FAQs

Does paying earlier in the month help?

Yes. Interest is computed daily. Earlier pay‑downs reduce the average daily balance for the cycle.

Should I close paid‑off cards?

Often no. Keeping older accounts open can help credit age and utilization. If there’s a high annual fee and no value, consider downgrade options.

What minimum payment should I assume?

Most issuers use 1–3% of balance or a fixed floor. Try 2% as a planning baseline if you don’t know the exact formula.
