Minimum payments are designed to keep you in debt as long as possible. On a $5,000 balance at 22% APR, paying only the minimum (typically 2% of the balance) takes over 15 years to pay off and costs more than $4,000 in interest on top of the $5,000 you owe. That's not a glitch in the system. That's the product. This calculator shows you the actual cost of your credit card debt based on how you choose to pay. Enter your balance and APR, then choose a strategy: minimum-only payments, a fixed monthly amount, or a target payoff date. You'll see exactly when you'll be free and how much the debt will cost you in total. The most valuable output is the comparison: see what happens when you add just $50 or $100 per month to minimum payments. The interest savings are often shocking. An extra $100/month on a $5,000 balance can cut years off your payoff timeline and save over $2,000 in interest. Paying down a 22% APR credit card is a guaranteed 22% return on every dollar applied. No investment reliably beats that.
- ·Minimum payment is calculated as 2% of the current balance (or a $25 floor) — actual minimums vary by card
- ·Interest compounds daily based on your APR ÷ 365 applied to the average daily balance
- ·Assumes no new charges are added to the card during payoff
- ·Balance transfer fees and annual fees are not included
Daily periodic rate (DPR) = APR ÷ 365 Monthly interest charge ≈ DPR × 30 × average daily balance For minimum payments: the minimum shrinks as the balance shrinks (typically 2% of remaining balance), which is why payoff timelines extend to 15+ years. For fixed payments: standard amortization applies — payoff date = –log(1 – r×P/M) / log(1+r), where P = balance, r = monthly rate (APR÷12), M = fixed monthly payment. The key insight: because minimums are percentage-based, they create an infinite slow-drain. A fixed payment (even just $200/month on a $5,000 balance at 20% APR) creates a clear debt-free date.
- →Deciding whether to pay down debt or invest — knowing your exact APR cost makes the comparison concrete
- →Setting a payoff goal — enter your target date to find the exact monthly payment required
- →Evaluating a balance transfer offer — compare current payoff cost to the transfer fee + new rate
- →Prioritizing which card to pay first — see total interest cost on each card
- →Building motivation — seeing a specific debt-free date is more actionable than a vague goal
Example 1: $5,000 balance — minimum payments vs. fixed $200
Inputs: Balance: $5,000 · APR: 22.99%
Result: Minimum only: 16+ years · total interest $4,200+ | Fixed $200/month: 30 months · total interest $1,550 · savings: $2,650+
Committing to $200/month (just $100 more than the approximate starting minimum) saves over $2,650 in interest and eliminates the debt 14+ years faster. The extra $100/month has a guaranteed 22.99% return.
Example 2: Setting a payoff goal date
Inputs: Balance: $3,800 · APR: 19.99% · Goal: pay off in 18 months
Result: Required monthly payment: $248 · Total interest: $664
Knowing you need exactly $248/month to be debt-free in 18 months turns a vague goal ('pay off my card') into a specific, achievable action. Set up an autopayment for exactly that amount.
- ✕Making only minimum payments without realizing it extends payoff by 10–15+ years on typical balances
- ✕Using a balance transfer without a payoff plan — if you don't clear the balance before the 0% period ends, the remaining balance resets to a high rate
- ✕Continuing to use the card while trying to pay it down — new charges work against every extra dollar you pay
- ✕Prioritizing the largest balance instead of the highest rate (unless using snowball for motivation)
- ✕Not automating the payment amount — relying on manual payments leads to inconsistency
Why does paying the minimum take so long?
Minimum payments are calculated as a percentage of the current balance (typically 1–3%), so they shrink as the balance shrinks. You're always paying just enough to make very slow progress. On a $5,000 balance at 22%, the initial minimum might be $100 — but as the balance drops to $4,900, the minimum drops to $98. This creates a payoff timeline of 15–25 years.
How is credit card interest calculated daily?
Credit cards use a daily periodic rate: APR ÷ 365. This rate is applied to your average daily balance each month. If you carry a balance, interest compounds daily — interest charges themselves accrue interest. This is why carrying a balance even for one month is costly, and why paying in full each month eliminates interest entirely.
Is a balance transfer worth it?
Often yes, if the math works. A 0% intro APR balance transfer typically charges a 3–5% transfer fee. If the 0% period is long enough to pay off the balance, that fee is your total cost — usually far less than the interest you'd pay otherwise. The risk: if you don't pay it off before the period ends, the remaining balance resets to a high variable rate.
Should I pay off credit cards or invest?
Paying off a 20%+ APR credit card is a guaranteed 20%+ return — better than the long-run expected return of the stock market (~7–10% annually). The math strongly favors paying off high-interest debt first. The one exception: if your employer offers a 401(k) match, capture the full match (it's a 50–100% instant return) before aggressively attacking debt.
What's the difference between the avalanche and snowball method?
Avalanche: pay minimums everywhere, throw extra money at the highest-rate debt first. Mathematically optimal — minimizes total interest. Snowball: pay minimums everywhere, attack the smallest balance first. Psychologically powerful — quick wins maintain motivation. For most people the interest difference is small; choose the method you'll actually stick with.
