Pick the right mode and the right number

Four moves that turn this calculator into a real plan instead of a curiosity.

Pick the right mode and the right number

Pick the mode that matches your question

Use Payoff date when you have a payment in mind and want to know the timeline. Use Required payment when you have a deadline in mind and need to know what to pay each month to hit it. The fields adapt to the mode you pick.

Calculate min vs. type your own

Leave Calculate minimum on if you want the calculator to use a typical 2.5% of balance ($25 floor) as the minimum. Turn it off and type your card's actual statement minimum if it's different. The minimum is the bottom of the comparison; your custom payment is the top.

Try doubling the minimum

The single most informative thing to try first: enter an extra payment equal to the minimum. The interest-saved number that pops out is usually large enough to surprise you, and it costs no more discipline than paying the minimum twice a month.

Read the strategy line under the result

The dark panel includes a one-line insight that flags very high APRs (where a balance transfer or APR negotiation likely beats brute payoff) and tells you the dollar interest saved by your current extra payment. Use it as a sanity check on whether your plan is in the right ballpark.

Credit Card Calculator: Single-Card Payoff Date & Required Payment (2026)

Two questions, one tool. Find the date a single card is paid off given what you can pay, or solve for the payment you need to hit a specific deadline.

What This Credit Card Calculator Does

This credit card calculator handles the two questions a single cardholder usually asks. In Payoff date mode you type a balance, an APR, and a monthly payment, and the calculator returns the month and year the card hits zero, the total interest paid along the way, and a side-by-side with the minimum-payment scenario. In Required payment mode you type a balance, an APR, and a target number of months, and the calculator solves the amortization equation for the exact payment you need to clear the card on schedule.
  • Who it helps:
    A cardholder focused on one specific card who wants either a realistic timeline or a concrete monthly target. Pair it with the multi-card credit cards payoff calculator if you're juggling several balances.
  • What it does not do:
    It does not model promotional 0% intro APR windows, balance-transfer fees, or penalty APR after a missed payment. For balance-transfer modeling and intro periods, use the multi-card credit cards payoff calculator linked below.

How the Math Works

Closed-Form Payoff Time

For a fixed monthly payment, the number of months to clear a balance has a closed-form answer. With monthly rate r = APR / 12, balance B, and payment P:
n=−ln⁡ ⁣(1−B⋅rP)ln⁡(1+r)n = \frac{-\ln\!\left(1 - \dfrac{B \cdot r}{P}\right)}{\ln(1 + r)}

The calculator runs this formula directly. It also runs the same formula with the minimum payment so the result panel can show both timelines side by side. If the payment is below the threshold P ≤ B × r, the argument inside the logarithm goes non-positive and the card never pays off; the calculator flags that case explicitly.

Required Payment Mode (Solving for P)

When you give the calculator a target number of months n, it inverts the same formula to solve for the payment:
P=B⋅r⋅(1+r)n(1+r)n−1P = B \cdot \frac{r \cdot (1+r)^{n}}{(1+r)^{n} - 1}

This is the standard fixed-rate amortization payment, the same equation that produces a mortgage payment from loan amount, rate, and term. The calculator returns the result rounded up to the next whole dollar so a small rounding error doesn't leave a dollar on the card at the end.

Why the Calculator Uses Monthly Compounding

Real card issuers compound interest daily inside the billing cycle (the average daily balance method). The dollar difference between monthly and daily compounding on a typical card is small: about $1 per month per $5,000 of balance. Using monthly compounding here keeps the closed-form formulas above clean and matches what most online amortization tables use, so the numbers line up with what you'll see if you check the result against another calculator. For a tighter daily-rate model and multi-card scenarios, use the multi-card credit cards payoff calculator linked below.

Worked Example, Payoff Date Mode

Take a $5,000 balance at 22% APR with a fixed $150 monthly payment. Monthly rate r = 0.22 / 12 ≈ 0.01833. Plugging into the formula above, n = −ln(1 − 5000 × 0.01833 / 150) / ln(1.01833) ≈ 52 months. Total interest is roughly $150 × 52 − $5,000 = $2,800, more than half the original balance. Bump the payment to $300 and the same formula gives n ≈ 19 months and total interest of about $700. Doubling the payment cuts the timeline by roughly two-thirds and saves around $2,100.

Worked Example, Required Payment Mode

Same $5,000 balance at 22% APR, but now you want it gone in 24 months. Plugging n = 24 into the second formula: P = 5000 × 0.01833 × (1.01833)²⁴ / ((1.01833)²⁴ − 1) ≈ $259. The calculator rounds up and tells you to pay $259 per month for 24 months to clear the card on time, with about $1,219 paid in total interest along the way.

How to Use This Calculator

The fields you see depend on which mode is selected at the top.
  • Payoff date mode:
    Asks for Balance, APR, Min payment (or auto-calculated), and Extra monthly payment. Returns a debt-free date and total interest, plus a comparison against minimum-only payments.
  • Required payment mode:
    Asks for Balance, APR, and Target months. Returns the monthly payment needed to clear the card in that window. The Extra monthly payment field still applies; it's anything above the required payment, used in the comparison panel to show how paying more shortens the timeline further.
  • Calculate minimum toggle:
    When on, uses 2.5% of the current balance with a $25 floor as the minimum payment. When off, uses whatever you type into the Min payment field. Use it on for a typical statement-style minimum; use it off if your card uses a different formula or you want to model a fixed dollar minimum.
  • The chart:
    Plots two balance lines over time: minimum-only payments vs. your custom payment. The gap between the two is the months and dollars saved by paying more. The chart caps at 50 plotted points for performance, so very long timelines are sampled rather than fully drawn.

Required Payment Mode: Working Back from a Deadline

Required payment mode answers a question that comes up more often than the timeline question, but most calculators hide it: I want to be done by month X, what does that actually cost per month? Two examples.
  • "Before the wedding next October":
    A $4,200 balance at 19.99% APR, target 11 months. Required payment ≈ $419/month. If $419 doesn't fit your budget, raise the target months until it does (e.g., 18 months gives a $277 required payment).
  • "By the time my year-end bonus arrives":
    A $9,000 balance at 24.99% APR, target 8 months. Required payment ≈ $1,236/month. The calculator immediately tells you whether the deadline is realistic on your cash flow.
  • Reading the result honestly:
    If the required payment is uncomfortably large, the calculator is doing its job: it's telling you the deadline is too aggressive for the balance and APR. Either extend the target, lower the APR (transfer or negotiate), or both. The math is neutral; it just makes the trade-offs visible.

Why So Much of Your Minimum Payment Goes to Interest

The arithmetic of minimums is brutal in early months because the issuer formula is designed to keep the dollar amount low while still covering the month's interest. A typical issuer minimum is approximately 1% of the balance plus that month's interest, with a $25 floor. (The auto-calculate option in this calculator uses a slightly different rule of thumb, 2.5% of the balance, which produces a similar number for mid-size balances.)
  • The interest share, month one:
    On a $5,000 balance at 22% APR, the first month's interest is about $92. A typical minimum of $142 sends only $50 to principal, so 65% of the payment is interest.
  • The interest share, month 24:
    After two years of minimum-only payments, the balance has barely budged (it's still around $4,400) because the minimum has been shrinking with the balance. The interest share is still over 60% of the payment.
  • What changes when you add even $50:
    On the same $5,000 / 22% APR card, $50 of extra principal in month one means month two starts with a smaller balance, which means slightly less interest, which means slightly more principal next month, and so on. Compounded over a payoff cycle, $50/month extra typically saves $1,500+ in total interest and trims roughly two years off the timeline.

When (and How) to Negotiate Your APR

Calling the issuer for an APR reduction is a high-leverage move that most cardholders never try. It costs ten minutes and you can do it from your couch. Some practical guidance on when it works and how to ask.
  • When it tends to work:
    You've held the card for at least a year, you're current on payments, and you've got at least one competing offer (or a credit score above 700). Issuers track retention metrics and have explicit budgets for keeping accounts open.
  • How to ask:
    Call the customer service number on the back of the card and ask for the retention or hardship team. The script: "I've been a customer for X years and I always pay on time. I've been seeing offers from other issuers around 14%. Can you reduce my APR?" If the first answer is no, ask if there's a temporary hardship rate available.
  • What "yes" usually looks like:
    A 2 to 5 percentage-point reduction is the most common outcome. On a $5,000 balance with a fixed monthly payment, dropping APR from 24% to 19% saves several hundred dollars over a typical payoff and shaves months off the timeline. Plug the new APR into this calculator to see the exact effect.
  • If the answer is no:
    A balance transfer to a 0% intro card is the alternative for a balance you can clear inside the promo window. Use the multi-card credit cards payoff calculator to model the transfer fee and intro period together.

FAQ

How long will it take to pay off my credit card?

It depends on three numbers: your balance, your APR, and how much you actually pay each month. A $5,000 balance at 22% APR with a $150 monthly payment clears in about 4.5 years. Bump the payment to $250 and you finish in roughly 2 years. Use Payoff date mode in the calculator above and try different monthly payments to see your own timeline; the chart shows both the minimum-payment line and your custom line so you can read the time saved straight off the page.

How much do I need to pay each month to be debt-free in a specific number of months?

Switch the calculator to Required payment mode and enter your target number of months. It runs the standard amortization formula in reverse and tells you the exact monthly payment that gets you to zero on schedule. This is the right mode when you want a date in mind (say, "before the school year starts" or "by my next bonus") and need to know what it actually costs each month to hit that date.

Why is so much of my minimum payment going to interest?

Because the minimum is sized just barely above the monthly interest charge. A typical issuer minimum is around 1% of the balance plus that month's interest, with a $25 floor. On a $5,000 balance at 22% APR, the first month's interest alone is about $92, and the minimum might be $142, of which only $50 actually reduces the balance. As the balance shrinks, the dollar amount going to principal grows, but it takes years to get meaningful traction. That's why even small extra payments produce outsized savings.

Can I really call my credit card company and ask for a lower APR?

Yes, and a meaningful share of cardholders who ask actually get a reduction. Call the number on the back of the card, ask for the retention or hardship team, and frame it as "I've been a customer for X years, I pay on time, and I'm looking at offers from other issuers." A 2 to 5 point APR drop is realistic. Even a temporary hardship rate (often 6-10% for 6-12 months) can save hundreds while you focus on payoff. Worst case they say no, and you're no worse off.

Should I make extra payments on my card or build an emergency fund first?

Build a small starter emergency fund (often $1,000 to $2,000, or one month of essential expenses) before throwing everything at the card. The reason is mechanical, not emotional: without a buffer, an unexpected expense lands back on the card and undoes your progress. Once that buffer exists, every spare dollar above the minimum is worth more in interest savings than it could plausibly earn in a savings account at today's rates.

Will paying off this card actually improve my credit score?

Almost always yes, often noticeably. Credit utilization (your balance divided by your credit limit) accounts for about 30% of a FICO score. Dropping a card from 70% utilized to under 30% commonly produces a 20-50 point bump within one or two billing cycles, with no other changes. Just don't close the card after you pay it off; the limit it provides keeps your overall utilization low going forward.

When does a balance transfer make sense vs. just paying this card off?

A balance transfer is worth it when the interest you'd save during the 0% promo window clearly exceeds the upfront transfer fee (commonly 3-5% of the transferred balance), and you're confident you can clear the balance before the promo ends. If you're juggling several balances or want to model a transfer end-to-end, the multi-card credit cards payoff calculator linked below has fields for the intro APR, intro months, and transfer fee. For a single card you'll keep, often the cheapest move is an APR negotiation or just disciplined extra payments here.
