Credit Card Minimum Payment Calculator

This credit card minimum payment calculator answers two questions at once: how long it takes to clear a balance making only the minimum payment, and how much faster (and cheaper) it gets if you pay a fixed amount above that. Enter four numbers, and the tool runs a month-by-month simulation of both scenarios.

1. Enter your credit card balance. Use the statement balance from your most recent bill, or the live balance from your online account. If you have several cards, run each one separately. The minimum payment formula is per-card, not per-issuer.
2. Enter the APR. Your APR is printed on every monthly statement, often inside a section labeled "Interest Charge Calculation." The US average on interest-bearing accounts is currently around 22% to 23%. Store cards regularly run 28% to 31%. Use the purchase APR unless you are paying down a cash advance, which usually has a higher rate.
3. Set the minimum payment percent. Most issuers use 1% to 2% of the principal balance, plus accrued interest and any fees, with a flat floor of $25 to $35. The default of 2% is a reasonable rough match for issuers like Discover. For a more accurate number, find the "minimum payment" line on your statement and reverse-engineer the percentage from your current balance.
4. Enter a fixed higher payment. Try the largest number your budget supports. Even paying $50 above the first minimum can cut years off the payoff and save thousands in interest. The calculator will reject any payment that does not cover the monthly interest charge, because the balance would never fall.
5. Read the comparison panel. The Payoff Comparison table shows months, years, total interest, and total paid for each strategy side by side. The green callout below summarizes how much you save and how many months sooner you finish.
6. Scroll to the schedule. The 36-month minimum payment schedule shows exactly where your money goes each month. In the first year of paying minimums on a $5,000 balance at 22% APR, more than 90% of every payment goes to interest. The principal column makes that hard to argue with.

The preset row above the schedule is the most useful piece of the page. It runs the math for the same balance and APR with four extra-payment scenarios on top of the first minimum. Most people are surprised at how much an extra $25 or $50 a month changes total interest. That single insight is the entire reason this minimum payment calculator exists.

Credit card minimum payments are deliberately small. After the 2009 CARD Act, federal rules require issuers to set a minimum that at least covers the current month's interest, fees, and a small slice of principal, but they are free to make that slice as thin as they want. Most do, because the longer you carry a balance, the more interest they collect.

Monthly Interest and Daily Compounding

Daily Periodic Rate (DPR) = APR ÷ 365
Monthly Interest         = Average Daily Balance × DPR × Days in Cycle

Example: 22% APR, $5,000 average balance, 30-day cycle
DPR              = 0.22 ÷ 365 = 0.0006027 (0.06027% per day)
Monthly interest = 5,000 × 0.0006027 × 30 ≈ $90.41

Most online calculators (this one included) approximate that with a flat monthly rate of APR ÷ 12 to keep the math readable. The number is within a few cents of the true daily-compounded figure for typical balances and APRs.

The Minimum Payment Formula

Minimum Payment = greater of:
  (a) Flat floor          ($25 to $35, set by issuer)
  (b) % of balance + interest + fees
      (typically 1% to 3% of principal,
       plus current interest and any past-due fees)

The formula has one big consequence: as your balance shrinks, the percentage piece shrinks with it. A $5,000 balance at 2% gets a $100 principal slice. A month later, when the balance is $4,910, that slice is $98.20. That decay is the "shrinking minimum" trap, and it is the reason a minimum-only payoff stretches to 15, 20, or even 30 years.

Issuer-Specific Formulas (2025)

Each card network sets its own minimum payment formula. The exact wording is in your cardmember agreement, but here is the rough shape for the major US issuers:

If your balance is small enough that 1% to 2% lands below the flat floor, the floor takes over and the minimum stops shrinking. For most balances above $2,500, the percentage piece dominates and the shrinking effect is in full swing.

Worked Example: $5,000 at 22% APR, 2% Minimum

Month 1
  Interest       = $5,000 × (0.22 ÷ 12)        = $91.67
  Min payment    = max($5,000 × 0.02, $25)     = $100.00
  Principal paid = $100 - $91.67               = $8.33
  New balance                                  = $4,991.67

Month 2
  Interest       = $4,991.67 × 0.01833         = $91.51
  Min payment    = max($4,991.67 × 0.02, $25)  = $99.83
  Principal paid = $99.83 - $91.51             = $8.32
  New balance                                  = $4,983.35

Month 12
  Balance        ≈ $4,896
  Min payment    ≈ $97.92
  Principal paid ≈ $8.18  (still!)

After a full year of minimums, the balance drops about $104. The other ~$1,070 you paid went to interest. This is the math the calculator above runs forward 200+ months until the balance hits zero, which is when the actual payoff happens, somewhere between year 18 and year 25 depending on the exact issuer formula.

Quick Reference: $5,000 at 22% APR by Monthly Payment

Same balance, same APR, four different monthly payments. The total interest column is the lever you actually control:

Going from the minimum to a fixed $200 payment cuts total interest from roughly $5,800 to roughly $1,397, a savings near $4,400, and shortens payoff from over two decades to under three years. That gap is the reason the credit card minimum payment calculator is one of the highest-leverage tools on this site.

The numbers above are the easy part. What the calculator cannot tell you is which strategy makes sense for your situation, what to do if you cannot afford the minimum, and how the minimum payment shows up on your credit report. This section covers the parts that make the math actionable.

What the "Minimum Payment Warning" Box on Your Statement Means

Since the 2009 CARD Act, every US credit card statement is required to include a box that shows two numbers:

• How long it will take to pay off the current balance making only the minimum payment, and how much you will pay in total.
• The fixed monthly payment that would clear the balance in 36 months, and how much that costs in total.

For a $5,000 balance at 22% APR, the box typically reads something like: "If you make only the minimum payment, you will pay off the balance in about 22 years and pay roughly $10,800 total. To pay off in 3 years, pay $191 per month and pay roughly $6,876 total."

The 3-year column is a much better target than the minimum. Most people who carry a balance can afford the 3-year number with a small amount of budget reshuffling. If yours is a large balance and the 3-year payment looks impossible, drop to a 5-year fixed payment instead. Anything that beats the shrinking minimum saves thousands.

Why Your Minimum Keeps Shrinking

The minimum is recalculated every month based on the new balance. As you make payments, the balance falls, the 1% to 2% slice falls with it, and the dollar minimum drops too. That sounds harmless, but the effect is brutal: each shrinking payment leaves more dollars in the balance to accrue interest the following month, which keeps the principal high, which keeps interest charges high. The decay never stops compounding against you.

The fix is simple. Pick a fixed dollar amount that does not move when the minimum drops. Even "the first minimum" held flat for the entire payoff cuts years off the timeline, because by year three your minimum would have shrunk to half of that number, but you are still paying the original amount.

How $25 Extra Changes Everything

Most personal finance advice is too vague to act on. Here is the specific number for a typical card. On a $5,000 balance at 22% APR with a 2% minimum, paying just $25 above the first minimum, held flat each month, takes the payoff from roughly 22 years and $5,800 of interest down to about 4 years and $1,200 of interest. The extra $25 a month, $1,200 over 4 years, saves more than $4,500 in interest. There is no investment account on Earth that returns 4x your contribution risk-free, but credit card payoff math does, and most people leave that return on the table.

What If You Cannot Afford the Minimum Payment?

Missing a minimum payment by 30 days hits your credit score hard, often 60 to 110 points for an account in good standing, and triggers late fees of $30 to $40. Before that happens, call the card issuer. Most major banks offer hardship programs that pause interest, lower the APR, or freeze the account at a fixed payment for 6 to 24 months. They are not advertised, but every issuer has a hardship workflow. The phone call is short and they care more about getting paid than about fees.

Other options if a hardship program is not enough: a 0% balance transfer card (if your credit is still strong enough to qualify), a personal loan to consolidate at a lower fixed rate, a debt management plan through a nonprofit credit counselor (NFCC member agencies are the standard), or, as a last resort, debt settlement or bankruptcy counseling. Each has trade-offs. The mistake is doing nothing while late fees and credit damage stack up.

Does Paying Only the Minimum Hurt Your Credit Score?

Not directly, no. The credit bureaus do not track whether you paid the minimum or paid in full. They track whether you paid on time and what your utilization ratio is on the day the issuer reports your balance.

The indirect damage is real, though. Paying minimums keeps your balance high. A high balance keeps your utilization ratio high. Utilization is the second-largest factor in your FICO score, behind on-time payments. Once utilization crosses 30% on any single card or across all cards combined, scores drop. At 50% utilization the drop accelerates, and at 80%+ scores can fall into the 600s even for borrowers with perfect payment history.

Paying more than the minimum lowers utilization, which improves your score. Paying the statement balance in full each month puts utilization at 0% on that account, which is optimal.

When the Minimum Is Larger Than 1% to 2%

Three situations push your minimum above the standard formula:

• You went over your credit limit. The over-limit amount usually gets added to the minimum. If your limit is $5,000 and your balance is $5,200, the next minimum will include the $200 overage on top of the normal slice.
• You are past due. Any missed minimum from a previous month gets rolled into the current one, plus a late fee.
• You have a promotional APR ending. Some issuers raise the minimum slightly when a 0% promo expires, to start chipping at the new accruing interest faster.

If your minimum jumped without explanation, log into the account and check for any of these three. The formula in the cardmember agreement always controls.
