Minimum Payment Calculator

Minimum Payment Calculator

Most credit card statements list a minimum payment that looks reasonable — $95, $130, maybe $200 on a larger balance. What the statement does not show is that paying only that minimum on a $5,000 balance at 22% APR will take 27 years and cost more than $14,000 in total payments. This calculator runs that full simulation month by month, showing the true cost of minimum-only payments and exactly how much you save by switching to any fixed payment amount.

How Minimum Payments Are Calculated

Card issuers typically use one of two formulas, whichever produces the higher amount:

Formula 1 (percentage-based): Minimum = Balance x 0.01 to 0.02 (1% to 2% of current balance)

Formula 2 (flat floor): Minimum = $25 to $35, regardless of balance

Each month, the percentage-based minimum drops as the balance decreases. On a $5,000 balance at 2%, the first minimum is $100. After paying that, roughly $8 goes to principal and $92 to interest. The next month’s minimum is $99.84 on the new $4,992 balance. This self-reducing structure is what stretches a modest balance into a multi-decade obligation.

The calculator iterates month by month, applying monthly interest (Balance x APR / 12), subtracting the applicable minimum, and carrying the new balance forward until it reaches zero.

Worked Examples

Example 1 — $5,000 balance, 22% APR

Paying the 2% minimum: starts at $100, declines every month. Payoff time: 27 years. Total interest: $9,020. Total paid: $14,020.

Switching to a fixed $200/month: payoff time 2 years 8 months. Total interest: $1,408. Total paid: $6,408. Savings vs. minimum: $7,612.

Switching to a fixed $300/month: payoff time 1 year 10 months. Total interest: $912. Total paid: $5,912. Savings vs. minimum: $8,108.

Example 2 — $10,000 balance, 24% APR

Paying the 2% minimum: starts at $200, declining. Payoff time: 32 years. Total interest: $20,718. Total paid: $30,718.

Fixed $400/month: payoff time 2 years 9 months. Total interest: $3,168. Total paid: $13,168. Savings vs. minimum: $17,550.

Fixed $600/month: payoff time 1 year 10 months. Total interest: $2,004. Total paid: $12,004. Savings vs. minimum: $18,714.

Example 3 — $2,500 balance, 19% APR, close to the floor minimum

Paying 2% minimum (starting at $50): payoff time 19 years. Total interest: $3,842. Total paid: $6,342.

Fixed $100/month: payoff time 2 years 5 months. Total interest: $828. Total paid: $3,328. Savings vs. minimum: $3,014.

Even on a relatively small balance, the minimum payment path costs three times more than a modest fixed payment.

When to Use This Calculator

• Before deciding to make the minimum payment this month, to see how much that single choice compounds over time
• When comparing the cost of staying on minimums versus committing to a fixed higher payment
• When deciding whether a balance transfer to 0% APR is worth the fee — the minimum payment cost makes the math obvious
• When setting a payoff target and needing to know what fixed payment achieves debt-free status by a specific date
• When explaining to a family member or partner why minimum payments are more expensive than they appear

Common Mistakes

1. Treating the minimum as a reasonable ongoing payment. Card issuers set minimums just above the monthly interest charge — the absolute floor that keeps the account current. It is not a debt reduction strategy; it is the slowest and most expensive path to zero.

2. Continuing to charge new purchases while paying only the minimum. Any new charge at full APR is added to a balance that is already barely decreasing. Adding $200/month in new purchases to a balance that loses $8/month in principal means the balance grows every month indefinitely.

3. Miscalculating payoff speed after a fixed-rate decision. When you commit to a fixed dollar payment (say $250/month), the payoff accelerates as the balance drops because the same $250 now applies more to principal. Many people recalculate and assume payoff takes the same number of months as when the balance was high — it takes fewer.

4. Ignoring the flat floor minimum. Once the balance is small enough that 2% falls below $25, the minimum stays at $25. This means payoff of the last few hundred dollars actually moves faster than the percentage formula suggests — the flat floor effectively forces more principal reduction at low balances.

Current Context for 2026

The average credit card APR reached 21.5% in early 2026, and average household credit card balances hit approximately $6,800. At 21.5% APR, a $6,800 balance paying 2% minimums (starting at $136/month) will take about 30 years and cost roughly $14,700 in interest — more than twice the original balance. Congress passed the Credit Card Competition Act in 2023 but broader rate cap proposals have not advanced as of 2026, meaning high-rate debt remains a persistent cost for millions of households. The minimum payment calculator is particularly relevant now because the combination of high balances and high rates makes the total cost of minimum payments historically steep.

Tips

• Pick a fixed payment that is at least two to three times the current minimum and commit to it — even if the minimum drops to $80, keep paying your fixed amount
• Direct any lump sums (tax refunds average $3,200 for 2025 returns, bonuses, gifts) entirely to the highest-rate card balance to collapse the timeline
• If you have multiple cards, pay minimums on all but one, then direct every extra dollar to the card with the highest APR — this is the avalanche method and minimizes total interest
• Set up autopay for the fixed amount rather than the minimum to remove the monthly temptation to pay less
• Run this calculator again after every $1,000 in principal reduction — the projected payoff date will be noticeably closer, which reinforces the behavior
• A balance transfer to 0% APR is most valuable when you have $3,000+ at 19%+ APR and can make the required monthly payment to clear the balance within the promo period
