How Is the Minimum Payment Calculated on a Credit Card?
The minimum payment on a credit card is the smallest amount you must pay each billing cycle to keep your account in good standing and avoid a late fee. Knowing exactly how your minimum payment is calculated helps you understand why it's so hard to pay off credit card debt — and why paying more is almost always worth it.
Credit card issuers use one of three main methods to calculate your minimum payment. The exact formula for your card is disclosed in your cardmember agreement. Here's how each method works with real numbers:
The 3 Methods Credit Card Companies Use to Calculate Minimum Payments
Flat Percentage of Balance
Most common method — used by many major issuers
Formula: Balance × percentage rate (typically 1%–3%)
Example: $5,000 balance × 2% = $100 minimum payment
As your balance decreases, so does your minimum — extending payoff time dramatically.
Percentage of Balance + Interest + Fees
Required by regulations — ensures you always cover interest
Formula: (1% of balance) + monthly interest charge + fees
Example: $5,000 balance at 20% APR
= $50 (1% principal) + $83.33 (monthly interest) = $133.33 minimum
This method ensures you're always paying down some principal on top of interest.
Floor (Flat Dollar) Minimum
A safety net minimum that kicks in on smaller balances
Formula: Greater of ($25–$35 flat amount) OR the percentage-based calculation
Example: If 2% of your $800 balance = $16, but your floor is $25, you owe $25
Always pay whichever amount is higher to avoid late fees.
How to Calculate Your Minimum Credit Card Payment: Step-by-Step
You don't need a finance degree to calculate your minimum payment. Follow these steps to figure it out manually, or use the calculator above for instant results.
Find your statement balance
Log into your account online or check your paper statement. Use your current statement balance — not your credit limit.
Locate your card agreement's minimum payment formula', desc: 'Check your cardmember agreement or the fine print on your monthly statement. It will state the exact formula your issuer uses.
Multiply balance × percentage
If your issuer uses a flat percentage (e.g., 2%), multiply: $3,500 × 0.02 = $70.
Add interest charges if required', desc: 'If your issuer uses Method 2, also add this month's interest: ($3,500 × 20% APR) ÷ 12 = $58.33. Total minimum = $70 + $58.33 = $128.33.
Compare to the floor minimum', desc: 'If your calculated amount is less than the card's floor minimum ($25–$35), you owe the floor amount instead.
Verify against your statement
Your statement will always show the exact minimum payment due. The calculation above should match within a dollar or two.
Quick Formula Reference
Minimum Payment = MAX(Floor Amount, Balance × Rate%)

Minimum Payment = MAX(Floor Amount, (1% × Balance) + Monthly Interest)
