How to calculate your credit card monthly repayment

Calculate the minimum monthly payment for your credit card and work out how much you should be paying to take control of your debt.

When you look at your credit card statement each month, you'll see both the closing balance and a "minimum monthly repayment" amount. While the closing balance is everything you owe, the minimum repayment shows what you have to pay off the card by the due date in order to keep your account in good standing.

Although making minimum repayments gives you the flexibility to pay off your balance over time, it can also lead to ongoing credit card debt, interest charges and other risks. Use this guide to learn how minimum repayments are set and what happens if this is all you pay each month. We also look at how to calculate your credit card minimum repayment and ways to save money so that you can make your credit card work for you.

What is the minimum I need to pay on my credit card?

Your card issuer sets the minimum monthly repayment on your credit card. This amount varies between credit card issuers but is usually calculated as 2–3% percent of your closing balance, with a minimum dollar charge of around $20 to $30.

To give you an idea of these costs, here are the minimum monthly repayment requirements of some popular credit card issuers:

  • American Express credit cards: The higher of $30 or 2.5% of your closing balance
  • ANZ credit cards: The higher of $25 or 2% of the closing balance
  • CommBank credit cards: The higher of $25 or 2% of the closing balance
  • NAB credit cards: The higher of $25 or 2% of the closing balance
  • St.George credit cards: The higher of $10 or 2% of the closing balance
  • Westpac credit cards: The higher of $10 or 2% of the closing balance

Every time you get a credit card statement, the minimum repayment amount will be shown in dollars. This means you won't have to calculate the percentage owed if you carry a balance.

Will I be repaying my credit card debt if I just pay the minimum?

If you only make the minimum monthly payment, you will still pay off some of the money you owe but a large portion of your repayment will go towards paying off interest charges. This is because there are two factors that make up your minimum monthly repayment amount: the balance portion and the interest portion.

With so much of your minimum repayment going towards interest charges, it's ideal for you to aim to pay your credit card balance off in full each month. This helps you avoid more interest charges and debt.

What will happen if I just make the minimum credit card repayment?

While it may sometimes be tempting to only make the minimum monthly repayment on your credit card, you should avoid doing this whenever possible for a few reasons:

  • Repayment takes longer. It will take you a much longer time to repay the money you owe. Depending on your balance and the card’s interest rate, this could add several years to your repayment period.
  • It costs more. The longer you carry a debt on your credit card, the more interest will be charged to your account. This means your credit card debt could end up costing you thousands of dollars more and will take much longer to pay back.
  • It will affect your credit score. If you continually carry a balance on your credit card that takes up a large portion of your overall card limit, this can impact on your credit score.

If you want a better idea of just how much only making the minimum credit card repayment will affect your finances, check your credit card statement. This shows how long it will take you to repay your debt if you only repay the minimum as well as the total interest you will have to pay.

Matt’s minimum repayments

Matt is a 30-year-old teacher from Brisbane who has a $5,000 debt on a credit card with an interest rate of 15% p.a. He wants to pay this off by working out the most efficient way to pay down his debt.

The minimum monthly payment on his latest credit card statement is $102 (2% of his closing balance) but Matt decides to calculate how much he can save if he starts putting money aside and paying $250 off his card each month. He draws up a table to calculate the costs of his minimum and higher credit card payments.

If making minimum monthly repaymentsIf making higher monthly repayments
Credit card debt$5,000$5,000
Interest rate15% p.a.15% p.a.
Monthly repayment amount$102 (initially - amount decreases each month as closing balance also drops)$250
Total time to pay off debt23 years 10 months1 year 11 months
Total amount paid$12,030$5,707
Total amount saved-$6,323

As you can see from the table, Matt can save a massive $6,323 by making higher repayments and paying his debt off in less than two years. However, if he were to continue to only make the minimum required payment, it would take Matt almost 24 years to get out of debt. This clearly demonstrates why you should always try to pay more than the minimum monthly payment if possible.

Paying down a credit card debt with a promotional interest rate

Some credit cards offer promotional interest rates that apply to purchases or balance transfers during the introductory period. These offers can help you save money if you know you need to use your card to pay for something, or if you have existing debt you want to pay off.

If you're interested in getting a credit card with a low or 0% introductory interest rate, make sure you think about the following factors when calculating your repayments:

  • Revert rate. While 0% p.a. interest may apply to your balance transfer or purchases now, you need to be aware of what interest rate the card will revert to once the promotional period ends.
  • Length of promotional period. How long does the low or zero interest period last? Depending on the credit card you select, these introductory promos last for anywhere between 3 and 24 months. The revert rate will apply to your balance as soon as the promotional period ends, so you will want to pay off your debt before that occurs.
  • Additional purchases. If you make more purchases on your credit card, your total balance and minimum monthly payment will both increase. You will need to be aware whether your minimum monthly payments will then go towards paying off your initial balance or towards repaying your new purchases.
  • Annual fee. Most credit cards charge an annual fee when you first open your account and then every 12 months on the anniversary of that date. This could add to your balance when you get a card that offers 0% interest during the introductory period, so make sure you factor that cost into your repayments.

Finally, it’s crucial to be aware that making only the minimum repayment each month will not result in the debt being paid down within the promotional period. This means that a higher revert rate will apply to your balance at the end of the introductory period, which will increase the amount you need to repay and could lead to further debt.

    Could you please advise me in this regards ?
    Eg: I got a balance transferred credit card with $1200 debt.

    BT 0% period is 12 months.

    I have to pay $100 each month to completely pay off $1200 debt.
    Instead I will pay the minimum monthly payment of $24 (2% of $1200).

    Should I pay interest for the rest of the amount $76 ($100-$24) due ?

      Hello Sesha,

      Thank you for sending your inquiry today.

      Assuming the figures you mentioned, it would depend whether or not the $24 meets the minimum due on your card.

      1. Yes? – Not yet, as the unpaid balance will likely be charged “deferred interest” at the end of your 12 months promo period should you not be able to catch up in paying them completely.
      2. No? – This is bad. It may cause the creditor to pull you out of the promo period immediately as you’re overdue. This will cause the entire balance to be assessed for interest, making your future minimum payments larger.

      It is very important that you consider your cash flow before committing into any balance transfer arrangement. If you need a longer term, you may consider checking this page.

      Hope this helps.

    I want to work out how much monthly payment will come to for $6000 balance on a 0% balance transfer for 12 months ?

      Hi, Kumar.

      Thanks for your question.

      You will need to pay back at least the minimum monthly repayment each month. This is a percentage (usually 2 or 3 percent) of your total outstanding balance. This is the minimum you must pay each statement period, you’re free to pay as much over this as you would like, as often as you like.

      I hope this helps.
