Formula & methodology

Formula used

Interest charged each month

interest = balance × (annual rate ÷ 12)

Interest is charged on the balance carried, then the repayment is applied to what remains.

Does the payment clear the card at all?

payment > balance × (annual rate ÷ 12)

If the repayment does not exceed the first month’s interest, the balance grows indefinitely and the card is never paid off. The calculator reports "Never" and shows the shortfall rather than returning a misleading number of years.

Payoff time

balance is reduced month by month until it reaches zero

Simulated month by month, so extra repayments take effect immediately rather than being averaged.

Variable definitions

Symbol	Meaning	Unit
balance	Card balance. amount currently owing	AUD
annual rate	Purchase interest rate. the rate on the balance you carry	% p.a.
payment	Monthly repayment. base repayment plus any extra amount	AUD

Step-by-step calculation

1. Enter the balance and rate
Use the purchase rate that applies to the balance you actually carry.
2. Enter what you repay each month
Add an extra amount to see how much sooner the card clears.
3. Read the payoff time and total interest
If the payment cannot clear the card, the calculator says so explicitly.

Limitations

A single interest rate is applied to the whole balance. Real cards often carry purchases, cash advances and balance transfers at different rates, and cash advances usually attract interest from the day of the transaction with no interest-free period.
Minimum repayments are not modelled as a shrinking percentage of the balance. Paying only the minimum takes far longer than a fixed repayment of the same starting size, because the required amount falls as the balance does.
New spending on the card is not modelled. Continuing to use the card while paying it down changes the outcome substantially.
Annual fees and late-payment fees are not included.

Help & FAQs

Frequently Asked Questions

Clear answers to common questions to help you use this calculator confidently.

What results does this credit card payoff calculator show?

Tap to view the answer

The calculator shows an estimated time to repay, total interest paid and total amount repaid. This helps you understand the cost of carrying credit card debt over time.

Does this calculator follow Australian minimum repayment practices?

Tap to view the answer

Yes. It can model minimum repayments based on a percentage of the balance or a fixed dollar amount, which are common in Australia. Exact rules may differ by provider.

What happens if I only pay the minimum amount?

Tap to view the answer

Paying only the minimum usually results in a much longer payoff period and higher total interest. The calculator shows this impact clearly.

What happens if I stop using the card and make no new purchases?

Tap to view the answer

If no new spending is added, repayments go directly toward reducing the balance. This generally leads to faster payoff.

Does this credit card payoff calculator include taxes or inflation?

Tap to view the answer

No. The calculator shows nominal values and does not adjust for tax or inflation. These factors should be considered separately.

How to Use This Calculator

Enter your balance & rate

Add your current credit card balance and the interest rate you're paying (check your latest statement).

Set your repayment amount

Enter your regular monthly payment – start with what you can afford, then see what extra repayments could do.

Review your debt‑free plan

See exactly when you'll be debt‑free, how much interest you'll pay, and how extra repayments can save you thousands.

Understanding Your Results

Payoff Time
The number of months until your balance reaches zero. This is your 'debt‑free date' – track it and celebrate each payment.
Total Interest Paid
The total interest cost over your payoff period. With Australian rates at 18‑22%, interest can double the cost of your purchases.
Total Amount Paid
Your original balance plus all interest – the true cost of your credit card debt.
Interest Saved (Extra Repayments)
How much you save by paying more than the minimum. Even $20 extra per month can save hundreds over the life of the debt.

Key Tips

✓
Pay more than the minimum – minimum payments are designed to keep you in debt for years. Double your payment and halve your interest.
✓
Consider the 'debt avalanche' method – pay off the highest‑interest card first while paying minimums on the rest.
✓
Balance transfers with 0% interest can be a game‑changer – but only if you repay the balance before the promo period ends.
✓
Stop using the card while you're paying it off – new purchases often don't have interest‑free days until the balance is cleared.
✓
Set up automatic payments to avoid missing a payment – late fees and interest rate hikes can derail your plan.
✓
Review your interest rate annually – if you've been a good customer, call your bank and ask for a lower rate.
✓
Use the 20/10 rule: never borrow more than 20% of your annual income, and keep monthly debt payments under 10% of your take‑home pay.

Credit Card Debt in Australia – The Ultimate 2026 Payoff Guide

The Real Cost of Credit Card Debt in Australia

Australian credit cards typically charge 18‑22% p.a. interest, with some store cards exceeding 25%. On a $5,000 balance at 20% interest, paying only the minimum (2% of balance) takes over 30 years and costs more than $10,000 in interest – meaning you'd pay triple the original amount. This calculator helps you avoid this trap and take control.

How Credit Card Interest Works – The Daily Compounding Trap

Unlike many loans, Australian credit cards compound interest daily and charge it monthly. This means interest is calculated on your balance each day, including on interest from previous days. The 20% p.a. rate is actually 0.055% per day – but compounded daily, it adds up quickly. The best way to avoid this: pay your balance in full each month, or use this calculator to plan a rapid payoff.

Minimum Payments – Why They're a Trap

Banks set minimum payments as a percentage of your balance (usually 2‑3%). This is designed to keep you paying interest for decades. For a $5,000 balance at 20% interest with a 2% minimum ($100), your first month's interest is ~$83 – you're only reducing your principal by $17. This is why so many Australians stay in revolving credit for years. Always pay as much as you can afford.

Balance Transfers – The 0% Interest Opportunity

Many Australian credit cards offer 0% balance transfers for 12‑18 months. This can be a powerful tool: transfer your balance to a 0% card, then aggressively repay during the promo period. But watch out – if you don't repay in full by the end, you'll be hit with the standard rate (often 20‑22%) on the remaining balance, sometimes retroactively. Use this calculator's balance transfer feature to plan your repayment.

Debt Repayment Strategies – Avalanche vs. Snowball

The 'debt avalanche' method: pay off the card with the highest interest rate first while paying minimums on others – this saves the most money. The 'debt snowball' method: pay off the smallest balance first for psychological wins. Both work – choose what motivates you. Our calculator helps you model both approaches and see which gets you debt‑free faster.

Extra Repayments – The Wealth Builder

Even small extra repayments create massive savings. On a $5,000 balance at 20% interest with a $200 monthly payment, adding just $20 extra per month saves $350 in interest and reduces your payoff time by 6 months. Add $100 extra and you save $1,300+ and finish 15 months earlier. Use this calculator to find your optimal extra repayment amount.

How to Use This Calculator for Your Debt‑Free Journey

Start by entering your current balance and interest rate (find these on your statement). Then experiment with different repayment amounts – see how extra payments reduce your interest and payoff time. Try the balance transfer feature to see if switching cards could work for you. Finally, commit to a plan, set up automatic payments, and watch your debt shrink.
