3. The Mathematics of Daily Compound Interest & Amortization
Daily Interest Charge (I_daily) for balance (B), annual interest rate (r_annual), and Months to Pay Off (N) under fixed monthly repayment (M_fixed) are:
Example Calculation ($5,000 Balance @ 19.99% p.a. Interest, Fixed $255/mo Payment):
- Monthly Interest Rate: 19.99% ÷ 12 = 1.6658% / month.
- Months to Zero Balance: Exactly 24.0 Months (2 Years).
- Total Interest Paid over 2 Years = ($255 × 24) - $5,000 = $1,120 Total Interest.

Frequently Asked Questions (FAQ)
What is the "Minimum Repayment Trap" on Australian credit cards?
The Minimum Repayment Trap occurs when cardholders pay only the minimum required monthly percentage (typically 2%–3% of balance). On a $5,000 balance at 19.99% interest, making only minimum payments takes over 25 YEARS to pay off and costs over $8,000 in interest alone.
How much interest can you save by fixing your monthly payment to pay off a credit card in 2 years?
Fixing your repayment to $255/month on a $5,000 balance at 19.99% pays off the card in exactly 24 months, costing $1,118 in total interest—saving over $7,000 compared to minimum repayments.
How do 0% Balance Transfer credit cards work in Australia?
A 0% Balance Transfer allows you to transfer existing credit card debt to a new card charging 0% interest for a promotional period (e.g. 12 to 28 months). Watch for balance transfer handling fees (typically 1%–3%) and revert interest rates.
What is the difference between Purchase Rate and Cash Advance Rate?
Purchase Rates apply to standard retail store card purchases (e.g. 17.99%–21.99%). Cash Advance Rates apply immediately when withdrawing cash from an ATM or transferring funds into a bank account (e.g. 22.99%–25.99%, with no interest-free grace period).
How does closing unused credit card accounts affect your credit score in Australia?
Closing unused credit cards reduces your total available credit limit and lowers your debt-to-income ratio, improving your borrowing capacity when applying for home loans or mortgage finance.
