4. Using the Calculator

Tips: Enter your current credit card balance in NZD, your planned monthly payment in NZD, and your card's annual interest rate (APR). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why does the calculator say "Payment too low"?
A: If your monthly payment doesn't exceed the monthly interest charges, your balance will never decrease. You need to pay more than the interest each month.

Q2: What's a typical credit card APR in NZ?
A: As of 2024, most NZ credit cards have APRs between 13.9% and 25.9%, with many around 19.9%.

Q3: Does this account for minimum payments?
A: No, this assumes fixed payments. Minimum payments (usually 2-3% of balance) would take much longer.

Q4: How can I pay off my card faster?
A: Increase monthly payments, reduce spending on the card, consider a balance transfer to a lower-rate card, or negotiate with your bank.

Q5: Are there fees not included in this calculation?
A: Yes, this doesn't account for annual fees, late fees, or other charges that may apply to your account.
