Singapore Credit Card Calculators 2026

Most Singapore credit cards charge 25%–27% per annum on revolving balances, calculated daily from the transaction date once the grace period is lost. This is among the highest consumer borrowing rates available.

It depends entirely on your spending pattern and travel habits. Cashback cards suit irregular spenders wanting simplicity, while miles cards reward consistent spenders with a clear redemption plan for flights or upgrades. Use the Cashback vs Miles ROI Calculator with your actual monthly spend to compare.

You lose your interest-free grace period and interest accrues on the full outstanding balance at the card’s APR (typically 25%–27%). Paying only the minimum (1%–3% of balance) can take well over a decade to clear and cost multiples of the original balance in interest.

Beyond the prevailing exchange rate, Singapore banks typically add a 3.25% foreign transaction mark-up. On a S$3,000 overseas trip, this alone adds roughly S$97 in fees beyond the base exchange rate.

Not always. Many “0% interest” instalment plans charge a separate processing or administrative fee, which creates a real effective interest rate even though no interest is technically charged. Always check the total repayment amount against the cash price.

Key factors include your credit utilisation ratio (balance versus credit limit), payment history, number of recent applications, and length of credit history. Keeping utilisation under 30% and always paying on time are the most impactful habits.
