Typical Singapore credit card interest rates – for balances not fully repaid by the monthly due date – fall into the range 15%-28% p.a. At the higher end, the rate may be well in excess of the interest rate you are accustomed to in your own country, so bear this in mind when planning your credit card spending and repayments. It’s also possible that credit card issuers may impose a higher interest rate on foreigners simply because they are considered a more risky proposition than locals.
