Credit card limit for individuals in Singapore
" Depending on your age, your total credit limit (across all credit cards) must be within the following boundaries."
"Up to 55 Years Old
Your credit limit is determined by your annual income (can be non-employment income, e.g. rental income). If your annual income is S$30,000 or below, your credit limit is capped at 2X your monthly income. If you earn S$30,000 to S$120,000 a year, your credit limit is up to 4X your monthly income. There is no regulation on your credit limit if you earn S$120,000 or more a year."
"Above 55 Years Old
Income requirements are lower for those above 55, but you need have at least S$750,000 to S$2m in net personal assets (e.g. property, shares). Your credit limit is based on your annual income as well. For those earning up to S$15,000, your credit limit is up to S$2,500 only. If earning S$15,000 to S$30,000, your credit limit is 2X your monthly income. Only if you are earning S$30,000 to S$120,000, will you get 4X your monthly income as the credit limit."
