Credit card limit calculator for Thailand

Enter one applicant or cardholder. The limit is the lowest of what card behaviour allows, what income carries after other debts and what Thailand’s rules allow, and the page names which one sets it.

Market and caps

The Thai caps are read from the Bank of Thailand notification of 2020, which keeps the tiers in force since 1 September 2017. Check the current text before relying on them.

The interest rate changes the result only for the United Kingdom, Australia, France, Belgium and Mexico, and the repayment period only for the United Kingdom.

0 leaves this cap off.

0 means a new applicant, who gets the starting multiple instead of the behaviour rules.

The limit is ฿120,000, set by rules in Thailand (Bank of Thailand). Behaviour gives ฿150,000, income carries ฿200,000, and the market’s rules allow ฿120,000, which reflects an income cap in some markets and a repayment test in others.

High utilisation with enough statements paid in full earns the large increase.

Show formulas
Behaviour limit, New applicant = Starting income multiple × Monthly net income
Behaviour limit, Cardholder = Today’s limit × (1 + Large increase | Small increase) or × (1 − Cut after missed payments)
Affordability limit = (Income share for all debt payments × Monthly net income − Other debt payments) ÷ Card payment share of limit
Own income cap = Own income cap × Monthly net income
Market = Lowest applicable market cap
Credit limit = min(Behaviour limit, Affordability limit, Own income cap, Market), Rounded down Rounding step

The affordability limit assumes the card is fully drawn, and the behaviour rules are an example policy to edit, not a standard. Regulatory caps are summaries for this tool and are not legal advice.

Thailand credit card limit rules

The Bank of Thailand rules set a minimum monthly income of THB 15,000 and a maximum limit per issuer based on income. The page applies the relevant income cap and shows it alongside the affordability limit.

The credit card limit is the lowest of the behaviour, affordability, lender income cap and Thailand rules candidates. Which one sets the limit changes by applicant or cardholder, so use the decision table to review a case and edit the example behaviour policy.
