Question: My statement only shows the minimum amount due and hides how long repayment will take. Is that acceptable?
Answer: No. RBI requires issuers to explain the implications of paying only the minimum amount due and to prominently warn that paying only the minimum can stretch repayment over months or years with compounded interest.
