Credit card issuers allow you to convert your purchases into to equated monthly instalments (EMI). However, every purchase would not be possible to be converted. One must check whether the credit card you use has the EMI option and moreover, if the particular product you purchase can be bought in EMI.

Finally, if you are looking to pay off the amount in 5 EMIs while the credit card EMI option is available only for 10 EMIs, then it would not be a viable option as there would be more outgo on the interest payment. Hence calculate all the charges incurred in purchasing a product using credit card EMI option
