Using my credit card to withdraw cash and open my PPF account is perhaps the best use of a credit card I’ve ever done.

The tax year end was fast approaching. I wanted to open a Public Provident Fund account (India’s equivalent of pension) to save income tax. I didn’t have the money with which to open the PPF account. I took a cash advance on my credit card, used that money to fund the PPF account opening. I paid the outstanding in full the next month. Of course, I incurred exorbitant interest charges.

But the amount of tax I saved was 5X the amount of interest I paid.

I doubt if I’ve ever achieved such a high return in one month in any other pursuit.

Ergo, this must be the best use of credit card I’ve ever done.
