The question in my Quora Email Alert is: “What is the best use of a credit card you ever did?”

That’s the question I’m answering.

TY for the A2A.

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.
