In India, a balance transfer is only advantageous if you’re 100% sure you can pay it off during that 3–6 month promotional window. If not, you’re actually better off with a short-term personal loan at 10–14%. It sounds higher upfront, but it usually saves you more in the long run. Always look at the APR; that's the real number that matters.
