After Tax And Inflation, Safe Can Go Backwards

25 June 2026.2 min read.By Tanmay Kurtkoti

An uncle cornered me at a wedding last month to tell me his fixed deposit had doubled his money in ten years. Proud of it. And he was right, sort of. The rupees did roughly double. What I did not have the heart to say over the buffet is that the part that matters, what those rupees can actually buy, barely moved.

Here is the part the statement never shows you.

A 7 percent FD does not pay a 7 percent return. If you are in the top tax slab, 30 percent of that interest goes to tax every year, so you are really earning 4.9. Then inflation running near 5 percent quietly takes the rest. What is left, the real return, is roughly zero. For a top-slab saver it actually tips slightly negative.

The cruel part is what it looks like. The same 7 percent FD pays three different people three different real returns. A 5 percent slab saver keeps about +1.65 percent in real terms. A 20 percent slab saver keeps +0.60. A 30 percent slab saver lands at minus 0.10. Same poster rate. Your tax slab decides whether safe is even keeping up with prices.

Put numbers on it. Ten lakh parked for ten years at the top slab grows to about 19.67 lakh on the statement. Feels like it doubled. Strip the tax and the inflation and the purchasing power is around 9.9 lakh. Less than the lakh you started with, in real terms.

This is not an argument against fixed deposits. It is an argument against using one for the wrong job. An FD is a parking spot. Perfect for your emergency fund and money you need in a year or two, where not falling is the whole point. It is a poor engine for a twenty-year goal, where erosion compounds against you the same way growth would have compounded for you.

The honest version: an FD never shows you a loss. That is exactly why it is the easiest place to lose money slowly.
