How inflation eats your savings

The tax nobody votes on

Inflation is the rise in prices across the economy, and it works like a tax on money that sits still. If prices rise 5% this year, the ₹1,00,000 in your savings account buys what ₹95,000 or so bought last year. The balance didn't change, so it doesn't feel like a loss. It is one.

The latest reading: retail inflation measured by the Consumer Price Index (CPI) was 4.82% in August 2026, up from 4.45% in July, according to provisional figures from MoSPI. Food inflation was higher, at 5.95%. RBI's target is 4%, within a tolerance band of 2% to 6%, so August sits inside the band but above the middle of it.

What it does over time

The damage is small in a year and large over a working life:

Purchasing power in today's rupees. Rounded.

At 6%, prices roughly double every 12 years. Someone who is 30 today and spends ₹50,000 a month will need around ₹2.9 lakh a month at 60 to live the same way, if inflation averages 6%. That is why a retirement number that looks huge in today's money often isn't. Try your own figures in the inflation calculator.

Your own inflation can also be higher than the headline. CPI is an average across a basket of goods. School fees, private healthcare, rent in large cities and eating out have tended to rise faster than the basket. Our guide to inflation and your savings covers how to estimate a personal rate.

Nominal return minus tax minus inflation

What matters is the real return: what you earn after tax, less inflation. Here is how common places to park money look against August's 4.82%, using one-year returns to 1 October 2026 for the median Direct, Growth fund in each category, and an investor in the 30% slab:

Fund returns: WealthTicker, from AMFI NAV history. Tax ignores surcharge and cess. Debt fund gains are taxed at slab rate regardless of holding period for units bought since April 2023.

The pattern is plain. After tax, most "safe" options at best tread water against inflation. That's fine for an emergency fund or money needed within a year or two, where safety matters more than return. It is a slow leak for money meant for a goal ten years away.

Arbitrage funds are taxed as equity funds, so a holding of more than a year is taxed at 12.5% on gains above ₹1.25 lakh a year, which improves their after-tax return for people in high slabs. Our liquid fund returns post and FD vs debt fund calculator cover the comparison in more detail.

What has kept ahead

Over long periods, assets whose value is tied to growth in the economy or to scarcity have tended to beat inflation, at the price of swinging around a lot more. Ten-year and one-year medians to 1 October 2026, Direct, Growth:

Large-cap funds lost money over the last year and still compounded at more than twice August's inflation rate over ten. Gold funds rose 24.20% over the year; across 25 gold fund-of-funds the median five-year return was 24.70% a year, an unusually strong stretch for an asset that has also had flat years. The guide on gold funds and ETFs covers when gold has helped and when it hasn't.

None of these is a cure on its own. Equity can lose a third of its value in a bad year; gold can go sideways for years. The point is the mix: money that must not fall in a given year stays in debt and cash, and money for goals five or more years away goes where it has a chance of beating inflation.

Simple defences

1. Name the job of each rupee. Emergency fund and near-term spending in a bank or liquid fund; long-term goals in a mix that includes equity.
2. Plan with an inflation number, not today's prices. Use 6% as a general working figure, and more for education and healthcare goals.
3. Raise your SIP every year. A SIP fixed at ₹10,000 buys less each year. A step-up of even 5-10% a year keeps the contribution's real value from shrinking.
4. Count tax. A pre-tax return that beats inflation can lose to it after tax.
5. Review once a year. If your goal amount is still in today's rupees, it is too small.
