What is Inflation and How Does it hurt Savings?

Inflation is the rise in the general level of prices over time, which means each rupee buys a little less every year. It hurts savings because money that earns less than the inflation rate, after tax, loses buying power even while its balance grows. To protect your savings, compare every return you earn with inflation, not just with zero.

In India, inflation is measured mainly by the Consumer Price Index (CPI), which tracks the prices of a basket of goods and services that households buy: food, fuel, housing, clothing, healthcare, education, transport and more.

What is India's inflation rate now?

Retail inflation, measured by the CPI, was 5.54% in September 2026 compared with a year earlier. Food prices rose faster, at 7.74%. Rural inflation was 6.08% and urban inflation 4.88%.

The RBI's job is to keep CPI inflation at 4%, within a band of 2% to 6%, under a target the government has set for April 2026 to March 2031. When inflation runs above target, the RBI tends to raise interest rates, as explained in the lesson on interest rates and the repo rate.

As of October 2026. These are the CPI figures for September 2026 (base year 2024 = 100), released on 12 October 2026 by the Ministry of Statistics and Programme Implementation. A new figure is released around the 12th of every month. Check the latest on the MoSPI website and the inflation target on the RBI website.

How does inflation shrink the value of money?

Inflation works like compounding in reverse. Each year's price rise is added on top of the last, so the damage grows over time. Here is what ₹1,00,000 kept as cash would buy, in today's money, at a hypothetical 6% inflation:

A quick way to estimate this is the rule of 72: divide 72 by the inflation rate to find roughly how many years it takes for prices to double. At 6%, prices double in about 12 years. At 8%, in about 9.

A worked example: the birthday party

Priya (a hypothetical example) plans her daughter's first birthday. The organiser quotes ₹1,00,000 today but can't promise that price in a year. Priya puts ₹1,00,000 in a one-year deposit at a hypothetical 7%.

• After a year she has ₹1,07,000 before tax. In the 30% tax bracket, the ₹7,000 interest becomes ₹4,900 after tax, leaving ₹1,04,900.
• Over the same year, the organiser's costs rise 6%, so the party now costs ₹1,06,000.
• Priya is ₹1,100 short, even though her money "grew".

If prices keep rising at 6% a year, the same party would cost about ₹1,79,000 by her daughter's 10th birthday. Planning with today's prices will always leave you short.

What is the real rate of return?

The real return is what you earn after inflation: how much more your money can actually buy. To work it out properly:

Real return = (1 + return after tax) ÷ (1 + inflation) − 1

A quick approximation is simply return after tax − inflation. Using the September 2026 inflation rate of 5.54% and a hypothetical 7% fixed deposit:

Your tax rate on the interest	Return after tax	Real return
No tax	7.00%	+1.38%
5%	6.65%	+1.05%
20%	5.60%	+0.06%
30%	4.90%	−0.61%

Hypothetical deposit rate; tax rates shown before cess and surcharge. Inflation varies from year to year.

For someone in the 30% bracket, the deposit loses buying power. The balance goes up, but what it can buy goes down. The next lesson, on why fixed deposits alone are not enough, takes this further.

Is your own inflation the same as the CPI?

Usually not. The CPI is an average across millions of households. Your personal inflation depends on what you spend on:

• Education and healthcare costs often rise faster than the CPI. A family saving for a child's college or caring for elderly parents may face higher inflation than the headline rate.
• Food has a large weight in poorer households, so food price spikes hit them harder.
• Rent can jump sharply at renewal in fast-growing cities.

When planning a goal far in the future, use an inflation rate for that type of expense, not just the headline CPI. Many planners use a higher rate, such as 8% to 10%, for education costs, but check recent fee increases for the courses you have in mind.

How does inflation affect different investments?

Investment	How inflation tends to affect it
Cash and savings accounts	Hit hardest. The return is usually below inflation, so buying power falls.
Fixed deposits and bonds	The rate is locked in. If inflation rises after you invest, your real return falls. Bond prices tend to fall when interest rates rise to fight inflation.
Shares	Over long periods, company profits and share prices have tended to grow faster than inflation, because companies can raise their prices. In the short term, high inflation and rising rates often hurt share prices.
Gold	Has often held its value over long periods and during inflation scares, but its price can stay flat or fall for years.
Property	Values and rents often rise with inflation over time, but property is costly to buy and sell, and hard to sell quickly.

No single asset protects you from inflation every year. That is one reason later lessons recommend spreading money across different assets.

How can you protect your savings from inflation?

1. Keep only what you need in cash: your emergency fund and near-term spending. Idle money above that loses value every year.
2. Think in real returns: when comparing options, subtract tax and inflation before celebrating a headline rate.
3. Plan goals in future prices: inflate today's cost to the year you need the money, using the time value of money from the earlier lesson.
4. Give long-term money growth assets: for goals many years away, money needs a chance to beat inflation, which usually means some exposure to shares. The investing modules explain how, and the risks involved.
5. Raise your savings with your income: inflation lifts your expenses every year, so your saving amount should rise too.

1. At about 6% inflation a year, roughly how long does it take for prices to double?

Choose one answer.

6 years 12 years 20 years 72 years

Show answer

Answer: 12 years. The rule of 72: 72 ÷ 6 = about 12 years.

2. An FD pays 7%. You pay 30% tax on the interest, and inflation is 5.54%. What is your real return, roughly?

Choose one answer.

About +7% About +1.5% About −0.6% About −5.5%

Show answer

Answer: About −0.6%. After tax the return is 4.9%. Real return = 1.049 ÷ 1.0554 − 1 ≈ −0.6%, so the deposit loses buying power.

3. Your personal inflation rate can be higher than the official CPI figure.

True or false?

True False

Show answer

Answer: True. The CPI is an average. If much of your spending goes on things whose prices rise faster, such as education or healthcare, your own inflation can be higher.
