Estimate what today's expenses will cost in future and what your savings will be worth, then check whether your FD or PPF return beats inflation.

Inflation results are estimates for planning and should be checked against current official rules or professional advice where applicable.
At 6% annual inflation, something costing Rs 1,00,000 today will cost about Rs 1,79,085 in ten years. Put the other way, Rs 1 lakh held as cash will then buy only what Rs 55,839 buys now. This inflation calculator runs both calculations for any amount, rate and period.
Future cost = Today's cost x (1 + inflation)^years
Use this for goals like a child's education, a wedding or a new car. It tells you the amount you will need later, not the amount you need today.
Real value = Amount / (1 + inflation)^years
This answers the opposite question. It shows what a fixed sum, like a pension or a cash balance, will be worth in future.
A 7% fixed deposit sounds fine until inflation is taken out. The real return is not simply 7 minus 6. The accurate formula is shown below.
Real return = (1 + nominal rate) / (1 + inflation) - 1
| Investment | Nominal return | Inflation | Real return |
|---|---|---|---|
| Savings account | 4% | 6% | -1.89% |
| Bank FD | 7% | 6% | 0.94% |
| PPF | 7.1% | 6% | 1.04% |
| Equity (assumed) | 12% | 6% | 5.66% |
Tax makes the FD row worse, since interest is taxed at your slab rate. PPF interest is tax-free, which is part of its appeal. A savings account at 4% steadily loses value whenever inflation runs at 6%.
Suppose a four-year engineering degree costs Rs 10 lakh today and your child starts in 15 years. At an 8% education inflation rate, that degree will cost about Rs 31.7 lakh. Saving towards Rs 10 lakh would leave you two-thirds short. That gap is exactly what this calculation is meant to expose early.
RBI targets CPI inflation of 4%, with a tolerance band of 2-6%. Actual inflation has swung well above and below that target in recent years.
Your personal inflation can differ sharply from the national figure. A family renting in a big city feels rent and school fees far more than vegetable prices. The official index basket may not match your spending at all.
Inflation also never stays constant for decades. A single average rate smooths over spikes, so read long-range results as a planning range. ToolsMate lets you rerun the inflation calculator at a higher and a lower rate to see that spread clearly.

Multiply today's cost by (1 + inflation rate) raised to the number of years. For Rs 50,000 at 6% over 5 years, the answer is about Rs 66,911. That is what you would need later to buy the same thing.
CPI inflation in India has averaged around 5% over the past decade, with sharp swings in particular years. RBI's official target is 4%, with a tolerance band of 2-6%. Use the latest MoSPI release for current figures.
CPI tracks prices consumers pay for a basket of food, housing, services and goods. WPI tracks wholesale prices of goods, mostly at the producer level. CPI is the measure RBI targets and the one relevant to household planning.
Start with your current monthly expenses and inflate them to your retirement year. Rs 50,000 a month at 6% becomes about Rs 1.6 lakh in 20 years. Your retirement corpus must support that inflated figure, not today's spending.
Simple subtraction slightly overstates it. The precise method divides (1 + nominal) by (1 + inflation) and subtracts one. At 7% nominal and 6% inflation, the real return is about 0.94%, not 1%. The gap widens at higher rates.
Yes. Enter the older amount and the average inflation rate for the period to estimate today's equivalent. For precise historic comparisons, use year-wise CPI index values rather than one average rate across the whole span.
Over long periods, Indian equities have generally beaten inflation by a clear margin, despite sharp short-term falls. Gold has also outpaced inflation across many decades, but its returns vary widely by period. Past performance never guarantees future results.
