If you have landed here, you probably already have a rough figure in your head and want to confirm it. Good instinct. Rough figures are usually off by more than people expect, and the difference compounds. Here is how the calculation really runs, and how to check yours in under a minute.

How this is worked out
Inflation reduces what your money can buy over time. This tool helps you see the future cost of a current expense.
The formula behind it:
Future Cost = Present Cost * (1 + inflation)^years
| Symbol | What it means |
|---|---|
Present Cost |
Today's Cost |
inflation |
Annual Inflation Rate |
Nothing is rounded away quietly and nothing is assumed on your behalf. If a figure appears in the result, it came from something you entered.
A worked example you can follow
₹10 Lakh today will need ~₹24 Lakh in 15 years at 6% inflation.
Change any one input and watch the result move — that sensitivity is the real lesson. It is far more useful than memorising a single outcome, because your own rate, tenure or contribution will never match the example exactly.
Using the Inflation Calculator, step by step
- Open the Inflation Calculator.
- Enter your figures. Use the ones on your statement, sanction letter or scheme document rather than a remembered number.
- Read the result card — the headline figure plus the breakdown that produced it.
- Adjust one input at a time to see what genuinely moves the outcome.
- Tap Download PDF to keep a copy of the calculation, with your inputs and assumptions printed on it.
The PDF takes a few seconds to build because it is a properly typeset report, not a screenshot. You will see a progress message while it is being prepared, and the download starts on its own.
Practical pointers
- Use 6-7% as a realistic long-term inflation rate for India.
- Inflation is an assumption based on historical data.
Common mistakes worth avoiding
- Ignoring inflation in long-term retirement planning.
