Inflation Calculator

This inflation calculator shows two things at once: what something costing a given amount today will cost in the future, and what that same amount of money will actually be worth (in today's purchasing power) after inflation erodes it. Enter an amount, an annual inflation rate, and a number of years to see both sides of the same coin — useful for planning retirement income, education costs, or simply understanding why 'keeping cash under the mattress' quietly loses money every year.

₹10,00,000

A cost, price or amount of money in today's terms — a salary, an expense, or a sum you are planning to save or spend.

6.00%

Long-run average inflation in India has been roughly 5–6%. Use a higher figure to stress-test worst-case planning.

20 yrs

How far into the future you are projecting — for a retirement or education plan, this is often 10–30 years.

₹32,07,135

What today's amount will cost you to buy later — e.g. ₹10,00,000 of spending today costs about ₹32,07,135 in 20 years at 6% inflation.

What today's amount will be worth then₹3,11,805

The real purchasing power of a fixed sum after inflation — e.g. a static ₹10,00,000 will only buy what ₹3,11,805 buys today, 20 years from now.

Amount today₹10,00,000

The starting figure you entered, shown for comparison against both projections above.

Frequently asked questions

How do I calculate the future cost of something due to inflation?+

Multiply today's cost by (1 + inflation rate)ⁿ, where n is the number of years. ₹10,00,000 today at 6% inflation for 20 years will cost about ₹32,07,135 in the future — use the calculator above for any amount, rate or period.

What inflation rate should I use for retirement planning?+

Most planners use 5–6% as a long-run baseline for India, then stress-test with a higher rate (e.g. +2 points) to check the plan still works if inflation runs hotter than expected.

How much does inflation reduce the value of my savings?+

At 6% inflation, money loses close to 70% of its real purchasing power in 20 years, and around 44% in 10 years. Compare this against your savings account's actual interest rate — if the rate is lower than inflation, your balance is shrinking in real terms even as the number on the statement rises.

Why is inflation compared to compound interest?+

Both use the exact same exponential formula — a fixed percentage applied repeatedly, year after year. Compound interest grows your money; inflation shrinks what that money can buy. Treating inflation as 'negative compound interest' makes its long-run impact far more intuitive.

How does inflation affect my salary?+

If your salary rises slower than inflation, its real value falls even as the number grows — a 3% raise during 5% inflation is a 2% real pay cut. Compare your annual raise against the inflation rate for your country, not against 0%, to judge whether you are actually getting ahead.
