How to use Inflation Calculator
Inflation raises the cost of a similar basket of goods over time. This calculator repeats a rate you choose to estimate the future price of a purchase and the future purchasing power of a fixed cash amount.
The rate is a scenario rather than a forecast or a live inflation figure. Personal costs such as education, rent and healthcare may grow differently from an overall consumer price index. Try more than one assumption for a long-term plan.
The formula
A worked example
Cost or amount today (₹): 100000 · Assumed annual inflation (%): 6 · Duration (years): 10
Future cost of the same purchase: ₹1,79,084.77
Assumes the same annual inflation rate throughout. This is a scenario, not an inflation forecast.
Questions about this calculation
Does this use India’s current inflation rate?
No. You enter the rate; the calculator does not fetch official statistics.
Why is purchasing power lower?
A fixed cash amount buys less when prices rise. The calculator divides it by the compounded increase in prices.
