What is the Inflation Calculator?
This inflation calculator shows what an amount costing the same today could cost after a number of years at an inflation rate you enter. It also shows what today's amount would be worth in future buying power and the per cent of purchasing power lost.
How it works
The future cost is today's amount multiplied by (1 + i)^t, where i is the yearly inflation rate as a fraction and t is the years. The buying power of today's amount in future is the amount divided by (1 + i)^t. The loss is one minus 1 / (1 + i)^t.
How to use it
- Enter an amount that you spend or hold today.
- Type the yearly inflation rate you want to assume.
- Enter the number of years.
- Read the future cost and the loss of purchasing power.
Inflation Calculator — FAQ
Which inflation rate should I use?
Use a figure you consider reasonable for planning. This tool does not supply a rate, and the real rate changes with time and with what you buy.
What does loss of purchasing power mean?
It means the same rupees buy less in future. A higher rate or a longer period increases the loss.
Does inflation affect savings and goals?
Yes. A goal that costs a certain amount today will usually cost more later, so plan targets with a future cost in mind.
