📘 About the Inflation Calculator

Inflation quietly raises prices year after year, so the same money buys less over time. This calculator shows what a cost you face today, such as college fees or a wedding, is likely to be in the future.

Enter today's cost, an expected yearly inflation rate and the number of years to see the future cost and the increase.

🧮 Formula

Future cost
Future cost = Cost today × (1 + r)ᵗ
Increase
Increase = Future cost − Cost today

Where

  • r = annual inflation rate ÷ 100
  • t = number of years

❓ Frequently asked questions

Which inflation rate should I use?

For general expenses in India, 5–7% is a common assumption. Education and healthcare costs often rise faster, so use 8–10% for those.

How do I use this for goals?

Compute the future cost of your goal, then work out the monthly investment needed to reach it with a SIP or RD.

How fast does money lose value?

At 6% inflation, prices double in about 12 years. That is the Rule of 72: 72 ÷ 6 = 12.

What will ₹1 lakh be worth in 10 years?

At 6% inflation, ₹1 lakh will buy what about ₹55,800 buys today; something costing ₹1 lakh now will cost about ₹1.79 lakh.
