The Inflation Calculator helps you visualize how inflation erodes the value of your money and drives up the cost of living over time.

1. Future Cost Formula

To calculate what a basket of goods costing ₹X today will cost in N years:

Future Cost = Amount × (1 + Inflation Rate / 100)Years

2. Future Purchasing Power Formula

To calculate the real buying power of today's ₹X in N years:

Purchasing Power = Amount / (1 + Inflation Rate / 100)Years

Frequently Asked Questions

Inflation raises the cost of goods and services over time, which reduces the purchasing power of your money. A fixed sum of savings will buy fewer goods in the future than it does today.

At a standard 6% inflation rate, ₹1,00,000 today will have a purchasing power equivalent to about ₹55,839 in 10 years, meaning it loses nearly 44% of its value.

Future Cost shows how much money you will need in the future to buy the same basket of goods that costs ₹X today. Future Purchasing Power shows what today's amount of ₹X will be worth in terms of today's buying power in the future.
