Inflation Calculator – Calculate Purchasing Power & Future Value
India average CPI inflation ~6%. You can edit this value.
What is Inflation?
Inflation is the gradual rise in the price of goods and services over time. When inflation is 6% per year, something that costs ₹1,00,000 today will cost approximately ₹1,06,000 next year. Over long periods, even moderate inflation significantly erodes the purchasing power of money — making an Inflation Calculator an essential financial planning tool.
Inflation Formula Used
FV = PV × (1 + rate/100)^years
FV = Future Value | PV = Present Value | rate = annual inflation % | years = To Year - From Year
Worked example:
- Amount: ₹1,00,000
- From: 2000 To: 2025 (25 years)
- Inflation Rate: 6%
FV = 1,00,000 × (1.06)^25
Future Value ≈ ₹4,29,187 | Purchasing Power Loss ≈ ₹3,29,187
Inflation in India
RBI's Inflation Target
The Reserve Bank of India (RBI) targets a CPI inflation rate of 4% with a tolerance band of ±2% (i.e., 2%–6%). When inflation rises above 6%, the RBI typically raises interest rates to cool demand and bring prices down.
Historical Average
India's average CPI inflation from 2000 to 2024 has been approximately 6–7% per year. Some years saw spikes above 10% (especially 2009–2014), while recent years (2021–2024) have been closer to 5–7%. The default rate of 6% in this calculator represents a conservative long-term average.
Why Inflation Matters for Savings
If your savings earn a return lower than the inflation rate, your money loses real value each year. This is why financial planners recommend equity investments for long-term goals — historically, equities have outpaced inflation over 10+ year periods, while bank savings accounts and low-yield FDs often fall short.
Frequently Asked Questions
What is inflation?
Inflation is the rate at which the general price level of goods and services rises over time, eroding purchasing power. At 6% inflation, something costing ₹100 today will cost ₹106 next year.
What is the average inflation rate in India?
India's average CPI inflation has been approximately 5–7% per year over the past two decades. The RBI targets 4% ±2%. The default rate in this calculator is 6%, representing a typical long-term average.
How is future value calculated with inflation?
FV = PV × (1 + rate/100)^years. For ₹1,00,000 at 6% for 10 years: FV = 1,00,000 × (1.06)^10 ≈ ₹1,79,085.
What is purchasing power loss?
Purchasing power loss is the additional amount needed in the future to buy what a given amount buys today. It equals Future Value minus Present Value. Higher inflation and longer time periods result in larger purchasing power losses.
How does inflation affect savings and investments?
If your investment return is lower than the inflation rate, your real return is negative — your money buys less each year even as the rupee amount grows. Always target returns that beat inflation to preserve and grow real wealth.
Can I use a custom inflation rate?
Yes. The inflation rate field in this calculator is editable. You can enter the actual historical CPI rate for a specific period, or use a projected rate for future planning.
