Inflation Calculator
Inflation is the silent force that quietly shrinks the value of your money every year — what ₹100 buys today will buy noticeably less a decade from now. Understanding this is essential for any long-term financial plan, from retirement to your child’s education. This inflation calculator makes the effect concrete. Enter an amount, an expected inflation rate, and a number of years, and it shows what that sum will be worth in the future and how much you would need then to maintain the same purchasing power. It is a sobering but useful reminder that money left idle loses value, and that your investments must earn more than the inflation rate just to stand still in real terms.
India's long-term average CPI inflation is roughly 6%.

About the Inflation Calculator
An inflation calculator estimates how the purchasing power of money changes over time at a given inflation rate. It shows both the future cost of today’s expenses and the shrinking real value of a fixed sum of money.
Why it is useful
Planning in today’s rupees underestimates future needs. This tool helps you set inflation-adjusted goals, judge whether a savings product genuinely grows your wealth, and appreciate why holding cash for the long term steadily erodes its value.
How the calculation works
The future cost of an expense is FV = PV × (1 + inflation)^n, where PV is today’s amount and n is the number of years. To find the future purchasing power of money held idle, the calculator divides instead: real value = amount ÷ (1 + inflation)^n.
Key inputs explained
- Current amount: The expense or sum of money in today’s rupees.
- Inflation rate: The expected average annual inflation rate.
- Number of years: How far into the future you want to look.
Example calculation
Inputs
- Current expense
- ₹50,000/month
- Inflation rate
- 6% p.a.
- Years
- 15
Calculation breakdown
- Inflation factor
- (1.06)^15 ≈ 2.397
- Future cost
- 50,000 × 2.397
- Increase
- ₹1,19,828 − ₹50,000
The same lifestyle that costs ₹50,000 a month today will cost nearly ₹1.2 lakh a month in 15 years at 6% inflation — which is why retirement and goal planning must be inflation-adjusted.
Benefits
- Reveals the real future cost of your goals.
- Helps set inflation-adjusted savings targets.
- Shows why investments must beat inflation.
Limitations
- Assumes a constant inflation rate, which varies in practice.
- Personal inflation can differ from the headline CPI figure.
- Does not predict actual future prices, only projects a rate.
Tips
- Always plan long-term goals in inflation-adjusted rupees.
- Target a “real” return — your return minus inflation — above zero.
- Use a slightly higher rate for education and healthcare, which inflate faster.
