What is the Inflation Calculator?
An inflation calculator computes the future cost of goods and services based on historical and projected inflation rates. It shows you how many rupees (or dollars) you'll need in the future to buy what costs a certain amount today, accounting for the eroding effect of inflation on currency value.
How it works
The calculator applies the inflation formula to your initial amount over a specified number of years. It multiplies your present-day amount by (1 + inflation rate) raised to the power of the number of years, revealing the inflated future value. This demonstrates how inflation compounds annually, gradually reducing purchasing power unless your savings or income keeps pace.
Future Value = Present Value × (1 + Inflation Rate)^Years
Present Value is the amount you have today, Inflation Rate is the annual percentage increase in prices (typically 4–7% in India), and Years is the time period you're calculating for. The exponent shows that inflation compounds—each year's inflation applies to the already-inflated amount.

Notes
₹1,00,000 today, 5% annual inflation, 10 years
₹1,62,889
Your ₹1,00,000 buys significantly less in 10 years; you'd need ₹1,62,889 to buy the same basket of goods.
₹50,000 today, 6% annual inflation, 20 years
₹1,60,357
Over two decades, inflation triples what you need—a stark reminder to invest and grow wealth faster than inflation.
₹5,00,000 today, 4% annual inflation, 5 years
₹6,08,326
Even moderate inflation adds over ₹1 lakh to future costs in just five years.

Tips & common mistakes
Common mistakes
Using inflation rates from other countries; India's inflation (4–7%) differs from developed nations.
Forgetting that inflation is cumulative—each year compounds on the previous, not just the original amount.
Assuming inflation will remain constant; it fluctuates based on economic conditions, fuel prices, and policy.
Ignoring your personal inflation rate, which may differ if you spend heavily on sectors with higher inflation (e.g., healthcare, education).
Tips
Use the RBI's average inflation rate (~5.5%) as a baseline for long-term Indian planning.
Run multiple scenarios (3%, 5%, 7%) to stress-test your financial plans across inflation regimes.
Pair this calculator with retirement or investment calculators to ensure your corpus grows faster than inflation.
Review inflation trends quarterly; adjust your planning if persistent inflation spikes or drops unexpectedly.
Frequently asked questions
Why does my ₹1 lakh today not equal ₹1 lakh in 10 years?
Inflation erodes purchasing power. As prices rise annually, the same amount of money buys fewer goods. With 5% inflation, ₹1 lakh becomes worth only ₹61,391 in real terms after 10 years.
What inflation rate should I use for India?
The RBI targets 4% (medium-term), but historical and projected rates typically range 4–7%. Use 5.5% as a realistic long-term average for Indian household planning.
How is this different from a loan or investment calculator?
The inflation calculator shows how much you'll need to buy the same things in the future. Investment calculators show how much your money grows; use both to ensure your returns beat inflation.
Can I use this for currencies other than rupees?
Yes, the math works for any currency. Just adjust the inflation rate to match that country's economic conditions (e.g., 2.5% for US, 3% for Europe).
Does inflation affect my savings account or FD interest?
Yes. If your FD earns 5% but inflation is 6%, your real return is negative (–1%). Your actual purchasing power shrinks despite earning interest.
How often should I recalculate?
Annually or whenever inflation rates change significantly. Quarterly reviews help you stay responsive to economic shifts and adjust savings/investment targets.
