Inflation Calculator
Calculate how inflation erodes your money's purchasing power over time. Enter an amount, inflation rate, and years to get the future inflated value and real purchasing power.
About This Calculator
The Inflation Calculator helps you understand how rising prices reduce the purchasing power of your money over time. Whether you are planning for retirement, estimating future education costs, or simply curious about how inflation affects your savings, this calculator gives you both the future inflated value (what something will cost later) and the purchasing power (what your money will be worth in today's terms).
The calculator uses the standard compound inflation formula: Future Value = Present Value × (1 + Annual Inflation Rate)Years. For example, at 6% annual inflation, ₹1,00,000 today will need about ₹1,79,085 in 10 years to buy the same goods and services. The purchasing power is calculated as Present Value / (1 + Annual Inflation Rate)Years, which shows how much your current money will be worth in real terms. The yearly breakdown table and growth chart illustrate how inflation compounds over time.

Frequently Asked Questions
How does the Inflation Calculator work?
Enter the initial amount, expected annual inflation rate, and time period in years. The calculator uses the compound formula Future Value = Amount × (1 + Inflation Rate)^Years to compute the inflated value and purchasing power loss.
What is the formula for calculating inflation-adjusted value?
The future value after inflation is calculated as FV = PV × (1 + r)^n, where PV is the present amount, r is the annual inflation rate, and n is the number of years. The purchasing power is PV / (1 + r)^n, showing what your money will be worth in today's terms.
How does inflation affect purchasing power in India?
In India, the average inflation rate has ranged between 4-6% in recent years. At 6% inflation, an item worth ₹1,00,000 today will cost approximately ₹1,79,085 in 10 years, while the purchasing power of that ₹1,00,000 will drop to about ₹55,839 in real terms.
How does inflation affect purchasing power in the US?
In the US, the Federal Reserve targets a 2% annual inflation rate. At 3% inflation, something costing $10,000 today will cost about $13,439 in 10 years, and the purchasing power of $10,000 will decline to roughly $7,441 in today's dollars.
How does inflation affect purchasing power in the UK?
In the UK, the Bank of England targets a 2% CPI inflation rate. At 2.5% inflation, an item worth £8,000 today will cost about £10,240 in 10 years, and the real purchasing power of that £8,000 will fall to approximately £6,250.
Is this calculator free?
Yes, it is completely free to use with no registration required. You can also share your calculation by copying the URL, which saves all your input values.
What is the difference between nominal value and real value?
Nominal value is the face value of money without adjusting for inflation. Real value (or purchasing power) adjusts the nominal value for inflation to show what the money is actually worth in terms of today's goods and services. The calculator shows both.
How can I protect my savings from inflation?
To protect savings from inflation, consider investing in assets that historically outpace inflation such as equities, real estate, inflation-indexed bonds (like I-Bonds in US or inflation-linked bonds in India/UK), and diversified mutual funds. Keeping large sums in cash savings accounts often leads to purchasing power loss over time.
