Inflation quietly eats away the value of money. This calculator shows what an amount of money today will cost in the future at a given inflation rate, and what today's amount is worth in real (inflation-adjusted) terms going forward.
India CPI average: 6-7%
Future cost
₹3,20,714
Same basket in 20 yr
Today's purchasing power
₹31,180
What ₹1,00,000 buys in 20 yr
Value erosion
68.8%
Lost to inflation
In simple terms
₹1,00,000 today will need to grow to ₹3,20,714 in 20 years just to buy the same basket of goods at 6% inflation. To beat inflation, your investments need to return more than 6% per year after tax.
India's CPI is a national average. Your personal inflation may be higher (medical, education) or lower (rural / non-discretionary). Plan with a buffer.

Inflation is the silent thief in every long-term financial plan. The salary that bought a comfortable middle-class lifestyle for your parents barely covers basics today, and the corpus that retires you handsomely in 2026 may struggle to cover groceries by 2046. Yet most retirement plans, savings goals and 'how much do I need' calculations are done in today's rupees as if inflation didn't exist. This calculator translates between today's rupees and future rupees so you can plan in real, comparable terms.
Long-term Indian CPI inflation has averaged 6-7% per year. That sounds modest until you compound it: ₹1,000 in 1990 buys what ₹100 bought back then; ₹50,000 a month today buys what ₹13,000 bought 25 years ago. Different categories inflate at different rates - education at 9-11%, medical care at 10-13%, urban housing at 7-9%, food at 5-8%. Use the relevant category's inflation rate, not the headline number, for category-specific planning.
Enter the amount in today's rupees.
Set the expected annual inflation rate (India: 6-7% historical average).
Pick the number of years.
See the future cost (what the same goods will cost in N years) and the purchasing power (how much today's amount will actually buy in N years).
Inflation compounds, just like interest. At 6% annual inflation, prices double roughly every 12 years. The calculator runs the basic compounding formula in two directions - forwards to show the future cost of today's basket, and backwards to show the purchasing power erosion.
FutureCost = Amount × (1 + i)^t ; PurchasingPower = Amount / (1 + i)^t
The formula uses the standard compound-growth formula. Future cost of an item priced ₹X today, at inflation rate i for t years = X × (1+i)^t. Going the other way, an amount ₹Y t years from now is worth Y / (1+i)^t in today's purchasing power. The math is symmetric and exact - what's harder is picking the right inflation rate, since headline numbers, RBI targets and your personal experience often differ by 2-3 percentage points.
India publishes two main inflation indices: the Consumer Price Index (CPI), which the RBI uses for its 4% target, and the Wholesale Price Index (WPI), used for inflation-indexed bonds and some industrial contracts. CPI is the relevant number for personal financial planning. CPI breaks down further into Combined (national), Urban, Rural and category-wise (food, fuel, housing, etc.) - use the most relevant category for your specific goal.
The RBI inflation target is 4% with a ±2% band, and the central bank uses repo-rate adjustments to anchor expectations. In practice, periods of 6-7% inflation have been more common than periods at the 4% target. For long-term planning (retirement, education), assume 6% as a base case and 8% as a stress-test case.
Future monthly need: 50,000 × 1.06^25 = ₹2,14,594. To fund this for 25 years post-retirement at the same standard of living, you'd need a corpus of roughly ₹4-5 crore at retirement (at a 5% safe withdrawal rate adjusted for partial inflation indexing).
Education inflation 9%. Future cost: 20,00,000 × 1.09^18 = ₹94,40,000. The typical SIP needed to get there at 12% expected return is roughly ₹16,000/month - and the rule of thumb is that a 5% step-up SIP roughly halves that monthly requirement.
Headline CPI inflation has averaged 6-7% over the past decade, with periods spiking to 10%+ and dipping to 3-4%. The RBI targets 4% with a ±2% band. Use 6-7% for long-term planning.
If you need ₹50,000 a month today and retire in 25 years at 6% inflation, you will need over ₹2.1 lakh a month at retirement to maintain the same lifestyle. Ignoring inflation is the #1 reason people under-save for retirement.
Yes - much higher. Medical costs in India have inflated at 10-12% per year. Plan healthcare expenses with this higher rate.
Real return = nominal return − inflation. If your FD pays 7% but inflation is 6%, your real return is just 1%. Equity at 12% gives a real return of ~6%, which is why long-term wealth builds in equity.
Hold investments whose long-term return exceeds inflation by a clear margin. In India that historically means equity (mutual funds, index funds), real estate (over 7+ years), and gold (as a hedge). Pure savings accounts and most FDs barely keep pace post-tax.
No. Urban inflation is typically a percentage point higher than rural. State-level inflation varies based on the local consumption basket. The official CPI is a national weighted average - regional households may experience higher or lower inflation.
Indian financial products - home loans, fixed deposits, mutual funds, NPS, insurance - each carry their own quirks: monthly reducing balance vs flat-rate interest, quarterly vs monthly compounding, indexation on capital gains, the choice between the old and new tax regime. We design every finance calculator to use the formula that an Indian bank, AMC, or insurer would actually use, and to surface the assumptions in plain English so you can audit the result against your own statement.
Use this calculator alongside the EMI, SIP and inflation calculators to plan your money holistically. A standalone EMI number means little until you compare it with your in-hand salary, your existing debt-to-income ratio, and the impact of inflation on the real cost of the loan. The related-tool grid below makes it one click to chain these analyses together.
The Inflation Calculator is part of the Finance suite on Online Calculator Tools, alongside 6 related calculators. All tools share the same UI patterns, the same privacy-first rendering (nothing is sent to a server), and the same commitment to showing the formula and assumptions behind every result.
