Inflation Calculator
See how inflation erodes the value of money in India. Free inflation calculator with future cost, present day worth and total erosion over any period.
Inflation is the steady increase in the cost of goods and services over time. In India, headline consumer inflation has averaged roughly 6 percent over the last two decades, with healthcare and education climbing faster. The inflation calculator on this page tells you how much a current expense will cost in any future year, and how much purchasing power a future amount will hold in today's rupees. Both directions matter for retirement, education and lifestyle planning.
Inputs
Why use the Inflation Calculator
Most people understate inflation because they think in nominal rupees. A retirement plan that aims for ₹1 crore feels safe today. In 25 years at 6 percent inflation, ₹1 crore has the purchasing power of roughly ₹23 lakh today. The same lifestyle that costs ₹50,000 a month today will cost more than ₹2 lakh a month in 25 years. The inflation calculator turns these abstract numbers into concrete projections so you can size your savings to a future cost rather than a present one.
Benefits at a glance
Compute the future cost of any expense
Enter what something costs today, set inflation and the number of years, and see what it will cost in the future. Useful for planning a child's education, a house purchase or a retirement budget.
See the present day worth of a future amount
The same calculator runs the inverse. If your investment will mature to ₹1 crore in 20 years, what is that worth in today's purchasing power. The answer is usually a sobering reduction.
Stress test long horizon plans
Try the same plan at 6 percent and at 8 percent inflation. The corpus required to fund retirement at the higher inflation rate is often double. That gap is the planning risk you are taking.
Visualise the erosion curve
The chart shows the future cost of the same basket of goods year by year. The curve is steeper than most people expect, particularly past the 15 year mark.
How to use the Inflation Calculator
- 1
Enter the amount today
What an expense, a goal or a future amount is in today's rupees. ₹50,000 monthly expenses, ₹1 crore retirement target, ₹25 lakh for a child's college, anything that has a current price tag.
- 2
Set the expected inflation rate
Six percent matches India's long run consumer inflation average. Use seven to eight percent for healthcare and education heavy goals. Use four to five percent for commodity heavy expenses.
- 3
Choose the number of years
Twenty five years for a retirement target. Fifteen to eighteen years for a child's higher education. Ten years for a house down payment. The longer the horizon, the larger the inflation impact.
- 4
Read both numbers
The future cost is what you will need to pay then. The present day worth is what a future amount is worth today. Use whichever frame fits your planning question.
Frequently asked questions
What inflation rate should I use for India?
Headline Consumer Price Index (CPI) inflation in India has averaged roughly 6 percent over the last 20 years and the RBI targets 4 percent with a 2 percent band. For long term financial planning, 6 percent is a reasonable default. For specific high inflation categories like healthcare (often 8 percent) and private education (often 10 percent), use the category specific rate.
Why does inflation matter so much for retirement planning?
Retirement is typically a 25 to 35 year horizon. At 6 percent inflation, expenses roughly double every 12 years. A monthly budget of ₹50,000 today becomes ₹1 lakh in 12 years, ₹2 lakh in 24 years and ₹4 lakh in 36 years. A retirement corpus that ignores this is dramatically underfunded by the time the second decade of retirement arrives.
How is inflation different from interest rates?
Interest rates are the price of money set by lenders. Inflation is the rate at which goods and services become more expensive. The difference between the two is the real return. If your fixed deposit pays 6.5 percent and inflation is 6 percent, your real return is only 0.5 percent. Real returns are what matter for purchasing power.
What is the rule of 72 for inflation?
The rule of 72 is a quick mental approximation. Divide 72 by the inflation rate to get the number of years for prices to double. At 6 percent inflation, prices double every 12 years. At 8 percent, every 9 years. The calculator gives the exact answer but the rule of 72 is useful for back of the envelope planning.
Should I use inflation in my SIP or goal calculations?
Yes, always for long term goals. The goal SIP calculator on this site has an inflation field for exactly this reason. A retirement target of ₹1 crore today is a target of roughly ₹3.2 crore in 20 years. Plan for the inflated number, not the present day number.
Does inflation apply equally to every asset?
No. Equities historically beat inflation by roughly 5 percent per year over long periods. Real estate roughly tracks inflation. Gold roughly tracks inflation over decades but lags or leads in shorter periods. Fixed deposits often barely beat inflation post tax. The asset mix you choose determines whether your wealth grows in real terms or just in nominal terms.
Has Indian inflation been higher or lower than 6 percent recently?
It has been around the 5 to 6 percent range in recent years, with periods of 7 percent or higher in 2022 to 2023 driven by food and fuel. The RBI has kept its formal target at 4 percent. For very long horizon planning (more than 15 years), 6 percent remains a defensible default.
Final word
Inflation is the silent tax on future plans. Use the calculator before setting any long term financial goal, and rerun it whenever you assume that today's prices will hold tomorrow. If you can keep your real returns positive, time is your friend. If you cannot, time becomes the slowest and most painful way to lose purchasing power. The maths shown here is a useful corrective the moment a plan starts to feel safer than it should.
