About the Inflation Calculator
Inflation is the silent tax that erodes your money's purchasing power every year. A product that costs ₹100 today costs ₹321 in 20 years at 6% inflation. India's long-run CPI inflation has averaged ~6.5% over the last 20 years, with notable spikes (2009–2013 averaged 9.5%) and quieter periods (2018–2019 around 4%). RBI's mandate is to keep CPI in a 2–6% band, but supply shocks (oil, food, currency) regularly push it past 6% for months at a time.
This calculator projects how much an expense will grow in nominal rupees. The reverse — today's purchasing power of a future amount — is also shown. Use it before any major financial decision: how much will your child's college cost in 15 years? How much will your retirement lifestyle cost in 25 years? How much will a family car cost in 5 years? The numbers are usually 30–80% larger than people instinctively assume.
Rule of thumb: at 6% inflation, your money's purchasing power halves every ~12 years. That's the reason idle cash in a savings account paying 3% is slowly bleeding value at ~3% per year in real terms. Even an FD at 7% is barely keeping pace post-tax for a 30%-bracket taxpayer (post-tax ~4.9%, vs 6% inflation = −1.1% real return). The mathematical reason equity is essential for long-term wealth: it's the only mainstream Indian asset class that has consistently delivered 5%+ real returns over 15+ year windows.
Different inflation rates apply to different categories — and using a blended 6% can mislead you on specific goals. Education inflation in India has averaged 9–11% (private school fees, IIT/IIM/medical college costs). Healthcare inflation 12–14% (private hospital procedures, medicines). Real estate 5–7% nationally, but 8–12% in tier-1 cities pre-2014, near-flat 2014–2021, and rising again 2022 onwards. Lifestyle goods (electronics, cars) 3–5%. Use category-specific rates when planning category-specific goals.
Behavioral implication: most retail investors fail at long-term wealth-building not because they make bad investment choices, but because they underestimate the corpus they actually need. A retirement plan built on 'I'll need ₹50,000/month' falls short if you don't ask 'in what year's rupees?' The same ₹50K monthly expense becomes ₹2.87 lakh/month in 30 years at 6% inflation. Build all goal-based planning, retirement corpus calculations, and emergency fund targets in inflation-adjusted future-value terms — not today's rupees.
