Inflation Impact Calculator
India's headline CPI is 6%, but your personal inflation is probably higher. Healthcare runs at 10–12%, education at 10–11%. Enter your spending mix and see what your monthly expenses will look like in 10, 20, or 30 years — and how that changes your FIRE number.

How this is calculated
Blended inflation rate
r_eff = Σ (weight_i × inflation_i) / 100
Each category's inflation rate is weighted by its share of your total spend. Weights must sum to 100%.
Future monthly spend
Future = Present × (1 + r_eff)^years
Standard compound growth formula applied to monthly expenses using your blended effective inflation rate.
India-specific category rates
- Daily needs & groceries — ~6% (CPI food)
- Housing & rent — ~7% (urban rental index)
- Health & medical — ~10% (healthcare CPI)
- Education (private) — ~11% (tuition trend)
Why not just use 6%?
If your spending skews toward healthcare or education, your personal inflation is meaningfully above CPI. A 2pp difference over 25 years roughly doubles your monthly spend — and therefore your required FIRE corpus.
A note worth reading before you act
The FIRE math works — but equity returns are not a guarantee. Every projection on this site uses long-term historical averages as a baseline. Markets can and do deliver a decade of poor returns, and if that decade happens to be the early years of your retirement, it puts real pressure on even a well-sized corpus. This isn't a reason to not pursue FIRE. It is a reason to build in margin.
The single most effective safety net is an active income source — even a small one. Freelance work, consulting, a part-time role, rental income. If your portfolio has a bad year and returns 6% instead of 12%, ₹15,000–₹25,000 a month of outside income means you don't have to redeem units at a loss while the market is down. You simply wait.
Financial independence is worth building towards. But “retired” doesn't have to mean “never earns again.” Keep a skill that someone will pay you for. Treat your corpus target as a floor, not a finish line. The goal is resilience — not just a number.
