Stress test your budget and portfolio longevity under three inflation scenarios. Model Moderate (6%), High (10%), and Hyperinflation (15%) conditions.
Inflation is the silent killer of wealth. A constant 6% inflation doubles your cost of living every 12 years. If inflation spikes to 10% or 15% (hyperinflation/stagflation), cash loses half its value in less than 5 years. Use this tester to model expense spikes and portfolio life span side-by-side.

Your ₹2,50,00,000 nest egg will feel like:
| Asset Class | Moderate Inflation (6%) | High Inflation (10%) | Hyperinflation (15%) |
|---|---|---|---|
| Equities / Index Funds | Excellent (+12% CAGR, strong real growth) | Good (companies raise prices to offset costs) | Volatile (multiple compression, supply shocks) |
| Gold (Commodity) | Moderate (acts as a standard dollar store value) | Excellent (safe haven hedge spikes gold premiums) | Outstanding (ultimate fiat escape currency) |
| Real Estate (Rental) | Strong (rents escalate at 8% p.a.) | Strong (property value appreciates with inflation) | Moderate (high capital cost & loan EMIs stress sales) |
| Fixed Deposits & Cash | Negative Real Returns (FD at 7% vs 6% tax) | Destructive (loses 3-4% purchasing power p.a.) | Catastrophic (rapid capital corrosion/halves in 5 yr) |
💡 **Portfolio Action Plan:** To battle a high inflation cycle, reduce pure cash holdings. Shift towards gold commodities (10-15%) and high-pricing-power equities (50-60%) which act as organic escalators to beat the CPI.
Inflation is the single greatest threat to long-term wealth preservation. Over a 20 or 30-year horizon, even a modest inflation rate of 6% will more than double your living expenses, while a high inflation shock can completely destroy the purchasing power of cash in just a few years.
Most retirement calculators make the mistake of using a single, static inflation rate. The Inflation Stress Tester models your budget and investment corpus under three distinct scenarios:
This tester runs two core financial calculations over your timeline:
The compounding effect of inflation on nominal prices is calculated as:
Future Annual Expense = Current Annual Expense * [ 1 + Inflation Rate / 100 ]^Years
For example, if your current monthly expenses are ₹60,000 (₹7.2 Lakhs annually):
The decay in the real value of a fixed sum of savings (e.g. a ₹2.5 Crore corpus) is calculated as:
Future Real Value = Current Corpus / [ 1 + Inflation Rate / 100 ]^Years
In 20 years, a ₹2.5 Crore cash corpus:
The tester calculates how many years your savings corpus will last before dropping to zero. It runs a year-by-year cash depletion simulation where your corpus compounds at your expected portfolio return rate, while expenses are withdrawn at the start of each year and inflated:
Balance (y) = [ Balance (y - 1) - Inflated Expense (y) ] * [ 1 + Portfolio Return / 100 ]
This shows you exactly how a small change in inflation can slash your retirement longevity from 40 years to less than 12 years, forcing you to seek inflation-hedging assets.
Equities (mutual funds/stocks) and real estate are historically the best long-term hedges because company earnings and property values generally rise in tandem with consumer prices. Physical Gold is also a traditional store of value. Fixed Deposits (FDs) are poor hedges because their post-tax returns rarely beat inflation.
The Rule of 72 calculates how fast the purchasing power of your money will cut in half. Simply divide 72 by the inflation rate. Under 6% inflation, your money loses half its value in 12 years. Under 10% inflation, it takes only 7.2 years.
If inflation rises, you are forced to withdraw larger nominal sums each year to maintain the same standard of living. If your portfolio returns do not keep pace, this accelerates sequence risk, making dynamic guardrails necessary.
