Why Consider Inflation in SWP?
Standard SWP calculators show nominal values—the actual rupee amounts you'll have. But inflation silently erodes your purchasing power over time. ₹50,000 today won't buy the same amount of goods 20 years from now. This advanced SWP calculator helps you understand: • **Nominal Balance**: The actual rupee amount in your portfolio • **Real Balance**: What that money is worth in today's purchasing power • **Inflation-Adjusted Withdrawals**: Option to increase withdrawals yearly to maintain your lifestyle At 6% inflation, prices double every 12 years. A monthly expense of ₹50,000 today will need ₹1,00,000 in 12 years just to maintain the same standard of living. Planning without accounting for inflation can lead to a severe shortfall in retirement.
Inflation-Adjusted Withdrawal Formula

- Toggle 'Inflation-Adjusted Withdrawals' to see different strategies
- Compare Nominal vs Real balances to understand true value
When Should You Use This Calculator?
- Planning retirement withdrawals for 20+ year horizons
- Understanding the true "real" return on your investments
- Deciding between fixed vs. inflation-adjusted pensions
- Stress-testing your retirement corpus against various inflation scenarios
- Calculating the minimum corpus needed to beat inflation over time
- Comparing outcomes of different withdrawal strategies
Real-World Examples
Retirement Reality Check
You have ₹1 Crore corpus, planning to withdraw ₹40,000/month for 25 years.
💡 While you end with ₹85 Lakhs nominally, it's only worth ₹20 Lakhs in today's money. With inflation-adjusted withdrawals, plan for ₹1.73 Lakhs/month in year 25!
Safe Withdrawal Rate
Testing the 4% rule with Indian inflation.
💡 The 4% rule (adjusted for Indian conditions) works because your real return (8%-6%=2%) plus some principal depletion supports long-term withdrawals.
Fixed vs. Inflation-Adjusted Withdrawals
Understanding the trade-off between withdrawal strategies.
| Aspect | Fixed Withdrawals | Inflation-Adjusted Withdrawals |
|---|---|---|
| Monthly Amount | Same every month (e.g., ₹30K) | Increases yearly (₹30K → ₹32K → ₹34K...) |
| Purchasing Power | Decreases over time | Maintained (or nearly so) |
| Corpus Longevity | Lasts longer | Depletes faster |
| Early Retirement Years | More surplus (can save/reinvest) | Just enough for expenses |
| Later Retirement Years | May face shortfall | Expenses covered |
| Best For | Short horizons, or with other income | Long retirements (25+ years) |
Inflation Mistakes in Retirement Planning
Using Nominal Returns Only
The Issue:A 10% return sounds great, but with 6% inflation, your real return is only ~4%. Planning based on 10% leads to overconfidence.
Fixed Withdrawals Throughout Retirement
The Issue:Withdrawing ₹30,000/month for 25 years means severe lifestyle compromise in later years as inflation erodes purchasing power.
Underestimating Healthcare Inflation
The Issue:Medical costs in India inflate at 10-15%, much higher than general inflation of 5-7%.
Pro Tips for Inflation-Proof SWP
The 4% Rule in Indian Context
The famous 4% withdrawal rule originated from US studies. For India, with higher inflation (6% vs 2-3% in US), the safe withdrawal rate may be closer to 3-3.5%. However, equity returns in India have also been higher (12-15% vs 8-10%), which can compensate. This calculator helps you test different scenarios for your specific situation.
Sequence of Returns Risk
Market crashes in early retirement years are devastating for SWP. If markets fall 30% in year 1 of your retirement, you're forced to sell more units for the same withdrawal, permanently depleting your corpus faster. Always keep 2-3 years of expenses in stable debt funds as a buffer.
Frequently Asked Questions
What is a realistic inflation rate to use for India?
For long-term planning, use 5-6% for general expenses. Healthcare costs inflate at 10-12%. If you're planning 25+ years, it's wise to stress-test with 7% inflation. The RBI targets 4% but actual CPI has often been 5-6%.
Should I always use inflation-adjusted withdrawals?
Not necessarily. If you have other income sources that increase with inflation (rental income, annuities), fixed withdrawals from your SWP might be fine. Inflation-adjusted makes sense when this is your primary income source for a long retirement.
How does this differ from the regular SWP calculator?
The regular SWP calculator shows only "nominal" values. This calculator shows both nominal and "real" (inflation-adjusted) values, helping you understand what your money will actually be worth in terms of today's purchasing power. It also lets you model withdrawals that increase with inflation.
What's the difference between nominal and real balance?
Nominal balance is the actual rupee amount in your account. Real balance is what those rupees are worth in today's money. Example: ₹1 Crore after 20 years at 6% inflation is worth only ₹31 Lakhs in today's terms.
My real balance looks scary—should I save more?
Seeing your 'real' balance decline is expected because you're withdrawing and fighting inflation. The key metric is whether your corpus lasts your entire retirement while providing desired withdrawals. If it does, you're fine. If not, either increase savings, reduce planned withdrawals, or extend your working years.
