ChartFormula usedRetirement corpus via inflated expenses, real return, and reverse SIP solving
Monthly expenses are first inflated until retirement, then discounted using a real post-retirement return derived from post-retirement return minus inflation. Projection mode estimates whether a chosen monthly SIP reaches that corpus, while goal mode solves the monthly SIP required to close the gap.
Goal mode reuses the same retirement target math, then solves backwards for the monthly SIP required to close the corpus gap by retirement age.
AssumptionsBase scenario
- Monthly expenses rise with a constant inflation rate until and through retirement.
- Pre-retirement and post-retirement returns stay stable across the plan horizon.
- Scenario bands adjust inflation and return assumptions only; they do not change spending patterns or longevity.
- Withdrawals are modeled as evenly funded living expenses rather than irregular large expenses.
- Uses the exact inflation and return inputs entered on the page.
Limits and freshnessUpdated 2026-04-03
- Healthcare spikes, one-time expenses, and changing lifestyle costs are not modeled separately.
- The calculator assumes the same inflation trend throughout retirement, which may differ from real spending patterns.
- Taxes on withdrawals, pensions, annuities, or other income sources are not deducted in the base projection.
Stress-test the plan with slightly higher inflation and a lower post-retirement return before locking in the required SIP.

About Retirement Calculator
Guide1Why Retirement Planning Matters
Retirement planning is the process of determining your financial goals for retirement and creating a strategy to achieve them. With increasing life expectancy in India (now averaging 70+ years) and rising healthcare costs, planning for a retirement that could last 25-30 years is essential.
The earlier you start planning, the more time your investments have to compound. A person who starts investing ₹10,000 per month at age 25 can accumulate significantly more than someone investing ₹30,000 per month starting at age 40, thanks to the power of compounding.
2Retirement Corpus Estimation
Your required retirement corpus depends on several factors:
Required Corpus = Annual Expenses at Retirement × (1 - (1+g)^(-n) / (r-g))
Where g is the inflation rate, r is the post-retirement return rate, and n is the expected years in retirement. A simpler approach:
- Step 1: Estimate your current annual expenses
- Step 2: Inflate them to your retirement age using expected inflation
- Step 3: Multiply by 25-30 to get the required corpus
3How to Use This Retirement Calculator

4Retirement Investment Strategy
- 20s-30s: Aggressive allocation — 70-80% equity for long-term growth
- 40s: Balanced allocation — 50-60% equity, rest in debt and fixed income
- 50s: Conservative shift — 30-40% equity, increase debt allocation
- Post-retirement: Capital preservation — 20-30% equity, focus on regular income instruments like SCSS, PMVVY, debt funds
