Calculate the retirement corpus you may need to maintain your lifestyle after retirement. Estimate future expenses, inflation-adjusted costs, retirement savings, and monthly retirement income using our free Retirement Calculator.
Planning for retirement requires projecting inflation-adjusted monthly living expenses and computing a terminal corpus capable of sustaining withdrawals across a 25-to-35 year post-retirement horizon without principal exhaustion.
Estimate your retirement corpus, future expenses, and savings requirements based on inflation and retirement goals.
While the US Trinity Study suggests a 25x annual expense corpus (4% withdrawal rate), Indian retirement planners recommend a 30x to 33x multiple (3%–3.33% safe withdrawal rate) to compensate for India's higher 6% average retail inflation and longer life expectancy.

A Retirement Calculator estimates the amount of money you may need after retirement based on expenses, inflation, retirement age, and expected lifespan.

| Factor | Impact |
|---|---|
| Current Age | Earlier start allows more compounding. |
| Retirement Age | Determines investment duration. |
| Monthly Expenses | Higher expenses require a larger corpus. |
| Inflation | Reduces future purchasing power. |
| Expected Returns | Affects corpus growth over time. |
| Starting Age | Advantage |
|---|---|
| 20s | Maximum benefit from compounding. |
| 30s | Good balance of income and growth. |
| 40s | Requires higher monthly investments. |
| 50s | Focus on preservation and income. |
Inflation can significantly reduce the value of money over time. An expense of ₹50,000 per month today may require more than ₹1 lakh per month after 20 years depending on inflation rates.
| Monthly Expense | Suggested Retirement Corpus |
|---|---|
| ₹25,000 | ₹75 Lakh - ₹1 Crore |
| ₹50,000 | ₹1.5 Crore - ₹2 Crore |
| ₹1,00,000 | ₹3 Crore - ₹4 Crore |
| Age Group | Suggested Equity Allocation |
|---|---|
| 20-30 Years | 70% - 90% |
| 30-40 Years | 60% - 80% |
| 40-50 Years | 50% - 70% |
| 50+ Years | 30% - 50% |
A person investing ₹10,000 per month from age 25 can accumulate significantly more wealth than someone investing ₹20,000 per month starting at age 40. Time is one of the most important factors in retirement planning.
A common rule is to save at least 15% of your annual income toward retirement. Increasing investments whenever your salary increases can dramatically improve your retirement corpus.
