Retirement Planning Basics: How Much Do You Need?
Retirement is a long period without a salary, and it can last 25 to 30 years or more. Planning early makes it far easier. This guide explains how to estimate the corpus you need, in simple steps. It is general education, not personal advice.
Key takeaways
- Think in terms of future expenses, not today’s. Inflation raises your monthly cost every year.
- A common rule of thumb is a corpus of roughly 25 times your yearly expenses, but it is only a starting point.
- Starting early does more for you than investing a higher amount later.
Step 1: Estimate your expenses
Start with your current monthly spending and think about what will stay, shrink or grow. Loan EMIs and school fees may end, while healthcare usually rises. Then project the figure to your retirement date.
Step 2: Account for inflation
Prices rise every year, so ₹50,000 today will not buy the same goods in 25 years. An assumed inflation rate is a planning guess, not a prediction, so test a few values.
Step 3: Work out the corpus
The popular 4% rule suggests you can withdraw about 4% of your corpus in the first year and adjust for inflation later. That equals a corpus of 25 times yearly expenses. Treat it with caution: it was built from other markets, your retirement may be longer, and returns in a bad early period can hurt badly. Many people prefer a lower withdrawal rate or a larger buffer.
Worked example
Say your expenses are ₹50,000 a month today, you retire in 25 years and assume 6% inflation.
Future monthly expense = 50,000 × 1.0625 ≈ ₹2,14,594. Yearly expense ≈ ₹25.75 lakh. At 25 times yearly expenses, the corpus is about ₹6.44 crore. In today's money the same rule gives 25 × ₹6 lakh = ₹1.5 crore, which shows how much inflation matters.
That looks large, but a monthly SIP over 25 years does much of the work through compounding.
Why starting early wins
Compounding rewards time. Someone who starts at 25 needs a much smaller monthly amount than someone who starts at 40 for the same target. If you cannot invest a lot now, start small and step the amount up as your income grows.
Asset mix by age (general idea)
- 20s and 30s: a higher share in equity, since you have decades to ride out falls.
- 40s and 50s: gradually add debt such as PPF, EPF and bonds to reduce swings.
- Near and after retirement: keep a few years of expenses in safer assets, with some equity to beat inflation.
Your own mix depends on your risk comfort, income stability and other assets. Consider speaking to a registered adviser.
Other points to remember
- Count EPF, NPS and any pension you will receive.
- Buy adequate health insurance before you retire.
- Review your plan every year.

Frequently asked questions
Is the 4% rule safe in India?
It is a rough guide from other markets. Longer retirements and higher inflation mean many planners suggest a lower rate or a bigger buffer.
How much should I save each month for retirement?
It depends on your target, age and expected returns. Use the retirement planner with several assumptions and revisit it yearly.
Should I stop investing in equity after 50?
Not necessarily. Many retirees keep some equity to fight inflation, while shifting more to safer assets. The right mix depends on your situation.
Does EPF count towards my corpus?
Yes. Add the expected EPF, NPS and any other retirement assets to your estimate.
