How much do you need
to retire?
A simple way to estimate the number, with the arithmetic shown, and what to do about it in the years before and after you stop working.
Ravinder Pal Singh Ubeja ·
Short version: estimate your yearly expenses at the date you retire, multiply by the number of years retirement may last, and subtract what pensions will cover. Build the gap with regular investing while you work, draw it down with a withdrawal plan, consider an annuity for the essentials, and buy your own health insurance before you retire.
A simple way to estimate the number
There are sophisticated retirement models. This one is deliberately simple, so you can do it on paper:
- Step 1: Write down what your household spends in a year today. Leave out costs that will end by retirement, such as EMIs on a loan that will be repaid or children's school fees, and add any that will start, such as higher medical costs.
- Step 2: Inflate it to your retirement year. The formula is expense at retirement = expense today × (1 + inflation)years to retirement. Prices in India have risen every decade; the rate varies, so test more than one assumption.
- Step 3: Multiply by the number of years retirement may last. Plan for longer than you expect; money left over is a far smaller problem than money running out.
- Step 4: Subtract what other income will cover: pension, rent, EPF and NPS balances, and existing investments earmarked for retirement.
Step 3 quietly assumes that, during retirement, your corpus earns roughly enough to keep pace with inflation after tax. It will not grow much in real terms, but it will not shrink much either. That keeps the arithmetic simple and errs on the side of caution.
A worked example (illustration only)
The figures below are assumptions chosen to show the method, not a forecast of inflation or of any investment's return. Use your own numbers.
- Household expenses today: ₹40,000 a month, or ₹4,80,000 a year.
- Years to retirement: 25.
- Assumed inflation for this illustration: 6% a year. Then 1.0625 ≈ 4.29.
- Expenses in the first year of retirement: ₹4,80,000 × 4.29 ≈ ₹20.6 lakh a year, about ₹1.72 lakh a month. Same lifestyle, higher prices.
- Years in retirement: 25 (say from 60 to 85).
- Corpus needed, before other income: ₹20.6 lakh × 25 ≈ ₹5.15 crore.
The number looks large because 25 years of price rises are built into it. Now subtract what is already coming: an EPF balance, a pension, rent from a property. What remains is the gap to build. Changing the assumptions changes the answer a lot, which is why the plan needs a review every few years rather than a single calculation.
Building it: SIP while you earn
For a goal 15 or 25 years away, a monthly SIP in mutual funds, with a large share in equity in the early years, is how most salaried and self-employed families build a retirement corpus. Two habits matter more than fund selection: increase the SIP when your income rises, and do not stop it when markets fall (see what happens to your SIP when the market falls). As retirement approaches, move gradually from equity to lower-volatility options so that a bad year just before you retire cannot derail the plan.
To see how a monthly amount might grow at an assumed rate, use the SIP tab on our calculators page. The rate you enter there is your assumption; actual returns will differ.
Drawing it down: SWP in retirement
A systematic withdrawal plan (SWP) pays you a fixed amount each month from a mutual fund while the rest stays invested. It is flexible, you can change the amount, and only the gain in each withdrawal is taxed, not the whole withdrawal. The risk is that markets fall while you are withdrawing, which is why the money needed in the next few years should sit in lower-risk funds. Try different withdrawal amounts on the SWP calculator.
Annuities: income for life
An annuity, bought from a life insurer, turns a lump sum into a regular income for the rest of your life, or for you and your spouse, at a rate fixed when you buy it. Its strength is certainty: you cannot outlive it. Its weaknesses are that the money is usually locked in and the income is taxable as it is received. A common approach is to annuitise enough to cover essential expenses and keep the rest invested through an SWP for flexibility and growth.
Health insurance after retirement
The most common gap in Indian retirement plans is health cover. Employer group cover ends when the job does. Buying a fresh policy at 60 means medical tests, possible exclusions for existing conditions, and waiting periods that start from zero. Buy your own family floater or individual policy in your forties or early fifties, keep it renewed without a break, and consider a super top-up for larger cover at lower cost. Our health insurance page explains how we review cover for families and parents.
Where to start
Do the four steps above with your own numbers, even roughly. If the gap is large, start or increase an SIP now; time does more of the work than any product. Our mutual funds and SIP page explains how we help families in Raipur and Bilaspur plan this.
