How much pension will you need when you retire?
Most people pick a retirement number out of thin air: a round crore, or whatever a friend mentioned. A better starting point is the life you live today. Three simple steps turn that into the monthly pension you'll need, and the pot it takes to pay for it.
Step 1: Start with what your household spends today
Add up a normal month: groceries, electricity and phone bills, rent or society maintenance, transport, medicines and doctor visits, help at home, eating out, travel and family occasions. Spread big yearly costs, like insurance premiums or a holiday, across the twelve months.
Leave out the costs that will have ended by the time you retire: home loan EMIs that will be paid off, your children's school or college fees, and the money you save each month.
Step 2: Add the effect of inflation
Prices rise every year, so the same lifestyle will cost much more by the time you retire. If your household spends ₹50,000 a month today and you retire in 25 years:
| Inflation each year | What ₹50,000 a month becomes in 25 years |
|---|---|
| 5% | about ₹1.69 lakh a month |
| 6% | about ₹2.15 lakh a month |
That isn't a typing error. At 5% inflation, prices roughly double every 14 years, so over 25 years they grow more than three times. This is the single most common reason people under-save for retirement.
Step 3: Turn the monthly need into a pension pot
At retirement, you can use your savings to buy an annuity: a fixed monthly income for life from an insurance company. The annuity rate tells you how much income each rupee buys. That gives a simple formula:
Pension pot needed = monthly need × 12 ÷ annuity rate
For a monthly need of ₹1.69 lakh and an annuity rate of 7%, that's ₹1.69 lakh × 12 ÷ 0.07, or about ₹2.90 crore.
What changes after you retire
Costs that usually fall
- Daily travel to work
- Loan EMIs, if paid off
- Work clothes, lunches and other work costs
Costs that usually rise
- Healthcare and medicines, often faster than general inflation
- Travel and time with family
- Help at home as you get older
For most families these roughly balance out, which is why planning for the same lifestyle you have today is a sensible starting point.
Four common mistakes
- Ignoring inflation. Planning for today's ₹50,000 instead of tomorrow's ₹1.7 lakh.
- Relying on one source. EPF or gratuity alone rarely covers 25 to 30 years of retirement.
- Planning for too short a life. Many people now live into their late 80s; plan for at least that long.
- Waiting to start. Every year of delay makes the monthly amount you need noticeably bigger. See what waiting really costs.
