"Enough" is not a vague feeling — it is a number you can calculate. Roughly, you need a savings fund of about 25 to 30 times your expected annual expenses in retirement, so that drawing around 4 % a year can sustain you for decades.
The step almost everyone skips: your expenses must be measured in future rupees, not today's. Inflation between now and retirement, and then across a long retirement, is what makes the honest number so much larger than people expect.
With your net-worth statement in hand, this lesson gives you the target to compare it against. The maths is not hard, but it is unforgiving of wishful thinking — and being honest now, with 10 years to act, is far better than being surprised later with none.
Begin with your actual yearly expenses
Everything begins with what you actually spend in a year — not your income, your spending. In retirement some costs fall (commuting, work clothes, supporting children, your own retirement saving) while others rise (health, leisure, help around the home). A reasonable starting estimate is a large fraction of your current spending, adjusted for these shifts.
Suppose that comes to ₹75,000 a month today, or ₹9,00,000 a year. That is the figure everything else builds on — and note it is today's figure, which is exactly where the honesty begins.
Remember to increase expenses for future inflation
You will not retire on today's prices. If retirement is 10 years away and inflation runs about 6 %, that ₹9,00,000 of annual expense becomes roughly ₹16,10,000 a year by the time you retire — the same lifestyle, nearly doubled in rupees.
So the fund you need is not 25 times today's expense but 25 times the future expense: around ₹4,03,00,000, not the ₹2,25,00,000 that today's figure would suggest. Skipping this single step is why so many people arrive at retirement with what looks like a large sum and discover it is not nearly enough. The number must be in the rupees you will actually spend.
The 25-times rule in simple words
The guideline is that a savings fund of about 25 times your annual expenses can sustain roughly a 4 % withdrawal each year, rising with inflation, for a long retirement without running out — because a sensibly invested fund keeps earning while you draw from it. 25 times gives a 4 % draw; a more cautious thirty times, a 3.3 % draw, gives more safety for a very long retirement or an uncertain one.
These are rules of thumb, not guarantees — real markets do not deliver smooth returns, and the sequence of good and bad years matters, especially early in retirement. But as a target to aim at in this decade, 25 to 30 times your future annual expense is a sound, honest benchmark.
Compare the amount you need with what you have
Now bring the two numbers together. Take your investable net worth, project how it grows over your remaining years, and see how it compares to the target. An illustration makes the shape clear.
| Target fund (25× future expense) | ₹4,03,00,000 |
| Existing ₹80,00,000, grown at 10% | ₹2,07,50,000 |
| Gap still to build | ₹1,95,50,000 |
That monthly figure may be daunting, and that is the point of doing this now. If the gap is unbridgeable at your current savings rate, you have 10 years and several practical options available — not the fear of discovering it at retirement with none.
What to do when the target looks too high
Frequently the honest target exceeds what current savings can reach, and that is useful information, not a verdict. You have practical choices, and this decade is when they still work:
- Save more now — these are often your highest-earning years, with children's costs falling; the surplus can be directed hard at the gap.
- Retire a little later — even two or three extra years both add to the fund and shorten the period it must fund, a useful change in two ways.
- Spend a little less in retirement — lowering the annual expense reduces the target savings proportionally, since it is a multiple of that figure.
- Unlock the home — downsizing, or a reverse mortgage, can convert property wealth into retirement income if needed.
Usually a combination of modest moves closes a gap that looks hopeless as a single number. The value of calculating "enough" carefully is exactly that it turns a vague dread into a set of concrete, workable choices while there is still time to make them.
A common mistake
Calculating the fund against today's expenses and ignoring inflation. It produces a target far too low, and a dangerous false confidence — people aim at ₹2.25 crore when the honest figure is ₹4 crore, and reach retirement short. Always inflate your expenses to the year you will actually retire, and remember they keep rising throughout retirement too.
The second mistake is refusing to calculate at all because the number frightens you. The gap does not shrink by being ignored; it only becomes unfixable. Facing it with a decade to spare is what makes it solvable. An honest scary number beats a comfortable wrong one every time.
Simple meanings
- Corpus
- The total pot of money you retire on and draw an income from.
- The 25x rule
- A target savings of about 25 times annual expenses, supporting a ~4% yearly withdrawal.
- Withdrawal rate
- The percentage of your savings drawn each year. Around 4% is a common sustainable guide.
- Real vs nominal
- Real is after inflation; nominal is the headline number. Retirement planning must use future (inflated) figures.
- Sequence risk
- The danger of poor returns early in retirement, which can damage a savings fund disproportionately.
- Reverse mortgage
- A way to draw income from a home you keep living in, unlocking its value in retirement.
