Most of us know our salary to the rupee. Ask how many months we could live without it, or how much we need to retire, and the answer is usually a shrug.
Five numbers fix that. Together they tell you, in about ten minutes, whether your money is on track — and which gap to close first. None of them needs a spreadsheet. All of them need honesty.
The figures below are common rules of thumb and simple arithmetic, not personal advice. Your own numbers depend on your family, job, health and goals.
Number 1: Your savings rate
Your savings rate is the share of take-home pay you save and invest before spending. It matters more than any return you will ever earn, because it is the one number fully in your control.
A common target is at least 20% of take-home pay. If you are early in your career with few commitments, 30% or more is often realistic. The trick that makes it stick is automation: the SIP or transfer goes out the day after salary lands, and you spend what is left.
| Take-home pay a month | 20% savings rate | 30% savings rate |
|---|---|---|
| ₹60,000 | ₹12,000 | ₹18,000 |
| ₹1,00,000 | ₹20,000 | ₹30,000 |
| ₹1,50,000 | ₹30,000 | ₹45,000 |
If 20% feels impossible today, start at 10% and raise it by a point or two every time your salary rises.
Number 2: Your emergency fund
An emergency fund is money you can reach within a day, for a job loss, a medical bill or an urgent repair. Its job is to stop you from breaking your investments or borrowing at credit-card rates when life happens.
The usual rule of thumb is six months of essential expenses — rent or EMI, groceries, utilities, school fees, insurance premiums. Three months can be enough if your income is very stable and your family has a second earner; self-employed people often keep nine to twelve.
| Essential expenses a month | 3 months | 6 months |
|---|---|---|
| ₹40,000 | ₹1.2 lakh | ₹2.4 lakh |
| ₹60,000 | ₹1.8 lakh | ₹3.6 lakh |
| ₹90,000 | ₹2.7 lakh | ₹5.4 lakh |
Keep it somewhere boring and liquid: a savings account, a sweep-in fixed deposit or a liquid fund. The point is access, not return.
Number 3: Your term insurance cover
If anyone depends on your income, term insurance replaces that income if you die. It is the cheapest form of life cover because it pays only on death and has no investment component.
A common rule is cover of 10 to 15 times your annual income, plus any loans you would not want to leave behind. Younger earners with long-dependent families tend toward the higher end.
| Annual income | 10 times | 15 times |
|---|---|---|
| ₹7.2 lakh | ₹72 lakh | ₹1.08 crore |
| ₹12 lakh | ₹1.2 crore | ₹1.8 crore |
| ₹18 lakh | ₹1.8 crore | ₹2.7 crore |
If you have no dependants, you may not need term cover yet. If you have a home loan, add the outstanding balance.
Number 4: Your health cover
Health insurance protects number 2. One hospital stay can cost more than six months of expenses, and a policy through your employer usually ends when the job does.
There is no single right number, but two checks help. First, would your cover pay for a serious hospital stay at the hospital you would actually use, in your city? Second, would it survive a job change? Many families pair a base family floater with a super top-up, which adds a large amount of cover for a lower premium once a threshold is crossed. Read the room-rent limits, waiting periods and co-pay terms before you buy — they matter more than the headline amount.
Number 5: Your retirement number
Your retirement number is the corpus you need to stop working, expressed as a multiple of the yearly expenses you expect at retirement.
A widely used rule of thumb is 25 times annual expenses. It comes from the idea of withdrawing about 4% a year. Many planners in India use 30 times or more, because inflation here has historically run higher than in the countries where the 4% idea was studied, and retirements are getting longer.
Here is how it works for one person.
- Age 35, wants to retire at 60: 25 years to go.
- Spends ₹60,000 a month today: ₹7.2 lakh a year.
- Assumes prices rise 6% a year (an assumption, not a forecast).
- In 25 years, the same lifestyle costs about ₹31 lakh a year (₹7.2 lakh × about 4.29).
- At 25 times, the retirement number is about ₹7.7 crore. At 30 times, about ₹9.3 crore.
That looks frightening. Here is the part that makes it reachable.
| Monthly SIP for 25 years | Assumed 10% a year | Assumed 12% a year |
|---|---|---|
| ₹20,000, same every year | about ₹2.5 crore | about ₹3.4 crore |
| ₹20,000, raised 10% every year | about ₹6.2 crore | about ₹7.9 crore |
The step-up does the heavy lifting. Raising the SIP each year, in line with salary, more than doubles the result from the same starting amount. Try your own numbers in our SIP calculator, or see the other free tools in the Money Toolkit.
These returns are assumptions for illustration. Equity returns are not guaranteed, they vary widely from year to year, and they can be negative for long stretches. Plan with a margin for error and review the plan every year.
Putting the five together
Here is the full check for one household: take-home ₹1 lakh a month, essential expenses ₹60,000, age 35, one dependent spouse and a child.
| Number | Rule of thumb | This household’s target |
|---|---|---|
| Savings rate | At least 20% | ₹20,000 a month |
| Emergency fund | 6 months of essentials | ₹3.6 lakh |
| Term cover | 10–15 × annual income | ₹1.2–1.8 crore |
| Health cover | Covers a serious stay in your city, survives a job change | Family floater plus top-up |
| Retirement number | 25–30 × expenses at retirement | ₹7.7–9.3 crore by 60 |
Where to start
Write your five numbers down. Next to each, write the target. Then fix them in this order: emergency fund and insurance first, because they protect everything else; then the savings rate; then the retirement number, which the savings rate and time take care of.
