Every investor faces the same question at some point. You have money saved. Part of it can go into shares, which grow well over long periods but can also fall hard in a bad year. Part of it can go into bonds, which pay a fixed return and move far less. What you have to decide is the split between the two.
For a conservative investor, that split matters more than for anyone else. A conservative investor is someone who cares more about protecting money than growing it quickly: hold too much in shares, and one bad year can take away savings you were counting on; hold too much in bonds, and your money grows slower than prices rise. Getting that balance right is what a conservative investment portfolio in India is for.
Most people settle this with a shortcut. Subtract your age from 100. That number is the allocation for shares. The rest goes into bonds. So a 30-year-old holds 70% shares and 30% bonds. A 70-year-old holds the opposite.
The shortcut is easy to remember and easy to apply. It is also a weak answer to how much to invest in bonds, because it uses one fact about you and ignores three others that matter just as much. Age on its own cannot tell you how much to invest in bonds.

Where the Age Rule Breaks
Age is a rough stand-in for time. The thinking is simple. A young person has decades to recover from a bad year in shares. Someone near retirement does not. That part is fair, and it is why age appears in every guide on how much to invest in bonds. The problem is what the rule leaves out.
It assumes all your money is needed at retirement. If you plan to buy a house in four years, that money cannot sit in shares, whatever your age is. It also assumes every 40-year-old earns the same way. A salaried person with a steady job and a freelancer with uneven income should not hold the same asset allocation, even at the same age.
It assumes you will sit still during a crash. Many people do not. They sell near the bottom, which turns a paper loss into a real one. Someone who panics with 70% in shares would have been better off with 50%.
So treat the age rule as a starting number. Then adjust it. Those adjustments decide how much to invest in bonds for you, and the adjustments are where the real answer actually lives.

The Four Things That Decide Your Number
These four points do more to set your asset allocation than your age does. Work through them, and you will have a real answer on how much to invest in bonds.
- When you need the money: This matters more than anything else on the list. Money you need within three years should be in bonds or deposits. Not because shares are bad, but because three years is not enough time to recover if the market falls in year two. Money you do not need for ten years can sit mostly in shares, so the date decides how much to invest in bonds far more than the age rule does. A conservative investment portfolio in India usually gets built around this one rule, because dates are the only part of investing you actually control.
- How steady your income is: If your salary arrives on the same date every month, you can hold more in shares, because you will not be forced to sell during a bad patch. If your income moves up and down, you need a larger cushion of safe investment options to cover the gaps. Uneven income raises how much one should invest in bonds, at any age.
- How you behaved the last time markets fell: Check what you actually did in the last big fall. If you sold, your real capacity for risk is lower than your age suggests, and your split of bonds and equity should reflect that. A plan you abandon is worse than a cautious plan you stick to. Safe investment options are only useful if you actually hold them.
- What the money is for: A school fee has a fixed date and cannot be postponed. A holiday can wait a year. Money tied to a fixed date belongs in bonds. Money with a flexible date can take more risk. Fixed dates raise how much to invest in bonds. Flexible dates lower it.
What You Are Actually Choosing Between
Deciding how much to invest in bonds is easier when you can see what each option pays. These are the rates available now, and they show what safe investment options in India currently pay.
| Where the money sits | Rate now | What protects you |
| Bank savings account | 2.5% to 4% | Deposit insurance up to ₹5 lakh per bank |
| PPF | 7.1% [1] | Government backing, but locked for 15 years |
| Five-year SBI fixed deposit | 6.80% [2] | Deposit insurance up to ₹5 lakh per bank |
| AAA-rated PSU bonds | 6.85% to 7.05% [3] | Government-owned issuer |
| Top-rated NBFC bonds | 7.4% to 8.5% [4] | Company balance sheet only |
| AA-rated housing finance bonds | 8.0% to 9.5% [3] | Company balance sheet, thinner cushion |
Rates as of mid-2026. They change with the market and with each issuer’s rating.
Read that list from top to bottom, and the trade is clear. Every step up in return is a step down in how much protection stands behind your money. That is the choice a conservative investor is really making, and it is the reason to invest in bonds at the safer end of that list.
The Number Should Not Stay Fixed
Your split of bonds and equity is not a decision you make once at 25 and never touch. Three events should make you revisit it.
A goal moves within three years of you. This is the most common one and the most ignored. Money for a fee due in 2029 should not still be in shares in 2028. Move it into bonds while you can choose the moment rather than being forced into it. This single habit fixes most of what goes wrong in a conservative investment portfolio.
Your income changes. A job loss, a switch to freelancing, or a new loan all reduce how much risk you can carry. The share held in safe investment options should rise when your income becomes less certain.
You had a real reaction to a real fall. If a market drop costs you sleep, that is useful information about yourself. Lower your equity share until you can hold it without selling. That is what makes a conservative investment portfolio work in practice.
Reviewing once a year is enough for most people. Reviewing every week is how good plans get broken. A conservative investment portfolio needs attention once a year, not once a day.
Frequently Asked Questions
There is no single number. Start with the rule of thumb for your age, then adjust it using when you need the money, how steady your income is, and how you handled the last market fall. Money needed within three years should be almost entirely in bonds or deposits regardless of your age.
For most people it lands somewhere between 20% and 60%, and the range is wide because the inputs differ so much. A 30-year-old with a stable salary and no near-term goals sits at the low end. A conservative investment portfolio in India tends to sit above 50%. The correct asset allocation is the one that matches your dates, not your age alone. An ideal asset allocation of bonds and equity is personal, not universal.
The common guide is to subtract your age from 100 and put that share in equity, leaving the rest in bonds. Some versions use 110 or 120 instead of 100, which gives a higher equity share. Treat any of these as a starting point. They are useful for a first estimate and poor as a final answer, because they ignore your goals and your income. No single asset allocation fits every person of the same age.
Neither is better in every case. A bank FD is simpler and covered by deposit insurance up to ₹5 lakh per bank, which places it among the safest investment options in India. A bond usually pays more and can be sold in the market before maturity but carries the credit risk of the issuer, so it sits a step below deposits among safe investment options. A five-year SBI FD pays about 6.80% [2]. An AAA-rated PSU bond pays about 6.85% to 7.05% [3]. The gap is small at the top of the rating scale and widens as you go down it.
Usually not. Since July 2024, SEBI has set the minimum face value for privately placed bonds at ₹10,000, down from ₹1 lakh [5]. So ₹10,000 is the common entry point on most platforms today. A small number of public issue NCDs have carried a face value of ₹1,000, but these come to market only occasionally.
Bonds paying around 12% do exist, and they are almost always low-rated or unrated. That rate is not a bargain. It is the price the issuer has to pay because the market sees a real chance of late payment or default. For comparison, AAA-rated PSU bonds pay about 7% right now, and they are among the safe investment options most conservative investors start with. If you see 12%, the useful question is not where to buy it but what the extra 5% is paying for.
Conclusion
Four things decide how much to invest in bonds. Only one of them is your age. Here is a simple way to reach your own number. Start with the figure the age rule gives you. Then raise that figure if any of these is true for you.
- You have a goal that falls due within the next three years.
- Your income is uneven, or less certain than it was.
- You have sold shares during a past market fall.
Lower the figure only if none of those three applies. A conservative investment portfolio should reflect your dates, not a formula. Most people find that at least one of the three applies, which is why the age rule alone usually leaves them holding fewer safe investment options than they need.
A conservative investment portfolio in India is not built by finding the safest product. It is built by matching each rupee to the date you need it. Safe investment options are the tool, not the goal. Get the dates right, and the split of bonds and equity mostly decides itself, and the safe investment options you need become obvious. That is the whole idea behind an ideal asset allocation of bonds and equity.
