A bonus in insurance is an additional benefit you receive as a share of the profit a company earns. It enhances your policy’s value over time.
Life insurance is a vital financial safety net that every earning individual should consider. It helps to protect your family’s future. When you buy a participating life insurance policy, you may receive a bonus in addition to the guaranteed benefits of the plan.
A bonus in insurance is an extra amount that a life insurance company shares with eligible policyholders from its surplus profits. You can view it as a reward for staying invested in the policy over the long term. This article explains the various types of bonuses in insurance, how insurers declare them, and provides a simple example showing how bonus amounts are calculated.
A bonus in life insurance is an additional benefit that a life insurance company may add to eligible participating (with-profits or par) policies from its distributable surplus. It is a way of sharing a portion of the insurer’s profits with policyholders.
Generally, a life insurer declares a bonus in insurance annually. However, the actual payout may happen at maturity, surrender, or claim settlement, depending on the policy terms. It is essential to note that bonuses are not paid on term insurance plans, unit-linked insurance plans, or non-participating (non-par) life insurance policies.

Insurers declare life insurance bonuses after reviewing the performance of their participating funds and calculating the distributable surplus available for sharing with policyholders. The bonus rate is based on the surplus. It is often expressed per Rs. 1,000 of the sum assured, each year. The insurer then adds the declared bonus to eligible participating policies according to policy terms. Since bonuses depend on the fund’s performance, bonus rates are not guaranteed and can change from year to year.
A reversionary bonus is the most common type of bonus in insurance offered under participating life insurance policies. It is an amount declared by the insurer and added to your policy every year based on the announced bonus rate. However, this bonus is not paid out immediately.
In short, the reversionary bonus meaning comes down to this: it’s the yearly addition an insurer makes to your participating policy, which builds up quietly in the background until a claim or maturity brings it down.
Instead, it accumulates within the policy and becomes payable when the policy matures or when a death claim is settled. After an insurer declares the reversionary bonus and it is attached to the policy, it generally cannot be taken back. Reversionary bonuses are usually classified as either a simple reversionary bonus or a compound reversionary bonus.

A simple reversionary bonus is calculated only on the original sum assured of the policy and not on previously declared bonuses. If the insurer declares a bonus each year, the same calculation method is used annually based on the base sum assured. As a result, the bonus accumulates steadily over the policy term.
For example, if the sum assured is Rs. 10 lakh and the bonus rate is Rs. 40 per Rs. 1,000, the annual bonus would be Rs. 40,000.
Formula breakdown:
A compound reversionary bonus is calculated on the original sum assured and the bonuses that have already been added to the policy. This means each year’s bonus can earn further bonuses in future years, creating a compounding effect. As a result, the accumulated bonus may grow faster than a simple reversionary bonus, especially over a long policy term. Due to this compounding nature, the final benefit can be significantly higher over time.

Using the same Rs. 10 lakh sum assured and a 4% (Rs. 40 per Rs. 1,000) bonus rate, here is how simple and compound reversionary bonuses compare over five years:
| Year | Simple Bonus (Cumulative) | Compound Bonus (Cumulative) |
| 1 | Rs. 40,000 | Rs. 40,000 |
| 2 | Rs. 80,000 | Rs. 81,600 |
| 3 | Rs. 1,20,000 | Rs. 1,24,864 |
| 4 | Rs. 1,60,000 | Rs. 1,69,859 |
| 5 | Rs. 2,00,000 | Rs. 2,16,653 |
By year 5, the compound bonus works out to roughly 8% more than the simple bonus, purely because each year’s bonus starts earning its own bonus on top of the sum assured.
A cash bonus is a type of life insurance bonus that is paid directly to the policyholder during the policy term. It is not added to the policy’s maturity or death benefit. Life insurers declare this type of bonus in insurance annually on eligible participating policies and may be expressed as a percentage of the sum assured or in another specified form. Since the bonus is paid out immediately, policyholders can use the money as they wish without waiting for the policy to mature.
An interim bonus is a bonus that may be paid when a policy matures, or a death claim arises between two regular bonus declaration dates. It covers the period from the last declared bonus up to the claim or maturity date. This helps ensure that the policyholder or nominee receives a fair share of the surplus earned during that part of the year and is not disadvantaged simply because the claim occurred before the next annual bonus declaration.
A terminal bonus in insurance is a one-time additional bonus that may be paid when a participating life insurance policy matures or when a death claim is settled. It is often viewed as a loyalty or persistence reward for policyholders who keep their policies active for a long period or until the end of the policy term. Unlike reversionary bonuses, a terminal bonus is discretionary and not guaranteed. The amount and whether or not it is paid depend on the insurer’s performance and bonus policy.
A vested bonus is not a separate type of life insurance bonus. Instead, it refers to the total reversionary bonuses that have already been declared by the insurer and attached, or ‘vested,’ to a participating policy. Once vested, these bonuses become part of the policy benefits and are generally payable at maturity or on a death claim, depending on the policy terms. In simple words, a vested bonus is the accumulated value of declared reversionary bonuses.
Knowing how to calculate insurance bonus amounts is mostly a matter of applying one formula consistently, whether you’re checking a simple or a compound bonus.
If you want to know how to calculate the insurance bonus, the formula is given below:
Bonus = (Bonus rate per Rs. 1,000 / 1,000) X sum assured X number of years
Let’s understand how to calculate the insurance bonus with the help of an example. The sum assured is Rs. 10 lakh, the bonus rate is Rs. 40 per Rs. 1,000, and the policy runs for 10 years.
Bonus = 40 / 1000 X 100000 X 10 = Rs. 4 lakh
Under a compound reversionary bonus, the bonus is calculated on the sum assured plus previously declared bonuses. Thus, the total bonus grows faster over time and is usually higher than the simple reversionary bonus.
The timing of bonus payouts depends on the type of bonus in insurance.
| Bonus type | How is it calculated? | When is it paid? | Is it guaranteed? |
| Reversionary bonus | Declared periodically and added to the policy based on the insurer’s bonus rate. Can be simple or compound. | Usually paid at maturity or on a death claim. | No |
| Simple reversionary bonus | Calculated only on the original sum assured each year. | At maturity or on a death claim. | No |
| Compound reversionary bonus | Calculated on the sum assured plus previously accrued bonuses. | At maturity or on a death claim. | No |
| Cash bonus | Declared by the insurer and paid directly to the policyholder, often based on the sum assured. | During the policy term. | No |
| Interim bonus | Calculated for the period between the last bonus declaration and the claim or maturity date. | When a claim or maturity occurs between bonus declaration dates. | No |
| Terminal bonus | A one-time additional bonus determined by the insurer for long-standing policies. | At maturity or on a death claim. | No |
| Vested bonus | Represents the total reversionary bonuses already declared and attached to the policy. | At maturity or on a death claim. |
The bonus rate an insurer declares each year isn’t fixed. It changes based on how the participating fund actually performs. Investment returns are the biggest driver. When the fund’s equity and debt holdings do well, more surplus is available to share.
At the same time, mortality experience matters too. If fewer claims are paid out than the insurer expected for that year, the surplus grows. Then, there’s expense management, since a leaner cost base leaves more surplus on the table, and how many policyholders stay invested (persistency) affects the fund’s overall size.
Because all of these shift year to year, insurers do not guarantee bonus rates, and one year’s rate says little about what next year’s will be.
A bonus in life insurance can increase the value of participating policies by allowing policyholders to share in a portion of the insurer’s surplus. The calculation methods and payout timings vary for different types of bonuses in insurance, so it is vital to understand how each one works. Since bonus rates are not guaranteed and may change over time, reviewing the insurer’s past bonus history can provide useful context.
A reversionary bonus is an additional benefit a life insurance company declares on a participating life insurance policy. It is added to the policy benefits. It is not immediately paid to the policyholder but accumulates over time. The payout usually happens at maturity or on a death claim.
A simple reversionary bonus is calculated only on the original sum assured. On the other hand, a compound reversionary bonus is calculated on the sum assured plus previously declared bonuses. It allows the bonus amount to grow faster over time.
A terminal bonus in insurance is a one-time additional bonus. It may be paid upon the maturity of a participating policy or when a death claim is settled. Its purpose is to reward long-term policyholders, and it is not guaranteed.
A vested bonus is the total of all reversionary bonuses that have already been declared and attached to a participating policy. Once vested, these bonuses become part of the policy benefits and are generally payable at maturity or death.
No, not all life insurance policies pay a bonus. They are available only under participating (with-profits or par) life insurance policies. Generally, there are no life insurance bonuses on term insurance plans, ULIPs, and non-participating policies.
A life insurance bonus is commonly calculated using the insurer’s declared bonus rate, the policy’s sum assured, and the number of years for which the policy has been active. The formula for bonus calculation is: Bonus = (Bonus rate per Rs. 1,000 / 1,000) X sum assured X number of years
In most cases, life insurance bonuses are not guaranteed because they depend on the insurer’s surplus and bonus declaration policy. However, once a reversionary bonus has been declared and vested, it is generally payable according to policy terms.
Most bonuses, like reversionary, terminal, and vested bonuses, are held within the policy and paid out together at maturity or when a death claim is settled. A cash bonus is the exception. It's paid to you directly during the policy term, year by year, rather than waiting until the end.
