What is a Cumulative Bonus in Health Insurance?
A cumulative bonus in health insurance is a benefit also called a no-claim bonus. Insurers give this benefit when the policyholder does not make any claims during the policy year.
Depending on the policy terms, the cumulative bonus may increase the sum insured without increasing the premium. Some insurers may also offer a discount on the renewal premium or both benefits together.
A cumulative bonus in health insurance rewards claim-free years. It increases your coverage and helps you manage rising healthcare costs.
How Does Cumulative Bonus Work in Health Insurance?
A cumulative bonus in health insurance increases your cover when you renew after a claim-free year. If you do not make any claims during the policy year, the insurer rewards you by increasing your coverage.
The increase is usually a percentage of the base sum insured. The exact percentage depends on the insurer and the policy terms. It is commonly between 5% and 50% each year.
Most policies also set a maximum limit for the cumulative bonus in health insurance. Many plans allow the bonus to grow up to 50% or 100% of the base sum insured, depending on the policy.
For example, Mr R buys a health insurance policy with a sum insured of ₹10 lakh. His insurer offers a 10% cumulative bonus for every claim-free year, up to a maximum limit of 50%.
- After the 1st claim-free year, Mr R receives a 10% bonus, bringing his total sum insured to ₹11 lakhs.
- After the second consecutive claim-free year, an additional 10% bonus is added, increasing the total sum insured to ₹12 lakh.
- If Mr R does not make any claims for five years, he gets the maximum cumulative bonus in health insurance of 50%. His total cover then becomes ₹15 lakh.
Application of Cumulative Bonus in Mediclaim Policies
A cumulative bonus in health insurance increases your health cover over time without extra premium costs. If you do not make any claims, the insurer rewards you with higher coverage for future medical expenses.
This bonus is useful because it increases your protection every claim-free year. However, if you make a claim, the cumulative bonus in health insurance may reduce.

Types of Cumulative Bonus In Health Insurance
Health insurance companies offer various schemes for cumulative or no-claim bonuses to encourage policyholders to stay healthy and not claim. Understanding these types will help you choose the ideal insurance plan that offers optimum value for money:
- Bonus on Sum Insured
The bonus on sum insured is the most prevalent and advantageous form of cumulative bonuses. Here, the insurance provider increases the sum insured for each year the policyholder has been claim-free, without raising the premium.
For instance, if the initial sum insured was ₹5 lakh and the bonus offered by the insurer was 10%, then:
In the first year, the sum insured would be ₹5.5 lakhs
In the second year, it will increase to ₹ 6 lakh.
The process continues till the maximum possible limit of bonus that can be achieved by the insured person, which normally ranges from 50% to 100%. - Discount on Premium
In this kind of no-claim bonus scheme, the insurer grants the policyholder a discount on the renewal premium instead of adding a percentage to the sum insured. Although this bonus reduces the cost of the insurance annually, it doesn't improve the coverage offered by the policy. This can be fruitful for people seeking reduced renewal premiums. - Bonus as a Fixed Amount
Some insurers offer the cumulative bonus as a fixed monetary amount rather than a percentage bonus. For example, if the insurance company offers a fixed bonus of ₹50,000 for a claim-free year, it will be added to the sum insured if the insured person has not made any claims during that year. - Renewal-Based Bonus
Some insurance companies offer a cumulative bonus in health insurance at the time of policy renewal. The insurer gives this bonus when the policyholder does not make any claims during the policy year.
This benefit encourages people to renew their policies on time and enjoy higher coverage or other rewards. - Family Floater Bonus
In a family floater health policy, all family members share the cumulative bonus in health insurance. If no one makes a claim during the policy year, the insurer increases the total sum insured.
This benefit can be useful for families because it increases coverage without charging an extra premium. - No Claims in Multiple Years Bonus
The Multi-Year No-Claim Bonus is a special type of cumulative bonus in health insurance. Insurers offer it to policyholders who remain claim-free for several years in a row.
Under this benefit, the cumulative bonus in health insurance increases every year if you make no claims.
For example, you may get a 10% bonus after the first claim-free year. After the second claim-free year, it may increase to 20%. After more claim-free years, it can go up to 30% or more.

Factors Affecting Cumulative Bonus in Health Insurance
The cumulative bonus in health insurance depends on several factors that influence the amount a person accumulates. Knowing these factors may help policyholders gain maximum benefits and the advantages of continuous coverage. The key factors affecting the accumulation of bonuses in health insurance are mentioned below:
- Claim History The claim history is highly significant when considering the cumulative bonus. Claim-free years allow an individual to earn higher bonuses. However, regular claims might result in the loss of already-earned bonuses or in their resetting to zero, depending on the insurer’s terms.
- Timely Policy Renewal Renewing your health insurance on time is important to keep the cumulative bonus in health insurance. If you do not renew within the grace period, your policy may lapse. This can also lead to losing all the bonus you have earned so far.
- Terms and Conditions of Insurer The rules for a cumulative bonus in health insurance vary by insurer. The bonus percentage, maximum limit, and impact of claims are not the same in every policy. That is why you should understand these terms before buying a policy. It helps you avoid surprises later.
- Maximum Bonus Limit Most health insurance plans set a maximum limit for the cumulative bonus in health insurance. This limit is usually between 50% and 100% of the base sum insured. Once you reach this limit, you will not get any more bonus, even if you continue to stay claim-free.
- Type of Policy The effect of the cumulative bonus varies between individual health insurance and family floater health insurance plans. This is because the cumulative bonus is applicable only to the insured individual in an individual plan, but is shared among all individuals in the family floater scheme.
- Types of Cumulative Bonus Offered Insurance companies offer different types of cumulative bonus in health insurance. Some increase your sum insured, while others reduce your premium. The way the bonus grows or reduces after a claim depends on the specific policy type.
- Changes in Policy Terms Insurance companies may change policy terms during renewal periods, including the bonus percentage, limits, and claim conditions. These alterations will affect the structure of the cumulative bonus in one way or another.
- Insurance Portability When you port or migrate an indemnity health insurance policy, some benefits can be carried forward. These include the sum insured, no claim bonus, waiting periods, pre-existing disease (PED) waiting period, and moratorium period. This is allowed under IRDAI rules, but it also depends on the new insurer’s terms.

Key Clauses Related to Cumulative Bonus in Health Insurance Policies
A cumulative bonus can add substantial value to your health insurance policy. However, its application and features differ across insurers and plans. The policy requires a thorough understanding before you make your final choice. The key clauses related to the cumulative bonus in health insurance are discussed below:
- Applicable Policy Types: The cumulative bonus is primarily available in indemnity-based health insurance plans, where expenses are covered through reimbursement. However, the plan may not apply to fixed-benefit health plans that offer fixed payment benefits.
- Bonus Percentage and Growth: Most insurers offer a cumulative bonus in health insurance as a percentage increase in your sum insured. This is usually between 5% and 50%, depending on how many claim-free years you complete.
- Maximum Bonus Limit: Cumulative bonus does not increase without limit. The policy specifies the maximum cap, which may be 50%, 100%, or another approved limit of the base sum insured.
- Continuous Policy Renewal: If you renew your policy within the grace period, you keep your accumulated benefits. If you do not renew in time, you may lose continuity benefits and all accumulated credits.
- Impact of Claims on Bonus: If you file for claims during the policy tenure, your bonus may be reduced significantly or even lost. The rate of deduction is usually equivalent to that of the bonus accrued for non-claim years.
- Transferability of Porting: The cumulative bonus can be ported when moving to another insurance provider. It is subject to the portability policy and terms and conditions set by the new insurer.
- Coverage Restrictions: The insurer may impose certain restrictions on the use of the bonus for specific types of coverage. This can include maternity benefits, dental treatment, and cosmetic surgery.
- Suitable for All Policy Categories: Cumulative bonus benefits can be included in both individual and family health insurance policies. Although there might be variations between them.
What is the Difference Between a Cumulative and a No-Claim Bonus?
The terms “cumulative bonus” and “no claim bonus” (NCB) are often used in the same way, but they are slightly different.
A cumulative bonus in health insurance increases your sum insured after each claim-free year.
On the contrary, a no-claim bonus is a discount given on the renewal premium for not making any claims.
No claim bonus (NCB) is often used by insurers to describe cumulative bonus benefits in health insurance. It may increase your coverage, reduce your premium, or offer both. This depends on the policy terms.
How to Check for the Cumulative Bonus Needed for the Health Insurance Plan?
Among the key benefits of health insurance, one is a cumulative bonus. It is essential to know how much additional cover you can get based on the number of claim-free years. Since different insurers have different bonus schemes, reviewing your policy details can make sense. This is how you can check the cumulative bonus in your health insurance plan:
- Examine Your Health Insurance Policy Document This will allow you to review the policy document and learn more about the cumulative bonus. Look out for clauses such as "Cumulative Bonus" or "No-Claim Bonus" to find the percentage and any other conditions related to the cumulative bonus.
- Get in Touch with Your Insurance Company If the policy wording does not provide clarity, contact your insurance company or customer service department for answers. They will be able to tell you more about the percentage, eligibility, maximum amount, and other aspects regarding your cumulative bonus policy.
- Learn About Your Cumulative Bonus Policy Find out whether the cumulative bonus will lead to increased coverage or a reduced premium amount. If your cumulative bonus is 10% on a sum insured of ₹5 lakh, your cover will increase by ₹50,000 if there are no claims.
- Conditions Related to Claims It is also important to understand the relationship between claims and your cumulative bonuses. There is always a possibility of reducing or resetting the cumulative bonuses, based on the terms and conditions set by your insurer, whenever a claim is filed within the policy year.
- Renewal Should be Timely Most insurance companies have a policy that continuous renewals will preserve all accrued bonuses. Failure to do so can jeopardise all the bonuses.
Conclusion: Why Cumulative Bonus Matters
A cumulative bonus in health insurance plans is a significant advantage that rewards policyholders for maintaining claim-free years. It offers them increased coverage without imposing additional premiums.
In the long run, it helps them build stronger financial security amid rising healthcare costs and enhances the value of their plan. Knowing how it works, renewing the plan on time, and avoiding unnecessary claims can help make informed decisions.
