Understanding No-Claim Bonus in Health Insurance

What is a No-Claim Bonus (NCB)?

A No-Claim Bonus, commonly known as NCB, is a special reward that your insurer gives you for completing a policy year without raising any claim. It is the insurer’s way of appreciating your good health and responsible use of your health insurance plan.

Instead of losing benefits for not claiming, you actually earn an additional advantage every year you stay claim-free.

In simple terms, NCB increases the overall value of your health insurance policy. When you do not file any claim during the year, the insurer adds a bonus that can come in two primary forms

The customer has the flexibility to choose one of the following benefits:

• Increase in your sum insuredYour coverage automatically increases without any extra cost.
• Discount on your premiumYou may receive a reduced premium at renewal.

Both these benefits make your health insurance no-claim bonus extremely useful in the long run. It helps you gradually build a higher financial cushion for medical emergencies while keeping your health insurance premium more affordable.

Most insurers offer NCB with individual plans, family floater plans, and even top-up plans. However, the percentage of increase, how the bonus accumulates, and the maximum limit allowed depend on the insurer’s rules.

Reading the policy wording carefully helps you understand how the no-claim bonus works in your chosen plan.

How Does No-Claim Bonus Work in Health Insurance?

A No-Claim Bonus (NCB) is applied at the time of policy renewal. Each year that you do not file a claim, your NCB grows. This means you enjoy extra protection without paying extra. The idea is simple: when you maintain good health and avoid unnecessary claims, the insurer rewards you with added benefits.

Here is an easy example to understand how the system works:

• You have a health insurance policy with a base sum insured of ₹5 lakh.
• Your insurer offers 10% NCB for every claim-free year.
• If you do not raise a claim this year, your sum insured increases to ₹5.5 lakh for the next policy year.
• If you again complete the following year without any claims, the coverage increases to ₹6 lakh, and this continues until you reach the maximum limit allowed under your plan.

Some insurers offer a different format in which the NCB is applied as a discount on your renewal premium rather than an increase in the sum insured. In this case, you pay a lower health insurance premium at the time of renewal.

It is important to remember that NCB applies only when no claims are made during the policy year. Even a small claim can reduce or cancel the bonus. However, many modern health insurance policies now include features such as NCB protection or “soft protection,” in which small-value claims do not fully remove the accumulated bonus.

Understanding how NCB works helps you use your no-claim bonus medical insurance wisely and maximise your long-term benefits.

Types of No-Claim Bonus

NCB is not the same across all insurers. Different health plans may offer different types of NCB. Below are the major types:

Benefits of No-Claim Bonus

A No-Claim Bonus (NCB) is one of the most rewarding features offered under health insurance plans. It not only helps reduce long-term costs but also enhances the overall value of your coverage. Instead of losing out during claim-free years, you are given multiple advantages that improve your financial protection and promote better health habits.

Below are the key benefits explained in detail.

Impact of Claims on No-Claim Bonus

The No-Claim Bonus (NCB) is directly linked to your claim behaviour. While it rewards you for maintaining a claim-free year, it can also reduce or reset if you file a claim during the policy year. Most insurers follow a straightforward rule: any claim, even a small one, can affect your accumulated NCB. However, the effect varies across insurers and policy types, so it is essential to understand how your specific health insurance policy treats claims.

Here are the different ways a claim can impact your bonus:

• Complete Loss of NCB: This is the most common and traditional rule. If you raise a claim—whether for a small consultation or a major hospitalisation—your entire NCB may be reset to zero. This means the additional sum insured you have earned over the years is lost, and you revert to the base sum insured at the next renewal.
• Partial Reduction: Some modern policies offer more flexibility. Instead of completely removing the bonus, they reduce it by a certain percentage, usually between 10% and 50%. This method helps protect at least a part of your accumulated bonus, allowing you to retain some additional coverage even after a claim.
• NCB Protection: A few insurers offer an add-on known as NCB Protector, which shields your bonus even if you make one or two small claims in a year. This is useful when minor medical expenses occur, but you do not want to lose your long-term accumulated benefit.

Understanding these rules is essential because your NCB significantly increases your financial protection. Knowing how claims affect your bonus helps you make informed decisions and avoid unexpected reductions in coverage.

Difference Between No-Claim Bonus and Renewal Bonus

Many people confuse NCB with a renewal bonus. Although both are rewards, they are not the same.

The renewal bonus in health insurance is simply a renewal-related benefit, while NCB directly depends on your claims and gives you larger rewards.

How is No-Claim Bonus Calculated?

Insurers calculate NCB as a percentage of your base sum insured. The percentage varies from 5% to 50% per claim-free year, depending on the plan.

Here is a basic formula:

NCB = Base Sum Insured × Bonus Percentage

For example: If your sum insured is ₹4 lakh and your bonus is 20%, then:

NCB = ₹4,00,000 × 20% = ₹80,000

So your total coverage next year becomes ₹4,80,000. You may also use an online no-claim bonus calculator provided by many insurers to estimate future coverage.

Some insurers apply a maximum cap on NCB. For example, your NCB may be limited to 100% or 150% of your base sum insured. After this, even if you do not make claims, it will not increase.

Factors That Affect Your No-Claim Bonus

Several things influence the amount of NCB you can receive. These include:

Things to Check Before Buying a Policy with NCB

When choosing a health insurance plan that includes a No-Claim Bonus (NCB), it is crucial to look beyond the basic features and understand how the bonus is actually applied. Since NCB directly influences your long-term financial protection, evaluating the right factors helps you pick a policy that offers maximum value, stable coverage, and predictable benefits.

Here are the key points to examine before you make a decision:

• Percentage of NCB Offered Every Year: Different insurers offer different NCB percentages. Some provide a fixed 10% increase each year, while others may offer 20–50% based on the policy type. A higher percentage means faster growth of your coverage.
• Maximum NCB Limit: Always check the cap. Many plans allow NCB to accumulate only up to 50%, 100%, or 150% of the base sum insured. If you want more extensive long-term coverage, choose a plan with a higher maximum limit.
• Impact of Claims: Find out whether a single claim results in the complete loss of NCB or just a partial reduction. Some policies reduce the bonus by half, while others may reset it entirely.
• Effect of Small Claims : Some insurers remove the entire bonus even for small claims, while others allow small-value claims without eliminating NCB. This difference matters for families with frequent minor medical needs.
• Availability of NCB Protector Add-On :This add-on safeguards your bonus even if you make one or two claims. It is helpful for people who want predictable coverage without worrying about losing accumulated benefits.
• Effect on Premium :In most policies, an increase in sum insured due to NCB does not raise your premium. Still, it is wise to confirm this with the insurer.
• NCB Rules for Family Floater Policies:In floater plans, a claim by any member can affect the entire family’s NCB. Always review how the insurer handles this.

Evaluating these factors helps you select the best health insurance plan that offers long-term stability and supports your goal to reduce your health insurance premiums while maintaining strong financial protection.
