Best Ways to Select the Right Sum Insured for Your Health Insurance Plan

The sum insured in health insurance is the maximum amount that the insurance company will pay you during a medical emergency if you are hospitalised within a certain year.

In simple terms, if you buy a health insurance plan with a ₹10 lakh sum insured, the insurer will cover eligible expenses up to ₹10 lakh in a year, including hospitalisation, treatments, and other covered costs.

You are responsible for paying out of pocket any excess over the insured amount. However, the insurance company will cover the full cost if the hospitalisation or expenses are less than or equal to the covered amount.

To choose the right sum insured in health insurance, pick a coverage amount that can handle major expenses based on your risk profile, city, and rising health treatment costs. Choosing too low a sum insured can lead to high out-of-pocket expenses during emergencies, even if you have insurance.

To select the right sum insured in health insurance, follow these three easy steps:

Step 1: Assess Your City Health Care Expenses

Assessing the cost of healthcare in your city is the first stage. Find out the typical healthcare cost in your state or city to get an idea of what you could have to pay. This may cover the price of hospital stays, operations, and therapies. Additionally, you would have to account for the price of consultations, prescription drugs, and diagnostic testing. 

If you live in a metro or Tier 1 city, treatments can be 15 - 60% more expensive compared to smaller cities (2). Your sum insured should be high enough to cover private or government hospitalisation costs in your area, not just average estimates. This will prevent unforeseen out-of-pocket spending. 

Step 2: Evaluate Your Health Risks and Needs

Assessing your healthcare demands and risks are the next step in determining the sum insured:

• To determine possible health risks and costs, take into account your age, lifestyle, and medical history.
• Your lifestyle choices, such as smoking or not exercising, can also raise your risk of developing diseases, including cancer, diabetes, and heart disease.
• As you age, the probability of hospitalisation and critical illnesses increases. If you’re:

✓ Under 30 → Lower risk but rising future costs

✓ 30 - 50 → Increasing lifestyle-related risks (diabetes, BP, etc.)

✓ 50+ → Higher likelihood of frequent and expensive treatments

Hence, the higher the health risk and age, the higher the sum insured to cover the expenses. 

Step 3: Consider Your Family Size

If you are buying a family floater plan, the sum insured is shared among all members. While this makes premiums more affordable, it also increases the risk of coverage getting consumed faster, especially in larger or high-risk families. 

This means that one major claim can reduce coverage for everyone else, and multiple claims in the same year can exhaust the policy faster. Therefore, opt for a higher sum insured if multiple members are covered under one plan or consider getting separate policies for elderly members. 

Step 4: Consider Medical Inflation

Medical inflation in India is rising at an alarming rate, often higher than general inflation. Healthcare costs, including hospitalization, doctor consultations, diagnostic tests, and medicines, are increasing every year. A treatment that costs ₹5 lakh today might cost ₹15 - 20 lakh in the next 10 years.

Hence, it is important to choose a sum insured considering medical inflation. Here are some ways you can consider:

• If you need ₹5-7 lakh coverage today, opt for at least ₹15-25 lakh to stay covered for the future.
• Look for super top-up plans to enhance your coverage without a massive increase in premium.
• Choose insurance policies with a no-claim bonus. Some insurance companies may increase your sum insured for every claim-free year.

Step 5: Balance Premium, Your Financial Capacity and Coverage

While choosing the right sum insured, it’s important to find a balance between affordability (premium) and adequate coverage. A higher sum insured offers better protection but comes with a higher premium.

At the same time, your decision should depend on your income and savings, because if your income is limited, even a small amount of uncovered expenses can create financial stress during a medical emergency.

Here are some factors you must consider having right balance between premium & coverage:

1. Assess your budget
2. Opt for a top-up plan
3. Look for no-claim bonuses (NCB)
4. Compare policies from different insurers
5. Consider co-payment & deductibles in health insurance

Step 6: Evaluate and Select the Appropriate Sum Insured

The last step is to compare and select the sum insured for your health insurance plan. To pick a plan that suits your demands and budget, compare the possible costs and expenses of healthcare with several alternatives for the sum insured. 

Lastly, consider each plan's coverage features and exclusions to ensure sufficient coverage for your medical needs. 

Maximising your sum insured means increasing your effective coverage smartly so that you are protected against large expenses without increasing your financial burden. You can do this by:

Adding a Super Top-Up Plan to Base Plan

A super top-up plan is one of the most effective ways to increase your overall coverage. It comes into effect only after your base policy limit is exhausted, allowing you to get ₹20 - ₹50 lakh extra coverage at a relatively low cost. This is especially useful for handling high-value claims like surgeries or critical illnesses.

Take Advantage of No Claim Bonus (NCB)

Many insurers reward you for not making claims by increasing your sum insured every year. Over time, this can significantly boost your coverage. Choosing a plan with cumulative bonus benefits helps you build a higher safety net for the future.

Choose a Plan with Restore or Refill Benefits

Some policies offer a restoration benefit in health insurance, which automatically restores your sum insured if it gets exhausted during the policy year. This ensures that you are still covered for multiple or repeat hospitalisations, which is crucial for families or during long-term treatments. 

For example: If your ₹10 lakh sum insured is fully used for one surgery, the restoration benefit can refill it back to ₹10 lakh. This means you’ll still be covered if another hospitalisation happens in the same year for any other treatment. 

Choosing the right sum insured is about making a financial decision that protects you from unexpected expenses without straining your savings. The right coverage should be decided depending on your city, age, health risks, family size, and income, while also accounting for rising medical costs over time.

At the same time, choosing the right sum insured doesn’t mean overspending. You can optimise your coverage by using tools like super top-up plans, no claim bonuses, and restoration benefits, ensuring you get higher protection without paying disproportionately higher premiums.
