How Much Health Insurance Do I Need? Why ₹5 Lakh Rarely Covers a Family Today

How much health insurance do you need?

Use this table as a starting point. These are general guidelines, not fixed rules. The five steps below will help you calculate a suitable amount for your family.

These rules don’t necessarily reflect what your family might spend on treatment. A better approach is to start with actual hospital costs.

Why does ₹5 lakh rarely cover a family today?

Medical expenses in India have been rising faster than many everyday household costs. WTW’s 2026 Global Medical Trends Survey projects India’s medical costs to increase by 12.9% in 2026.

This is medical inflation: the same surgery or treatment costs more as time passes. If hospital costs rise by 12% annually:

• A hospital bill of ₹5 lakh today could reach approximately ₹8.8 lakh in five years.
• The same bill could rise to around ₹15.5 lakh in ten years.

Think about how much school fees have compounded over the past decade. Medical expenses can put similar pressure on your family’s finances.

There is another problem with a family floater, where all covered family members share one sum insured.

If one person needs expensive treatment early in the year, less cover remains for everyone else. A single major hospitalisation can exhaust a ₹5 lakh floater.

How to work out your family’s health cover in 5 steps?

Step 1: Estimate the cost of one major hospital stay

Start with the hospital you would choose for serious treatment, such as heart surgery. Ask its billing department or your family doctor for an estimate that includes a few days in the intensive care unit (ICU).

Step 2: Account for a second claim in the same year

Your family may need hospital treatment more than once a year. If a major hospital stay costs ₹8 lakh, add another ₹2 lakh for a smaller admission, such as a child’s hospitalisation for dengue. Your estimated requirement is now ₹10 lakh.

Step 3: Allow for five years of medical inflation

Increasing your sum insured later may require fresh medical disclosures, and waiting periods may apply to the additional cover.

Assuming medical inflation of 12% annually, multiply your step 2 amount by approximately 1.76. In this example, ₹10 lakh becomes around ₹17.6 lakh.

Step 4: Count only the cover you control

Your employer’s health insurance may end when you change jobs, take a career break or retire. Don’t subtract it from the amount you need independently. Treat it as additional protection while it is available.

Step 5: Combine a base policy with a super top-up

Choose a base policy that can handle a major hospital stay at today’s prices. Add a super top-up with a deductible matching your base cover and enough additional protection to take your total cover beyond the amount calculated in step 3.

Your step 3 figure is the minimum target based on these assumptions. A higher amount may be appropriate for expensive or prolonged treatment, such as cancer care.

Why income-based thumb rules can mislead you?

Rules such as buying health insurance worth half your annual income or one to three times your income are easy to remember, but they don’t necessarily tell you how much cover you need.

A family earning ₹8 lakh a year and another earning ₹60 lakh could face the same hospital bill for the same surgery at the same hospital. Treatment costs don’t automatically change with your income.

Use your income to decide how much premium you can comfortably afford. Base the sum insured primarily on your family’s medical needs and the cost of treatment you want to prepare for.

Example: Sizing cover for a family of four

Consider Rohan, an illustrative example of a 38-year-old salaried professional in Pune. His wife is 35, and their children are eight and four. His parents, aged 64 and 60, live in Nashik.

Rohan currently has only a ₹5 lakh family floater provided by his employer. Here’s how he can work out his requirement.

All figures are illustrative. Actual hospital costs, policy terms and premiums will vary.

Rohan’s calculated requirement is approximately ₹17.6 lakh. A ₹25 lakh super top-up over his ₹10 lakh base policy would take his total potential cover to ₹35 lakh, already above that estimate.

He chooses a ₹50 lakh super top-up because the additional cover may cost relatively little compared with buying the same amount as a base policy. It also provides more room for a prolonged illness.

His employer’s ₹5 lakh cover remains useful while he is employed. It may help pay smaller claims, depending on the policy terms, but he doesn’t rely on it as part of his long-term protection plan.

His parents need a separate policy for the reasons explained below.

Should your parents be on your family floater?

Usually, it’s better to keep parents over 60 on a separate health insurance policy.

A family floater’s premium depends partly on the age of the oldest insured member. Adding parents in their 60s can increase the premium for the entire family. 

Their medical expenses also come out of the same shared sum insured, potentially leaving less cover for you, your spouse and your children.

Consider one floater for both parents or individual policies, depending on their needs and the insurance company’s terms.

Before buying, keep these points in mind:

• Check the co-payment. This is the portion of an approved claim you must pay yourself. Some senior citizen plans have a 20% co-payment. On an eligible ₹5 lakh claim, that could mean paying ₹1 lakh, subject to the policy terms.
• Understand waiting periods. Pre-existing conditions, including diabetes and high blood pressure, may have waiting periods. IRDAI regulations cap the waiting period for pre-existing diseases at three years.
• Don’t assume age makes insurance impossible. Since April 2024, insurance companies have been required to make health insurance products available without an upper age limit for entry. Acceptance, underwriting terms and premiums still depend on the insurance company and product.
• Check premium increases. Insurance companies cannot increase a senior citizen’s health insurance premium by more than 10% in a year without prior IRDAI approval.
• Review the tax treatment. Under the old tax regime, eligible premiums paid for parents may qualify for a separate deduction under Section 126 of the Income-tax Act, 2025, with a higher limit for senior citizens. Check the applicable conditions and limits.

If you are an NRI paying for your parents’ medical needs in India, choose a policy with a suitable hospital network in their city.

Is your employer’s health cover enough?

For most families, employer-provided health insurance should be additional protection, not their only policy.

Many employers provide cover of ₹2 to 7 lakh, shared with your spouse, children and sometimes parents. The problem is that the policy is linked to your employment. It may end when you change jobs, take a break or retire, when buying a new policy could be more expensive.

Two steps can help:

• Maintain a personal base policy. Buying your own cover while you’re relatively young and healthy allows you to complete applicable waiting periods before you need to claim.
• Explore migration before leaving your job. IRDAI’s framework allows eligible members of group health insurance schemes to seek migration to an individual or family policy with the same insurance company, subject to applicable conditions. Credit for waiting periods already served may carry forward, but acceptance and terms aren’t guaranteed. The insurance company may require medical assessments, and credit may be limited to the eligible existing cover. Start early, ideally 30–60 days before leaving, and confirm the insurance company’s requirements.

One mistake to avoid is buying a super top-up with a ₹5 lakh deductible and assuming your employer’s ₹5 lakh policy will always cover the first layer.

If you leave your job and lose that cover, you may have to pay the first ₹5 lakh of eligible medical expenses yourself before the super top-up starts paying.

Anuj says, “I look at company health insurance as a benefit that adds to your protection while you’re employed, not as a substitute for a policy of your own. Your personal policy should be the foundation of your plan, with applicable waiting periods already served. A job change or retirement can leave you needing cover when buying a new policy may be more difficult or expensive. Planning early can help you avoid that situation.”

How does a base plan and super top-up work together?

A base health insurance policy pays eligible hospitalisation expenses from the first rupee of an approved claim, subject to the sum insured and policy conditions.

A super top-up provides additional cover once your total eligible medical expenses during a policy year cross a specified amount called the deductible. Since it covers expenses beyond this initial threshold, it can be more affordable than buying a very large base policy.

A regular top-up works differently. It generally checks whether each individual hospital bill crosses the deductible, while a super top-up considers the total eligible expenses during the policy year.

This Outlook Money explainer provides further context.

Consider Rohan’s setup again: a ₹10 lakh base policy and a super top-up with a ₹10 lakh deductible.

Suppose his family has two hospital stays in the same policy year, costing ₹6 lakh and ₹9 lakh. For this illustration, assume the base policy has no restoration benefit, which would otherwise replenish the sum insured after a claim.

All figures are illustrative and assume the expenses are eligible under the policies, with no other limits or exclusions affecting the claims.

Match the deductible to your base cover to avoid a gap that you would have to pay yourself. Also check room rent restrictions, co-payments, waiting periods and claim conditions under both policies.

Don’t rely on restoration as a substitute for sufficient cover. It may replenish your base sum insured after a claim, but it may not help when a single hospital bill exceeds your base cover.

Anuj says, “People sometimes ask why they shouldn’t simply buy a ₹1 crore base policy and avoid worrying about cover altogether. You can consider that option, but you’ll pay a higher premium for a large amount of base cover you may rarely use.”

Where does critical illness cover fit?

Regular health insurance pays eligible hospitalisation expenses. Critical illness insurance serves a different purpose: it pays a lump sum if you’re diagnosed with a specified illness covered by the policy, such as certain cancers, a heart attack or a stroke.

You can use this money for expenses beyond the hospital bill. A serious illness may keep you away from work for months, require home care or involve travel and other recovery costs that your health insurance may not cover.

Before buying, check two important conditions:

• Survival period: The number of days you must survive after diagnosis for the benefit to become payable. Some policies specify around 30 days.
• Initial waiting period: The period after buying the policy during which specified diagnoses may not qualify for a payout. This is often around 90 days, depending on the policy.

Read the definitions of covered illnesses carefully. Not every condition or stage of a disease necessarily qualifies.

You may buy critical illness cover as a rider, or add-on, to a term life insurance policy or as a separate policy.

How much cover should you consider? Base it on the income you could lose during treatment and recovery, along with your family’s additional expenses.

It can be particularly useful if you are the family’s only earning member, are self-employed without paid sick leave or have a family history of serious illness.

6 mistakes that could leave you under-insured

1. Choosing cover based only on the premium. A cheaper policy may have a lower sum insured, co-payment or room rent restriction. Compare what the policy pays, not just what it costs.
2. Counting employer cover as your own. Your company policy may end when you leave the job, potentially when buying new cover is more expensive.
3. Adding parents over 60 to your family floater. This can increase the premium and put the shared sum insured at risk if a parent needs expensive treatment.
4. Ignoring the room rent limit. Choosing a room above the permitted limit may lead to proportionate deductions on associated hospital charges, depending on the policy. A high sum insured doesn’t automatically protect you from this restriction.
5. Relying on restoration or a no-claim bonus. Restoration may replenish cover after a claim, while a no-claim bonus may increase cover over time. Neither replaces an adequate base policy.
6. Never reviewing your cover. Having another child, moving to a bigger city or learning about a parent’s medical condition can change your needs. Revisit your calculation when circumstances change.
