Before buying an Indian health-insurance policy advertised with an “automatic cover increase,” identify exactly what increases, when it becomes available, what happens after a claim, and whether the benefit survives renewal. The phrase can describe a cumulative or no-claim bonus, an inflation-linked increase, or restoration (recharge) of exhausted cover. Those mechanisms are not interchangeable.
Read the current policy wording, schedule and endorsements—not just a brochure headline. Confirm the insurer, product name, UIN and policy-period start date, then test the benefit against the claims your household is most likely to make. The steps below are designed for prospective individual and family-floater buyers in India.

Why “automatic increase” is not a sufficient description
A policy’s base sum insured is the underlying amount shown in the schedule. An advertised increase may add to that amount, create a separate bonus balance, or make another pool available only after qualifying exhaustion. A headline such as “cover grows every year” does not tell you which of these has been promised.

Those details are contractual and differ by product.
#1 Best Overall
Separate the following three ideas before comparing policies:
| Mechanism | What changes | Typical trigger to verify | What it is not |
|---|---|---|---|
| Cumulative or no-claim bonus | An added or increased sum-insured amount, often tracked as a bonus balance | Claim-free year, renewal, or another condition specified in the wording | Not automatically an unlimited increase in the original cover |
| Inflation-linked increase | A scheduled increase tied to an inflation measure, such as a specified consumer-price index | The index calculation and continued renewal of the relevant benefit | Not necessarily a reward for being claim-free |
| Restoration or recharge | Additional cover that becomes available after qualifying exhaustion | Exhaustion of stated cover, claim-order rules, illness rules and frequency limits | Not the same as increasing the base sum insured for every claim |
A policy can contain more than one mechanism. Treat each as a separate benefit with its own trigger, calculation, limits and expiry.
Check how the increase is calculated
Identify the calculation base
Ask whether the percentage applies to the original base sum insured, the renewed base amount, the accumulated balance, or another figure. A 20% increase on a ₹10 lakh base is ₹2 lakh; a 20% increase on a ₹14 lakh accumulated amount is ₹2.8 lakh. Those are materially different results.
Ask the insurer to show the calculation in writing for your proposed base cover. If the wording uses several terms—“base sum insured,” “cumulative bonus,” “total sum insured” or “available cover”—request a worked example that identifies which term is used at each step.
Determine whether growth compounds
Simple growth applies each year to the same base. Compounding applies the next percentage to an already increased amount. For an illustration only, a 10% annual increase on a ₹10 lakh base produces ₹11 lakh after one year under either method; after two years it is ₹12 lakh with simple growth on the original base, but ₹12.1 lakh if the second 10% is applied to the increased amount. The policy wording, not the advertisement, determines which method applies.
Find the maximum cap
Every claimed percentage should be read with its ceiling. The cap may be expressed as a multiple or percentage of the base sum insured, a rupee amount, or a limit on the combined base-and-bonus total. Confirm whether the cap applies to the bonus alone or to all available cover. Once the cap is reached, ask whether later claim-free renewals add nothing further or merely preserve the balance.
Read the claim adjustment clause
A claim can leave an accumulated bonus unchanged, reduce it partially, remove it entirely, or trigger a different adjustment at the next policy-year start. Find the exact timing: during claim settlement, at renewal, or when the following period begins. Also check whether the rule differs for a small claim, a claim by one family member, or multiple claims in the same year.

Check renewal continuity
Many bonuses require renewal without a break. Confirm the grace-period treatment, the date by which premium must be received, and whether a lapsed policy restarts the balance. IRDAI guidance treats coverage as unavailable for a period for which no premium is received; do not assume that a grace period preserves every optional benefit. Obtain written confirmation of what happens if payment is late, portability is exercised, or the base product changes.
Understand restoration before counting it as extra cover
Restoration (also called recharge) is generally conditional cover that becomes available after qualifying exhaustion. It may be useful for a second admission in the same policy year, but it does not necessarily enlarge the cover available for the first claim.
When does restoration start?
Look for the precise exhaustion test. Some wordings require the base sum insured to be fully used; others may require the base plus an accumulated bonus to be exhausted. “Exhausted” can mean paid claims, approved claims, or liability incurred, depending on the contract. Ask whether partial use creates any restored amount or whether the trigger requires complete depletion.
Can it pay the first claim?
Do not assume a restoration benefit is available from the first rupee of the policy year. The wording may reserve restoration for a subsequent claim after the initial cover is exhausted. Ask the insurer to illustrate two claims in one year: one that uses the base amount and a second that would rely on restoration.

Check illness and admission restrictions
Restoration may be limited to an unrelated illness, or it may cover the same illness, complications or a repeat admission only under specified conditions. Read definitions of “same illness,” “related illness,” “consecutive hospitalization” and “complication.” If the wording is unclear, obtain a written answer rather than relying on a sales explanation.
Check frequency, floater use and expiry
Confirm how many times restoration can trigger in a policy year, whether it can be used by any member of a family floater, and whether an unused restored amount carries forward. A benefit can be generous in a headline but narrow if it is once per year, restricted to one insured person, or expires at year-end. Restoration is normally tied to the policy period; verify the exact expiry rule.
Keep base cover, bonus and restored cover separate
Ask for a claim-payment sequence. A policy may use the base sum insured first, then an accumulated bonus, and only then restoration. Another wording may combine amounts differently or impose sub-limits on one layer. A combined figure shown in a comparison chart therefore may not be available for every treatment or every admission.
Request a written answer to these questions:
- Which pool pays first?
- Is the bonus available for the first claim of the year?
- Must both base cover and bonus be exhausted before restoration?
- Are room-rent limits, disease sub-limits, deductibles or co-payments applied separately to each pool?
- Does one member’s claim reduce the amount available to other members in a family floater?
Use the answers to model your likely claim pattern rather than adding the displayed amounts together.
Family-floater questions that change the value of an increase
In a family floater, the sum insured is usually a shared pool. Verify whether the automatic increase is also shared, whether one person can consume the entire bonus or restoration amount, and whether the rules change when a member is removed, added, reaches an age limit or migrates to an individual policy.
Ask for scenarios involving two claims in the same year—for example, a parent’s hospitalization followed by a child’s admission. Find out whether the first claim reduces the bonus available to everyone, whether restoration can be used by the second claimant, and whether an illness restriction applies across members. A benefit that looks ample for one claimant may be inadequate when the pool is shared.
Confirm premium, renewal and continuity costs
An automatic increase does not guarantee an unchanged premium. Check the quote and schedule for the rider or add-on charge, whether that charge is annual, and whether the insurer can revise it at renewal under the contract. Distinguish a cumulative bonus granted without an associated premium increase—as defined by IRDAI—from a separately priced rider that contains several benefits.
Verify that the increase option is actually selected and shown in the schedule. If the policy is renewed without the rider, an accumulated benefit may lapse. Check the consequences of changing the base product, moving between individual and floater cover, porting to another insurer, or allowing a break in coverage. Coverage is not available for periods for which no premium is received.
Use the current policy wording, not an older brochure
Match four identifiers before relying on any clause:
- The insurer’s legal name.
- The exact product name and version.
- The Unique Identification Number (UIN).
- The policy-period start date shown on the schedule or certificate.
HDFC ERGO’s policy-wording index is an example of why these identifiers matter: its documents are organized by product, UIN and policy-period start date. Use the equivalent current document supplied by the insurer you are considering. A general brochure, comparison website or earlier wording may not govern the policy offered to you.
Rank #4
Read the schedule, policy wording, endorsements and prospectus together. If they conflict, ask the insurer which document controls and request the answer in writing.
Product-specific illustration: Zurich Kotak Health Protect Rider
Zurich Kotak General Insurance Company’s Health Protect Rider policy wording identified as ZK-v1 (24-25), UIN ZUKHLIA23111V022223, bears a September 30, 2024 date in its filename. It illustrates why the benefit names must be separated. Verify that this product and wording are currently offered and applicable before treating any of these terms as available to you.
| Benefit in the cited rider | What the wording describes | What you still must verify |
|---|---|---|
| Inflation Protect | Increases linked to the prior year’s consumer-price index; the increase applies to the base sum insured, not to cumulative bonus or other benefits. | The current index formula, cap, amount for your policy and whether the rider is renewed. |
| Super NCB | Requires no claim in the expiring policy year and renewal without a break; provides a specified cumulative increase subject to a cap; a claim reduces the accrued amount at the next policy-year start. | The percentage, cap, claim calculation and whether your schedule includes the option. |
| Restoration Benefit Plus | Contains conditions concerning qualifying exhaustion, first-claim availability, related illness and expiry; unused restored cover does not carry forward. | How many triggers are allowed, which claims qualify and how the rule operates for a floater. |
The rider can be bought only with the base product and only when reflected in the schedule. Its terms are an example of one insurer’s wording, not a market-wide rule. Do not generalize its conditions to another policy.
A written-question checklist for the insurer or intermediary
Ask the following questions and keep the answers with your quotation:
- What is the formal name of the automatic-increase benefit?
- Does it increase the base sum insured or create a separate bonus or benefit pool?
- What is the calculation base: original base, renewed base or accumulated balance?
- Is the increase simple or cumulative?
- Is it guaranteed each policy year, or only after a claim-free year and uninterrupted renewal?
- What is the cap, and is it calculated from the base sum insured or the total available cover?
- After a claim, is the accumulated amount unchanged, partially reduced, fully reduced or recalculated?
- For restoration, must the base and bonus both be exhausted?
- Can restoration pay the first claim, the same illness, a complication or a repeat admission?
- How many times can restoration trigger, and when does unused restored cover expire?
- For a floater, is the increase shared, and what happens if a covered member changes?
- What is the rider premium, can its renewal terms change, and is the option shown on the schedule?
- How do waiting periods, exclusions, co-payments, deductibles, room restrictions and disease sub-limits apply to the increased amounts?
- Do the product name, UIN and policy-period start date match the wording supplied for purchase?
How to compare two policies without being misled by percentages
Build a side-by-side comparison using the same base sum insured and the same household scenario. Record each item below; a larger percentage is not automatically better.
| Comparison axis | Questions to record |
|---|---|
| Increase mechanism | Cumulative bonus, inflation link, restoration, or a combination? |
| Calculation | What is the base, and does the amount compound? |
| Cap | What is the maximum rupee or percentage amount? |
| Claim impact | What happens after one claim or several claims? |
| Qualification | Is a claim-free year or uninterrupted renewal required? |
| Restoration | What exhaustion, illness, first-claim and frequency rules apply? |
| Floater treatment | Who can use the amount, and is it a shared pool? |
| Expiry | Does unused bonus or restoration carry forward or lapse? |
| Cost and renewal | What is the rider premium and what can change at renewal? |
| Version control | Do the insurer, product, UIN and policy-period documents match? |
Compare ordinary coverage limits separately. Waiting periods, exclusions, co-payments, deductibles, room eligibility and disease-specific limits can affect a claim more than an advertised increase.
Common mistakes and how to avoid them
Counting restoration as permanent cover
Fix: model the first and second claims separately and identify the exhaustion trigger. Do not add restored cover to the base amount as though it were available from day one.
Best Value
- It can be a gift option
- Comes with secure packaging
- Helpful in various ways
Assuming “automatic” means unconditional
Fix: locate requirements for a claim-free year, renewal without a break, rider selection and premium payment.
Using a percentage without its base
Fix: write the rupee calculation for your own base sum insured and ask whether the percentage compounds.
Ignoring a claim reduction at renewal
Fix: ask exactly when and how the bonus is recalculated after a claim.

A practical decision test before you pay
- Write down the base sum insured needed for one serious hospitalization in your city, without counting any bonus or restoration.
- For each policy, calculate the amount available for a first claim, a second claim after exhaustion and a claim after one prior-year claim.
- Apply the policy’s waiting periods, exclusions, co-payments, deductibles and room limits to those scenarios.
- Check the premium with and without the increase option and record renewal conditions.
- Reject any option for which the insurer will not identify the governing wording, UIN, trigger, cap or claim sequence in writing.
Choose the policy whose contractual claim path fits your household, not the one with the largest promotional percentage.
The Bottom Line
Buy an automatic-increase policy only after you can state, in rupees and in writing, how the base cover, bonus and restoration would respond to your first and subsequent claims under the current policy wording.
