When you think “established health insurer,” your mind probably doesn’t immediately land on Royal Sundaram. You’re thinking Star Health, HDFC ERGO, Bajaj, or Niva Bupa. Yet Royal Sundaram was the first private general insurance company to get an IRDAI license in October 2000, two decades before many competitors hit the market.
Today, Royal Sundaram operates in a crowded space. Its market share hovers around 1.5% of standalone health insurance, trailing far behind Star Health (32%) and HDFC ERGO (18%). The company serves 4.5+ million customers across all product lines (motor, health, travel, personal accident), not just health. Its financial backing, a joint holding of Sundaram Finance (50%), Ageas (40%), and Indian shareholders (10%), suggests institutional stability. But it doesn’t automatically mean superior claim service.
This review will dig into Royal Sundaram’s performance metrics, product design, real claim experiences, and pricing. Most importantly, it will explain what each number means to your purchase decision.
Key Performance Metrics: What the Numbers Say
| Metric | Royal Sundaram (FY26) | What This Means |
| Claim Settlement Ratio (CSR) | 90.77% | Just above the benchmark of 90%. 9 of 100 claims are not settled |
| Incurred Claim Ratio (ICR) | 79% | Within the healthy range of 60-80% |
| Complaint Volume (per 10,000 claims) | 32.72 | On the higher side, suggests more operational pain points during claims |
| Gross Written Premium | ₹4,638 crores | Much smaller than other old players, indicates limited scale |
| Network Hospitals | 12,500+ | Matches large competitors |

Claim Settlement Ratio
This is the percentage of claims actually settled by Royal Sundaram out of all claims filed in FY26. 91 out of every 100 claims got paid. That’s just above the recommended benchmark of 90%. This sounds reassuring but is significantly below the popular names, like HDFC Ergo, Bajaj General, or Care Health.
What this means: This is the most significant number being the closest proxy of the insurer’s willingness to settle a claim. However, this tells you nothing about a claimant’s experience during the claim process. It doesn’t tell you if the insurer argues over minor points or accepts documentation gracefully.
Incurred Claim Ratio
This is the percentage of premium income that the insurer pays out as claims. Royal Sundaram’s ICR of 79% in FY26 means for every ₹100 in premiums collected, it pays out ₹79 in claims. This sits comfortably within the healthy industry range of 60–80%.
What this means for you: The optimal ICR range is 60–80%. Royal Sundaram’s 79% places it in the sweet spot. It suggests that the insurer is profitably pricing premiums while maintaining genuine claims coverage. This is better positioning than peers operating at 85–90% ICR, who face margin pressure and potential future premium hikes.
Complaint Volume — The Rising Trend
This is where Royal Sundaram’s story becomes problematic. For every 10,000 claims, 32.72 complaints are registered, much above our recommended benchmark of 20. But the real concern is it’s the trajectory:
- FY23: 13.47 complaints per 10,000 claims (good)
- FY24: 17.59 complaints per 10,000 claims (acceptable)
- FY25: 32.72 complaints per 10,000 claims (rising sharply)
What this escalation means: Royal Sundaram is experiencing rapid complaint growth as customer volumes increase. The insurer’s infrastructure — claims processing, customer support, hospital coordination — isn’t scaling smoothly. A big jump in one year (17.59 → 32.72) signals internal strains. Claims might be taking longer with stricter documentation, or pre-authorisation delays might be frustrating customers.
Comparison with other insurers:
- HDFC ERGO: 4.99 complaints/10,000 claims (6.4x lower)
- Bajaj General: 3.07 complaints/10,000 claims (6x lower)
- Star Health: 54.02 complaints/10,000 claims (1.6x higher, but not rising at Royal Sundaram’s rate)
Gross Written Premium (GWP)
Royal Sundaram GWP for the last fiscal year stood at ₹4,638 crores, which is much smaller than any other insurer with such a long track record. Smaller scale may mean fewer publicly available customer experiences and less market presence. Though, scale alone should not be treated as a measure of claim or service quality.
Scale isn’t everything, but it’s one factor you should consider.

Pros and Cons
Strengths
Long Operating History: 25+ years in the market. Established brand. The regulatory track record is clean.
No Room Rent Capping (Mid-Tier+): Most plans have zero room rent restrictions. A premium room in a metro hospital can cost ₹10,000–15,000/day; Royal Sundaram covers actual costs.
Wide Hospital Network: 12,500+ network hospitals across India. Cashless treatment availability is not a bottleneck.
Decent Claim Settlement Ratio: 90.77% is decent and above the benchmark.
Weaknesses
Rising Complaint Volume: Royal Sundaram’s complaints have nearly doubled year-on-year (13.47 → 17.59 → 32.72 per 10,000 claims) and now exceed industry average. This directly signals growing friction in claim settlement.
Small Market Share & Scale: ₹4,638 crores of annual GWP is much smaller for an old general insurance company. Royal Sundaram isn’t a top-of-mind health insurer for most Indians. Online reviews and community feedback are sparse compared to Star Health or HDFC ERGO.
Weak Cumulative Bonus: 20% per annum with max 100% is underwhelming and well below what competitors offer.
Should You Consider Royal Sundaram?
Buy Royal Sundaram only if:
- You are ok with rising complaint volume and can handle claim processing delays or friction.
- You’ve already compared premiums with Royal Sundaram is significantly cheaper.
For most other buyers: Start with HDFC ERGO, Bajaj, or Care Health instead. You’ll pay slightly more, but you’ll get claims processed efficiently.
Strongly consider alternatives if:
- You want fast, friction-free claim processing. Royal Sundaram’s complaint volume is rising sharply (32.72 per 10K, up from 13.47 two years ago). Expect delays and documentation back-and-forth.
- You want the highest claim settlement ratio. HDFC ERGO (98.70%) or Bajaj (96.76%) are objectively better.
- You want a better cumulative bonus structure. Many competitors offer 100% yearly bonus accumulation.
Algates Insurance Verdict
Health insurance is not a purchase you make once and forget. It’s a relationship that matters the most when a crisis hits.
Royal Sundaram is a credible, established insurer with solid fundamentals, but not one we’d recommend by default. It is facing operational stress.

Frequently Asked Questions
Royal Sundaram is a credible health insurer with over 25 years of operating history and a claim settlement ratio of 90.77% in FY26. However, its complaint volume has risen sharply in recent years, suggesting that the claims experience may not be as smooth as some leading competitors. It can be a suitable option in specific situations, but it isn't our default recommendation for most buyers.
Royal Sundaram reported a health insurance claim settlement ratio (CSR) of 90.77% in FY26. This means it settled about 91 out of every 100 claims received. While this is above the 90% benchmark, several leading insurers reported higher settlement ratios during the same period.
Complaint volume reflects how frequently policyholders escalate issues to the regulator or the insurer relative to the number of claims handled. A higher complaint ratio doesn't necessarily mean claims are rejected, but it may indicate greater friction during the claims process. Royal Sundaram's complaint ratio has increased significantly over the past few years, making it an important factor to consider.
The right plan depends on your needs. Lifeline Supreme is suitable for most families looking for comprehensive hospitalisation cover. Lifeline Elite is designed for buyers seeking higher coverage and premium features. Family Plus works well for larger families. Lifeline Multiplier is suitable for those wanting enhanced protection for specified critical illnesses. The best plan is the one that aligns with your medical needs, budget, and existing insurance coverage.
Based on the metrics analysed in this review, HDFC ERGO and Bajaj General currently outperform Royal Sundaram on claim settlement ratio and complaint volume. Unless Royal Sundaram offers a significant pricing or product advantage, many buyers may find these insurers to be stronger overall choices.
Yes. Royal Sundaram has a network of more than 12,500 hospitals across India, which is comparable to many large health insurers. For most buyers, hospital network size is unlikely to be a deciding factor.
Royal Sundaram's premiums are generally competitive for entry-level and mid-range plans. However, higher sum insured options can become relatively expensive compared to some competing insurers. Always compare premiums alongside policy features, waiting periods, and claim experience instead of choosing solely based on price.
Royal Sundaram may be worth considering if: It offers a significantly lower premium than comparable plans. Its features match your specific healthcare needs better than alternatives. You've compared it with similar plans and are comfortable with its recent complaint trend. Who should avoid Royal Sundaram Health Insurance? You may want to consider other insurers if: A consistently smoother claims experience is your highest priority. You're looking for insurers with stronger claim settlement performance. You prefer plans with more competitive cumulative bonus structures.
Royal Sundaram remains a financially stable and established insurer, but it is not our default recommendation for most buyers in 2026. While its products are competitive, the rising complaint volume raises concerns about the overall claims experience. Compare it carefully with leading alternatives before making your decision.
Don't compare insurers based on premium alone. Evaluate: Claim settlement ratio; Complaint volume; Waiting periods; Coverage and exclusions; Restoration and bonus benefits; Network hospitals; Your own medical history and healthcare needs. A policy that is slightly more expensive today can deliver significantly better value when you need to make a claim.
