What is a loss ratio and how does it affect renewal pricing?

Loss ratio is the ratio of claims paid (plus claims reserved for future payment) to premium collected in a policy year, expressed as a percentage. For a group health insurance policy, a loss ratio below 80% is generally considered profitable for the insurer, and a loss ratio above 100% means the insurer paid out more in claims than it received in premium. Loss ratio is the single most important input into how the insurer prices the renewal.

How is loss ratio calculated?

Loss ratio is calculated as:

Loss ratio = (Incurred claims / Earned premium) x 100

Incurred claims include claims paid during the policy year plus claims reserved for known but unpaid future claims (called IBNR: incurred but not reported reserves). Earned premium is the premium the insurer has recognised as revenue during the year, net of GST. Both numbers are typically taken from the insurer's claim register and shared with the employer or broker at the point of renewal.

What is a healthy loss ratio for a group policy?

A loss ratio between 60% and 75% is a healthy range. This means:

• The employer is getting good value: employees are actually claiming and using the cover.
• The insurer is making a reasonable margin after paying claims and administrative costs.
• The renewal premium is likely to increase in line with medical inflation (10% to 15%), not substantially more.

A loss ratio below 60% signals underutilisation, and above 80% signals the insurer needs to reprice.

How does loss ratio affect renewal pricing at different levels?

• Below 60%: Employer has room to negotiate. Insurer may hold premium flat or offer a small decrease.
• 60% to 75%: Renewal typically at inflation-linked increase (10% to 15%).
• 75% to 90%: Renewal at a higher increase (15% to 25%), with possible plan design nudges.
• 90% to 100%: Substantive premium increase (25% to 40%), and insurer typically pushes for design changes (higher co-payment, room rent sub-limits, exclusions).
• Above 100%: Premium increase can exceed 50% in extreme cases, and the insurer may decline to renew without meaningful design changes.

What drives a high loss ratio?

Common drivers of a high loss ratio in a group policy include:

• High parental utilisation: Parents typically claim more than employees, and heavy parental utilisation drives up total claims.
• Concentrated high-cost claims: A few very large claims (Rs 10 lakh plus) in a small pool can push the ratio above 100%.
• Maternity concentration: A workforce with a high proportion of maternity claims relative to the policy's maternity sub-limits.
• Chronic condition claims: Regular claims for dialysis, oncology, or cardiac care from a small number of members.
• Overuse of premium hospitals: High utilisation at top-tier hospitals where cash rates are meaningfully higher.

Can an employer influence the loss ratio during the policy year?

Only partially. Employers can encourage employees to use network hospitals (which have negotiated rates), reduce administrative rejections through better documentation, and communicate policy limits clearly to avoid disputes. However, most claim behaviour is driven by health events that cannot be scheduled. Design changes at renewal (sub-limits, room rent caps, co-payment) are the more common lever than in-year intervention.

How Plum approaches this

Plum shares the loss ratio breakdown with the employer 90 days before renewal, along with an analysis of what is driving the ratio (parental cover, specific claims, hospital selection) so the employer can consider design changes with data in hand rather than reacting to the insurer's quote. Across Plum's group book, claims NPS runs at 79 and cashless pre-authorisation clears in a median of 45 minutes, and these service metrics sit alongside loss ratio in renewal conversations. Plum places group cover from a minimum of 7 employees, working with partner insurers including ICICI Lombard, HDFC ERGO, Bajaj Allianz, Star Health, Niva Bupa, and Aditya Birla Health Insurance, and runs fresh quotes to pressure-test whether the incumbent insurer's quote is aligned with market pricing given the loss ratio.

Frequently asked questions

Who calculates the loss ratio?

The insurer calculates it from its claims register. The broker or HR team can request the calculation and audit the underlying claim data.

Does loss ratio include GST?

No. Loss ratio is calculated on net premium (excluding GST) against incurred claims. GST is a separate line item.

What if the loss ratio calculation looks incorrect?

The employer or broker can request a claim-by-claim breakdown from the insurer and verify against the internal claim log.

Does a high loss ratio mean the insurer will not renew?

Not necessarily. Most insurers renew even at loss ratios above 100%, but with substantially higher premium and plan changes.

Can loss ratio be improved without cutting benefits?

To some extent. Better network utilisation, TPA-managed claim review, and reduced fraud can improve loss ratio without touching cover terms.

Does a low loss ratio mean employees are not using the cover?

It can. A very low loss ratio (under 40%) may indicate poor awareness of benefits or barriers to claim. Employers may want to communicate the cover more actively.
