Persistency Ratio (Detailed)
Persistency ratio measures the proportion of insurance policies that remain in force (premiums continue to be paid) at a defined policy anniversary, with the standard measurement cohorts being the 13th, 25th, 37th, 49th, and 61st months, serving as a key indicator of insurer quality and policyholder retention.
Persistency is arguably the most operationally important metric in life insurance, because unlike most financial products, a life insurance policy only fulfils its purpose — providing death cover or maturity benefit — if the policyholder continues paying premiums for the full policy term. Early lapse (discontinuation) destroys value for the policyholder (who typically receives low or no surrender value in the early years) and inflates insurer distribution costs (since upfront commissions have already been paid on a policy that generates no further premium).
IRDAI defines persistency cohorts precisely. The 13th month persistency ratio measures the percentage of policies sold in a given month that still have their premium paid at the 13th month (i.e., after the first annual premium renewal). The 25th, 37th, 49th, and 61st month ratios extend this measurement to the second, third, fourth, and fifth year renewals respectively. Insurers are required to disclose these ratios in their annual reports, enabling cross-sectional comparison.
As of FY2023–24, aggregate industry 13th month persistency was in the 65–70% range for private life insurers, meaning roughly 30–35% of new policies had lapsed within 13 months. The ratio deteriorates progressively: 25th month persistency falls to 55–65%, and 61st month persistency to 45–55% for many insurers. LIC historically reported higher persistency (13th month above 70%) due to its large traditional product mix and agent network's focus on renewal collection.
Low persistency flags potential structural problems: aggressive distributor incentives that reward new business over renewal service; unsuitable product placement (selling high-premium ULIPs to low-income buyers); inadequate post-sale servicing; and economic stress in the policyholder base. IRDAI's guidelines require insurers above certain persistency thresholds to take corrective action, including governance reviews and distribution channel audits.
For equity analysts, persistency improvement drives two financial outcomes simultaneously: renewal premium income (which has near-zero acquisition cost) rises, improving the value of new business (VNB) margin; and the 'persistency strain' — the actuarial reserve release when a policy lapses at a loss — declines, improving embedded value (EV) trajectory. Persistency trends are therefore closely tracked across individual, group, and channel dimensions in insurance company quarterly disclosures.
