15 Insurance Industry KPIs Explained - FP&A Professional Institute

Insurance companies live and die by a few numbers.

The same premium dollars that fund claims and operations are also invested to generate additional profits. Tracking the right key performance indicators gives finance, FP&A, and actuarial teams a clear picture of underwriting quality, customer behaviour, operational efficiency, and long-term financial strength.

The most reliable insurance decisions come from understanding how each KPI maps to the insurance system and using them together to answer core questions:

Are we pricing risk correctly?
Are claims trending in a dangerous direction?
Is our book profitable over time?
Are customers staying?

How insurance companies operate (the three engines)

Underwriting and risk selection Evaluate applicants, price policies, and accept or reject risk. Important KPIs here measure claims, frequency, severity, and underwriting profitability.
Customer lifecycle Policy distribution, sales, renewals, and claims handling. KPIs here track retention, acquisition cost, lapses, and customer satisfaction.
Investment of premium float Premiums sit on the balance sheet until claims are paid and are invested across bonds, equities, and long-term assets. KPIs here reveal return on invested assets and capital adequacy.

Top 15 Insurance KPIs every FP&A analyst, Actuary, and Insurance leader should Master

1. Loss ratio

Loss Ratio = Claims Incurred / Premiums Earned

Measures the portion of premiums paid out as claims. A rising loss ratio signals the need for pricing action or tighter underwriting. For FP&A, it is the primary indicator of underwriting performance before expenses.

2. Expense ratio

Expense Ratio = Operating Expenses / Premiums Earned

Shows operating cost efficiency relative to premium income. High expense ratios point to inefficient processes or expensive distribution channels and reduce underwriting margins.

3. Combined Ratio

Combined Ratio = Loss Ratio + Expense Ratio

A combined ratio below 100% means underwriting profit; at or above 100% the company is underwriting at a loss (before investment income). It gives a clean view of insurance profitability excluding investment returns.

4. Premium Growth

Track growth in gross written premium (GWP) or net written premium (NWP) over time. Premium growth is the clearest signal of sales momentum and market share gains. FP&A uses it to validate new business pipelines and scale decisions.

5. Retention Rate (Policy Renewal Rate)

Retention Rate = Renewed Policies / Policies up for Renewal

Renewals are typically more profitable than new business. Higher retention boosts customer lifetime value and reduces the pressure on acquisition spending.

6. Claims frequency

Frequency = Number of Claims / Total Number of Policies

Frequency provides early signals on pricing adequacy and risk quality. An uptick suggests a change in risk mix or customer behaviour that requires fast response.

7. Claims severity

Severity = Total Claim Cost / Number of Claims

Severity captures the average cost per claim. Even with stable frequency, rising severity can quickly erode margins and often reflects inflation, repair cost increases, or more complex claims.

8. Solvency ratio

Solvency Ratio = Available Capital / Required Capital

Measures the ability to meet long-term obligations and is a regulatory cornerstone. A weak solvency ratio may force capital injections or portfolio restructuring.

9. Embedded value growth

Embedded value represents the present value of future profits plus adjusted net worth. Tracking its growth is critical in life insurance to measure the long-term value being created beyond current-year earnings.

10. New business margin (NBM)

New Business Margin = New Business Profit / Present Value of New Business Premium

NBM evaluates the profitability of newly sold contracts. It helps decide which products, channels, or segments deserve scaling and which need redesign.

11. Combined operating ratio (COR)

Similar to the combined ratio but often expanded with additional operating items for a fuller view of underwriting sustainability. COR is commonly used in European reporting and gives deeper insight into recurring underwriting performance.

12. Customer acquisition cost (CAC)

CAC = Total Acquisition Cost / Number of New Policies Sold

CAC measures growth efficiency. Rising CAC extends payback periods and reduces lifetime profitability. FP&A must balance CAC against expected customer lifetime value.

13. Policy lapse / Surrender rate

Lapse Rate = Policies Lapsed / Total Active Policies

A high lapse rate signals product mismatch, poor engagement, or inadequate value perception. Lapses hit long-term revenue and can distort mortality or persistency assumptions.

14. Investment yield

Investment Yield = Investment Income / Investment Assets

Insurers manage large asset pools; even small changes in yield have outsized effects on overall profit. Investment yield links balance sheet management to underwriting results.

15. Net Promoter Score (NPS)

NPS = % Promoters – % Detractors

NPS predicts renewals, upsell potential, and organic growth through referrals. High scores correlate with stronger retention and lower acquisition pressure.

How FP&A uses these KPIs together

These KPIs should not be read in isolation. FP&A teams combine underwriting metrics with customer and investment metrics to answer strategic questions:

Are current prices and underwriting rules sustainable given frequency and severity trends?
Is growth profitable after accounting for CAC and expense ratios?
Does the balance sheet support expected claim volatility and long-term guarantees?
Which products and channels drive the best lifetime margins?

Consistent tracking enables early intervention: tightening underwriting, redesigning products, optimizing distribution, or reallocating investments.

Quick recap by category

Underwriting health: Loss ratio, Claims severity, Claims frequency, Combined ratio
Customer health: Retention rate, Lapse rate, NPS, CAC
Financial strength: Solvency ratio, Embedded value growth, Investment yield
Growth & competitiveness: Premium growth, New business margin, Combined operating ratio

FAQ’s

Q1. Which KPI is most important: loss ratio or retention rate?

Both are critical but serve different purposes. Loss ratio shows current underwriting performance while retention rate indicates future revenue stability and lifetime profitability. Prioritize whichever KPI is causing your current business pain, but track both together for a balanced view.

Q2. How often should these KPIs be reported?

Reporting cadence depends on volatility. Underwriting metrics like frequency and severity should be monitored monthly. Expense, solvency, and embedded value can be managed quarterly, with strategic reviews annually. High-frequency dashboards help detect trends early.

Q3. How does investment yield affect underwriting decisions?

Investment yield supplements underwriting profits. Strong yields can absorb underwriting weakness in the short term, but sustainable underwriting profitability is necessary for long-term stability, especially when yields decline. FP&A needs joint scenario planning for underwriting and investment shocks.

Q4. Can a company be profitable with a combined ratio over 100%?

Yes, if investment returns are strong enough to offset the underwriting loss. However, relying on investment income to cover persistent underwriting deficits is risky and not a viable long-term strategy.

Q5. What KPI should I watch first after a sudden rise in claims?

Start with claims frequency and severity to understand whether more policies are filing claims or the average claim cost is rising. Then check loss ratio and reserve adequacy to assess immediate financial impact and required pricing or underwriting actions.

Final note

Mastery of these 15 KPIs gives finance teams a powerful toolkit to protect margins, steer growth, and maintain capital strength. Use them consistently, combine them in scenario models, and align operational initiatives to the signals they provide.
