Measuring Insurance Core Modernization ROI: Metrics and Best Practices

Transformation success must be measured. Boston Consulting Group suggests insurers evaluate core modernization by tracking:

• IT Cost Reductions: Measure lowered IT spend per policy and reductions in unplanned downtime. 
  • Estimated Calculation: If legacy IT maintenance costs $40 per policy annually and modernization reduces this to $28, with 1 million active policies, the annual IT operational savings would be $12 million. Additionally, if system downtime drops from 120 to 60 hours per year and each hour of downtime costs $10,000 in lost productivity, that’s another $600,000 saved annually.
• Time-to-Market KPIs: Track acceleration in new product development and launch cycles. 
  • Example Calculation: Previously, launching a new product took 12 months. Modern platforms enable launch in just 4 months. This 66% reduction means insurers can capitalize on market opportunities faster. For example, at an average new product ROI of $2 million per quarter, the accelerated launch could generate an additional $4 million in new revenue over a year.
• Customer Experience Metrics: Monitor increased use of digital channels, improvements in Net Promoter Score (NPS), and customer retention rates. 
  • Example Calculation: If digital self-service adoption climbs from 35% to 60% post-modernization, and each digital transaction costs $4 less than a call center interaction, with 2 million transactions annually shifting to digital, this yields $8 million in savings. If NPS improves from +10 to +35 and customer retention rises from 85% to 88%, with an average customer lifetime value of $1,200, retaining 30,000 more customers could deliver $36 million in additional value.
• Operational Resilience: Assess improvements in risk control, compliance, and adaptability to regulatory shifts. 
  • Example Calculation: Automating compliance and risk reporting could reduce audit preparation time by 70% if audits take 1,000 hours annually at $100/hour, automation saves $70,000 per year. Rapid regulatory compliance, reducing adaptation timelines from 12 weeks to 4, can also avert penalties or missed market opportunities, indirectly protecting millions in revenue.

For customer satisfaction, insurers can improve the experience through faster claim processing and more tailored product offerings. For instance, leveraging AI to automate claim settlements can reduce turnaround times from days to hours and help automatically settle up to 70% of claims, freeing staff for more complex cases and improving customer retention.

In terms of operational efficiency, streamlined workflows and automation drive notable productivity gains and cost reductions. Implementing automated underwriting, for example, can decrease processing time by 60%, allowing staff to process twice as many applications and reducing manual error rates.

Operational resilience is strengthened through better risk control, compliance, and adaptability to regulatory changes. With modular systems and automation, new regulatory reports or product adjustments can be implemented in a matter of weeks, not months, helping insurers stay compliant and responsive to shifting market demands.
