ROI of Reinsurance Automation: Build a Business Case

ROI of Reinsurance Automation: Building the Business Case for Replacing Manual Treaty Operations

Last reviewed: November 2026

Every reinsurance COO knows the treaty team lives in spreadsheets. Few can tell the CFO how many hours that costs, which is why most automation proposals stall at the first budget meeting.

Short answer: The ROI of reinsurance automation is the measured value of avoided hires and errors, minus all costs, over a fixed horizon. A credible case starts from a time-based baseline and survives a deliberate haircut.

Key Takeaways

• Measure before you promise. A four-week time sample beats any vendor benchmark, because it is your own data.
• Capacity is not cash. Released hours only become savings if roles go or growth is absorbed without hiring.
• Growth cases beat cost cases. Absorbing more treaties with the same team is usually the stronger argument.
• Stress-test the numbers. If the case fails under a modest haircut, it is not ready for approval.

What Does ROI of Reinsurance Automation Actually Measure?

ROI of reinsurance automation measures net financial benefit against total cost over a set period, usually three years. The formula is simple: benefits minus costs, divided by costs.

The hard part is the inputs. Benefits must come from your own baseline, and costs must include everything, not just the licence.

Why Do Most Automation Business Cases Fail?

Most automation business cases fail because the benefits are asserted rather than measured. A slide saying "50% faster" gives a CFO nothing to test.

Three other gaps appear again and again:

• Headcount savings with no plan. The case assumes roles disappear, but nobody has agreed which ones.
• Missing running costs. Licences, support, upgrades and internal admin time are left out.
• No owner for benefits. Nobody is accountable for proving the savings after go-live.

Where Does Manual Treaty Work Actually Cost Money?

Manual treaty work costs money wherever people retype, recalculate or reconcile data that already exists elsewhere. Map these areas before you estimate anything.

Rekeying is often the biggest single item. Our analysis of duplicate data entry between underwriting and accounting shows how the same treaty term gets typed several times.

How Do You Build a Baseline the CFO Will Trust?

You build a trusted baseline by measuring time, volume and errors for the current process, before any tool is chosen. Use five steps.

1. Map the processes. List each treaty, accounting and claims task, with the team that performs it.
2. Sample the time. Ask staff to log hours by task for four weeks, ideally including a quarter-end.
3. Count the volumes. Record treaties, amendments, bordereaux, accounts and claims handled in the period.
4. Log errors and rework. Note every recalculation, reissued account and reconciliation difference, with its value.
5. Price it. Multiply hours by fully loaded cost, and record errors at their real financial impact.

The output is a cost per treaty and per process. That number makes later comparisons honest.

What Does a Worked ROI Example Look Like?

A worked ROI example shows how the same inputs can produce a weak case or a strong one. All figures below are illustrative, not benchmarks.

What is the cost-only case?

Assume a treaty and technical accounting team of eight, at a fully loaded cost of 80,000 each. The time sample shows 35% of hours on rekeying, manual calculation and reconciliation.

That is 224,000 a year of manual effort. If automation removes half of it, the team releases 112,000 of capacity each year.

Add 30,000 a year of expected error avoidance, taken from your own error log. Annual benefit is 142,000.

The case is positive but thin. Payback arrives only near the end of year three.

What changes in the growth case?

Now assume the business plan adds a quarter more treaties within two years. Without automation, that would need two extra hires from year two.

Avoiding those hires adds 320,000 over years two and three. Net benefit rises to 356,000, and ROI to roughly 91%.

Does the case survive a haircut?

HM Treasury's Green Book guidance on optimism bias notes that appraisers tend to be over-optimistic. It recommends explicit adjustments to costs, benefits and duration.

Apply that discipline here. Cut benefits by 25% and raise one-off cost by 25%.

The cost-only case fails, while the growth case holds. That is the honest message to take to the board.

Which Benefits Should a CFO Count?

A CFO should count benefits that are measurable, owned and realistically achievable. Other benefits belong in the narrative, not the ROI figure.

Keeping soft benefits outside the number protects your credibility. It also stops the case being rejected on its weakest line.

How Should the Business Case Be Structured?

The business case should answer strategy, economics, delivery and risk, not just cost. UK government business case guidance uses a Five Case Model for the same reason.

For a reinsurer, four questions cover most of it:

• Why now? Growth plans, staff turnover, or control findings that manual work cannot meet.
• What does it return? The baseline, the worked ROI and the stress test.
• Can we deliver it? Data migration, testing, cutover dates and internal staff time.
• What could go wrong? Third-party, data and adoption risks, with an owner for each.

Where Does Automation Help?

Automation helps most where staff calculate, rekey or match data, not where they judge risk. People keep the decisions throughout.

Reinsurance treaty management holds treaty structure, participation, retention, limits and commission formulas in one record. It applies configured premium, commission and settlement calculation rules, with versioning and an audit trail.

Bordereaux calculation and reconciliation calculates premium and claim shares and identifies mismatches. Finance teams still determine the cause of each difference.

Reinsurance Email Intelligence turns submission emails into one structured view and flags missing information. For Group Life and Credit Life, the Reinsurance Claim Core Platform adds rule checks and maker-checker approval.

Reconciliation is often the best first target. Our guide to manual bordereaux reconciliation across cedents explains why it breaks at scale.

How Do You Prove ROI After Go-Live?

You prove ROI by repeating the baseline measurements after go-live and comparing like with like. Name a benefits owner before the project starts.

What Should CFOs and COOs Do Before Approving Automation?

CFOs and COOs should insist on a measured baseline and a stress-tested case before approving spend. None of these steps needs a vendor.

• Run a four-week time sample across treaty, accounting and claims teams.
• Build both a cost-only case and a growth case from the same inputs.
• Apply a deliberate haircut to benefits and an uplift to costs.
• Name one benefits owner and agree the post-go-live metrics now.

Key Terms

• ROI (return on investment): Net benefit divided by total cost over a defined period.
• Fully loaded cost: Salary plus benefits, overheads and other employment costs for one role.
• Released capacity: Staff hours freed by automation, which are not a cash saving on their own.
• Payback period: The time until cumulative benefits equal cumulative costs.
• Optimism bias: The tendency to overstate benefits and understate costs and timelines.
• Benefits owner: The person accountable for proving that promised benefits are delivered.
