Rethinking the Budget From the Ground Up at Your Insurer

For Australian general insurers, life companies and reinsurers feeling the squeeze of softer premium cycles, higher reinsurance costs and the operational lift of IFRS 17, zero-based budgeting has moved from corporate finance theory into a working tool. Rather than rolling forward last year's numbers and adjusting for inflation, the discipline starts each cycle by demanding that every activity justify its cost from scratch. That fresh lens can expose dormant subscriptions, duplicated vendor contracts, and staffing levels that drifted away from actual workload years ago.

A practical rollout is less about spreadsheets and more about redesigning how finance, actuarial, operations and IT work together. The approach rewards insurers that have invested in policy administration modernisation, clean cost-allocation models and disciplined procurement. It also raises questions that finance leaders across Sydney, Melbourne and Brisbane are debating today: where does the cycle start, who owns each decision package, and how do you keep the model credible when a hard reinsurance renewal or a severe weather season reshapes priorities.

What Zero-Based Budgeting Actually Demands of an Insurer

The textbook definition is simple: every line item must be justified as if the function were being built for the first time. In practice inside an insurer, that means breaking the cost base into decision units — a claims team in Adelaide, a specialty commercial underwriting desk in Parramatta, a contact-centre function supporting NSW strata policies, an actuarial model build squad, a managed security operations provider — and asking each to build a package that names the activities performed, the resources consumed, the outputs delivered, and the cost at each plausible funding level. Those packages then compete against strategic priorities rather than against last year's variance.

The contrast with traditional incremental budgeting is sharper in insurance than in many sectors because the underlying cost drivers are so varied. Premium handling blends fixed salaries with variable transaction fees. Claims spans internal adjusters, external loss-assessing firms, legal counsel and catastrophe response vendors. Investment operating costs, distribution commissions, and the technology stack that runs policy administration and reinsurance accounting each behave differently under stress. Zero-based budgeting forces those distinctions onto the table, which is exactly where finance partners add the most value during annual planning.

Building the Business Case Your Executive Will Sign

A zero-based programme rarely survives without a credible case anchored to outcomes the board and executive committee already track. Start with a realistic savings envelope — three to seven per cent of operating expense is a common first-year target before reinvestment. Pair that with non-financial benefits that resonate locally: improved IFRS 17 allocation accuracy, cleaner data feeding APRA's reporting returns, faster scenario analysis when reinsurance treaties come up for renewal, and stronger evidence of cost discipline for the audit committee in the wake of the Royal Commission.

Select a pilot that is bounded enough to deliver in a single planning cycle. A regional claims operation, a single product line such as domestic motor, or a contained corporate function like facilities and procurement typically works well. Make sure the pilot has a respected general manager willing to challenge entrenched assumptions, and ring-fence finance business partnering capacity to run the methodology properly. Document the methodology, the lessons learned and the reinvestment plans so the second wave moves faster. Australian insurers that began pilots in their contact centres or underwriting support functions have found the credibility earned there paved the way for company-wide rollout within two planning cycles.

Decomposing Spend Into Decision Packages

The heart of the methodology is the decision package. Each package needs a clear owner, a defined scope of activities, the resources required at multiple funding scenarios — for example 80 per cent, 100 per cent and 120 per cent of baseline — and the operational and customer outcomes expected at each level. Activity mapping is where insurers often underestimate the work. A motor claims package in Melbourne might bundle intake, triage, repair network management, total loss settlement, subrogation, complaints handling and reporting. Each activity needs its own cost driver — claim notifications, active claims, litigated claims, complaints — and a credible unit cost.

Cost allocation deserves particular attention because APRA and IFRS 17 reporting depend on accurate attribution between acquisition, maintenance, claims and investment functions. Where shared services such as IT, finance, HR and procurement support multiple business units, allocate them through transparent drivers rather than revenue-based keys that distort the picture. The discipline surfaces decisions that incremental budgeting tends to hide: a software licence no one actively uses, a consultancy retainer that survived three procurement cycles without a fresh tender, a contact-centre roster built for peak catastrophe response but rarely scaled back in quieter months.

Data, Systems and the Analytical Backbone

A zero-based approach cannot survive on spreadsheets alone. Insurers running annual planning on a modern enterprise planning platform — an integrated ERP, a dedicated budgeting tool, or a cloud-native planning suite — gain the ability to flex scenarios quickly and trace every number back to a driver. Mature Australian insurers link planning models to claims systems, policy administration platforms, HR data and vendor spend ledgers so finance partners and business owners share a single view. Where those integrations are weak, the cycle devolves into negotiation rather than analysis.

Decision quality rises when cost transparency extends into procurement and vendor management. Contract catalogues, rate cards and tiered usage assumptions let decision-makers compare like with like. This is particularly valuable for the technology vendors that populate the IASA Conference exhibit hall, from core platform providers to niche analytics specialists, because the planning conversation shifts from "what did we pay last year" to "what activity are we buying and at what unit cost." The methodology rewards organisations that invest in data governance ahead of the budget cycle, not during it.

People, Process and the Cultural Reset

Even a technically sound methodology stumbles if the organisation treats it as a finance project. Australian insurers that have succeeded tend to pair a clear executive sponsor — often the CFO or a deputy — with a planning lead who carries genuine authority across the business. The planning lead needs a small central team to maintain the methodology, train decision-package owners, run quality reviews and challenge weak submissions. Business owners, in turn, need protected time, training on the format, and a clear escalation path when their package is questioned.

Communication cadence matters more than most teams anticipate. A pre-cycle kickoff that frames the strategic context, mid-cycle check-ins that surface common problems, and a transparent review forum where decision packages are compared side by side turn the process from a compliance exercise into a learning loop. Recognition travels a long way: surfacing teams that identified genuine savings, reinvested them in service quality, and improved customer outcomes builds appetite for the next cycle. Where the process feels punitive or arbitrary, it will be gamed the next year and credibility will erode.

Governance, Controls and Local Regulatory Fit

Zero-based budgeting sits comfortably within APRA's prudential expectations around risk management, outsourcing and operational resilience, provided the programme is governed properly. Governance committees should define decision rights, sign off on methodology changes, monitor implementation risk and ensure that cost decisions do not compromise capital, liquidity or policyholder outcomes. Internal audit, the second line, and risk functions each need visibility into the programme so that findings surface early rather than after the fact.

The framework also intersects with broader governance topics insurers are wrestling with right now. Underwriting decisions that are increasingly automated raise questions about model accountability, fairness and customer outcomes — and budget choices around data, tooling and oversight directly shape those answers. Readers working through these questions will find practical guidance in Building a Framework for Ethical AI Use in Underwriting, which maps well onto the governance chapter of a zero-based programme. Tax treatment of emerging technology investments also carries real budget consequences, and the implications for distributed ledger pilots and crypto-asset exposures are explored in Understanding the Tax Treatment of Distributed Ledger Transactions in Insurance, worth reading before locking in any multi-year technology commitments.

Sustaining the Model Beyond Year One

The first cycle is the most expensive. Cycles two and three should run faster, with templated decision packages, refreshed activity dictionaries, and tighter links between planning outputs and monthly forecasting. Many Australian insurers find that the real payoff arrives in the third cycle, when business owners can flex packages in near-real time as conditions change — whether that is a reinsurance pricing shift, a regulatory update from APRA or ASIC, or an unexpected claims event in a particular region.

Continuous improvement also means challenging the methodology itself. Activity mappings that no longer reflect how work is done should be retired. Drivers that create unstable results should be redesigned. Pilot programmes that did not deliver should be reviewed openly rather than quietly shelved. Professional development resources such as the industry resource hub can help planning teams keep their craft current, particularly as new technologies and regulations reshape the cost base. With steady investment in the central planning capability, zero-based budgeting evolves from a periodic event into the way the organisation thinks about cost.

Plan to bring your zero-based budgeting questions to the IASA Conference, where insurance CFOs, controllers and operations leaders share the playbooks, governance models and tooling choices shaping the next generation of insurance finance.
