Aon is a global professional services firm that provides a broad range of risk, retirement, and health solutions. While Aon is best known for insurance brokerage and risk advisory, many organizations engage Aon for HR consulting, benefits administration, and workforce analytics platforms. Aon's pricing varies significantly depending on the service line, deployment model, and scope of engagement—from project-based consulting fees to subscription-based software licenses for platforms like Aon's Radford compensation data or Aon Hewitt benefits administration.

Aon's pricing structure depends heavily on the specific service or platform being purchased. Unlike pure SaaS vendors with transparent per-seat pricing, Aon typically quotes based on:
For software platforms like Radford compensation data or Aon's HR analytics tools, pricing generally follows a subscription model with annual fees ranging from mid-five figures for small deployments to seven figures for enterprise-wide implementations. Consulting engagements are typically priced per project or on a retainer basis, with fees varying widely based on scope and seniority of consultants involved.

Because Aon's pricing is highly customized, Vendr's pricing analysis tool helps buyers understand what similar organizations pay for comparable scopes and identify negotiation opportunities based on recent market transactions.
Aon's offerings span multiple service lines, each with distinct pricing models. Below are the most commonly purchased Aon solutions and their typical pricing structures.
Aon Radford provides compensation benchmarking data and analytics, widely used by HR and compensation teams to inform pay decisions.
Pricing Structure:
Radford pricing is subscription-based, typically quoted annually. Pricing depends on:
Observed Outcomes:
Based on Vendr transaction data, small to mid-sized companies (under 500 employees) purchasing a single survey subscription often see annual fees in the $15,000–$35,000 range, while larger enterprises with multiple survey access and advanced analytics may pay $75,000–$200,000+ annually. Multi-year commitments and bundling multiple surveys can unlock discounts.
Benchmarking context: Vendr's benchmarking data shows percentile-based pricing for Radford subscriptions by company size and survey scope, helping buyers assess whether a quote is competitive.
Aon Hewitt (now part of Aon) offers outsourced benefits administration, including enrollment platforms, call center support, and compliance management.
Pricing Structure:
Benefits administration is typically priced on a per-employee-per-month (PEPM) basis, with fees varying by:
Observed Outcomes:
PEPM fees generally range from $3–$12 per employee per month depending on service level and employee count. Larger organizations with simpler benefit structures may negotiate toward the lower end, while smaller companies or those requiring high-touch support often see higher rates.
Benchmarking context:
Vendr data shows that buyers who compare Aon Hewitt against alternatives like Mercer or WTW often achieve 10–20% better pricing through competitive leverage. See what similar companies pay.
Aon Decision Intelligence is an analytics and modeling platform used for workforce planning, risk assessment, and strategic decision-making.
Pricing Structure:
Decision Intelligence pricing is subscription-based, with fees determined by:
Observed Outcomes:
Annual subscription fees typically range from $50,000 to $250,000+ depending on deployment size and feature set. Implementation and onboarding services are often quoted separately and can add 20–40% to first-year costs.
Benchmarking context: Vendr's pricing tool provides percentile benchmarks for Decision Intelligence deployments, helping buyers understand typical pricing by user count and module selection.
Aon's consulting practice covers retirement, health, risk, and HR strategy. Pricing is typically project-based or retainer-based.
Pricing Structure:
Observed Outcomes:
Project fees vary widely—small engagements may start around $25,000–$75,000, while large, multi-phase projects (e.g., global benefits harmonization) can exceed $500,000. Retainer arrangements for ongoing advisory support typically range from $10,000–$50,000 per month depending on scope and consultant seniority.
Benchmarking context:
Vendr transaction data shows that buyers who clearly define scope and deliverables upfront, and who introduce competitive alternatives, often achieve 15–25% lower fees than initial proposals. Get your custom price.
Understanding the key cost drivers helps buyers budget accurately and identify negotiation opportunities.
Employee count and complexity: Larger organizations or those with complex benefit structures, multiple locations, or international operations typically face higher fees due to increased administrative burden and data requirements.
Service scope and modules: The breadth of services or platform features directly impacts pricing. Bundling multiple Aon solutions (e.g., Radford + benefits consulting) may unlock volume discounts, but also increases total spend.
Level of service: Technology-only solutions are less expensive than full-service offerings that include dedicated account management, call center support, or hands-on consulting.
Customization and integration: Custom reporting, API integrations with HRIS or payroll systems, and bespoke analytics add to both upfront implementation costs and ongoing fees.
Contract term: Multi-year commitments generally reduce annual pricing, but lock buyers into longer relationships. Aon often offers 10–20% discounts for three-year deals compared to annual contracts.
Timing and competitive pressure: Aon's pricing flexibility increases when buyers engage early, demonstrate clear alternatives, and negotiate during budget planning cycles rather than under time pressure.
Beyond the base subscription or service fee, buyers should budget for several additional cost categories:
Implementation and onboarding: For software platforms like Radford or Decision Intelligence, implementation fees can range from $10,000 to $100,000+ depending on complexity, data migration, and integration requirements. These are often quoted separately and may not be included in initial pricing discussions.
Professional services and training: Custom reporting, advanced analytics, and user training are typically billed separately. Training fees can range from $2,000–$10,000 per session, and ongoing professional services may be charged hourly or via retainer.
Data feeds and integrations: Connecting Aon platforms to existing HRIS, payroll, or benefits systems may require additional licensing or integration fees, particularly for non-standard connectors.
Annual maintenance and support: Some Aon solutions include a maintenance or support fee (often 15–20% of license cost annually) for software updates, technical support, and access to new features.
Scope creep in consulting engagements: Project-based consulting fees can expand if scope is not tightly defined. Change orders and additional phases can add 20–50% to original project budgets.
User overages: Subscription platforms may charge additional fees if user counts exceed contracted limits. Clarify overage pricing upfront to avoid surprises.
Benchmarking context: Vendr's pricing analysis helps buyers identify typical implementation and hidden cost ranges for Aon solutions, ensuring more accurate total cost of ownership (TCO) estimates.
Aon pricing varies widely by service line, company size, and scope, but Vendr transaction data reveals several patterns:
Small to mid-sized companies (under 500 employees) purchasing Radford compensation data typically pay $15,000–$40,000 annually for a single survey subscription. Those adding multiple surveys or premium analytics may reach $50,000–$80,000.
Mid-market organizations (500–2,500 employees) engaging Aon for benefits administration often see PEPM fees in the $4–$8 range, translating to $50,000–$200,000 annually depending on employee count and service level.
Enterprise buyers (2,500+ employees) deploying Aon Decision Intelligence or comprehensive consulting engagements frequently negotiate contracts in the $150,000–$500,000+ annual range, with multi-year deals and bundled services pushing total contract values into seven figures.
Discounting patterns: Vendr data shows that buyers who introduce competitive alternatives and commit to multi-year terms often achieve 15–30% off initial proposals, particularly for software subscriptions and retainer-based consulting.
Benchmarking context:
Because Aon pricing is highly customized, Vendr's free pricing tool provides percentile-based benchmarks tailored to your specific scope, helping you assess whether a quote is competitive before committing.
Aon's pricing is negotiable, particularly for larger contracts, multi-year commitments, and bundled services. Below are strategies that have proven effective based on Vendr transaction data.
Aon's pricing flexibility is greatest when buyers engage well before contract deadlines. Starting conversations 90–120 days before a desired start date allows time for competitive evaluation and multiple negotiation rounds. Clearly defining scope—employee count, service modules, integration requirements, and deliverables—prevents scope creep and anchors negotiations to a specific baseline.
Vendr data shows that buyers who provide detailed RFPs and involve procurement early often achieve 10–20% better pricing than those negotiating under time pressure.
Aon faces direct competition from Mercer, Willis Towers Watson (WTW), Gallagher, and niche providers like Payfactors (for compensation data) or Benefitfocus (for benefits administration). Demonstrating that you are evaluating alternatives—and sharing high-level competitive pricing—creates leverage.
Competitive benchmarks: Vendr's competitive analysis tool shows how Aon pricing compares to alternatives for similar requirements, helping buyers frame negotiations with market context.
Aon typically offers 10–20% annual discounts for three-year contracts compared to one-year terms. However, multi-year deals reduce flexibility and may lock you into pricing that becomes uncompetitive over time. Consider negotiating:
Aon often bundles implementation, training, and premium features into initial quotes. Request itemized pricing and evaluate whether all components are necessary. For example:
Vendr data shows that buyers who unbundle and negotiate line-item pricing often reduce first-year costs by 15–25%.
Aon's sales teams have quarterly and annual targets. Negotiating near quarter-end or fiscal year-end (many professional services firms align to calendar year) can unlock additional discounts. Similarly, if your renewal falls during your own budget planning cycle, use that as leverage to secure multi-year pricing certainty.
For managed services like benefits administration, negotiate clear service level agreements (SLAs) with financial penalties for non-performance. This not only protects you operationally but can also create leverage for pricing concessions if Aon is confident in their delivery.
These insights are based on anonymized Aon deals in Vendr's dataset across a wide range of company sizes and contract structures. Buyers can explore these insights directly using Vendr's free pricing and negotiation tools:

Decision Intelligence is typically purchased by large HR and finance teams seeking advanced workforce planning capabilities beyond standard HRIS reporting.
Yes. Aon Radford is available as a standalone subscription without requiring consulting services. However, many buyers choose to bundle Radford with Aon's compensation consulting practice for support with job matching, market analysis, and pay structure design. Bundling may unlock volume discounts but increases total spend.
Aon's software subscriptions and managed services are typically sold on annual or multi-year terms. Month-to-month contracts are rare and, when available, carry significantly higher per-month pricing (often 20–30% more than annual equivalents). Consulting engagements may be structured as shorter-term projects, but retainer-based advisory is typically quarterly or annual.
Based on analysis of anonymized Aon deals in Vendr's dataset, pricing varies significantly by service line, company size, and scope—but clear patterns emerge for buyers who prepare carefully. Recent data from Vendr shows that buyers who define requirements clearly, introduce competitive alternatives, and negotiate multi-year terms often secure meaningfully better pricing than those engaging under time pressure.
Key takeaways:
Regardless of platform choice, the most important step is clearly defining requirements, understanding total cost drivers, and benchmarking pricing against comparable deals before committing.
Vendr's pricing and negotiation tools analyze anonymized transaction data to surface percentile-based benchmarks, competitive comparisons, and observed negotiation patterns, helping buyers assess how a given Aon quote compares to recent market outcomes for similar scope.
