Knowledge Management cost model.

Methodology

This calculator estimates 3-year total cost of ownership for knowledge management based on publicly reported pricing ranges, implementation benchmarks from analyst reports, and customer-reported deployment costs across our review base.

Three deployment tiers are modeled — Lean (lowest published pricing or SMB-tier), Standard (mid-market default per analyst benchmarks), and Enterprise (full-feature deployment with named CSM, regulated-industry compliance, and dedicated integration scope).

Per-seat KM license ranges from $180/yr (Tettra/Notion) to $900/yr (RightAnswers enterprise). Implementation scales with content migration volume.

What's included

• License: Annual subscription × seats × contract years.
• Implementation: One-time deployment services — typically professional services from the vendor or a partner.
• Training: One-time admin + end-user training programs.
• Integration: One-time custom integration build — CRM, ticketing, HRIS, ERP connectors above what's included natively.
• Maintenance: Annual ongoing maintenance services, typically 18% of annual license per the category benchmark.

What's not included

• Internal staff time spent on procurement, evaluation, and rollout.
• Change management, communication, and adoption program costs.
• Infrastructure costs (cloud, networking) outside the vendor's stack.
• Custom development that goes beyond standard integration scope.
• Opportunity cost of not deploying alternative solutions.

Estimate only. Actual TCO varies significantly by vendor, contract terms, deployment complexity, and internal staffing costs. Use this calculator as a starting point for vendor conversations, not as a replacement for vendor quotes and internal cost modeling.
