What this calculator does
The Knowledge Base ROI calculator estimates the annual value of a searchable help centre: tickets and calls avoided because customers found the answer themselves. You provide contact volumes and handling costs; the model applies a deflection rate you control and shows the spread of outcomes.
The public sample report on this site is a real output of this calculator, built from the example dataset — see exactly what your stakeholders would receive before entering a single number.
How it works
Answer a short set of questions — volumes, time, and costs you already track. The calculator runs a pure, versioned formula and presents conservative, moderate, and optimistic scenarios, a receipt-style ledger tracing every figure back to an input, and a multi-year NPV/IRR view. Each report lists its assumptions so reviewers can challenge them line by line. See the methodology for how the models work, or view a complete sample report.
Benchmarks you can defend
- 81% of customers attempt self-service before contacting a live representative — a knowledge base is usually their first stop. Harvard Business Review, 2017 (Dixon et al.)
- Self-service contact costs roughly $0.10 versus $8.01 for live channels. Gartner, 2019 Customer Service and Support Leader poll
Every constant used in-product is cited — the full source list, with caveats, is on the methodology page.
Frequently asked questions
What deflection rate is defensible for a knowledge base?
Vendor blogs commonly claim 20–60% deflection, but no published study with methodology supports those ranges, so this product does not use them. Anchor on the customer-side reality instead — 14% of issues fully resolve in self-service (Gartner, 2024) — and let the scenario spread show what better-than-average execution would be worth.
Can I see a finished report before I start?
Yes. The sample report page shows a complete, real output of this exact calculator: headline verdict, three scenarios, the itemised receipt ledger, assumptions, and the multi-year NPV/IRR model.
Is the Knowledge Base ROI calculator free?
Your first calculator is free forever, with unlimited re-runs and one saved report — no card required. You enter your email to view and save results, and upgrading to Pro unlocks all 13 calculators, unlimited reports, exports, and share links.
Can I change the assumptions?
Yes — every assumption is editable before you calculate, and the report records exactly what you used. Industry constants are cited on the methodology page, and the receipt-style ledger traces each figure in the result back to an input.
