Customer Churn Analysis: A Worked Example With Data and Formulas
Work through customer churn analysis with three downloadable CSV files, churn-rate formulas, cohort checks, and a renewal list ranked by revenue at risk.


TL;DR: Most teams arrive at "Power BI vs Tableau vs QlikView" looking for answers from their data — not a dashboard project. This guide compares the three on real pricing and strengths, and covers where an AI-native analysis workspace such as Anomaly AI fits for teams that want analysis, dashboards, and recurring reporting from Excel, GA4, BigQuery, Snowflake, Google Sheets, or MySQL without assembling a BI stack first. Power BI, Tableau, and QlikView still fit dashboard-heavy enterprise teams; which one fits depends on your situation.
Disclosure: Anomaly AI is our product. It appears here where its capabilities fit the criteria below, and every claim about it is held to the same standard as the other tools.
Every data team I've worked with hits the same wall. Someone in the business needs a number. That number lives inside a spreadsheet, a warehouse, or a SaaS tool. By the time it surfaces in a dashboard built in one of the big three BI platforms, the question has already moved on. The dashboard is polished, governed, and a week late.
"Power BI vs Tableau vs QlikView" is a legitimate search — the three platforms that show up in most RFPs are Microsoft Power BI, Tableau (owned by Salesforce), and Qlik's product line (QlikView being the older product, now largely replaced for new customers by Qlik Cloud Analytics). All three are mature, widely deployed, and battle-tested.
But step back and look at what the team actually wants. Answers. Fast. Trustworthy. Data team doing investigation work, not tile-assembly work. The BI-tool comparison is the artifact of a 2015 decision tree — pick a dashboard platform, model the data, build the tiles, maintain forever. In 2026, there's a newer decision tree that starts one step earlier: do you actually need a dashboard project, or do you need a question-answering layer that sits on top of your data?
That's the frame this guide uses. We'll cover Power BI, Tableau, and QlikView honestly — their real pricing, strengths, and the cases where each still fits — and then where an AI-native analysis workspace fits for teams whose job is answering questions rather than shipping dashboards.
Each tool is compared on the criteria that decide a BI choice: data sources and connectors, output types (dashboards, reports, exports), Excel round-trip, how traceable each number is back to its logic, and pricing basis. Prices and plans were checked against each vendor's own pricing page in 2026 and are dated where they matter; the order tools appear in reflects fit to a described situation, not a ranking.
Microsoft Power BI is widely deployed, especially in organizations on Microsoft 365 and Azure. It plugs directly into Excel, connects to SharePoint and Teams, inherits Azure Active Directory identity, and sits on top of Microsoft Fabric with Copilot as the AI assistant. If your org runs on Microsoft, Power BI has the shortest integration path.
Real strengths: governance and enterprise admin are mature. Row-level security, workspace permissions, and deployment pipelines work the way an enterprise BI team expects. Excel integration is tight. Copilot adds natural-language querying on top of the semantic model and is improving quickly.
Real weaknesses: DAX is its own language, and expressing anything nontrivial in it is a skill most teams underestimate. Per-user pricing adds up fast at viewer scale. Fabric capacity billing is separate from per-user licenses, and the total cost of a serious Power BI deployment is usually several times the headline seat price.
Pricing: Power BI Pro is $14 per user per month, Premium Per User is $24 per user per month, and Fabric capacity is billed separately on top per the Microsoft Power BI pricing page. Power BI Desktop is free for individual authoring but not for sharing.
When Power BI is the right answer: you are already a Microsoft shop, you need governed self-service BI for a broad internal audience, and you want Excel to stay part of the workflow. The ecosystem gravity is real and it's usually the deciding factor.
Where Anomaly AI fits instead: when you don't want to pay Fabric capacity billing, don't want your team learning DAX just to answer questions, and care more about fast answers than polished dashboards. The free tier covers a lot of the work Power BI Pro seats are often bought for.
Tableau is a mature visualization platform owned by Salesforce, with Tableau Agent as the AI layer and Tableau Pulse for proactive insights. Tableau's visualization grammar is genuinely powerful, and the drag-and-drop exploration experience is polished in a way that matters for teams whose output is an executive-facing dashboard.
Real strengths: if visualization craft is the job — executive storytelling, published dashboards for thousands of users, customer-facing embedded analytics — Tableau earns its place. Tableau Prep handles upstream cleaning, and the connector library covers most enterprise sources.
Real weaknesses: per-user pricing compounds quickly at scale, and most companies end up on a mixed Creator/Explorer/Viewer seat model. Building a dashboard is still building a dashboard, even with Tableau Agent — you're automating the authoring, not eliminating the authoring step. For teams whose actual need is "answer this week's question," that's the wrong overhead profile.
Pricing: per the Tableau pricing page, Tableau Enterprise starts around $35 per user per month for the Creator role, with lower prices for Explorer and Viewer seats; Salesforce also offers a cloud-hosted Tableau+ tier. Exact pricing depends on seat mix, deployment (Cloud vs Server), and region.
When Tableau is the right answer: dashboards are the product, not the byproduct. You have a dedicated BI team, you need publication-quality interactive visualizations, and the business has a committed roadmap of governed dashboards to ship and maintain.
Where Anomaly AI fits instead: when your job is getting answers rather than shipping dashboards, you don't have a dedicated BI team, and you want the unit of work to be "ask a question and see the SQL" rather than "open a workbook and add a sheet."
QlikView is the older of Qlik's two analytics products. It was the platform that introduced the associative data model — a way of exploring data where selections in one field automatically propagate across every related field, surfacing both what matches and what doesn't. That model is still distinctive, and for certain exploration workflows it's a real advantage.
The important framing: Qlik's own roadmap in 2026 prioritizes Qlik Cloud Analytics (formerly Qlik Sense Cloud), not QlikView. QlikView is largely in maintenance mode for existing customers. New Qlik deployments in 2026 are overwhelmingly on Qlik Cloud Analytics. If you're shopping for a BI tool today and "QlikView" came up because it was on an old RFP template, the real comparison is Qlik Cloud Analytics vs the rest of the field.
Real strengths: the associative engine is genuinely different from the SQL-based model the rest of the field uses, and teams doing complex exploratory analysis in regulated industries (financial services, healthcare, government) sometimes find it indispensable. The in-memory data compression is efficient. The install base in regulated sectors is sticky.
Real weaknesses: the associative model is powerful but unfamiliar — there's a real training cost. The ecosystem is smaller than Power BI's or Tableau's. QlikView itself is aging out; Qlik Cloud Analytics is the active product, and migrating from one to the other is a project in its own right.
Pricing: Qlik Cloud Analytics (the modern successor, verified live against the Qlik Cloud Analytics plans and pricing page): Starter $300/month (10 users, 10 GB data, billed annually), Standard $825/month (25 GB data), Premium $2,750/month (50 GB data, predictive ML and GenAI add-ons), and Enterprise starting at 250 GB with custom pricing. Note that Qlik prices by data-for-analysis capacity plus user counts, not a flat per-seat model — the comparison to Power BI and Tableau isn't apples-to-apples.
When QlikView is the right answer: you're already running it, your regulated workflows depend on it, and the cost of migration outweighs the benefits. Otherwise, look at Qlik Cloud Analytics instead.
Where Anomaly AI fits instead: when you're starting fresh and don't want to inherit a stack you'll be migrating in two years, and you want the analysis layer to sit on top of data you already have in BigQuery, Snowflake, MySQL, or spreadsheets, without a platform-level data-capacity contract.
Anomaly AI is an AI data analysis workspace for teams whose data has outgrown spreadsheets and who want answers without assembling a BI stack. You connect your data once, ask questions in plain English, and get back answers with the generated SQL exposed underneath every result — no DAX, no LOD expressions, and no vendor-specific scripting language, with logic you can verify line by line.
The points that matter for the comparison in this article:
Where Anomaly AI fits: teams that want answers more than dashboards, whose data lives across multiple spreadsheets and a warehouse, who want to verify analyst work without a ticket queue, and operators who need to self-serve on numbers without a BI team. Where it does not fit: organizations whose deliverable is a governed, pixel-perfect executive dashboard — the same three KPIs rendered the same way for years, row-level security across thousands of users, and the BI tool as part of a regulatory audit trail. That is a legacy BI job, which the three sections above cover.
The cleanest way to pick a tool in 2026 is to start with the outcome, not the product category. Here's the decision tree that matches how the market has actually moved:
Many teams reading this in 2026 are in the first bucket. They came in thinking they needed a BI tool because that's what the search term implied, but the actual job is "get answers from our data faster than we currently can." For that job, an AI-native analysis workspace is often a lower-overhead path, and it doesn't preclude adding one of the legacy BI tools later if a governance or craft requirement genuinely shows up.
No. Governed enterprise dashboards are still a real job, and Power BI, Tableau, and Qlik Cloud Analytics are still the right tools for that job. What's changed is that an AI answer layer is now a realistic alternative: some teams who search "Power BI vs Tableau vs QlikView" want answers more than a full BI platform, and an AI-native tool is worth trying before committing to one.
For day-to-day self-service analysis it can. Where it can't replace Power BI is governed dashboards with row-level security across thousands of internal users — the enterprise BI role. For self-service analysis, cross-source joins, and agent-built outputs, Anomaly AI fits when you want the logic behind each number reviewable.
Anomaly AI's free tier is free ($0), and Pro is $25/month. Among the legacy BI tools, Power BI Pro at $14 per user per month is the lowest entry price; Tableau Creator is around $35 per user per month; Qlik Cloud Analytics starts at $300 per month for a ten-user Starter plan. Total cost scales very differently across these four — per-user for Power BI and Tableau, per-capacity for Qlik, and per-seat-with-a-free-tier for Anomaly AI.
Fabric is the unified data-platform layer Power BI sits on; Copilot is the AI assistant that generates DAX and answers natural-language questions against the semantic model. Both are real and improving. They're still dashboard-first — the unit of work remains the published report — and they're billed on top of the base Power BI license. Strong for Microsoft-centric teams; for everyone else the AI-native alternative skips the semantic-model step entirely.
The meaningful distinction is AI-native vs AI bolted onto dashboard tools. Power BI Copilot and Tableau Agent are AI layers on top of products designed before AI was the primary interface. Anomaly AI is designed around the AI-native model: plain-English question, agents inspect the data, follow-up analysis happens in the same workflow, and the result becomes a dashboard, report, slide, PDF, or scheduled update. The bolt-on approach works when the BI platform is already in place; the AI-native approach fits when starting from scratch without an existing BI platform.
Probably not. On the Anomaly AI free tier a solo analyst can connect spreadsheets and a database, ask for dashboards or reports in English, and review the logic behind the output, within the free plan's monthly credit allowance. Power BI Desktop is also free for solo authoring, but sharing anything requires a paid seat. Tableau and Qlik Cloud Analytics both start at team-oriented pricing tiers.
If you're reading this because someone asked you to pick a BI tool, it's worth trying an AI-native analysis workspace before committing to a dashboard project. It's free to start, takes about ten minutes to connect a data source, and answers the question most teams are asking: "can we get answers from our data without a six-month dashboard project?"
Try Anomaly AI free — Free $0 / Pro $25/month / Analyst $90/month / Team $45/seat/month (2-seat minimum) / Enterprise custom. Connect Excel, GA4, BigQuery, Snowflake, Google Sheets, or MySQL and ask for the dashboard, report, or analysis you need. If it doesn't cover your use case, the full Power BI / Tableau / Qlik comparison above still applies.
