How much does a Tableau to Power BI migration cost?

It depends on dashboard count and complexity, and only conversion labor is directly computable. At the ROI calculator defaults of 100 dashboards, 80 hours each and $85 an hour, that line is $680,000 rebuilt by hand. Licensing, parallel running, validation, training and data-platform rework sit on top of it. The manual against tool-assisted comparison is worked through on the migration ROI calculator page.

What is usually missing from a migration budget?

Three items: the parallel period when both platforms are licensed at once, the hours dashboard owners spend accepting their own content, and rework on the data platform when Tableau extracts turn out to have carried preparation logic. None of them scale with dashboard count, which is why per-dashboard estimates miss them.

What do Power BI and Tableau licenses list for?

As of August 2026, Microsoft lists Power BI Pro at $14.00 per user per month paid yearly and Premium Per User at $24.00, with a free account included in Fabric. Tableau lists its Standard edition starting at $15 per user per month billed annually and Enterprise at $35, with per-role licensing quoted separately.

Does a conversion tool remove the review cost?

No, and a budget should not assume it. The model used here keeps roughly a tenth of the manual effort as review, which is $68,000 on the default estate. Validation of the numbers by the people who own them is unchanged either way, since only they can confirm that a converted figure still means what it meant.

Tableau Migration Cost Estimation: The Budget Lines

A Tableau to Power BI migration budget breaks into six lines: conversion labor, licensing delta, parallel running, validation and QA, training and enablement, and data-platform rework. Conversion labor is where estimates start. The lines that overrun are usually the parallel run and the modeling work underneath the reports.

What follows prices the cost side only. Whether the total is worth spending is answered on the ROI page; which approach comes out cheaper is settled on automated versus manual economics.

What goes into a migration budget

Six lines, six drivers. A blended cost per dashboard hides that, which is why such budgets come out roughly right about conversion and wrong about everything else.

Budget line	What sits in it	What sets its size
Conversion labor	Converting or rebuilding each dashboard, reviewing calculations, rebuilding features with no counterpart	Dashboard count multiplied by effort per dashboard, which is a function of complexity
Licensing delta	Power BI licenses for authors and consumers, less what Tableau stops costing after decommission	Audience size by role, and the date the Tableau contract actually ends
Parallel running	Both platforms licensed, supported and refreshed while content is validated in production	Length of the parallel window, counted in months
Validation and QA	Reconciliation, interaction and security testing, plus the hours owners spend accepting their own content	Measures under the validation policy, and owner availability
Training and enablement	Separate sessions for consumers and authors, documentation, support through the first weeks	Number of people, not number of dashboards
Data-platform rework	Sources unreachable from the target tenant, gateways, refresh schedules, semantic modeling	Number of distinct sources and how much preparation logic Tableau extracts were hiding

How to price conversion labor

Manual conversion is priced as dashboards × hours per dashboard × blended hourly rate. On this site's ROI defaults, 100 dashboards at 80 hours and $85 an hour, that line reads $680,000. Tool-assisted conversion replaces most of that labor with a fee: at a flat $200 per source dashboard and review effort of roughly a tenth of a manual rebuild, the same estate is $20,000 of fees plus $68,000 of review, or $88,000. The one-tenth review share is Antares' product claim for its own conversions rather than an industry figure, and the ROI page carries the full worked comparison and its sensitivity. LLM usage sits outside that $88,000: typically under $20 per dashboard billed to your own provider, roughly $2,000 across a 100-dashboard estate.

Both are estimates, and hours per dashboard moves the total more than the rate does. That input spans 4 to 160 hours, because a page of standard charts on a clean source and one carrying nested level-of-detail logic across blended sources are not the same unit of work. Score the estate with complexity analysis first, then multiply band by band.

Power BI vs Tableau licensing costs: build the delta, not the total

The licensing line is the gap between two subscriptions with different shapes, and it becomes a saving only when the Tableau contract ends. Prices below come from the vendors' public pricing pages as of August 2026, before discounts.

Plan	List price, August 2026	Note
Power BI free account	Free	Included with a Microsoft Fabric free account; sharing reports requires Pro or Premium
Power BI Pro	$14.00 per user per month, paid yearly	The default author and consumer license outside capacity-based plans
Power BI Premium Per User	$24.00 per user per month, paid yearly	Microsoft's pricing page footnote lists a $14.00 per user step-up add-on for Pro, Microsoft 365 E5 and Office 365 E5 holders, as of August 2026
Power BI Embedded	Variable, contact sales	Listed without a figure on the Microsoft pricing page
Microsoft Fabric capacity	Priced by capacity, region and commitment	No single list figure applies; size it against your own region and reservation
Tableau Standard edition	Starting at $15 per user per month, billed annually	Cloud and Server both start here; every deployment needs at least one Creator
Tableau Enterprise edition	Starting at $35 per user per month, billed annually	Adds Advanced Management and Data Management
Tableau Cloud+ and Tableau+ bundle	Pricing on request	Listed as contact sales rather than as a rate

Power BI list prices are per user per month, so the annual delta is one multiplication: 100 authors on Pro is 100 by $14 by 12, or $16,800 a year, against what the equivalent seats cost today. Per-role Creator, Explorer and Viewer figures are not published there, so take those from your own contract. Which features need which license is set out in features by license type, with capacity options under Premium capacity.

Which costs migrations usually miss

Parallel running is the line most often left out of a first estimate. Both platforms stay live, and both meters run, while validation and user transition proceed. Shorten the window with waves and a change freeze rather than skipping it and finding the gaps in production.

Owner time rarely appears in a BI budget at all, because it sits on other departments' payroll. Those hours are still consumed, and owner calendars, not developer calendars, are what acceptance waits on. A plan assuming same-day sign-off from finance during a close has mispriced both schedule and budget.

Data-platform rework is the largest of the three when it lands. Tableau extracts can carry a lot of preparation logic, and reproducing it as a governed model with a gateway and scheduled refresh is engineering rather than conversion work. Size it from the count of distinct sources; Microsoft's proof of concept stage exists largely to expose it before a budget is signed.

What Antares changes in the budget

Two of these six lines move when a BI migration tool is involved. The inventory and complexity scores the conversion line depends on come from an Analyzer that is free, deterministic and metadata-only, so they cost nothing to produce, and the retirement candidates it surfaces leave the count altogether. Scope reduction is the only budget lever with no offsetting cost.

The fee itself is a multiplication rather than a negotiation: $200 per source Tableau dashboard, flat, with nothing charged per user and no expiry. Your own provider invoices the LLM work, under $20 per dashboard in most cases, and private endpoints are supported. Because the engine runs deterministic-first with guardrailed, validated AI steps toward like-to-like output, keep review time in the budget and redesign in a project of its own. Run the free Analyzer to replace the assumptions above with counts.
