The short version

  • Each has a real cost: AutoCAD expensive subscription model with annual price increases of 5-8% and multi-year commitment premiums of 8-18%; Cadence Allegro cadence publishes no prices; resellers quote Allegro X from roughly $5,700 per seat per year on lease or about $18,000 perpetual with support, so the entry cost is several times a mainstream PCB tool and budget approval usually needs a business case.
  • They diverge on capability: AutoCAD covers 2D and 3D CAD, Cadence Allegro covers Constraint Manager.
  • Prices and features above were last checked on 31 August 2026.

Cadence Allegro

  • Routing a DDR5 or high-speed SerDes board where length matching and impedance rules must be enforced during layout, not checked afterwardsnot AutoCAD
  • A rigid-flex design with multiple stackups that a general-purpose PCB tool cannot represent correctlynot AutoCAD
  • A team of PCB designers working concurrently on partitions of one large backplanenot AutoCAD
  • An organisation that already runs Sigrity or Clarity analysis and wants the layout constraints and the simulation to share one rule setnot AutoCAD

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

AutoCAD

  • Expensive subscription model with annual price increases of 5-8% and multi-year commitment premiums of 8-18%
  • Desktop-centric design, limited cloud-native collaboration features
  • No perpetual license option, subscription required for continued use

Cadence Allegro

  • Cadence publishes no prices; resellers quote Allegro X from roughly $5,700 per seat per year on lease or about $18,000 perpetual with support, so the entry cost is several times a mainstream PCB tool and budget approval usually needs a business case.
  • The learning curve is steep and the interface carries decades of accumulated convention, so a designer coming from another tool needs weeks to become productive and formal training is effectively mandatory.
  • Capability is split across product tiers and add-ons, so the feature you assumed was in Allegro may be an extra SKU, and the quoted configuration deserves a line-by-line check against your actual requirements.
  • Perpetual licences still carry annual maintenance to stay on current releases, and lapsing maintenance means paying to rejoin later, so the perpetual option is only cheaper over a long horizon.
  • Library and part data management is a project in its own right; teams that treat it as an afterthought end up with inconsistent footprints that surface as manufacturing defects rather than design errors.

Answered from the vendors’ own pages

AutoCAD: What is AutoCAD's subscription pricing?

AutoCAD 2027 costs $2,095 annually for a single Named User subscription, $235 monthly, or $1,865 yearly. AutoCAD LT costs $500 annually. Prices have been increasing 5-8% annually.

Cadence Allegro: Can I still buy a perpetual Allegro licence?

Yes. Cadence channel partners quote both annual lease and perpetual licences for Allegro X, with perpetual starting around $18,000 including support. OrCAD X is more commonly sold as lease only.

AutoCAD: Is AutoCAD available for free?

AutoCAD is only available through subscription. However, eligible students can get AutoCAD free for one year with a .edu email address through the Autodesk Education License program.

Cadence Allegro: How does Allegro differ from OrCAD?

OrCAD X is schematic capture and mainstream PCB layout; Allegro X is the high-speed implementation environment with the full constraint manager. They share a database, so moving up does not mean redrawing.

Cadence Allegro: Is there a free or student version?

Cadence offers time-limited evaluation and academic programmes, but there is no free commercial tier.

Cadence Allegro: Do I need Sigrity as well?

Only if you need signal or power integrity simulation. Allegro enforces constraints but does not simulate; Sigrity is a separate purchase.
