The short answer: AutoCAD LT costs roughly a quarter of full AutoCAD — about US$540 a year against US$2,095 — and for a large number of people it is genuinely enough. The difference is not a crippled version of the same program. It is a deliberate split, and there are exactly three things that decide which side you belong on.
The price gap, and what it buys
| AutoCAD LT | AutoCAD | |
|---|---|---|
| Annual plan | US$45/month billed annually (~US$540/yr) | US$175/month billed annually (US$2,095/yr) |
| Monthly plan | US$70/month | US$260/month |
| 2D drafting and documentation | Yes | Yes |
| 3D modelling and rendering | No | Yes |
| Specialised toolsets | No | Architecture, Mechanical, Electrical, MEP, Map 3D, Plant 3D, Raster Design |
| AutoLISP / VBA / developer APIs | No | Yes |
| DWG format | Identical | Identical |

The three questions that settle it
1. Have you ever opened a 3D view? Not “would you like to” — have you actually needed to model in 3D for paid work? If your output is plans, sections, details and schedules printed to PDF, LT does that identically. The DWG file format is the same, so nobody receiving your drawings can tell which one you used.
2. Does your office run LISP routines? This is the one that catches people out. AutoLISP, VBA and the developer APIs are absent from LT. If your firm has accumulated custom routines over the years — block libraries, sheet-set automation, title-block fillers — none of them will run. Ask before you switch; the migration cost usually dwarfs the licence saving.
3. Do you use any specialised toolset? The toolsets are included with full AutoCAD and absent from LT — and that inclusion is most of what the price gap buys. If you draw walls and doors as real objects rather than lines, or generate wire numbering, or work with P&IDs, you are on full AutoCAD territory whether you realised it or not.
What LT does NOT lose
It is worth being clear about this, because a lot of comparison articles overstate the gap:
- The file format is identical. LT reads and writes the same DWG. There is no “LT version” of a drawing.
- Annotation, layouts, sheet sets, plotting — all present and identical.
- External references, dynamic blocks, tables, fields — all there.
- The web and mobile apps are included with both.
- Collaboration and cloud storage work the same way.
Hardware: LT is the lighter one
If you are buying a machine, the requirement that actually differs is memory and graphics, because full AutoCAD carries the 3D engine. Autodesk lists AutoCAD 2026 as 8 GB RAM basic and 32 GB recommended, with a 2 GB DirectX 11 GPU basic and an 8 GB DirectX 12 card recommended, and 10 GB of disk. LT runs comfortably below the recommended tier because you are never rendering. See our full system requirements comparison for the numbers across the whole Autodesk line.
The honest recommendation
- 2D drafting only, no custom routines, no toolsets: AutoCAD LT. You will not notice the difference, and you keep about US$1,555 a year.
- Any 3D, any toolset, any LISP: full AutoCAD. Do not try to work around it — the workarounds cost more in time than the licence.
- Genuinely unsure: open your three most recent drawings. If every object is a line, arc or polyline and no custom command appears in the command history, you are an LT user.
- Occasional use either way: look at Flex tokens first — see how much AutoCAD costs for the break-even maths.

Whichever you pick, the install and licensing faults are identical across both: error 1603, licensing errors, fatal errors.
