What does ElecAS Pro add over the free plan?

Pro adds cloud save and sync across devices, unlimited saved calculations, removal of ElecAS branding from PDF reports, your own company logo and accent colour on reports, project workspaces with folders, and priority email support.

Do I need an account to use the calculators?

No. All calculators work without an account. An account is only needed if you want to save calculations to the cloud, sync between devices or apply custom branding to PDF reports.

Do the paid plans unlock better calculations?

No. The calculation engines, standards tables and results are identical on every plan. Pro and AI Pro add storage, branding and AI Mode (cloud sync, project workspaces, custom logo, a plain-English assistant), never accuracy or extra standards.

Yes. The branded PDF report is free on every calculator; downloading it requires only a free account. Pro adds a custom logo on the report, and AI Pro adds a larger AI Mode allowance.

Can I use the free plan commercially?

Yes. The free calculators are used daily by engineers, contractors and electricians on real projects across Australia and New Zealand. Responsibility for verifying design outputs remains with the certifying engineer, as with any design tool.

ElecAS Pricing: Pick a Plan That Grows With Your Practice

All ElecAS calculators are free to use with no sign-up required to calculate; PDF export is free with a free account. The Pro plan adds cloud save and sync, unlimited saved calculations, custom logo and branding on PDF reports, and project workspaces.

Overview

Every ElecAS calculator is free, and no sign-up is needed to get a result. A free account adds PDF export. Pro adds what turns a calculation into project documentation: cloud save and sync, unlimited saved calculations, your own logo and branding on the PDF reports, and project workspaces. AI Pro adds AI Mode on top of Pro. Paying annually is cheaper per month than paying monthly on both paid tiers.

Key facts

Every calculator and PDF export is free; a free account is only needed to download the report.
Pro adds cloud sync, unlimited saved calculations, project workspaces and custom logo branding.
The calculation engines are identical on every plan; paid tiers never change the results.

Who this page is for

Engineers, contractors and consultancies comparing free and paid electrical design tools for Australian standards work.

What this tool helps with

Free plan: every AS/NZS calculator with no sign-up to calculate, unlimited calculations, save to your device, and free PDF export with a free account.
Pro plan: cloud save and sync across devices, unlimited saved calculations, custom logo and accent colour on PDF reports, project workspaces and priority support.
AI Pro plan for designers who describe a job in plain English and get the calculation back.

What is free in ElecAS, and what Pro and AI Pro add

The free plan is the whole calculator suite

Every ElecAS calculator is free to use with no sign-up required to run a calculation: cable selection, voltage drop, voltage rise, maximum demand (Tables C1, C2 and C3), conduit and cable tray fill, earthing, derating, power factor correction, generator sizing, UPS battery sizing, LED inrush, arc flash and the rest of the suite, plus the EleCAD single line diagram builder. There is no calculation cap and no daily limit.

Exporting is free too: downloading the branded PDF report (or the DXF from EleCAD) requires only a free account. The free-tier PDF carries your name, company and accent colour with full standards citations.

What Pro adds

Pro is for practitioners who live in the tools: cloud save and sync across devices, unlimited saved calculations, project workspaces that group calculations by job, a custom logo on PDF reports and priority support. The calculators themselves are identical on every plan; Pro changes how your work is stored, branded and organised.

What AI Pro adds

AI Pro extends Pro with a much larger AI Mode allowance. AI Mode lets you describe a job in plain English (the run length, the load, the installation method), and get the calculation back, run by the same engines as the calculator pages and exported as the same PDF. Usage is metered in tokens, and every plan shows the remaining balance on the AI Mode page.

Which plan actually fits

If you need a number and a compliance check, the free plan is the whole thing. Every calculator, every AS/NZS check and every clause reference is there, and no account is needed to get a result. Add a free account and you can export the PDF as well. Most people sizing the occasional cable never need more than this.

Pro is for producing documentation rather than answers. The dividing line is whether the output leaves your screen: your own logo and branding on the report, project workspaces to keep a job together, cloud sync so a calculation survives the laptop, and unlimited saved calculations so last month's submission can be re-opened and amended rather than re-entered.

AI Pro is for volume and for description-first work: where the job is faster to say than to fill in, or where you are running many variations. It is Pro plus a much larger AI Mode allowance, and the calculations it returns come from the same engines either way.

Monthly or annual, and what happens if you stop paying

Both paid tiers cost less per month on annual billing than on monthly, and the pricing grid shows the effective monthly rate for each cycle rather than only the headline. The saving differs by tier, so the toggle quotes it as "up to" rather than applying one plan's discount to the other.

Cancelling drops you to Free rather than locking you out. Every calculator keeps working, local .elecas project files keep opening, and cloud-saved calculations stay stored and return the moment you are on a paid plan again -- though cloud workspaces are not accessible while you are on Free, and exported PDFs revert to ElecAS branding. There is no timed trial, because the Free plan is the trial: it never expires, and it includes a one-off AI Mode token allowance so AI Mode can be tested on a real job before deciding.
