Why Engineering Software Pricing Keeps Developing-World Engineers on Spreadsheets

The global electrical engineering software market prices its products for wealthy-country salaries. This is not a conspiracy — it is the natural outcome of companies headquartered in the US, Australia, and UK building pricing models around their local customers. But the consequences for engineers outside these markets are severe.

And $700/year is the base licence. Full ETAP with arc flash, protection coordination, and cable sizing modules runs $5,000–$100,000+/year. ELEK Cable Pro is A$390+/year. jCalc is A$265/year. Even these “affordable” options represent 4–8% of annual salary for an engineer in Lagos or Jakarta.

The result is predictable and measurable: engineers in these countries use Excel. They build their own spreadsheets, copy formulas from colleagues, download templates from forums. Some of these spreadsheets are excellent. Many contain errors that nobody catches because there is no automated validation layer.

A 2024 survey of 340 electrical engineers across Southeast Asia (published by the ASEAN Federation of Engineering Organisations) found that 73% use Excel or Google Sheets as their primary cable sizing tool. Of those, 61% reported using a spreadsheet they did not create themselves. Only 12% had ever verified their spreadsheet against published standard worked examples.

This is not a failure of competence. These engineers know the standards. They can derive derating factors from first principles. The problem is economic: the cost of professional software exceeds what their employers can justify, and the cost of building a validated spreadsheet from scratch exceeds what any individual can invest in time.

The consequences are asymmetric. An undersized cable in a commercial building in Sydney will be caught by an inspector with access to the same professional tools. An undersized cable in a factory in Surabaya may not be caught because the inspector is using the same unvalidated spreadsheet. The physics of overheated conductors does not adjust for purchasing power.

ECalPro implements 5-tier regional purchasing power parity pricing via ParityDeals, applied through Paddle (Merchant of Record):

The floor is $5/month equivalent — below which payment processing costs make the transaction uneconomical. At $5/month, the annual cost for an engineer in Nigeria is $60/year, or 1.25% of salary — comparable to the 0.6% burden a US engineer faces at the full $29/month price.

This is not generosity. It is the minimum standard for ethical pricing of safety-critical professional tools. An engineer in Lagos designing electrical systems for a hospital has exactly the same professional obligation as an engineer in London designing for a hospital. They deserve access to the same quality of calculation tools.

The standard objection from enterprise software vendors is revenue leakage: engineers in wealthy countries will use VPNs to obtain developing-world pricing. This is a real concern, and it is solvable. Paddle’s Merchant of Record model validates billing address against payment method country. ParityDeals uses IP geolocation with manual override review. The combination catches over 95% of geographic arbitrage attempts.

The deeper reason is structural. Enterprise engineering software is sold through channel partners and multi-year site licences. A global mining company pays the same price for an ETAP licence in Perth and Jakarta because the procurement is centralized. PPP pricing requires direct-to-engineer sales — individual subscriptions purchased by individuals with personal payment methods. This is a distribution model that enterprise vendors do not have and do not want to build.

ECalPro is built for individual engineers from the ground up. No channel partners. No site licences. No sales team. This is not a limitation — it is the architecture that makes PPP pricing possible.

Electrical safety standards exist because people die when cables overheat, when arc flash incidents are not mitigated, when fault currents exceed equipment ratings. These failures do not discriminate by geography. A 35 kA fault on a 415 V bus produces the same incident energy in Dhaka as it does in Denver.

If we accept that validated calculation software reduces the risk of these failures — and the evidence from ECalPro’s own error analysis suggests it does — then pricing that software beyond the reach of 80% of the world’s engineers is a safety problem, not just an economic one.

PPP pricing for engineering software is not a marketing strategy. It is not a growth hack. It is not a loss leader for enterprise upsells. It is the recognition that the engineer in Mumbai designing a 500-unit residential tower has the same need for accurate cable sizing as the engineer in Melbourne, and should have access to the same tools at a price proportional to their economic reality.

ECalPro is the first multi-standard electrical engineering calculation platform to implement PPP pricing. We expect competitors will follow. The engineering profession will be better for it.
