Electrical Calculations is a professional calculation suite for installers, designers, and electricians. It covers wire sizing, voltage drop, power, impedance, motor calculations, and more, with PDF reports for documentation. With 5,000,000+ total downloads and 18K in the last 30 days, it shows broad adoption, a 4.53 rating from 46,880 reviews, and top Productivity rankings in Italy (#99), Czechia (#154), and Spain (#173).

Pros & Cons

Broad coverage of electrical calculations (wire sizing, voltage drop, impedance, power, etc.)
Standards support for IEC, CEI, NEC, and CEC
PDF and printable reports for professional documentation
Extensive reference materials and wiring/pinout guidance

Competitors emphasize broader calculator and conversion capabilities (e.g., general calculators, transformer sizing, grounding, ampacity tables) which this app does not explicitly highlight in its feature terms
Potential for broader coverage of national code references and conversions that some competitors market heavily
Some users may seek more offline or standalone calculator features beyond standard calculations

Comments on Electrical Calculations for Android

★★★★★ Wayne Carter · Jun 21, 2025

Very complicated for an amature doing basic car and boat wiring but just focusing on wire size NEC calculator is such a useful tool to have.

★★★★★ Dave Tuck · Mar 29, 2025

The most useful app for electrical wiring! I'm wiring a battery system for 4wd batteries, lights, inverter, air and water pumps, solar panels, DC-DC charger and mppt charger. Look no further for an app that does wire size, voltage drop, resistance etc. etc. etc. Gold!

★★★★☆ Nadeem Qurashi · Aug 5, 2025

Please include all the calculations for three-phase power and distribution transformers as well as for motors, thanks.

★☆☆☆☆ Martin Axelsen · Oct 13, 2025

Most formulas are locked away behind a paywall. Instant uninstallation Reply: I'd rather have all formulas along with commercials

★★☆☆☆ Electrifying Services LLC · May 23, 2025

Looks like there's a lot of things in the app, but it did not do what I needed. Defaults to metric and even after changing it to imperial in the setting the drop-downs were still in metric. Not sure who this is for.

★☆☆☆☆ MOMIN UMAIR · Mar 4, 2025

Very Poor not give proper calculation Don't install this aap

★☆☆☆☆ Devang · Nov 1, 2025

Ads pop up right on clicking Calculate. I understand that a developer needs to cover costs, but this is ridiculous. Just a couple of years ago the app was $14.99 lifetime compared to $42.99 now. How much greed do you guys have? Update after Response: So you're telling me that $6/yr is cheaper than $14.99 lifetime from couple years ago cheaper? If I were to use an app for 20 years then 20x6 $120 (if you don't jack up prices) is cheaper than $15 lifetime? Greedy much.
