Mike Holt price comparison (review 3)

Mike Holt is the gold standard for NEC training. His books, videos, and seminars have built careers. I own his stuff. This isn't a takedown. It's an honest look at what you pay for, what you get, and where a phone app like Ask BONBON fits next to it.

What Mike Holt Actually Sells

Mike Holt Enterprises sells training materials and reference books. The catalog is deep: Understanding the NEC Volume 1 and Volume 2, Changes to the NEC, exam prep packages, video libraries, and the NEC Code Book itself with tabs and highlights. Prices swing based on edition, format, and bundle.

Rough ballpark as of the 2023 cycle, straight from the site:

• Understanding the NEC Volume 1 (Articles 90 through 480), textbook only: around $85 to $95
• Understanding the NEC Volume 2 (Articles 500 through 820), textbook only: around $85 to $95
• Changes to the NEC, illustrated: around $70 to $85
• Full exam prep library with videos: $400 to $900 depending on package
• Tabbed and highlighted NEC Code Book: around $110 to $130

Add shipping, add a new edition every three years when the NEC updates, and a serious setup runs $500 to $1,500 over a code cycle. That is before any live seminar or continuing ed credit.

What You Get for That Money

You get depth. Mike's team explains the why behind articles like 250 grounding and bonding, 310 conductor ampacity, and 430 motor circuits. The illustrations are clean. The exam prep is proven. If you are sitting for a journeyman or master's test, his material works.

You also get a paper library. Paper is fine at the kitchen table. Paper is slower in a crawlspace at 2 PM when the GC is watching and you need to confirm 210.8(A)(6) for a kitchen island receptacle without a wall behind it.

Tip from the truck: keep the tabbed code book in the van for long reads and inspections. Keep a phone reference for the ladder.

Where a Phone App Fits Differently

Ask BONBON is not trying to replace Understanding the NEC. It is a different tool for a different moment. You pull out your phone, type or ask a question like "GFCI required for dishwasher" and get the article, the exception, and a plain-English answer you can read one-handed.

Subscription pricing for Ask BONBON is flat and monthly. No three-year refresh cycle. No shipping. No waiting for a new edition to arrive. When the 2026 NEC lands, the app updates. You do not rebuy a shelf of books.

Compare the moments these tools are built for:

1. Studying for the master's exam at home: Mike Holt, every time.
2. Teaching an apprentice the theory behind 250.122 equipment grounding conductor sizing: Mike Holt.
3. Standing on a scissor lift trying to remember the working clearance in 110.26(A)(1): phone app.
4. Inspector asks why you ran EMT instead of MC in a specific assembly: phone app for the quick cite, book for the long defense.

Honest Weaknesses on Both Sides

Mike Holt's material is heavy. Literally and in time commitment. Reading Volume 1 cover to cover is a winter project, not a lunch break. The video content is excellent but sit-down work. None of it is searchable from a gloved hand on a roof.

Ask BONBON has limits too. It does not walk you through a full load calculation example the way a textbook chapter does. It is a reference and a fast answer, not a curriculum. For deep theory and exam prep, a textbook still wins. A good electrician uses both.

If you are prepping for a licensing exam, buy the Mike Holt package. No app replaces that. Once you are licensed and working, your daily questions look different.

Cost Over a Code Cycle

Here is the math most guys do not run. A full Mike Holt library plus a fresh tabbed code book at each cycle is real money. Spread across three years it is maybe $15 to $40 a month depending on how deep you go.

A phone app subscription sits in the same range or lower, and covers a different job. The smart move for most working electricians is not picking one. It is stacking them: one textbook for deep study, one code book for inspections and long reads, one phone app for the ladder, the attic, and the parking lot conversation with the inspector.

Bottom Line

Mike Holt earns the price if you use it. The training is legit and has put more electricians through exams than anything else on the market. If you are a student, an apprentice, or sitting for a test, start there.

If you are a licensed electrician who already knows the theory and needs fast, accurate answers during the workday, a phone reference like Ask BONBON is the cheaper and faster half of the toolkit. Different tools, different moments. Use what fits the moment you are in.
