163×: The SaaS Idiot Index in an Age of Abundance

Eric Jorgenson just published The Book of Elon, a compilation of Musk's most useful ideas in his own words. One concept stuck with me: the Idiot Index. It is the ratio of a finished product's cost to the cost of its raw materials. If the ratio is high, you are paying for process waste, not value. Musk expects every engineer to know this number for every part in their system.

I first applied the Idiot Index to SaaS on LinkedIn on March 26. Not to infrastructure costs. To the actual cost of building the features behind every pricing tier. The piece traveled. What it did not name is why the ratio collapsed. So this is the rewrite. With the cause named, the five industries kept, the four-phase sequence fixed, and the part I got wrong added.

The ratio that used to make sense

In 2018, a SaaS company charges $29 for Starter and $199 for Business. The $170 difference unlocks four features. Advanced reporting, custom workflows, API access, audit logs.

Those four features cost $700,000 to build. With 2,000 Business-tier customers, the amortized cost is $350 per customer. Add $3 a month in infrastructure. The Idiot Index on that $170 premium: about 4×.

Four times. SpaceX Falcon 9 operates at 2.2×. A restaurant meal is 5 to 10×. A ratio of 4× means the customer is paying for engineering that was genuinely expensive. Defensible.

The ratio now

In 2026, those same four features cost $25,000. One engineer. A few weeks. Same 2,000 customers. Amortized build cost: $12.50 per customer total.

The $170 per month premium is now a 163× markup.

| Reference good | Idiot Index | |---|---| | SpaceX Falcon 9 | 2.2× | | Nespresso pod | 10× | | Zara t-shirt | 12× | | Gucci handbag | 30–80× | | Branded pharmaceuticals | 30–600× | | SaaS Business tier, 2026 | 163× |

A SaaS Business tier in 2026 has a higher Idiot Index than luxury fashion. The pricing page has not moved. The cost underneath collapsed by 30×.

What happened

Vibe coding made the mechanical act of writing code nearly free. Build cost dropped 15–40× in eighteen months.

| Capability | 2018 cost | 2026 cost | |---|---|---| | Dashboards | $200–400K | $5–12K | | Workflow automation | $300–600K | $8–25K | | API access | $80–200K | $3–8K | | SSO / SAML | $80–200K | $5–15K | | Audit logs | $120–250K | $3–10K |

This collapse has a name. Tom Blomfield called it the Age of Abundance in his April 2025 essay. The argument is the same one, viewed from the macro side. When the cost of producing a class of work drops by an order of magnitude, the equilibrium that the pricing was anchored to disappears. The price does not drop with the cost. Not at first. The gap is the Idiot Index expanding.

So the two concepts pair. The Age of Abundance names the cause. The Idiot Index names the receipt. Read together, they describe a system where the foundation is gone but the pricing tiers are still standing.

Five industries, same pattern

Every industry where production cost collapsed saw the Idiot Index on its old pricing model go from honest to absurd.

Music. Recording: $500K → $1K. CD pricing: 3–5× became 150×. Spotify won because per-song pricing no longer reflected the cost of making a song. Value moved to curation.

Photography. Film: $0.50 per photo → free. Camera megapixel tiers died. Value moved to organization and memory.

Telecom. Calls: $0.10 per minute → free. Per-minute tiers died in three years. Carriers that clung to them became symbols of gouging.

Publishing. Print: $50K → $0. Substack charges for taste, not words.

Television. HBO's $15 add-on was justified by production cost. Netflix offered everything for $9.99. Per-channel gating collapsed.

Five industries, fifty years, same four-phase sequence.

1. The ratio is honest. Production is expensive. Price reflects cost.
2. The ratio becomes absurd. Production collapses. Price does not.
3. Someone names it. New product, everything at one price.
4. The value axis shifts. To what is still scarce.

SaaS is in Phase 2. Year one.

What I got wrong

When I published the original piece I assumed the math would travel. The math is in the article. Anyone reading it can run it on their own product. I thought that would be enough to make the Idiot Index visible from the buyer's side.

It was not. Buyers do not know what the same four features cost to build today. They have no current denominator. The Idiot Index is visible from the inside of a company that ships software. From the outside, it is invisible until a competitor prices closer to cost. Then it is suddenly visible everywhere, all at once.

That is the actual mechanism. Not gradual repricing. A delay, then a snap. The companies that win the next 24 months are the ones that snap their own pricing before someone else snaps it for them.

The other thing I underestimated is how fast Phase 2 compresses. I called it year one. Six months in, year one already feels half spent. The new entrants pricing at cost are not patient. They are not waiting for the incumbents to renew. They are pricing the renewal away from them.

What is still scarce

Features were never the value. They were the proxy, because they happened to be expensive. When they are free, the proxy breaks.

What remains scarce:

• Data accumulated over years. Connected, structured, attributed. Tied to a business that has been running for a while.
• Compliance certifications that take months of audit. SOC 2, GDPR, country-specific tax certification, banking partnerships.
• The taste to know what five features matter out of five hundred. The opinionated default that ships when the founder has watched ten thousand customers fail at the un-opinionated version.
• AI inference quality that depends on craft, not code. Prompt design, retrieval, evals, the loop between model output and the data it grounds on.
• Reliability at scale that cannot be vibe-coded. Uptime, throughput, edge cases handled. The reason a CFO sleeps.

None of these are code. They are what remains after code becomes free.

YC's 2026 Request for Startups names this exact bet from the other side of the table. The ask is a system that pulls knowledge out of every fragmented source, structures it, keeps it current, and turns it into an executable skills file for AI. They call it the company brain. Same insight, three vantage points. The Age of Abundance names why features got cheap. The Idiot Index names the receipt. The company brain names what gets expensive instead.

Where this goes

In twelve months: commoditized features free on new products.

In thirty-six months: feature-gated pricing survives only for features with real ongoing cost. Everything else becomes table stakes.

The surviving SaaS pricing models will look more like the Netflix correction than like 2018 SaaS. Bundled. Cost-anchored where cost still exists. Value-anchored where the value is anchored to something that did not get cheap.

At Well, we could gate reporting behind a Pro tier. The code is written. But the Idiot Index on that premium would be over 100×. I know what Musk would call that.

The cost of code hit the floor. Every SaaS pricing page built on the assumption that features are expensive is a document describing a world that no longer exists.
