The Cost of Building Software Is Collapsing
Modern engineers with agentic workflows are redefining what it costs to create and maintain software — and what products can eventually charge.
For two decades, software prices were anchored to how many people it took to build and sustain a product. That anchor is breaking. This article uses measured output from my live velocity dashboard to walk the arc: what it used to cost, what it costs now, how large the efficiency gap is, and why that points toward more affordable software — not bigger headcount budgets.
The thesis
When the cost to produce falls by orders of magnitude, the price of software does not have to stay where headcount-era economics put it. Incumbents may hold list prices for a while — margins absorb the gap first — but new entrants can undercut on economics alone. Over time, that is the road back to affordable products and services: clinical tools, vertical SaaS, internal platforms, and consumer apps priced for adoption, not for covering a 500-person delivery org.
output vs. a 100-engineer team
what that pace used to cost / yr
cheaper to build (full org, onshore)
Step 1 — output is rising
Recent full months measure 401K net lines across managed codebases — roughly 5× a 100-engineer hand-coded team (generous Capers Jones baseline: 750 net lines / developer / month). The chart below shows the trajectory, not month-to-month noise.
Step 2 — what it used to cost to build & maintain
At this measured pace, a traditional model implies about 535 coders — or a 986-person delivery org once you add PM, QA, platform, IT, HR, leadership, and facilities overhead. That is the old economics software pricing was built on.

Engineers only

Floor: coding payroll only, onshore, fully loaded.
Full delivery org
~$194M–$282M / yr onshore
What it actually took to ship at enterprise scale — the cost base behind legacy pricing.
Step 3 — what it costs now
A principal-level AI-native operator with product judgment — fully loaded salary, benefits, and tooling — runs ~$350K–$500K/yr in this model. Same measured throughput band. Radically different production economics.
Step 4 — the efficiency multiplier
Divide old production cost by new production cost. Same output, fraction of the spend — roughly ~209–400× on an engineers-only comparison, and ~388–806× against a full onshore delivery org. That is the lever that can eventually show up in what customers pay.
Step 5 — what this means for price
Production cost and list price decouple slowly — contracts, roadmaps, and brand moats lag behind engineering reality. But the direction is clear: when building is ~388–806× cheaper for equivalent output, someone will price like it. A $50K/yr vertical SaaS product with a $200M build org behind it faces a structurally different competitor than one built at modern production cost.
Affordable software is not a charity outcome — it is what happens when creation gets cheap again. Healthcare workflow tools, clinician-facing AI, internal ops platforms: categories priced for enterprise headcount can be re-built and re-priced on efficiency. Not overnight. But the math points there.
Modern engineers are not valued by their payroll line — they are valued by how far they move the production-cost curve, and therefore what products and services can sustainably charge.
What this analysis does not claim
- Lines ≠ business value. Net LOC is an auditable production proxy — not revenue or clinical impact.
- Prices do not fall automatically. Competition, regulation, and go-to-market still matter; this is about the floor moving.
- Not every team can run this way. Senior judgment, domain depth, and disciplined agentic workflows — not tools alone.
- Cloud and vendors are additive. We model people cost to build; infrastructure bills remain.
