Capital Cluster C — Operational Scaling
Developer Efficiency Audit
Four calculators that separate infrastructure cost from infrastructure theatre.
Every technical choice compounds. Cloud Exit answers whether self-hosted hardware beats managed services over a realistic horizon. Tech Debt Interest quantifies the ongoing tax that short-term hacks cost long-term. The Crossover finds the exact month a subscription becomes more expensive than a lifetime purchase. Value Floor defines the hourly rate below which DIY costs more than outsourcing. Together they audit where engineering time and infrastructure money actually go.
Start here
- Cloud Exit — Self-host break-even month vs managed services.
- Tech Debt Interest — Compounding cost of the hack you shipped last quarter.
- Crossover — Subscription vs lifetime — the exact month one beats the other.
- Value Floor — Below what hourly rate does DIY actively cost you money.

Curated guides
- Cloud ExitCumulative cloud cost vs (hardware ÷ depreciation) + electricity + maintenance + uptime risk.
- Tech Debt InterestInitial fix × (1 + growth)^months — velocity makes the exponent larger.
- Subscription vs Lifetime CrossoverDivide the lifetime price by the monthly fee — with an optional opportunity-cost correction.
- The Value FloorYour productive hourly rate is the baseline. Outsource when a pro can do it for less.

Frequently asked questions
› Why four tools instead of one build-vs-buy calculator? Troubleshooting
Each answers a different question. Cloud Exit is about infrastructure. Tech Debt Interest is about shipped code. Crossover is about software licensing. Value Floor is about personal time. Merging them loses the structural differences in each decision.
› Do these account for opportunity cost?
Yes — Cloud Exit and Value Floor both take a hurdle rate as input. Set it to your expected return on deployed capital and the math reflects that.
