It benchmarks model speed, electricity consumption, and token usage to inform infrastructure decisions. Adopt it if your team evaluates whether to self-host models (e.g., for coding assistants, document summarization, or translation workflows) or if you're deciding between local inference and API subscriptions at scale. Best suited for technical founders, operations leads, and infrastructure-focused teams making capital allocation decisions.

Reality Check

Trade-offs & Gotchas

Sunkcost is a calculator, not a deployment tool, it informs the decision but doesn't execute it. The break-even analysis assumes stable token usage and electricity costs; real-world variables (model updates, API price drops, hardware depreciation) shift the math. Most agencies see payback periods measured in years, not months, making local hardware viable only for high-volume, consistent workloads.

Core concepts

The mental model you need to price and scope the work.

  1. Evidence Depth LadderConcept

    The Evidence Depth Ladder ranks research tools by how close their data sits to actual user behavior. At the bottom are self-reported instruments like conversational forms and surveys, which capture what people say but not what they do. Mid-tier tools add observational signals, such as session recordings or clickstream analytics, revealing real interactions. At the top are hybrid systems that combine both, often with AI-driven analysis to surface patterns. Agencies that climb this ladder replace guesswork with defensible recommendations, differentiating their strategy work. For example, a study of 107 million AI answers shows that citation gaps in AI-generated responses can be closed by grounding recommendations in behavioral evidence, not just survey responses. Pairing a tool like Typeform for structured feedback with behavioral analytics from Hotjar moves an agency up the ladder, making its client reports harder to dispute.

  2. Behavioral Signal GapConcept

    Research tools excel at capturing what people say, but they often miss what people actually do. The Behavioral Signal Gap framework urges agencies to treat survey and form responses as hypotheses, not conclusions, and to pair them with observational analytics that reveal real behavior. For example, a client's customer satisfaction scores might look strong, yet session recordings and heatmaps could show users struggling to complete checkout. By triangulating self-reported data with behavioral signals, agencies produce defensible recommendations that withstand client scrutiny. This framework is especially relevant as AI-powered forms and surveys become more sophisticated, generating larger volumes of data that can create false confidence. The risk of over-reliance on shallow, self-reported data is real; closing the gap between what users say and what they do is the difference between guesswork and evidence-driven strategy.

  3. Reach vs Rigor TradeoffConcept

    Research Tools span a spectrum from broad, shallow data capture to deep, controlled rigor. Typeform excels at conversational reach, gathering self-reported answers at scale, while Qualtrics-style platforms prioritize methodological control. The strategic insight for agencies is that neither extreme alone produces defensible recommendations. Self-reported data misses behavioral signals, while overly rigorous studies may lack the volume to generalize. The framework urges agencies to map each tool's position on the reach-rigor axis and deliberately pair them: use broad tools for discovery, then validate with rigorous methods. For example, a recent analysis of 107 million AI answers shows that citation gaps emerge when relying on a single source type, underscoring the need for triangulation. Agencies that balance reach and rigor build an insight engine that differentiates their strategy and withstands client scrutiny.

Frequently Asked Questions

Answers about pricing

Sunkcost is a calculator that compares the financial and operational trade-offs of running local AI models on agency hardware versus paying for cloud API tokens. It benchmarks model speed on specific machines, estimates electricity costs, and calculates the break-even point, the year when cumulative API savings exceed the hardware purchase price. Teams input their token usage, hardware choice, and local model, and Sunkcost returns a cost comparison, speed estimates, and shareable analysis cards.

Sunkcost offers 1 pricing tier, at $1000/mo (The break-even).

Technical founders and operations leads use Sunkcost to evaluate capital allocation for AI infrastructure. Project managers and engineering leads reference the speed benchmarks to assess whether local models meet latency requirements for coding assistants or document processing. Account executives may use shareable cost cards to justify infrastructure investments to stakeholders or clients.

Sunkcost saves 2–4 hours per month for a founder or operations lead evaluating local versus cloud AI infrastructure. Instead of building custom spreadsheets, gathering hardware specs, and researching API pricing, teams run a single calculation and receive break-even timelines, speed benchmarks, and cost projections. The time savings compound if your team revisits the decision quarterly or when evaluating new hardware.

Sunkcost is a standalone web calculator with no API or direct integrations. Teams export cost analysis cards as images or PDFs and share them via email, Slack, or internal wikis. The tool does not connect to accounting software, infrastructure platforms, or project management systems.

Sunkcost allows you to adjust token volume, input/output ratios, context window size, electricity rates, and API price decay assumptions in real time. The break-even timeline and cost projections update instantly, so you can model multiple scenarios (e.g., 'what if we double token usage' or 'what if electricity costs rise 20%') without re-running separate analyses.

Yes. Sunkcost includes pre-configured hardware profiles (Mac Studio M5 Max, DGX Spark, Strix Halo, etc.) with verified specs like memory bandwidth and power draw. You can compare break-even timelines across multiple machines running the same model, or run the same hardware against different models to see which combination minimizes cost and meets your speed requirements.

Sunkcost includes an 'API price decay' slider that models annual price drops of 20%, 30%, 40%, or 60% per year. If you select a higher decay rate, the break-even timeline extends, making local hardware less attractive. This helps teams account for competitive pricing pressure and avoid over-investing in hardware that may become uneconomical if APIs become cheaper faster than expected.
