Builds on the existing internal \"brochure-vs-platform / websites that do things\" brief — the foundational finding that the most-cited interactive-content conversion stats trace to a single vendor press release, and that no clean independent benchmark proves interactive site features convert better than static ones, is **treated as settled** here and not re-derived.\n\n## TL;DR — the honest verdict\n\nA customer-facing calculator can genuinely win work, and it can quietly cost you the deal. The conversion-stat case for one is **mostly vendor marketing dressed as research** ([[demand-metric-2014-interactive-content-survey]], [[outgrow-47-3pct-conversion-vendor]], [[cmi-2x-interactive-content-misattribution]]). The real reasons to build one are concrete and unrelated to those stats:\n\n1. Answers the only question every buyer is actually asking — *what will this cost me?* — at the moment they ask it.\n2. Qualifies and filters: a serious buyer who handed over an email after seeing a $40k estimate just self-identified.\n3. Disqualifies unprofitable enquiries before they eat your time ([[disqualification-via-public-estimator]]).\n\nAnd the real reasons NOT to build one (or to build only a directional range):\n\n1. **A wrong number is worse than no number** — anchoring is robust ([[anchoring-effect-tversky-kahneman-1974]]); a low online estimate becomes a hole you have to climb out of.\n2. **\"It's just an estimate\" may not save you** — detailed precise figures expose you to misrepresentation/negligence claims even when labelled ([[misrepresentation-negligence-detailed-estimates]], [[estimate-vs-quote-legal-distinction]]).\n3. **Calculators rot** — solar incentives can change daily ([[solar-incentives-change-daily-staleness]]); unmaintained calculators actively mislead.\n4. **Public pricing trains your customers to shop on price** ([[publishing-prices-competitor-exposure]]).\n\n## The decision tree\n\n**Build a calculator if** pricing is formula-driven, buyers comparison-shop anyway, you can keep inputs current, and you wrap numbers in an honest range with disclaimers — see [[rule-build-calculator-only-if-pricing-formulaic]].\n\n**Don't build one — or build only a *directional range* with no gate and a loud \"ballpark\"** — if pricing depends on judgement, a wrong number would poison your quotes, you can't commit to upkeep, or your edge is craft rather than cost. See [[rule-default-to-directional-range-ungated]] and [[rule-commit-to-input-refresh-or-dont-ship]].\n\n## The two stats every vendor will quote you (and why they're wrong)\n\n- The \"interactive content gets 2× engagement/conversions\" line traces to the **Demand Metric 2014 opinion survey of 185 marketers, sponsored by ion interactive** (a vendor selling interactive-content software, later acquired by Rock Content). It is **opinion**, not behaviour. See [[demand-metric-2014-interactive-content-survey]] + [[cmi-2x-interactive-content-misattribution]].\n- Outgrow's \"47.3% vs 2.8%, a 16.9× improvement\" figure is **the vendor's analysis of its own customers' 50,000+ forms** — not an independent benchmark ([[outgrow-47-3pct-conversion-vendor]]).\n- The closest legitimate academic work is **Häubl & Trifts 2000**, a lab experiment on decision *quality*, not website conversion ([[haubl-trifts-2000-marketing-science]]).\n\n## The speed-to-lead caveat\n\nWhatever you build, a calculator that fills an inbox you check on Mondays is wasted. The foundational lead-response data — the MIT 2007 study — found odds of *contacting* a lead drop ~100× between a 5-minute and a 30-minute response ([[mit-lead-response-study-2007]]). See [[rule-pair-calculator-with-five-minute-followup]].\n\n## Source-incentive meta-finding\n\nNearly every \"calculators convert\" source SELLS calculators, lead-gen SaaS, or calculator builds. Independent material clusters on the RISKS — law firms on liability, academics on anchoring, consumer/industry bodies on estimate accuracy. That asymmetry is itself a finding. See [[source-incentive-meta-finding-calculators]] and [[caveats-customer-facing-calculators-vendor-marketing-base]].\n\n## The article\n\nThe publication-ready prose draft of this brief lives at [[article-customer-facing-calculators-win-work-or-backfire]] (Candid /writing/ candidate, SMB audience).","rationale_body":"Compiled June 2026 to give Candid a clean, sourced position on customer-facing calculators that we can hand to SMB clients without parroting the vendor-laundered \"2× conversion\" line.
