archie The invisible invoice — calculator

What's your number?

The document you received shows a range. This page computes your number: set your fees, rates and team below — everything on the right updates as you move the sliders.

Your project

What one staff hour costs you, fully loaded (not salary) — e.g. Budapest ≈ €15–30, Munich ≈ €60–90
Per hour, fully loaded
Measured: ~7 h/week for knowledge workers (McKinsey), 5.5 h in construction (FMI) — we default lower

This isn't new spending — it's hours your team already works, priced at your own cost rates. Four places it hides:

Archie answers your project's questions with sources, live — no canned demo.
Pricing scales with what it recovers: typically under 10% of the invoice Archie wins back on a project.

Model: hunt = search hours × team × weeks × staff rate. Echo = 2 leads × 3 h/week × lead rate. Drift = 7% of project hours as rework, 48% of it data-driven (FMI/Autodesk, Construction Disconnected), at staff rate. Late catch = one finding per project, ~400 h cross-discipline at a blended rate, capped vs. fee. Recovery rates (same as the deck): 50% of search time, 40% of senior interruptions, 40% of data-driven rework, 70% of late findings. The senior-interruption line is our assumption — no industry statistic exists; judge it against your own week. Sources: McKinsey Global Institute (2012): knowledge workers spend 19% of the week (~90 min/day) searching and gathering information. FMI/PlanGrid, Construction Disconnected (2018, survey of 599 construction leaders — contractor-side): 5.5 h/person/week searching; 48% of US rework attributed to poor data and miscommunication. Peer-reviewed research: total rework ≈ 12% of contract value, design-induced share largest (Love 2002; Burati et al. 1992). Get It Right Initiative (2016): avoidable error 10–25% of project value. US city plan-review records: 2–3 correction cycles are typical.
