Agency project quote estimator
Mirrors how quote tools work in the wild: scope first, labor rate second, rush last. Calclet supports sliders, tiered selects, and multi-step flows so your AI-built calculator can match your discovery process.
Example scenario
A digital shop prices a Webflow relaunch with 12 unique page templates, using the “Standard” design + build complexity band at 10 hours per page (componentized sections, light motion, no bespoke WebGL). Four integration and custom-logic blocks—for example HubSpot forms, member-gated resource download, events feed, and GA4/Tag Manager hardening—add 4 × 10 = 40 hours to the 120 page-build hours, for 160 sellable hours at a $165 blended delivery rate. A 1.1× rush factor (tighter launch window, weekend cutover) multiplies through to an indicative project total of about $29,040 before management reserve, retainer change orders, or third-party license pass-throughs.

How to run the agency project quote wizard
- On Scope, count distinct templates or routed layouts buyers actually approve—not every CMS variant—then pick “Design + build complexity” to match your rate card (template-heavy 6h, standard 10h, custom/animation-heavy 18h per page).
- On Build, add one integration / custom-logic block for each meaningful systems touchpoint (CRM embed, checkout edge case, middleware, custom API read) because each block here maps to 10 budgeted hours in the model; set “Blended hourly rate” to your published sell-side rate, not fully loaded cost unless you price cost-plus.
- On Timeline, raise the rush factor when the client compresses UAT, needs a hard event launch, or wants parallel workstreams; keep 1.0× when the schedule matches your lead-time policy.
- Read “Indicative project total” as a sell price floor before PM overhead, account management, or fixed-fee risk buffer—layer 8–15% contingency for net-new clients or unclear content readiness.
Agency build estimate & rate benchmarks
- Representative U.S. digital shop blended billable rate (design + dev mix, non-coastal adjust down)
- Often ~$130–$220/hr at maturity; premium brand or productized Webflow/Shopify specialists land higher
- Template-led marketing-site build (content + system pages) — hours per unique template
- Commonly ~6–12h for template-heavy; 15–25h+ when motion systems, CMS relationships, and QA surface area expand
- Rush or expedite multipliers on fixed-fee SOWs (industry practice band)
- Frequently 1.10–1.30× on labor when calendar compression forces overtime, weekend deploys, or parallel workstreams
Best use cases
- Growth and performance planning
- Budget and forecast scenario modeling
- Client-facing pre-qualification and education
Frequently asked questions
Why does each “integration block” assume 10 hours—my HubSpot form took 3 hours last time?
The model uses a flat 10h block to cover discovery, environment differences, schema testing, and handoff—not just the happy-path embed. If your shop standardizes headless APIs, recalibrate by treating a small integration as a fraction of a block in your own rate card, or fork the calculator to match your internal point system.
Should “unique pages / templates” include modals, blog post template, and email capture variants?
Count user-facing layout surfaces the team will design, build, and regression-test in scope. A shared blog article template is one page; three distinct long-form story layouts are three. Aligned definitions with the client SOW prevent under-quoting by 20–30% on content-heavy sites.
Is blended hourly the same as my cost rate times target margin?
No—blended hourly here is the client-facing sell rate that covers salary, overhead, and target margin. If you accidentally input internal cost, the quote will be unprofitable even when the hours math looks right.
How do I reflect a fixed retainer with a not-to-exceed cap instead of time and materials?
Use the calculator to build the hours-time-and-materials equivalent, then cap the total in the contract. The rush factor still signals internal opportunity cost when the cap compresses your margin.
