Website Marketing Calculator
Website Marketing Calculator helps coaches and course creators model the economics of a marketing funnel — from ad spend to booked calls to enrolled clients — in two directions: forward from a budget, or backward from an income goal.

Highlights
- Budget mode: ad budget + cost per lead → projected leads, bookings, calls, clients, revenue, and profit.
- Income mode: income goal + profit margin → the required clients, calls, bookings, and leads, unwound backward through the funnel’s conversion rates.
- Five-stage stepper (Program, Funnel, Projections, Advertising, Metrics) with clickable headers and a first-run training popup; live metrics include ROAS, max cost per lead/booking/call/client, conversion rate, and gross margin.
- Real-world discreteness: floor on forward counts, ceiling on backward counts — no fractional leads or clients.
- No build step: single-page Vue 2 + Vuetify 2 from CDN, deployed to GitHub Pages by a single workflow.
