ShelfWise Calculator — Bookstore Shelf Space & Profit Optimiser
What Is ShelfWise Calculator?ShelfWise Calculator is a polished, single-file web application for independent bookstore owners, managers, and buyers. It replaces gut-feel inventory decisions with a structured, four-step analysis workflow that calculates profit per linear foot by genre, recommends space reallocation, visualises an optimised floor layout, and produces a four-page branded PDF report — all from within a browser, with no login, no subscription, and no installation required.Who It's ForShelfWise is designed for independent bookstores between 500 and 5,000 square feet. It is equally valuable for: Owner-operators making day-to-day stock and layout decisions Store managers preparing for a seasonal rotation or refit Buyers reviewing genre performance before placing new orders Anyone who has ever thought: 'I know some sections earn more than others — but I have no idea which ones or by how much' The Four-Step WorkflowStep 1 — Store SetupEnter your store's total square footage, number of sections, monthly rent, and current monthly revenue. ShelfWise immediately calculates three live performance indicators: revenue per square foot, rent-to-revenue ratio, and average section size. A colour-coded health indicator flags whether your rent-to-revenue ratio is healthy, moderate, or a cause for concern.Step 2 — Genre AnalysisAdd each of your book sections — as many as you like — with their current shelf space in linear feet, average selling price, and monthly unit sales. ShelfWise calculates profit per linear foot for each genre in real time and colour-codes each one as a high, mid, or low performer. A live bar chart updates as you type, giving you an instant visual ranking of every section from least to most profitable. A 'Load sample data' button lets you explore the tool with pre-filled realistic data before entering your own.Step 3 — Optimization RecommendationsThis is the core of ShelfWise. Based on your genre data, it generates:📊Profit comparison panelThree metric tiles showing current monthly revenue, optimised potential (+22% industry estimate), and annual gain projection side by side.💡Five actionable recommendationsPersonalised to your data — naming your actual highest-earning genre to expand, your lowest earner to reduce, plus universal tactics covering eye-level placement, end-cap strategy, and cross-genre merchandising. Each recommendation includes an impact tag (High Impact, Quick Win, Low Effort, Strategic).📏Before-and-after allocation barsSide-by-side horizontal bar charts showing current space allocation versus the recommended redistribution for every genre, with directional arrows (↑ expand / ↓ reduce / → maintain).🗺️Recommended floor layoutA visual grid mockup of your store after optimisation. Each zone is colour-coded — green for sections to grow, red for sections to shrink, gold for sections to maintain and monitor. A register zone and entrance zone are included for spatial context.Step 4 — Seasonal PlannerA four-panel seasonal guide covering Spring, Summer, Autumn, and Winter. Each panel recommends the genres most likely to perform in that season — drawn from your actual data where available — along with a tailored merchandising tip for that period. A summary card shows your full optimisation story: current revenue, optimised potential, annual increase, and ROI, displayed in a clean dashboard with a circular ROI indicator.PDF ExportThe 'Export Full Report' button generates a four-page branded PDF and downloads it to the user's device instantly — no server, no upload, no waiting.
