You will get a custom HTML business calculator for pricing and profit
Project details
Calculating your product's cost, margin, or landed price manually every time is slow and error-prone. You will get a clean, interactive HTML business calculator that gives you instant, accurate results — no spreadsheets, no formulas to remember.
Pure HTML/CSS/JavaScript. No installation, no hosting required. Works in any browser, on any device.
TYPES I BUILD:
• HPP / Cost of Goods calculator
• Profit margin & selling price calculator
• Marketplace fee calculator (Amazon, Shopify, Shopee, etc.)
• Landed cost / import cost calculator
• Custom calculation tools for any industry
FEATURES:
• Instant real-time results as you type
• Mobile-responsive design
• Clean, branded UI
• Single HTML file — use offline or on any device
PERFECT FOR:
• E-commerce & marketplace sellers
• Importers, resellers & distributors
• Any product-based business needing fast pricing decisions
WHY WORK WITH ME:
I built and use these exact calculators in my own business. Every tool I deliver works in a real operational context — not just as a demo.
DELIVERABLE: Single HTML file + source code
