Claude Code Financial Tools Template Pack

The Claude Code Financial Tools Template Pack gives you 15 production-ready financial calculator components built with React 18, Tailwind CSS, and TypeScript. Each tool follows the exact architecture pattern used on wowhow.cloud, comes with complete SEO metadata and JSON-LD schema markup, and drops straight into any Next.js App Router project. Two fully implemented tools (Loan EMI Calculator and SIP Returns Calculator) are included with full source, plus 13 additional tools with scaffolded structure ready for your implementation.

What You Get

• Loan EMI Calculator — Fully implemented React component with live EMI calculation, amortization schedule table (first 24 months), principal vs. interest breakdown bar, and INR/USD currency toggle. Complete with metadata.ts and schema.ts.
• SIP Returns Calculator — Fully implemented component with monthly SIP inputs, expected return rate slider, year-by-year growth table, and maturity value display with wealth growth visualization.

• Scaffolding Script — scripts/add-tool.sh scaffolds a new tool from the EMI Calculator template in one command: ./add-tool.sh my-tool "My Tool Title".
• SEO Pattern — Every tool has a metadata.ts with 50-60 char title, 140-160 char description, OG tags, canonical URL, and a schema.ts with WebApplication + FAQPage JSON-LD (3 questions each).
