I Built 53 Free Trading Calculators – Here's What I Learned

As a forex trader, I was constantly switching between different calculator tabs while managing trades. So I built TradeCalc — one site with every calculator a trader needs.

What it does

TradeCalc has 53 free calculators covering:

• Forex — Position size, pip value, profit/loss, margin, spread cost, swap
• Risk management — Risk/reward, Kelly criterion, risk of ruin, drawdown
• Prop firm — Trailing drawdown, daily loss limit, consistency rule, profit target
• Futures — Tick value, funding rate, roll cost, commission, liquidation price
• Crypto — Liquidation price, funding rate, crypto profit
• Stocks — Dividend yield, stock profit, CAGR

Tech stack

• Next.js 16 (static export)
• TypeScript
• Tailwind CSS v4
• Deployed on Cloudflare Pages

What I learned

1. Static export is underrated — 53 pages, zero server costs
2. SEO takes patience — structured data and semantic HTML matter more than tricks
3. Traders want simple — no sign-up, no ads, just fast math
