Most "calculators" online are ad-heavy, English-only, or don't show their formulas. So I built one that runs entirely in the browser.</p> <p><strong>Live:</strong> <a href="https://8cpc-pension-calculator.vercel.app/" rel="noopener noreferrer">https://8cpc-pension-calculator.vercel.app/</a> (Hindi: <a href="https://8cpc-pension-calculator.vercel.app/hi/" rel="noopener noreferrer">https://8cpc-pension-calculator.vercel.app/hi/</a>)</p> <h2> What it does </h2> <ul> <li>New basic pension at every projected fitment factor (1.92 to 3.833)</li> <li>DA/DR with arrears, family pension, commutation and 15-year restoration</li> <li>A page for each pension amount, e.g. <a href="https://8cpc-pension-calculator.vercel.app/pension-25000-8th-pay-commission/" rel="noopener noreferrer">₹25,000 pension in 8th Pay Commission</a> </li> <li>Every figure linked to official orders (PIB, DoPPW, Pensioners' Portal)</li> </ul> <h2> How it's built </h2> <ul> <li>Plain HTML generated by a small Python build script: no framework, no runtime server</li> <li>Vanilla JS for the calculations, so nothing leaves the user's device</li> <li>A full server-rendered Hindi counterpart for every page, with reciprocal hreflang</li> <li>Strict CSP, JSON-LD (FAQPage, WebApplication), a sitemap, IndexNow pings, and llms.txt for AI crawlers</li> <li>Deployed on Vercel from GitHub, with tests run before each push</li> </ul> <h2> Lessons </h2> <ol> <li>Server-rendered language versions beat JS toggles for SEO.</li> <li>Showing the formula and its source builds more trust than a fancy UI.</li> <li>Keep titles under 70 characters and descriptions under 160. Bing flags both.</li> </ol> <p>I also built <a href="https://yt-policy-shield.vercel.app/" rel="noopener noreferrer">YT Policy Shield</a>, a free YouTube monetization-policy and AI-voice risk checker, with the same static approach.</p> <p>Feedback welcome!</p> webdev javascript seo showdev
