As answered by people managing Finikit and JavaScript Tutorial.
Finikit's answer
Every calculator is 100% client-side JavaScript — no backend, no signup, no tracking. The FIRE Planner uses binary search (O(log n)) which is faster than traditional financial calculators.
Finikit's answer
Zero friction. Open a calculator, type your numbers, get instant results. No paywalls, no "create an account to see results", no ads.
Finikit's answer
Anyone making financial decisions — from beginners learning compound interest to experienced investors comparing products and planning retirement.
Finikit's answer
I built it because every financial calculator I found was either behind a paywall, covered in ads, or required sign-up. Started with 3 tools, now 37.
Finikit's answer
Vanilla JavaScript, HTML5, CSS3. Pure static site deployed on Vercel. No frameworks, no dependencies.
