Products that do what A private FIRE calculator suite that runs in the browser does
Hi HN, I built Firenum because most FIRE calculators I found were either too simplistic or required uploading my entire financial life to a third-party server. I wanted a comprehensive suite that could model more than just the 4% rule. This tool handles Coast, Lean, Fat, and Barista FIRE, but more importantly, it lets you model 'what-if' scenarios like market crashes or major life events to see how they impact your timeline. Key features: -> Privacy-First: No signup required. All calculations and data persistence happen in your local storage. Nothing is sent to a backend. -> Scenario…

Most retirement calculators either oversimplify things or ask you to link your accounts so they can make money off your data. I wanted something that actually helped me see if I was on track without handing over a bank login, so I built RetireNumber. It's a privacy-first retirement planner. You type in your own numbers. No account linking, no selling your data, no VC. Just me and a subscription. The engine does real math: Monte Carlo with 1,000 runs, historical backtesting to 1928 using Shiller's Yale data, tax-aware withdrawal strategies, and scenario comparison so you can try different…

Hey everyone! After another year of building as a solo dev on nights and weekends, I'm back with an update on this post: https://news.ycombinator.com/item?id=31083093. TL;DR - ProjectionLab (https://projectionlab.com) is a privacy-friendly personal finance planning tool where you can create financial plans that go beyond the standard online retirement calculators. And by popular request, it now supports self-hosting for Lifetime users! Something I'm grateful for is that our community here on HN is the difference between PL existing and not. There was actually a time…

I figured I needed to work on my coding skills before building the next groundbreaking AI app, so I started working on this free tool site. Its basically just an aggregation of various commonly used calculators and unit convertors. Link: https://www.calcverse.live Tech Stack: Next, React, Typescript, shadcn UI, Tailwind CSS Would greatly appreciate your feedback on the UI/UX and accessibilty. I struggled the most with navigation. I've added a search box, a sidebar, breadcrumbs and pages with grids of cards leading to the respective calculator or unit convertor, but not sure if…

We’re Scott and Sunny—two long-time personal finance nerds. When we met 6 years ago we compared our personal finance spreadsheets. Ours were packed with macros, scenarios, and tax modeling—but even then, found they were not complete. Planning for financial independence is hard, and the cost of mistakes is high. So we built the tool we always wanted: MoneyOnFIRE. MOF calculates a personalized, tax-aware roadmap to financial independence—across account types, life goals, and withdrawal strategies. It shows you not just if you can achieve financial indepdendence, but how, when, and what to…

Hi HN, I am a solopreneur in the evenings and a software engineer during the day. In the past, I have created lots of calculators for my web projects and freelancing friends. These were pretty basic, but users always welcomed them. I also used currently available builders, but the problem was that they were either slow, broke on mobile devices, had nonsense page view limits, or were expensive. Some even ticked all those boxes. So I have decided to create my own, with a simple interface, and called it Creative Widgets (if it ever takes off, I plan to add more exciting stuff like charts, etc,…
