24 alternatives to A private FIRE calculator suite that runs in the browser
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…

I launched NumPad v1 on here a few years ago, and back then it wasn't much more than a thin CodeMirror wrapper around the calculator engine I'd written. Now I've rewritten it as a PWA that supports multiple documents, persists them to IndexedDB, and has a syncing service for paying customers. Syncing is handled by Automerge[1] under the hood, which should make it relatively easy to get document sharing working too. [1] https://automerge.org/

Burner Note▲222In 2021 after getting thoroughly sick of Privnote, i built "Burner Note". Even though i didn't promote it in anyway other than a post here and a post on reddit, it ended up getting about 7000(ish) unique users per month. I kinda let it die about 18 months ago but i've resurrected it with some big upgrades. Most botable the app is now truly end to end encrypted (previously was just server side), and I've added dark mode as well as a few other bells and whistles. Feedback welcomed.

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…

Made this using Power BI and the Crypto Watch API. Started making this in November 2021, but never got around to publishing it, so that is the reason for the 'FOMO' in the title - probably a good thing if you 'missed out' on the crypto hype late last year. Now it serves as a way to see how much you 'saved' by not putting in money. Hope someone finds it fun!

Hey HN! I built a small app for comparing companies or job offers based on "years until financial independence" instead of "total compensation", after finding out the same offer from 2 companies can have a difference of years in terms of FIRE. I also ranked companies based on the time to FIRE as well. (with some assumptions, see the methodology for more details here https://firelist.io/methodology). It was useful for me, hopefully it's useful to you! I'll be adding more benefits and companies over the next few days or so. Let me know if you have any requests.

MoneyOnFIRE▲21We’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…
