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…

Here's a little side project I’ve been working on: https://totalrealreturns.com/ The Total Real Returns chart demonstrates the preservation or growth of real wealth more clearly than conventional (nominal-dollar, price-only) stock charts, because: (1) we include the effects of inflation-diminished purchasing power, and (2) we include the effects of reinvesting dividends from the initial investment. I found it harder to explain the y-axis in words than it was to do the math, so please let me know if you think the "baguettes" explanation on the homepage helps. I was up until 4am…

Quick background: I used to code. Studied it in school, wrote some projects, but eventually convinced myself I wasn't cut out for it. Too slow, too many bugs, imposter syndrome — the usual story. So I pivoted, ended up as an investment associate at an early-stage angel fund, and haven't written real code in years. Fast forward to now. I'm a Buffett nerd — big believer in compound interest as a mental model for life. I run compound interest calculations constantly. Not because I need to, but because watching numbers grow over 30-40 years keeps me patient when markets get wild. It's basically…

Read the Tape gives players the same 5 S&P500 stock charts per day to predict. You select low, medium or high confidence and then call the chart UP or DOWN. It's a 1d chart which then resolves over 5 days. Alpha is scored against the Monkey Index, a basket of 11 random coin flips at low confidence which provides a tangible win/lose condition. We're two weeks in and some interesting data is being kicked up. Players like to call tops even though stonks go up- 60% of the 70 charts so far resolve higher, players' down calls have only been right 31% of the time. There's a full stats dive at…

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! I'm back with an update on this post [0]. Last year, I quit my corporate job and went full-time on ProjectionLab, the long-term financial planning app I've been building for the past 4 years, which some of you may recognize. The decision to go all-in felt like a huge leap. But it was the right call, and it's been a good year. And without the HN community, it would not have happened. As I mentioned last time [0], the feedback on my original Show HN is THE reason I'm still here working on this. I'm really grateful for that. And I hope the way I’ve grown PL -- staying bootstrapped…

Hi HN! I've been working on this calculator for some time now. It started off as a tool to help me do some retirement planning and I think it could be broadly useful to others as well. It's very generic, which is both good and bad. Good, because you are not beholden to the assumptions of the model, like in many other calculators. This also means that it’s not US centric. On the other hand, you do need a bit of financial planning knowledge to be able to use it effectively. There are many retirement calculators out there -- here's what I think The Tortoise does better than most: 1. An easy to…
