I will try this out!

Currently the gold standard for this kind of FI simulation is OnTrajectory. There’s a learning curve but it’s so much more comprehensive than any spreadsheet you could build. I consult it every time I make a big decision.

Get in touch with your email and I can provide a referral link.

> (there is also a button to remove all your data at a later date if desired) Do you keep database backups?

Currently, no. I suppose one could criticize that from an operations perspective, but at least data requested for deletion does really go away.

Not having a recovery plan is bad. You should have backups but with lifecycle rules that remove them after x days.

So I have a Google Sheet that basically does this and I tested this out and got some similar numbers as my sheet, so some things seem to be working well! This is also a great UI!

I was pretty impressed with the depth of detail as well, and one thing this seems to have better tooling for than my manual sheet is for tax treatment and long term tracking there

Two bugs/issues I found:

1. I couldn't tell if inflation was applied in future years at all. Despite selecting an increase in income and inflation matched expenses, neither seemed to be reflected when I selected the future year.

2. Setting 401K by percentage caused lots of issues as it allowed me to go over the IRS limit. I just wanted to set it by amount and be done with it! Would be good to have options to allocate savings like that as well as by percentage.

Honestly, this is really intriguing for me as I've covered a lot of these cases and as a developer I've thought about the UI/UX for this but basically have always thought that the edge cases were so vast that it would be hard to get users while also making sa reasonable UX. Truly, using this changed my mind and this seems like something that could be possible. I'm not sure what your team size is and I have limited time, but I'd be interested in talking and seeing if there's any way to contribute / help here! Feel free to contact me @gmail or via my bio's website contact form if you're at all interested in that!

For every person that cares about privacy, there are 10,000 that don't. That's why it's so profitable to be an evil data hoarder.

How is data hoarding evil? Data lets us improve things, know what services need to be made, connect everything better. There's potential for abuse as in anything but we don't call cough syrup evil.

I like the analogy and agree with you but the potential for abuse of cough syrup is for the user, not the manufacturer.

Maybe another analogy would be like if you had to give your full banking information to every restaurant your family dines at?

Looks interesting, but based on the privacy policy terms of data usage, transferability, and so forth, I can't in good faith test with real financial data: https://projectifi.io/privacy-policy.html Everytime I see a tool that shouldn't need to be hosted remotely as a service and could reasonably be deployed to the client where they have more control over their data (not as a service), it's a non-starter for me. I get…

I agree. The trend of handing over all your data ( especially your financial data) to some nebulous service isn't exactly my favourite. Which is why I built https://ufincs.com , a nebulous service where you hand over all your financial data! Yes, that was a joke. In reality, uFincs is more of a stop-gap between what you seek (native app where you own the data) and what the status quo is (web-based app where your data…

ufincs looks very cool! During my December holiday, I was thinking of making a web-based platform that had a more modern UI than GNUcash, and it looks like you built it already!

Just curious, what's your tech stack, how long have you been working on it, and how many users do you have?

There is no reason at all for this to be server-hosted. I have of course done this for myself a very long time ago creating an effectively identical feature set using spreadsheets and even put them onto Microsoft's sharing pages (no idea what happened to them, it was such a long time ago). I'm not saying this isn't a better solution than Excel. You work with what's available at the time. But there is nothing at all a…

Let me just say that I'm glad people like you and Frost1x are here, fighting the good fight. Ten years ago, I still though the "make an app on the web" thing was a fad that would go away soon, and the pendulum would swing back to native apps. That hasn't happened, and if anything, the practice of just putting it on the web has become the default, which is a little scary. The web site looks great, and I sincerely appr…

The problem is that everyone making something like this wants to have at least seven zeros in their bank account when they cash out after 5-10 years - selling licenses to a desktop app doesn't get you that.

One thing I've always struggled with in these "financial planning" products is how to make the numbers make sense on a gut level. My problem is that, after doing some level of "taking charge of my finances" to make a savings/investment plan, it still feels like I'm treading water and barely making any progress toward my goals. Yet when I plug my numbers into any financial planning app (including this one), they inevi…

Yes. And these tools will always provide significantly inacurate forecasts, I think, because 1/ it is hard for humans to predict their spending habits, since spending often increase proportionally to income, and not just inflation. 2/ most people have a very different path ahead of them, along with so many unknowns in the equation.

That's probably why people serious about their money consult a professional, who has hopefully historical data at hand and in his head, who produces a forecast, each year, that is very tailored to the person, the person's personality, habits, job industry and many other important factors that a financial planer coded with if and else, avg and linear projection etc can't match. Maybe machine learning can get decent results of training properly on very good data sets.

And about most planners showing we will be millionaire in a few years, I'm tempted to say it's for the exact same reason demo data and screenshots for a CRM or analytics system always tend to display over optimist income/sales.

I wanted to like it but I live in the EU and it's too focused on dollars.

Good point. Currently it's tailored more towards the US, but I'm hoping to find time to add features for other locations. That said, the idea of supporting every tax system out there is probably a bridge too far, but simple things like being able to switch currencies seems quite doable.

Do you pay for desktop software though? Such tools could be built for desktops-first with no data ever leaving the machine, but people will scoff at paying for them...
