Lovely interface. What does your tech stack look like?

To circle back and add a little more detail here, you'll notice it's mostly front-end (by design). In addition to Vue.js, Vuetify, Chart.js, and Firebase, I'm using some supporting modules like vuex, vue-router, threads, dayjs, and vuedraggable, among others. I also use web workers in several places, e.g. Monte Carlo mode, and for running all your plans on the dashboard without blocking the UI.

I've been dreaming of building this for myself (when I one day have time to do so) and seeing this is very exciting. I'll give it a shot and pay for it if it works well!

Feature request: make this an Electron app so I can actually use local storage, and feel safe that my data (and work) is safe and won't be wasted.

If there's anything you were hoping for that you find it's lacking, let me know!

Earlier quoted context omitted.

> taxes in the US are much better This is complicated. Taxes in the US are different. For example, a lot of higher earners are concentrated in California and New York, which have fairly high taxes; in New York or San Francisco a single person making $105k would take home about $75k (slightly less in SF, slightly more in NY) or about £3k more. I would suspect (but do not know) that the UK government pension and health…

That's income taxes; states aren't that different when you actually count "taxes" ie property, sales, income, and whatever else is left over. Texas is theoreti…

> Texas is theoretically a little worse for the middle class because property taxes are much higher. It's better if you're rich though.

I know they are higher in relative terms, but are they higher in absolute terms? I live in a single-family house in SoCal and pay over $12k/year in property taxes.

I wanted to build something like this myself forever, but decided to start by capturing my data over time into a Google Sheet, and in the end never ended up building it.

However, having that sheet meant I could enter in all my accounts, assets, debts into ProjectionLab in about 30 minutes, and spent the rest of the time fiddling with the projection tool, which far exceeds what I would have built.

The cash flow priorities I simply haven't found in another tool, and was one of the big reasons for me wanting to build my own, since I get about 50% of my total comp annually via RSUs vesting, bonuses and share sales, and route those directly into e.g. my mortgage.

Is there any chance to have the Pay Extra goals be annually (I mean, I can do N/12, but annually probably is more accurate from a charting perspective).

I've never forked out my credit card so quickly, well done.

Awesome idea!

One bit of feedback:

I found the timed accordion about your product to be distracting while I was reading. I felt pressure to read quickly and concentrate, which I’m guessing was the intended effect.

However, I’m a parent of two young children and have a slightly intense job, so my days are filled with time pressure already.

The added stress to read something when I’m trying to explore your content at my own pace produced a net negative experience for me.

One way you might resolve this is by giving users some sort of a “pause” button or opt out.

The reason I spent the time to give you this feedback was because I recognize how hard you must have worked and appreciate the effort you’ve obviously put in. Nice work!

Thanks so much! Comments like this are a big part of what makes it possible for me to keep consistently carving out the time on nights/weekends :)

And to your point on data entry, I should probably go back and look at all the forms and make more of the inputs multi-type so you can always specify in whatever frequency you like.

Great point on the accordion; last thing I want to do is add anxiety! If you hover your mouse over the section you're reading, the countdown should stop... but perhaps I should get rid of the auto-advance altogether?

Let me add to the enthusiastic chorus with my own "This is great!". One thing that I feel you can do better (and forgive me if it's already there, in five minutes of poking around I couldn't find it) is a knowledge base of some sort. While I was building a model I wasn't sure what reasonable values would be for some of the knobs and stuff that I might be missing. Basically, I think that you could link to existing articles or pointers on personal finance that could help me, a complete novice, model better.

Also, and maybe this is a non-goal, you could help me optimize - let's say I've set my living expenses to $X/mo and income to $Y/mo, and I've set a goal for financial independence by age A, the model could suggest things I could do to achieve that goal, say by cutting X down to X' or putting more of Y into a different kind of savings account. It might not be easy to do, but again, as a complete novice I'd really love to get a plan that didn't require days of work to set up.
