Every few years I see this posted on HN. Every time I play with it. Every time I am delighted by it. Every time, I think I'll use it. And then I don't.

To be fair, my finances are simple to a fault, so I haven't felt like using it. But, once things ramp up, this will be the first tool I subscribe to.

It's a great tool. I recommend.

Me too! haha. I only added those after a bunch of people requested them. If you dismiss them, they don't reappear do they? They shouldn't at least...

I had it reappear 3 times when I was trying it out moving between pages. First time was before I created an account though in the sandbox. Not sure exactly the replication steps for the second and third time it showed up.

A complicating factor is that there are at least 2 different tours for different sections of the interface (e.g. high-level dashboards vs plan interface).

Do you think it would be better to infer from one tour dismissal that a user never wants to see another tour for anything else?

Anything you feel the tool is missing that might make it more compelling?

Personally I use it more on a monthly or even quarterly basis to consider new decisions, update stuff, etc. That fits with the usage pattern I initially imagined for a long-term planning app, but I'm always open to other ideas.

P.S. I started working on PL in 2021, so we're not quite in "every few years" territory yet ;)

I just had a play around with this for the first time in a long while (I tried it when it was projectfi), and it's in a really great place - well done! Love that you support countries other than the US - that's very much appreciated. What I find when setting up long-term plans like this is that you realize just how much key life decisions affect the outcomes, along with how much uncertainty I have over those life dec…

Thanks for playing around with the new version! And sounds like it's a good thing I rebranded to ProjectionLab -- that first 'i' in ProjectiFi was way too easy to miss ;) Is there a certain direction you'd like to see me take the tool from here?

One thing I'd like to see is a better way to estimate the cost of kids, and specifically per-child. If I could just click a button and have the average cost for a child for my country added from a certain year, that would be awesome.

What browser/OS? (unless you'd rather not share, that's fine too). I just re-tested chrome, safari, and firefox on Mac OS and seems like the close tab warning works as expected. That being said, it's always possible there's some specific flow that's not handled properly, so I'd be curious to hear more details if you remember. To clarify what I meant on the recovery mechanism, the current implementation is what folks…

It was Win10/Chrome. Definitely did not see a warning (though I was aware that the data would be lost.)

I don't remember the exact working. Did it explicitly mention the free trial in the data recovery dialog?

> My guess on effective tax rate is it was likely including property taxes. Adding those to the numerator during retirement when taxable income is usually lower could drive up that number.

That's possible. I didn't fill anything related to property taxes, so it was probably implied? With CA proposition 13 (which caps the property tax increase), the property tax on rentals will be low compared to property value when you've owned the property for decades (as would be the case when you're in retirement.)

wow this is so nice! somebody tell the bogleheads. they'll let you know if anything is missing ;)

A while back, I asked the bogleheads mods if it would be a good topic for a forum thread or the wiki. At the time, I think the fact that I was asking as the creator may have been a turn off.

But it seems like at some point they added it to this page at least: https://www.bogleheads.org/wiki/Retirement_calculators_and_s...
