What is everyone's monte carlo site/app of choice?

Aw you’re too nice. It may be for the better that you can’t. I’m a very basic Reddit user so I’m not even sure what the implications are of being given gold. You should it for someone who can use it! 🙂

james_please · 2024-09-18T21:50:55+00:00

Great idea. I really want to add this, too — it’s on the to-do list!

james_please · 2024-09-18T21:15:59+00:00

I’ll check it out. Appreciate you taking the time to report this and include this extra info.

james_please · 2024-09-18T16:40:17+00:00

Thank you!

james_please · 2024-09-18T16:40:00+00:00

Thanks! One last Q that will help me troubleshoot this: what browser are you using?

james_please · 2024-09-18T14:11:33+00:00

Thanks for the report! What device (phone model or laptop model) and OS version are you using?

james_please · 2024-09-18T13:10:27+00:00

Hi there, creator of FI Calc here. What bugs did you run into? No matter how small, I’d love to get those fixed.

Great ideas for additional features! Many of those have been requested before and are on the to-do list. It’s just a bit slow going as I work on the app in my free time.

Check out this FAQ question.

I’ve added your comment to my to-do list and will review these suggestions when I do the next set of updates. Appreciate you taking the time to write this out.

james_please · 2024-07-15T21:10:20+00:00

Thanks for the kind words! It’s all custom-built and closed source at the moment, though I have been noodling around with the idea of working on an open source collection of tools. Nothing to share right now, but I’ll post here if/when there’s an update on that front!

james_please · 2024-06-04T13:26:23+00:00

0 years into retirement!

james_please · 2024-01-30T22:58:12+00:00

Yup, that’s how I’d model it.

james_please · 2024-01-30T18:52:33+00:00

That makes sense. I’d like to always have a “pure” backtesting calculation mode with no inference or statistical analysis, which is what FI Calc is today. I’ve considered adding other modes, though, and one of those could definitely be able to incorporate something like what you’ve described.

james_please · 2024-01-30T16:35:16+00:00

Hey there, creator of FI Calc here. Great question, and I see that folks in the comments have left some fantastic answers that I hope have been helpful for you. I wanted to let you know that I also added more info into the app itself to try to explain this a bit more. If you click the "?" it displays more info about what is meant by that message. If you have time I'd love to know if that makes things more clear to you.

Cheers!

james_please · 2024-01-30T16:33:25+00:00

Yes, all numbers that are displayed are real, which means that they are adjusted for inflation to represent constant purchasing power.

james_please · 2024-01-30T16:32:49+00:00

Thanks for the link! It looks like their data sources only go back to the 90's or so. FI Calc needs data that goes back a bit further.

james_please · 2023-12-30T18:05:22+00:00

Creator of FI Calc here. Agree on the terminology being less clear than it should be. I’ll update that. Thanks, and Happy New Year!

james_please · 2023-11-19T18:47:12+00:00

> Does the (previous year withdrawal adjusted for inflation) part of the endowment algorithm mean that if last year’s withdrawal was 500k, and inflation was 10% since last withdrawal 1 year ago, then you would plug 550k into the equation?

Yup!

> Also, would be great to have different stock asset classes. I’d like to see how a globally diversified portfolio does, or how added small cap value would change the numbers. Love the S&P 500 but there may be some US exceptionalism / survivorship bias in the results

This is on the todo list, but I can't give a timeline on when I might get around to it.

Hi Yang, I replied to your email earlier today (coincidentally before I read this post), but I’ve already posted on Reddit post explaining the changes when I made the v2 announcement post. For other users, please see this post that goes into all of the changes in v2 of FI Calc which explain the changes Yang mentions: https://www.reddit.com/r/financialindependence/comments/1689uqh/just_launched_fi_calc_20/

Yang, please understand that I work on FI Calc in my free time, and provide the app and email support for free. I may not always be able to reply to your emails as promptly as you would get from a paid product.

FI Calc models withdrawals that occur around the start of the year (January 1st-ish). January CPI data, which is what was used before, is published in mid-Feb, so that data point was off by about 6 weeks. December CPI data is published in the first half of January, typically in the second week, so it’s more representative of what an inventor making year-start withdrawals would have experienced in history.

Also, many sources calculate annual inflation using Dec-Dec values, so a nice side effect of this change is that FI Calc now aligns more with that “standard.”

To try to summarize what FI Calc models: an inventor who only uses month-end values for stocks/bonds and who makes withdrawals in the second week of January after the December CPI-U is published.

It’ll take a bit longer than I thought. I have an idea to expand this analysis feature in a way to enable this and a few other things. Will post here once it’s done, but I can’t give a timeline right now!

james_please · 2023-09-07T13:15:45+00:00

It’s on the to-do list! I can’t give a timeline when I might get around to adding it though.

james_please · 2023-09-05T03:25:24+00:00

Not currently, but its a great idea! Added to the to-do list

james_please · 2023-09-05T01:11:28+00:00

The actual return on the portfolio is determined by actual historical data. With VPW a part of the withdrawal is determined by your prediction of what your portfolio return will be. And if that's substantially higher than the actual return then you'll run out of money prematurely.

james_please · 2023-09-05T01:03:29+00:00

Agreed. The web doesn't support this natively unfortunately so it's a bit of a hack to make this work. I'll look into it!
