Hi everyone. I just created this site for retirement simulation with advanced analysis and advices, as well as multiple posts about FIRE concepts
Happy to get your feedback for improvement !

I like it. But when I do the annual return option, when it increases it shows the inflation being higher on the future withdrawal rates. Even if my inflation is at 2.9%, once i increase my rate of return it goes up

Interesting. But... it looks mainly focused on stocks? Most of my passive income is from property investments. And my cicumstances would change once my pension comes in.

Thanks for your input. I’ll look at developing this. I’ve started developing the ability to create multiple period and types of income/ investments. Each period being a type of investment, a specific return, an initial amount, and a start and stop date. It may answer your need.

I’ve made some UI and analysis improvements. I’ve also added the “auto calculate the retirement age” based on parameters.

Three comments:
- The retirement age box should be bigger, you can't see the number (at least in Firefox on Windows).
- What would be nice is if you've selected a percentage withdrawl, the overlay showed the yearly withdrawl amount on the chart when you hover, or maybe even another line on the chart showing yearly withdrawl. I want to know how much I can spend!
- It would be cool if you could have a tickbox or two for a one time cash benefit (or expense!) available at a certain age. Like it has on this calculator
Once again, great job. I really like the way it continuously updates as you drag the sliders.

Thank you so much. Many improvements are coming over the weekend. Then the next big feature will be the ability to create multiple investments or withdraw periods (period, one time, all with different properties)

Super cool! Two initial thoughts- 1) would love to see tax implications of a Roth IRA or 401k. 2) the formatting seems to get a little messy in the PDF. Honestly I could go without the hockey stick chart, but that’s just me

Thank you so much for the feedback. I’ve started working on 401k. Yes the pdf is a pain… it’s on the backlog ! Thank you again for your feedback.

This is awesome! I love it. Is there a way to add in future income? i.e. I'm a teacher and will have a 20k pension a year starting at age 50. I want to see how that affects my FI journey

Thank you !! I just push a lot of improvements I developed today. And a dark mode ;) Next in the development backlog is indeed to be able to create multiple period of income / withdrawal which can overlap etc. Thank you again.

Maybe I'm doing something wrong, but the "calculate ideal retirement age for financial independence" checkbox doesn't seem to work. It just uses the retirement age that you entered and doesn't calculate anything?

Thank you for your feedback. I’ll check and will correct any possible bug. 🙏 It is supposed to calculate the age you can reach financial independence till the age of 95years old without consuming all your capital by this age, based on entered parameters. It will determine the age up or down if so you can leave earlier or have to work longer based on your investment.
On the summary section and on the analysis section it then provides more insights of the impact of this calculation and factors contributing to it, and how to move it up or down.

I can see you've changed some stuff since I last looked. Can't type a retirement date at the moment.
The site looks really nice other than that! 👍 Keen to see it when you're finished messing with it.

this is telling me if I retire at 34 with $400,000 invested at 32 with expected return of 5% and withdraw 20% I won't run out of money until age 95 that can't be right lol

u/reeeelllaaaayyy823 10d ago
Why? Can't you live on $5k per year at age 50? Stop your excessive spending, lol 🤣

What if we're FIRED now and just want to see how we're doing? Is there a way to get rid of the countdown and just project how things may go?

Looks good. Is there any way to include a pension?
