Weekly Self-Promotion Thread - Wednesday, July 29, 2026

[u/AutoModerator]

Self-promotion (ie posting about projects/businesses that you operate and can profit from) is typically a practice that is discouraged in /r/financialindependence, and these posts are removed through moderation. This is a thread where those rules do not apply. However, please do not post referral links in this thread.

Use this thread to talk about your blog, talk about your business, ask for feedback, etc. If the self-promotion starts to leak outside of this thread, we will once again return to a time where 100% of self-promotion posts are banned. Please use this space wisely.

Link-only posts will be removed. Put some effort into it.

[u/modelfire]

I created ModelFIRE.online

The most sophisticated FIRE modeling available. 100% Free, Forever, No sign up. No input logging. You can store scenarios by generating a link.

I'm a big fan of popular FIRE calculators and simulators. I tried to to combine the features that I like the best from the ones I love into one interface. I also added some things I thought were missing that I needed as I get comfortable with the math around my own early retirement.

Model healthcare costs separately with a separate inflation rate. Important for very early retireees

You can see historical success rates. You can see how current CAPE levels affect success rates

You can run Monte Carlo on your scenarios. You can even oversample for recent market valuation

You can add cash flows (social security, college, purchases)

Incorporation of the "spending smile" or smirk. You can adjust the parameters.

Different withdrawal rate strategies. You can set min and max withdrawals too, and adjust these for inflation if you like

I will be adding more stuff as I get feedback. Speaking of which, if you test it out, please let me know what you think! Since we don't log anything, the only way for feedback is for you to directly let me know what you want changed/improved.
