Hey David, since ProjectiFi only pulls money out to cover the expenses/needs defined in your plan, how do you see that integrating with these withdrawal strategies? Let’s take the simplest case of 4% rule....if you select that as the notional drawdown strategy, but then there are expenses in your plan requiring more (or less) than 4% withdrawal in a given year....what should happen?

Would this be like a separate exploration mode where all your defined expenses are just ignored and money withdrawn is assumed to be gone? (if so, it would probably need an input to specify when to start doing this in the simulation, maybe with a milestone binding?)

Let me know what you think!

Also, since Changemap’s notification system is practically non-existent, feel free to socialize ideas like these on Discord/email first; I’ll see them faster and more reliably that way.

Hi Kyle, all good thoughts and yes I see your point on the variable expenses which could make it tricky.

I guess I was thinking that this would be a test to see if one particular strategy would succeed or fail based on meeting the expenses over time, but is that really a good measure if you have let’s say one year with a car purchase where the 4% doesn’t cover it, but the rest of the time it does?

I think I was curious if different withdrawl strategies would effect the success or failure of a monte carlo run, but I admit I’m over my head on how exactly that would look. I assume in years that you had to withdrawl more than a strategy allowed, then the question is what is the impact if you continue to use the strategy moving forward.

I’ll checkout Discord, so I don’t clog up your Changemap :)

I would really like this feature, specifically with enough granularity to do a ratchet strategy ala Kitces.

It’s kind of fundamentally a different model from the current expense-driven model, but I don’t think that means it wouldn’t be super useful. My initial thought would be you would ignore the expenses, but if you’re mapping the withdrawals, you could overlay the expenses on the graph just for a reference.

Just pushed an early draft of the new Withdrawal Strategy mode to the beta site: https://projectifi-201a2–dev-xsmyy9im.web.app

A) what do you think? B) what other classic strategies (and/or config options) would you like to see?

Also posted an update on this to discord, so feel free to reply there.

I added Kitces’ Ratcheting Safe Withdrawal Rate as well, so if you take a look, let me know if this is what you were hoping to see!

Thanks, this is great, exactly the kind of thing I was looking for. It really helps to show how different withdrawal rates or approaches could significantly change the future planning, so this is perfect. Thanks for making it happen!
