Withdrawal calculator

[sigpros]

I have looked around online but can't find what I want. Is there a calculator that you can input your 401K value, age, and see how much you can withdrawal while changing interest rate?

Example:
age 55
live to 85
401K=$600000
earn 7% a year but want to take 4% out so the base amount doesn't run out and I can see what I could leave to my kids?

I like this simulator. https://ficalc.app/

Excel. I built one a few years back for someone. I will see if I can find it.
Don't forget to tax the 401k withdraw as income and grow your expenses at inflation (or more). Any AI agent can do it pretty quick as well.

This. You can plug in as many scenarios as you like with as many variables as you can think of. AI will give you output in any format.

It can also create a spreadsheet to do it for you. The following took it about 5 - 10 minutes simply based on a screenshot of the OP.

Thank you guys. Im not good at AI or anything tech. But in the example I could withdraw $24K a year? and my account would stay the same or still grow? If so that is good news.

Forget what I said earlier. Do what @Exhausted did. Ask it to create a Monte Carlo simulation as well. Powerful stuff created in minutes! This may just help my mental health as well.

I would consider 4% overly conservative, look into dynamic withdrawal strategies. Plenty of youtube stuff out there.
Even the guy who came up with the 4% rule has come out and said that it was only for the worst scenario in the last 130 years, most could safely withdrawal close to 5%.

That is the number I would definitely inflation adjust. you expenses are not going to stay the same for 30 years. This is why it helps to do it yourself. Play with the numbers and think through the result. The real problem is that the return assumption isn't static while model thinks it is. You need to be able to weather a 20% decline for a couple of years.

What’s the right percentage? I knew 4% was conservative but is 5% still low? In a perfect world, I should be able to withdraw funds and have slight growth in the accounts over a long term, recognizing recession in the overall long term return.

If you retired today you could invest the entire amount in a 30 yr Treasury that would pay you a 5% coupon and at the end of the 30yrs you get the principal back. Again, the problem is that $30k today will not equal $30k in 20-30yrs and at the end of the term the principal certainly won't have the same spending power.

My crystal ball is just as cloudy as yours. Only certainty besides death and taxes is uncertainty.
I'm planning 5.5-6% withdrawal to start using guardrail withdrawal strategy, that with 3-5 years of spending in high yield savings and treasuries should allow for market swings.
I'm fortunate to have a pretty big retirement base income with the wife's and my pensions and pretty good SS earnings history. Everyone's situation will vary.
The 4% inflation adjusted for 30 years usually doesn't hold up for the life of a retirement. You can look into spending smile research that's out there. The goal for most shouldn't be to die with the biggest account balance, IMHO. I spent 40 years saving it and accruing, I sure plan on enjoying as much of it as I can spend safely.

I've been pulling around 4% out of mine for 7-8 years now as well as two lumps sum withdrawals ($50k & $100K) and due to market performance we have considerably more than what we started with. Just about to turn 67, might bump up to 6% or so in the not too distant future.

The big "what ifs" are the inflation rate and market performance. Since nobody has a crystal ball past history is all we have to go on.

The fact that you are even thinking about this puts you miles ahead of the average American. You're probably going to be okay.
