So I have another worksheet where I track the actual withdrawals each month and the running average YTD and the necessary amount for the remaining months.

I've actually always wondered this about folks who use more complicated variable-spending rules. So, you basically use that Guyton-Klinger number as an upper-limit to spending, and leave the rest that you don't use in your portfolio? It's not like you see a G-K spending level of $70k, up from $65k the year before and say to yourself "Welp honey, looks like we need to spend some more money!", right?

I guess that I'm not sophisticated enough. I just have a monthly transfer from cash to checking that covers most of our regular living expenses and then transfer additional funds when needed to cover special expenses (vacation, major repair, new car, etc.).

The transfers for a year is what I withdrew and I periodically reassess whether I "have enough" as if I was retiring anew today. If my "have enough" calculations start to creep into a zone of discomfort I would scale back on discretionary expenses, if it goes the other way (as it has since I retired 20 months ago) I allow us an occasional splurge.

I'm in the same boat as pb4uski. I transfer a fixed amount monthly from my cash reserve savings account to checking. I'm only into my 3rd year of doing this and haven't even increased the amount for inflation yet. Somehow, I have managed to accrue a nice balance in checking over the last few years which will cover many extra expenses such as dental work that is not covered on my plan, vacation etc.

The only big extra expenditure I foresee in a few years may be the purchase of a nice, used RV. For that, I'll just take the cash out of the main stash.

Like my old Grand Pappy used to say "Never let the perfect become the enemy of the good." Or to rephrase it for this discussion "Don't let analyzing to the nth degree become the enemy of making some prudent calculations."

+1 from me as well.

However, for those who are of a more analytical mindset, I do enjoy reading the discussions that result. One of the great things about this forum is that the different approaches are rarely promoted with religious fervor; there is an air of genuine scientific interest.

At the very least, if any of us are looking down on others for their approach, we have the decency to keep it to ourselves

I had an old boss that used to say, "A good plan today is better than a great plan tomorrow."

I started out doing it that way when I first retired (7 years ago). It's probably a reasonable way to start off while you are getting used to the whole "no paycheck" thing.

But it soon becomes apparent that it's nothing but mental accounting. "Move money to a savings account that I pretend is part of my portfolio, then once a month move money from the savings account to the checking account. And when/if we don't spend it all by the end of the month, move the excess back to the savings account and make a note that we can take it back when/if a month comes when we need a little extra. Oh, and also mentally note than some of the money in the savings account is earmarked for new car/roof/furnace, etc."

Or do you move the excess to a different savings account so you don't get the money mixed up? And do you also have another savings account for the money you'll need for infrequent special expenses? Suddenly you've got half a dozen savings/checking accounts, each one earmarked for a different category of spending.

And then you realize the absurdity of it all. All you are doing is moving money from one savings account to another one. What's the point of that?

It seemed simpler to me to approach it from the opposite direction. Instead of funneling out a specific amount money and then directing it to different usages, keep running track of the expenditures and generally keep it down to the amount that your SWR calculation says.

Normal method, similar to what you do when your income is a paycheck, is get a constant monthly income and parcel it out to expenses.
My method is to pay expenses and vary the monthly income, under the constraint that the annual income cannot be more the $X.
"Income" = withdrawal from portfolio.

It's just a lot easier. If in Feb you have a large expense (new car, luxury cruise, etc.) you pay it, and cover it by reducing the allowed spending for Mar-Dec. If you didn't spend much from Jan to Jul, you can splurge in Aug (or small splurge in Aug-Dec) because the money you didn't take is still there.
The target is to end in December with the average monthly withdrawal for the last 12 months to be equal to the amount that your SWR says.

It's easy to set up in a spreadsheet. You only have to keep track of one thing -- the money you transfer to your checking account and then spend. Computing the running average since BOY and the to-go-to-EOY average is simple.

My method is even easier, I use SWR as a guideline, if I go over SWR because of a big ticket item, no worries. I just check my withdrawals at the end of the year to see how much I spent. No spreadsheet of expenses, no trying to cut expenses for the rest of the year...hey this is retirement, it's suppose to be fun , tracking my expenses with spreadsheets and forcing myself to stay under some arbitrary limit, that's no fun (Note if the economy tanks again, I would just postpone any big ticket item.)

That is also our plan, to follow a VWR approach using Guyton-Klinger rules to guide withdrawals, as discussed in this thread. http://www.early-retirement.org/foru...ml#post1373036

Using a 'floor & ceiling or 'guardrails' approach like the 'Guyton-Klinger' enables higher beginning WDR. It also has the possibility of a lower WDR but, provides the structure for making adjustments as time and circumstances occur, with some knowledge of where it all ends up. I like this combo of discipline and flexibility.

For example, with our AA, we forecast surviving a 40 yr period and could begin with a 5.3% 'real' WDR (we plan to start with 5.0%), which has a worst case possibility of reducing to a 'real' 3.7% WDR over an eight year period but, also has the possibility of increasing to a WDR >5.3%.

3.7/5.0=76% So, 24% is a large % decrease in annual income, if the worst case comes to pass. However, in our situation, we have some pension income that comes on-line about two years into FIRE, which would temper that reduction. So, G-K seems to be a good fit for our situation. Benefits of the approach include:

1. Higher starting WDR earlier in RE when it's most useful.
2. An approach that is flexible to accommodate bad sh!t happening
3. An approach that provides a disciplined structure, which I think we need.

Rayvt-I'd be interested in hearing how G-K has worked for you thus far.

Just read this thread from start to finish. Interesting. Our financial affairs seem pretty simple compared to some here. We just spend our pensions and dividends. Keep a fairly large cash balance to absorb lumpy expenses like new cars or expensive trips. Vitually all portfolio is in taxable accounts. Tax planning pretty simple as we pay at the max marg rates and always will. If I was in the same position as some of you, I think I would spend a lot of time analyzing taxes as well.
I am probably leaving some money on the table as I manage all our financial affaires myself but I like doing it and this keeps if simple and understandable.
