I have a question mostly for the folks who have been ERd for a few years or more and calculate their withdrawal rates. I know to calculate the WR for a year, you basically divide your withdrawals during the year by your beginning balance. But do you just calculate it once a year, every quarter, or every month? I have been calculating it each month, and the numbers fluctuate too much to be meaningful - a longer time period would smooth it out somewhat. Basically, I'm thinking that after I have several years of data, I can calculate a "composite" WR since ER, but what is formula to do this?. I guess the best way to do this is to take the WR for each year and average it. I could also add up all the withdrawals and divide by the original portfolio value, but the values goes up each month and don't want to keep dividing by a number that may be years old. I love playing around with numbers and maybe I'm looking at the details instead of the big picture. Just curious how often folks calculate their WR .
