1) Added up and categorized my spending for August.
2) Then, did a new projection of my spending for 2018, including all expected irregular expenses like property tax.
3) Finally, graphed my normalized annual spending for nine years of retirement, 2010-2018, using my projected spending for 2018 and the real number of dollars spend in prior years (not including the spending on buying/selling/moving when I moved to my Dream Home).
Here's what I came up with; see below. 2013,2015,2016, and 2017 included unusually high dental expenses because of dental implants. Worth every cent.
As for 2018, the drop in expenses for this year doesn't include any of those pesky doggone unexpected, irregular expenses that might pop up between now and the end of the year. It only includes the expected ones.
It's probably a little overly optimistic to assume that my teeth will hold up and that the roof won't suddenly need replacing or some such thing between now and the end of the year.
Fun! Honestly I don't know what our forefathers ever DID for fun without Excel. Paper spreadsheets are fun too, but just not quite as pretty IMO.
