I just went through this exercise with my wife, my answer is $CDN30,000 now (exact calculated spending), and an estimated $CDN36,000 by the end of the year which will be the start of my "early" retirement phase, as in the meaning of active retirement, adventure, travel, not in the sense of "early retirement" which was never my goal in the first place. I am 62 and semi-retired since 2016. I kept a couple of very sweet part-time gigs that I love, she is 45 and just lost her job due to the coronavirus. Although I love my gigs, COVID-19 game me the opportunity to rethink some of my priorities, so I will be retiring completely at the end of the summer to pursue other interests. Spending during our pre-retirement life was $2,500 per month for the two of us, including vacation and travel. We own an inner-city condo in a biggish Canadian city and a vacation acreage on an island in the PSW (we are in Canada, so the PSW is what Americans call the PNW), both paid-off. We will eventually decide to sell one of these properties, both, or none. No rush. Our post-retirement monthly budget will increase to $3,000 to take into account extended medical coverage for my wife (I have full medical and dental coverage) and travel insurance for both when we travel. We were very thorough in our budgeting exercise, and realize our spending is on the lower end of the spectrum, but we could not think of anything we missed or any budget line we wanted to increase.
