That’s the single biggest expense in most budgets. So it would skew any percentage dramatically. Unless you have a mortgage rate below 3% you may consider paying off your mortgage to dramatically increase your monthly cash flow in retirement.

I spend about the same as when I worked but on very different things. Nothing on kids and a lot more on travel and entertainment (ie golf)

Those are the biggest adjustments/decisions you’ll likely face. Good luck and congratulations. You now have permission to spend! Many retirees scrimp and save their entire life to secure a comfortable retirement and then find it too hard to change their money habits and enjoy the fruits of a successful retirement plan.
