Wage and salary disbursements A576RC1 – FRED – St. Louis Fed.
Took me a while to find this. I was trying to find the total annual US payroll. I found it rather quickly a few years ago but now the payroll services are obfuscating the search engines. Plus it appears that I was looking for payroll and should have been looking for disbursements.
But there it is, $6.54T a year.
In the course of my googlings I came across the Personal consumption expenditures for the US and they run $10.37T. Interesting discrepancy between wages and salary and spending.
