Pay vs Performance Disclosure [Table] |  |  |
Pay vs Performance [Table Text Block] | 2022 Pay Versus Performance Table The table below shows the following information for the past three fiscal years: (i) “total” compensation for our NEOs for purposes of the “Summary Compensation Table” and shown on an average basis for the non-CEO NEOs; (ii) the “Compensation Actually Paid” (or CAP) to our NEOs (calculated using rules required by the SEC) and shown on an average basis for the non-CEO NEOs; (iii) our total shareholder return (TSR); (iv) the TSR of our peer group; (v) our GAAP Net Income; and (vi) our Core EPS. CAP does not represent the value of cash and shares of the company’s common stock received by the NEOs during the applicable year, but rather is an amount calculated under SEC rules and includes, among other things, year-over-year changes in the value of unvested equity-based awards. As a result of the calculation methodology required by the SEC, the CAP amounts in the table below differ from compensation actually received by the NEOs and the compensation decisions described in the “ Compensation Discussion and Analysis ” discussion in this Proxy Statement.

Compensation Actually Paid vs. Total Shareholder Return [Text Block] | CAP vs. CBRE ’ s TSR. Over the 2020-2022 period, our CEO and other NEOs’ CAP amounts are higher than Summary Compensation Table total compensation amounts in years when the company’s TSR is positive, and lower than Summary Compensation Table total compensation amounts in years when the company’s TSR is negative. This alignment is because the majority of our NEOs’ executive compensation (excluding strategic equity awards) is in the form of equity (79% for our CEO and 61%, on average, for our other NEOs). |  |
Compensation Actually Paid vs. Net Income [Text Block] | CAP vs. CBRE’s GAAP Net Income. While our GAAP Net Income has increased and decreased directionally with CAP amounts over the 2020-2022 period, the changes in GAAP Net Income are not proportionally correlated to CAP. The lack of correlation is primarily because CAP values for a given year are strongly influenced by year-over-year changes in our TSR, which do not always correlate to annual GAAP Net Income. In addition, GAAP Net Income is not a measure used in our incentive plans. |  |
Compensation Actually Paid vs. Company Selected Measure [Text Block] | CAP vs. CBRE’s Core EPS. Our Core EPS increased each year from 2020 to 2022. However, CAP amounts fluctuated over the same time period, with lower CAP values in 2020 and 2022, and higher CAP values in 2021. The lack of correlation is partly because CAP values for a given year are strongly influenced by year-over-year changes in our TSR, which do not always correlate to annual Core EPS. Also, in our annual performance-based RSU program, Core EPS is measured cumulatively over a two-year period against internally-established goals. Because of the different measurement periods ( i.e. , year-over-year change for CAP vs. two-year cumulative measurement for Core EPS in our annual performance-based RSU program), as well as the fact that the Core EPS goals are set versus in ter nal budgets and not based on a fixed year-over-year growth rate, there is no correlation between Core EPS and CAP values for the three-year period. |  |
Total Shareholder Return Vs Peer Group [Text Block] | CBRE’s TSR vs. Peer Group TSR . The company’s indexed TSR outperformed the Peer Group indexed TSR in each year of the three-year period measured. |  |
Tabular List [Table Text Block] | The most important financial performance measures that we use to link executive compensation actually paid to the NEOs for the most recently completed fiscal year to our performance are as follows:
• |  | Core Earnings per share, or Core EPS
• |  | Core EBITDA
• |  | Segment Operating Profit
• |  | Relative TSR
• |  | Relative Adjusted EPS Growth
Core EPS was selected as the company-selected measure for the Pay ve rsus Performance table below because it has the strongest alignment with long-term shareholder value. Core EPS is used to det ermi ne the number of shares earned in our performance-based RSU program, which comprises a significant portion of our NEOs’ target pay opportunities. |  |
