Bar Chart and Performance Table [Heading] Fund Performance
Performance Narrative [Text Block]
The bar chart and table below provide an indication of risk by showing changes in the Fund’s performance over time. The bar chart shows how the Fund’s performance has varied from year to year. The table shows how the Fund’s average annual total returns compare to a broad-based securities market index, as well as an additional index with characteristics that are similar to those of the Fund, for the periods indicated. Effective May 1, 2024, a new sub-advisor began managing the Fund. Performance through April 30, 2024 reflects the Fund’s performance under the management of its prior sub-advisor.
On February 5, 2016, the Fund acquired all the assets and assumed all the liabilities of the Fund’s predecessor. In connection with that reorganization, the R5 Class shares of the Fund adopted the performance history and financial statements of the Fund’s predecessor. In the bar chart and table below, for the period prior to February 5, 2016, the performance of the Fund’s R5 Class shares is the performance of the Fund’s predecessor. In the table below, for the period prior to February 5, 2016, the performance of the Fund’s A Class, C Class, Y Class, and Investor Class shares also reflects the returns of the Fund’s predecessor. Additionally, for the period prior to April 30, 2018, the performance of the R6 Class shares reflects the returns of the Fund’s predecessor from January 1, 2016 through February 4, 2016 and the performance of the Fund’s R5 Class from February 5, 2016 through April 29, 2018. In each case, the newer share classes would have had similar annual returns to the Fund’s predecessor or R5 Class shares, as applicable, because the shares of each class represent investments in the same portfolio securities. However, the expenses of the Fund’s predecessor or R5 Class shares, as applicable, differ from those of the newer share classes, which would affect performance. To the extent that the Fund’s predecessor or R5 Class shares, as applicable, may have had lower expenses than the newer share classes prior to February 5, 2016, or April 30, 2018, as applicable, the performance of the Fund’s predecessor or R5 Class shares, as applicable, would likely have been higher than the performance the newer share classes would have realized during the same period. The performance of the newer share classes shown in the table has not been adjusted for differences in operating expenses between those share classes and the shares of the Fund’s predecessor or R5 Class, as applicable, but the A Class and C Class shares performance has been adjusted for the impact of the maximum applicable sales charge.
C Class shares automatically convert to A Class shares 8 years after purchase, if the conversion is available through your financial intermediary. In the table below, the performance for C Class shares  reflects the performance as though C Class shares were held for the full 10-year period. You may obtain updated performance information on the Fund’s website at  www.americanbeaconfunds.com. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

Performance Narrative [Text Block]
The bar chart and table below provide an indication of risk by showing changes in the Fund’s performance over time. The bar chart shows how the Fund’s performance has varied from year to year. The table shows how the Fund’s average annual total returns compare to a broad-based securities market index, as well as an additional market index with characteristics that are similar to those of the Fund,  for the periods indicated.
The chart and the table show the performance of the Fund’s Investor Class shares for all periods. C Class shares automatically convert to A Class shares 8 years after purchase, if the conversion is available through your financial intermediary. In the table below, the performance for C Class shares reflects the performance as though C Class shares were held for the full 10-year period.

Bar Chart and Performance Table [Heading] Fund Performance
Performance Narrative [Text Block]
The bar chart and table below provide an indication of risk by showing changes in the Fund’s performance over time. The bar chart shows how the Fund’s performance has varied from year to year. The table shows how the Fund’s average annual total returns compare to a broad-based securities market index, as well as an additional composite index with characteristics that are similar to those of the Fund, and the two indices that comprise the composite index, for the periods indicated.
The chart and the table show the performance of the Fund’s Investor Class shares for all periods. In the table below, for the period prior to April 30, 2019, the performance of the A Class and C Class shares reflects the returns of the Investor Class shares of the Fund. The newer share classes would have had similar annual returns to the Investor Class shares because the shares of each class represent investments in the same portfolio securities. However, as reflected in the “Fees and Expenses of the Fund” section of this Fund Summary, the expenses of the Investor Class shares differ from those of the newer share classes, which would affect performance. To the extent that the Investor Class shares had lower expenses than a newer share class, the performance of the Investor Class shares would likely have been higher than the newer share class would have realized during the same period. The performance of the newer share classes shown in the table has not been adjusted for differences in operating expenses between those share classes and the Investor Class shares, but the A Class and C Class shares performance has been adjusted for the impact of the maximum applicable sales charge.

* Performance for the 5 Years and 10 Years period has been adjusted to align with the Fund’s audited Financial Highlights for the fiscal year ended December 31, 2021, which reflect the correction of an expense accrual. If performance had been calculated based on the net asset value (“NAV”) per share as of December 31, 2021 without the expense accrual adjustment, performance would have been higher.
