| Factors Affecting Performance [Text Block] | Management's discussion of fund performance The fund’s Class A shares gained 17.49% for the year ended October 31, 2024. That result compares with a 16.54% gain for the S&P Target Date Retirement Income Index. For information on returns for additional periods, including the fund lifetime, please refer to capitalgroup.com/mutual-fund-returns-A What factors influenced results Equity markets climbed as the U.S. economy appeared to avoid a downturn and inflation eased. U.S. equities led, though international equity also posted strong gains. U.S. bond markets rallied as the U.S. Federal Reserve cut interest rates in September for the first time since 2020. Significant exposure to equity-income funds helped on an absolute basis. Core bond exposure was a large absolute fixed-income contributor. Global exposure among balanced funds contributed less than the U.S. as international equities lagged. In fixed income, exposure to intermediate bonds contributed less than other areas of fixed income. |

| Factors Affecting Performance [Text Block] | Management's discussion of fund performance The fund’s Class R-2 shares gained 16.66% for the year ended October 31, 2024. That result compares with a 16.54% gain for the S&P Target Date Retirement Income Index. For information on returns for additional periods, including the fund lifetime, please refer to capitalgroup.com/mutual-fund-returns-R2 What factors influenced results Equity markets climbed as the U.S. economy appeared to avoid a downturn and inflation eased. U.S. equities led, though international equity also posted strong gains. U.S. bond markets rallied as the U.S. Federal Reserve cut interest rates in September for the first time since 2020. Significant exposure to equity-income funds helped on an absolute basis. Core bond exposure was a large absolute fixed-income contributor. Global exposure among balanced funds contributed less than the U.S. as international equities lagged. In fixed income, exposure to intermediate bonds contributed less than other areas of fixed income. |

| Factors Affecting Performance [Text Block] | Management's discussion of fund performance The fund’s Class R-6 shares gained 17.89% for the year ended October 31, 2024. That result compares with a 16.54% gain for the S&P Target Date Retirement Income Index. For information on returns for additional periods, including the fund lifetime, please refer to capitalgroup.com/mutual-fund-returns-R6 What factors influenced results Equity markets climbed as the U.S. economy appeared to avoid a downturn and inflation eased. U.S. equities led, though international equity also posted strong gains. U.S. bond markets rallied as the U.S. Federal Reserve cut interest rates in September for the first time since 2020. Significant exposure to equity-income funds helped on an absolute basis. Core bond exposure was a large absolute fixed-income contributor. Global exposure among balanced funds contributed less than the U.S. as international equities lagged. In fixed income, exposure to intermediate bonds contributed less than other areas of fixed income. |

| Factors Affecting Performance [Text Block] | Management's discussion of fund performance The fund’s Class R-1 shares gained 20.05% for the year ended October 31, 2024. That result compares with a 16.54% gain for the S&P Target Date Retirement Income Index. For information on returns for additional periods, including the fund lifetime, please refer to capitalgroup.com/mutual-fund-returns-R1 What factors influenced results Equity markets climbed as the U.S. economy appeared to avoid a downturn and inflation eased. U.S. equities led, though international equity also posted strong gains. U.S. bond markets rallied as the U.S. Federal Reserve cut interest rates in September for the first time since 2020. Significant exposure to equity-income funds helped on an absolute basis. High-income bonds via multi-sector exposure were the largest absolute fixed-income contributor, driven by robust gains for high-yield bonds. Global exposure among balanced funds contributed less than the U.S. as international equities lagged. In fixed income, inflation-linked bond exposure contributed less than other areas of fixed income as inflation cooled. |

| Factors Affecting Performance [Text Block] | Management's discussion of fund performance The fund’s Class R-5 shares gained 21.23% for the year ended October 31, 2024. That result compares with a 16.54% gain for the S&P Target Date Retirement Income Index. For information on returns for additional periods, including the fund lifetime, please refer to capitalgroup.com/mutual-fund-returns-R5 What factors influenced results Equity markets climbed as the U.S. economy appeared to avoid a downturn and inflation eased. U.S. equities led, though international equity also posted strong gains. U.S. bond markets rallied as the U.S. Federal Reserve cut interest rates in September for the first time since 2020. Significant exposure to equity-income funds helped on an absolute basis. High-income bonds via multi-sector exposure were the largest absolute fixed-income contributor, driven by robust gains for high-yield bonds. Global exposure among balanced funds contributed less than the U.S. as international equities lagged. In fixed income, inflation-linked bond exposure contributed less than other areas of fixed income as inflation cooled. |

| Factors Affecting Performance [Text Block] | Management's discussion of fund performance The fund’s Class F-3 shares gained 24.56% for the year ended October 31, 2024. That result compares with a 16.54% gain for the S&P Target Date Retirement Income Index. For information on returns for additional periods, including the fund lifetime, please refer to capitalgroup.com/mutual-fund-returns-F3 What factors influenced results Equity markets climbed as the U.S. economy appeared to avoid a downturn and inflation eased. U.S. equities led, though international stocks also posted strong gains. U.S. bond markets rallied as the U.S. Federal Reserve cut interest rates in September for the first time since 2020. Significant exposure to equity-income funds helped on an absolute basis. High-income bond funds were strong absolute fixed-income contributors, given robust gains for high-yield bonds. Global exposure among balanced funds contributed less than the U.S. as international equities lagged. In fixed income, inflation-linked bond exposure contributed less than in other areas of fixed income as inflation cooled. |

| Factors Affecting Performance [Text Block] | Management's discussion of fund performance The fund’s Class R-5 shares gained 24.53% for the year ended October 31, 2024. That result compares with a 16.54% gain for the S&P Target Date Retirement Income Index. For information on returns for additional periods, including the fund lifetime, please refer to capitalgroup.com/mutual-fund-returns-R5 What factors influenced results Equity markets climbed as the U.S. economy appeared to avoid a downturn and inflation eased. U.S. equities led, though international stocks also posted strong gains. U.S. bond markets rallied as the U.S. Federal Reserve cut interest rates in September for the first time since 2020. Significant exposure to equity-income funds helped on an absolute basis. High-income bond funds were strong absolute fixed-income contributors, given robust gains for high-yield bonds. Global exposure among balanced funds contributed less than the U.S. as international equities lagged. In fixed income, inflation-linked bond exposure contributed less than in other areas of fixed income as inflation cooled. |
