| Expenses Paid, Amount | $ 71 |
| Expense Ratio, Percent | 0.69% |
| Factors Affecting Performance [Text Block] | Management's discussion of fund performance The fund’s Class A shares gained 5.71% for the year ended November 30, 2024. That result compares with a 6.26% gain for the Bloomberg U.S. Treasury Inflation-Protected Securities (TIPS) 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 During the fund’s fiscal year, the U.S. bond market experienced increased volatility. Yields rose through late April, followed by a decline. This was due in part to easing inflation and expected U.S. Federal Reserve (Fed) interest rate cuts in response to softening labor market conditions. Yields rose again in mid-September in anticipation of stronger economic growth and the possibility that total U.S. debt would increase in 2025. Interest rate positioning was the key driver of relative returns over the fund’s fiscal year, with active duration positioning making a positive contribution. Entering 2024 with an underweight to duration helped returns as rates rose due to stronger-than-expected economic data and a reassessment of the Fed’s monetary policy path. As economic data showed signs of softening, the fund’s managers moved to a longer duration position, allowing the portfolio to benefit from falling rates. From a sector positioning perspective, modest positive contributions came from small out-of-benchmark exposures to securitized credit, municipal bonds and emerging markets debt. Conversely, the fund’s hedging of credit risk had a negative impact in an environment in which credit outpaced most fixed income sectors, including both nominal and inflation-linked Treasuries. Positioning for a steeper yield curve also detracted from the fund’s results. * * |

| Factors Affecting Performance [Text Block] | Management's discussion of fund performance The fund’s Class 529-A shares gained 5.63% for the year ended November 30, 2024. That result compares with a 6.26% gain for the Bloomberg U.S. Treasury Inflation-Protected Securities (TIPS) Index. For information on returns for additional periods, including the fund lifetime, please refer to capitalgroup.com/mutual-fund-returns-529A What factors influenced results During the fund’s fiscal year, the U.S. bond market experienced increased volatility. Yields rose through late April, followed by a decline. This was due in part to easing inflation and expected U.S. Federal Reserve (Fed) interest rate cuts in response to softening labor market conditions. Yields rose again in mid-September in anticipation of stronger economic growth and the possibility that total U.S. debt would increase in 2025. Interest rate positioning was the key driver of relative returns over the fund’s fiscal year, with active duration positioning making a positive contribution. Entering 2024 with an underweight to duration helped returns as rates rose due to stronger-than-expected economic data and a reassessment of the Fed’s monetary policy path. As economic data showed signs of softening, the fund’s managers moved to a longer duration position, allowing the portfolio to benefit from falling rates. From a sector positioning perspective, modest positive contributions came from small out-of-benchmark exposures to securitized credit, municipal bonds and emerging markets debt. Conversely, the fund’s hedging of credit risk had a negative impact in an environment in which credit outpaced most fixed income sectors, including both nominal and inflation-linked Treasuries. Positioning for a steeper yield curve also detracted from the fund’s results. * * |

| Factors Affecting Performance [Text Block] | Management's discussion of fund performance The fund’s Class 529-F-3 shares gained 6.16% for the year ended November 30, 2024. That result compares with a 6.26% gain for the Bloomberg U.S. Treasury Inflation-Protected Securities (TIPS) Index. For information on returns for additional periods, including the fund lifetime, please refer to capitalgroup.com/mutual-fund-returns-529F3 What factors influenced results During the fund’s fiscal year, the U.S. bond market experienced increased volatility. Yields rose through late April, followed by a decline. This was due in part to easing inflation and expected U.S. Federal Reserve (Fed) interest rate cuts in response to softening labor market conditions. Yields rose again in mid-September in anticipation of stronger economic growth and the possibility that total U.S. debt would increase in 2025. Interest rate positioning was the key driver of relative returns over the fund’s fiscal year, with active duration positioning making a positive contribution. Entering 2024 with an underweight to duration helped returns as rates rose due to stronger-than-expected economic data and a reassessment of the Fed’s monetary policy path. As economic data showed signs of softening, the fund’s managers moved to a longer duration position, allowing the portfolio to benefit from falling rates. From a sector positioning perspective, modest positive contributions came from small out-of-benchmark exposures to securitized credit, municipal bonds and emerging markets debt. Conversely, the fund’s hedging of credit risk had a negative impact in an environment in which credit outpaced most fixed income sectors, including both nominal and inflation-linked Treasuries. Positioning for a steeper yield curve also detracted from the fund’s results. * * |

| Factors Affecting Performance [Text Block] | Management's discussion of fund performance The fund’s Class R-5E shares gained 5.93% for the year ended November 30, 2024. That result capitalgroup.com/mutual-fund-returns-R5E What factors influenced results During the fund’s fiscal year, the U.S. bond market experienced increased volatility. Yields rose through late April, followed by a decline. This was due in part to easing inflation and expected U.S. Federal Reserve (Fed) interest rate cuts in response to softening labor market conditions. Yields rose again in mid-September in anticipation of stronger economic growth and the possibility that total U.S. debt would increase in 2025. Interest rate positioning was the key driver of relative returns over the fund’s fiscal year, with active duration positioning making a positive contribution. Entering 2024 with an underweight to duration helped returns as rates rose due to stronger-than-expected economic data and a reassessment of the Fed’s monetary policy path. As economic data showed signs of softening, the fund’s managers moved to a longer duration position, allowing the portfolio to benefit from falling rates. From a sector positioning perspective, modest positive contributions came from small out-of-benchmark exposures to securitized credit, municipal bonds and emerging markets debt. Conversely, the fund’s hedging of credit risk had a negative impact in an environment in which credit outpaced most fixed income sectors, including both nominal and inflation-linked Treasuries. Positioning for a steeper yield curve also detracted from the fund’s results. * * |
