| Objective [Heading] | rr_ObjectiveHeading | Goal | |||||||||
| Objective, Primary [Text Block] | rr_ObjectivePrimaryTextBlock | Putnam U.S. Government Income Trust seeks as high a level of current income as Putnam Investment Management, LLC believes is consistent with preservation of capital. | |||||||||
| Expense [Heading] | rr_ExpenseHeading | Fees and expenses | |||||||||
| Expense Narrative [Text Block] | rr_ExpenseNarrativeTextBlock | The following table describes the fees and expenses you may pay if you buy and hold shares of the fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $100,000 in class A shares or $50,000 in class M shares of Putnam funds. More information about these and other discounts is available from your financial advisor and in How do I buy fund shares? beginning on page 12 of the fund’s prospectus and in How to buy shares beginning on page II-1 of the fund’s statement of additional information (SAI). | |||||||||
| Shareholder Fees Caption [Text] | rr_ShareholderFeesCaption | Shareholder fees (fees paid directly from your investment) | |||||||||
| Operating Expenses Caption [Text] | rr_OperatingExpensesCaption | Annual fund operating expenses (expenses you pay each year as a percentage of the value of your investment) |

| Portfolio Turnover [Heading] | rr_PortfolioTurnoverHeading | Portfolio turnover | |||||||||
| Portfolio Turnover [Text Block] | rr_PortfolioTurnoverTextBlock | The fund pays transaction-related costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher turnover rate may indicate higher transaction costs and may result in higher taxes when the fund’s shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or the above example, affect fund performance. The fund’s turnover rate in the most recent fiscal year was 512%. | |||||||||

| Expense Breakpoint Discounts [Text] | rr_ExpenseBreakpointDiscounts | You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $100,000 in class A shares or $50,000 in class M shares of Putnam funds. More information about these and other discounts is available from your financial advisor and in How do I buy fund shares? beginning on page 12 of the fund's prospectus and in How to buy shares beginning on page II-1 of the fund's statement of additional information (SAI). | |||||||||

| Expense Example [Heading] | rr_ExpenseExampleHeading | Example | |||||||||
| Expense Example Narrative [Text Block] | rr_ExpenseExampleNarrativeTextBlock | The following hypothetical example is intended to help you compare the cost of investing in the fund with the cost of investing in other funds. It assumes that you invest $10,000 in the fund for the time periods indicated and then, except as indicated, redeem all your shares at the end of those periods. It assumes a 5% return on your investment each year and that the fund’s operating expenses remain the same. Your actual costs may be higher or lower. | |||||||||
| Strategy [Heading] | rr_StrategyHeading | Investments | |||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | We invest mainly in bonds and securitized debt instruments (such as mortgage-backed investments) that are obligations of the U.S. government, its agencies and instrumentalities and accordingly are backed by the full faith and credit of the United States (e.g., U.S. Treasury bonds and Ginnie Mae mortgage-backed bonds) or by only the credit of a federal agency or government-sponsored entity (e.g., Fannie Mae and Freddie Mac mortgage-backed bonds), and that have short- to long-term maturities. We may consider, among other factors, credit, interest rate and prepayment risks, as well as general market conditions, when deciding whether to buy or sell investments. We typically use to a significant extent derivatives, such as futures, options, and swap contracts, for both hedging and non-hedging purposes. | |||||||||
| Risk [Heading] | rr_RiskHeading | Risks | |||||||||
| Risk Narrative [Text Block] | rr_RiskNarrativeTextBlock | It is important to understand that you can lose money by investing in the fund. The prices of bonds in the fund’s portfolio may fall or fail to rise over extended periods of time for a variety of reasons, including both general financial market conditions and factors related to a specific issuer or industry. The risks associated with bond investments include interest rate risk, which means the prices of the fund’s investments are likely to fall if interest rates rise. Bond investments also are subject to credit risk, which is the risk that the issuers of the fund’s investments may default on payment of interest or principal. Credit risk is generally greater for debt not backed by the full faith and credit of the U.S. government, and interest rate risk is generally greater for longer-term bonds. Mortgage-backed investments carry the risk that they may increase in value less when interest rates decline and decline in value more when interest rates rise. We may have to invest the proceeds from prepaid investments, including mortgage- and asset-backed investments, in other investments with less attractive terms and yields. Our use of derivatives may increase these risks by increasing investment exposure (which may be considered leverage) or, in the case of many over-the-counter instruments, because of the potential inability to terminate or sell derivatives positions and the potential failure of the other party to the instrument to meet its obligations. The fund may not achieve its goal, and it is not intended to be a complete investment program. An investment in the fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. |
