|
| Allspring Variable Trust - Class 2 | VT Index Asset Allocation Fund | Debt Securities Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Debt Securities Risk. Debt securities are subject to credit risk and interest rate risk. Credit risk is the possibility that the issuer or guarantor of a debt security may be unable, or perceived to be unable or unwilling, to pay interest or repay principal when they become due. In these instances, the value of an investment could decline and the Fund could lose money. Credit risk increases as an issuer’s credit quality or financial strength declines. Interest rate risk is the possibility that interest rates will change over time. When interest rates rise, the value of debt securities tends to fall. The longer the terms of the debt securities held by a Fund, the more the Fund is subject to this risk. If interest rates decline, interest that the Fund is able to earn on its investments in debt securities may also decline, which could cause the Fund to reduce the dividends it pays to shareholders, but the value of those securities may increase. Very low or negative interest rates may magnify interest rate risk.
|
| Allspring Variable Trust - Class 2 | VT Index Asset Allocation Fund | Derivatives Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Risk. The use of derivatives, such as futures, options and swap agreements, can lead to losses, including those magnified by leverage, particularly when derivatives are used to enhance return rather than mitigate risk. Certain derivative instruments may be difficult to sell when the portfolio manager believes it would be appropriate to do so, or the other party to a derivative contract may be unwilling or unable to fulfill its contractual obligations.
|
| Allspring Variable Trust - Class 2 | VT Index Asset Allocation Fund | Futures Contracts Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Futures Contracts Risk. A Fund that uses futures contracts, which are a type of derivative, is subject to the risk of loss caused by unanticipated market movements. In addition, there may at times be an imperfect correlation between the movement in the prices of futures contracts and the value of their underlying instruments or indexes, and there may at times not be a liquid secondary market for certain futures contracts.
|
| Allspring Variable Trust - Class 2 | VT Index Asset Allocation Fund | Index Tracking Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Index Tracking Risk. A Fund may not achieve exact correlation between the performance of the Fund and the index it tracks due to factors such as transaction costs, shareholder purchases and redemptions and the timing of changes in the composition of the index. The Fund may invest in only a representative sample of the securities that comprise the index and may hold securities not included in the index, subjecting the Fund to increased tracking risk. Maintaining investments in securities regardless of market conditions or the investment merits of the securities in seeking to replicate an index’s composition or performance could cause the Fund’s returns to be lower than if the Fund employed an active strategy.
|
| Allspring Variable Trust - Class 2 | VT Index Asset Allocation Fund | U.S. Government Obligations Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government. U.S. Government obligations may be adversely affected by a default by, or decline in the credit quality, of the U.S. Government.
