A new analysis estimated that President Donald Trump racked up a $103 billion bill for the Iran war in 120 days.

According to an analysis by Popular Information, the Trump administration has no plan to pay for the Iran war, and neither do congressional Republicans.

The analysis found that over four months, the U.S. spent more than $103 billion on the war in Iran, based on budgetary costs such as operations, personnel, and matériel. It also noted that Russell Vought, the director of the Office of Management and Budget, told the House Appropriations Committee last week that the U.S. has spent $30 billion on the war.

According to Popular Information, expenses for weapons such as missiles, interceptors, and bombs total about $46.7 billion, making it the highest cost. The other major expenses included operations such as mobilization, administration, and combat, which cost $28.5 billion, and losses such as damage or destruction of military assets, which cost $20.3 billion, per the analysis.

"The Trump administration has offered Congress lowball war cost estimates," Popular Information noted. In May, Pentagon comptroller Jay Hurst and Defense Secretary Pete Hegseth testified that the war cost only $29 billion. In April, the estimate was $25 billion.

The Trump administration and congressional Republicans are declining to pay for the war costs through tax increases or spending cuts, according to Popular Information, which included a quote from House Appropriations Chair Tom Cole (R-OK) saying, "War is never paid for when you fight it."

However, taxes were levied to pay for the costs of World Wars I and II, Popular Information noted.
