Based on Friday's decision, former President Trump and his co-defendants will likely owe $463.9 million based on their initial fine and the prejudgment interest imposed by the court, according to a representative for the New York attorney general.

Trump himself will likely owe $453.5 million, between his $354.86 million fine and $98.6 million in interest.

The amount of interest owed by the defendants is set to increase every day they do not pay the fines.

New York Attorney General Letitia James, whose office brought the civil fraud case against Donald Trump, described the ruling as a "tremendous victory for this state, this nation, and for everyone who believes that we all must play by the same rules -- even former presidents."

“When powerful people cheat to get better loans, it comes at the expense of honest and hardworking people," James said in a statement. "Everyday Americans cannot lie to a bank to get a mortgage to buy a home, and if they did, our government would throw the book at them. There simply cannot be different rules for different people."

The former president is "finally facing accountability for his lying, cheating, and staggering fraud," she said.

In addition to the fines imposed on Donald Trump and his co-defendants, the judge's decision leaves the Trump Organization in a constrained position to continue operating their New York-based businesses.

While Judge Engoron backtracked on his September summary judgment ruling -- vacating the part of his order that canceled their business certificates -- Donald Trump and his sons are temporarily unable to lead their namesake company. Trump faces a three-year ban on serving as the leader of a New York company, and his sons face two-year bans.

An independent monitor will continue to oversee the company's finances for at least three years, and the company needs to install a director of compliance.

Regarding the combined $364 million owed by the defendants, experts who ABC News spoke with believe it is unlikely any of them foot the bill immediately; instead, they can cover the fine with a bond while they appeal.

On Michael Cohen, Donald Trump's former lawyer and self-described "fixer," Judge Engoron wrote in his ruling that he found the star witness to be a credible witness despite having been convicted of perjury.

"His testimony was significantly compromised by his having pleaded guilty to perjury and by some seeming contradictions in what he said at trial," Engoron wrote. "However, carefully parsed, he testified that although Donald Trump did not expressly direct him to reverse engineer financial statements, he ordered him to do so indirectly, in his 'mob voice.'"

Engoron continued that although the "animosity between the witness and the defendant is palpable, providing Cohen with an incentive to lie, the Court found his testimony credible, based on the relaxed manner in which he testified, the general plausibility of his statements, and, most importantly, the way his testimony was corroborated by other trial evidence."

A "less-forgiving factfinder" might have come to a different conclusion and not believed "a single word of a convicted perjurer," Engoron wrote.

"This factfinder does not believe that pleading guilty to perjury means that you can never tell the truth," he continued. "Michael Cohen told the truth."

Cohen, who pleaded guilty in 2018 to lying to Congress about the Russia probe, addressed the passage on social media, writing on X, "Judge Engoron's determination regarding my veracity at the NYAG Trump civil fraud trial. Michael Cohen told the truth!"

Judge Arthur Engoron vehemently denied the defense's request to end the trial following former Trump attorney Michael Cohen's contradictory testimony.

"The government's key witness has fallen flat on his face," Trump attorney Clifford Robert said when requesting the case be dismissed.

"Absolutely denied. This case has evidence, credible or not, all over the place," said Engoron, who disagreed that Cohen was the case's star witness.

"There's enough evidence to fill this courtroom," Engoron said.

During Cohen's redirect examination, state attorney Colleen Faherty attempted to square Cohen's inconsistent answers by asking about his 2019 congressional testimony again. Cohen testified yesterday that he was "tasked by Trump" to inflate Trump's reported net worth, then today said his 2019 testimony, in which he said Trump never directly told him to do so, was correct.

"Donald Trump speaks like a mob boss … he tells you what he wants without specifically telling you," Cohen said in explaining the inconsistent response. "We understood what he wanted."
