Terminator 2 cost about $100 million to make, with some estimates putting it a little lower or higher—roughly $94 million to $102 million depending on the source.

Quick scoop

The most commonly cited figure is $100 million , which made it one of the most expensive films ever at the time.

Why the number varies

The budget was reported differently because production costs kept climbing during filming, and not every source used the same final accounting.

TL;DR

If you want the short version: about $100 million is the best answer.
