Supergirl may not need Superman numbers to be considered a win, but it still has a clear box office target to hit.
According to Puck News‘ Scott Mendelson, the upcoming DCU movie is estimated to need around $425 million worldwide to be viewed as “good enough” at the box office.
The report says the budget for Supergirl is unavailable, but estimates it at roughly $170 million.
For comparison, Puck notes the number would put the Craig Gillespie-directed movie closer to Jon Favreauâs The Mandalorian and Grogu, which reportedly cost $165 million, than James Gunnâs Superman, which reportedly cost $225 million (we’ve been told more).
The new report follows the growing scrutiny around the Supergirl PR campaign, which has already raised questions about how Warner Bros. is selling the next DCU movie.

Supergirl Can Make Less Than Superman And Still Win
Puck argues Supergirl can gross less than Superman and still be spun as a win for DC Studios and Warner Bros.
Superman, starring David Corenswet, finished with $354 million domestic and $618.7 million worldwide. Since Supergirl is reportedly coming in with a lower budget, the movie would not need to match Supermanâs global total to be considered successful.
Puck says Warner Bros. would surely prefer Supergirl to clear $500 million worldwide. However, the report adds good reviews, good legs, and a global gross around $425 million may be âgood enough.â
A lot will depend on the response from critics and fans.
Milly Alcock made her DCU debut as Kara in Superman, where the movie briefly introduced the Woman of Tomorrow before her solo film. Puck notes audiences seemed âat least somewhat curiousâ about Alcockâs version of the character, which could help build interest in Supergirl.

DC Needs Supergirl To Keep The Momentum Going
Supergirl is not just another DC movie. It is the second theatrical installment in James Gunn and Peter Safranâs new DCU.
Superman gave DC Studios a starting point, but Variety recently reported it was not viewed as a complete home run. The movie made over $600 million worldwide, which is solid, but not in the range of the biggest superhero wins from past years.
Now Supergirl has to prove the new DCU can expand beyond Superman.
The movie also arrives at a difficult time for the superhero genre. Marvel has struggled to maintain its old dominance, and DC is still trying to rebuild trust with fans after years of reboots, cancellations, and mixed results.
Puck also points to Warner Bros.â weaker first half of 2026. The studioâs current year has not matched the same period from last year, which included Minecraft, Sinners, and Final Destination Bloodlines.
So while $425 million may be enough on paper, Warner Bros. likely wants more than âgood enough.â

Break-even is “good enough” for Supergirl?
Whatâs interesting is how Puck frames the $425 million figure.
The outlet notes industry executives typically look for about 2.5x the production budget when measuring return on investment. That number is usually used as a rough way to tell if a movie broke even, not if it made a big profit.
So if Supergirlâs budget is around $170 million, the $425 million target suggests Puck is saying Warner Bros. could view the movie as a success if it reaches the break-even number (it’s better than losing money).
Puck also notes Warner Bros. would likely prefer a $500 million-plus global gross, which makes sense. That would move Supergirl beyond the break-even number and into a cleaner profit story for the studio.

Supergirl Faces Fan And Box Office Pressure
The $425 million target arrives as Supergirl is already under the microscope.
The early PR push has drawn backlash from fans, with some taking issue with how the movie is being positioned and promoted. For Warner Bros., the challenge is selling Supergirl as its own movie while also keeping the larger DCU momentum alive.
Puck describes the movie as an outer-space superhero flick âby way of John Wick,â which could give Supergirl a different flavor from Superman.
A lower box office target helps reduce the pressure, but it does not remove it. If Supergirl lands in the $425 million range with strong reviews and fan support, Warner Bros. can call it a win (again, better than losing money).
If it comes in soft or gets rejected by the audience, James Gunn and the DCU will face new questions fast.
Supergirl opens June 26th.
