According to Celebrity Net Worth, Katie McGrath has a net worth of $4 million. Her wealth is believed to be accumulated mostly from her acting career and endorsements (via All Star Bio). Like many stars nowadays, the "Merlin" star keeps her life pretty low-key from the public. Not much is known about where she spends her wealth, since she has no known social media. However, a couple things known about her are that she currently lives in Ashford, Wicklow, Ireland, and that she appears to not drive any car (via CelebsMoney).
McGrath is keeping it low-key in the acting world as well. Her only role in 2021 so far has been to reprise her role as Lena Luthor in the final season of "Supergirl," alongside Melissa Benoist (via IMDb). Fans are super excited to see what will happen next for the raven-haired beauty!
