Contract extensions have been one of the biggest storylines for the 49ers this offseason. And that’s carried right into the regular season as well. They couldn’t lock down a long-term deal with wideout Jauan Jennings, no doubt about it. But they undoubtedly took care of another key piece. This time, it was their right tackle, Colton McKivitz. The OT was entering the final year of his previous deal.

And just like any other player, McKivitz was engaged in strategic hold-in. The guy attended the team events, sure. But when it came to active participation, he was nowhere to be seen. As the 49ers secured their first win of the season against the Seahawks, we just got an insight that the 29-year-old tackle has signed a three-year, $45 million ($27 million guaranteed) contract extension with the 49ers. That said, let’s have a look at McKivitz’s net worth and career earnings in 2025 after his new deal.

How much is Colton McKivitz’s career earnings?

Heading into the sixth season of his career with the Niners, the 29-year-old has signed multiple contract extensions so far. And if we take a look at his career earnings, let’s just say McKivitz managed to cash in a pretty chunk of money. A former fifth-rounder, the OT signed his rookie deal back in 2020, worth $3.62 million ($329K signing bonus).

However, he had to endure waivers, re-signing, and even battling a high ankle sprain before he eventually signed his contract extension in 2023. We’re talking about a $4.61 million extension that kept him with the Niners through the 2024 season. McKivitz started for the Niners in Super Bowl LVIII. Unfortunately, the 49ers fell to the Chiefs 25-22 in overtime.

But the OT managed to sign another contract extension in the offseason. This time, a one-year, $5.85 million deal. Fast forward to now, like many other Niners players, McKivitz was expected to get a contract extension. And considering the guy started every game in the last couple of seasons and pressured the front office for a new deal, the Niners finally agreed to a three-year deal.

If we round all that up, Spotrac projects that Colton McKivitz has an estimated career earnings of .$10.27 million so far. As for his net worth in 2025?

How much is the Niners’ OT’s net worth in 2025?

Including his career earnings across five seasons, McKivitz has an estimated net worth of $9 million. While it’s still not clear whether McKivitz has any endorsement deals, one thing’s clear: with his new three-year deal, the OT is now positioned to earn a significant chunk of money for many more years to come, considering the Niners have locked McKivitz through the 2028 season.

And that means only one thing: the 29-year-old will continue to be a key player on the 49ers’ offensive line, protecting the quarterback, Brock Purdy—who also signed an extension this offseason—for several more years. The 49ers have already pulled off a 17-13 win over the Seahawks, and next up, they’ll take on the Saints on September 14.
