The 49ers and tight end George Kittle finalized a new five-year contract on Tuesday.

The full details of the deal have arrived.

Here they are:

1. Signing bonus: $18.145 million ($3 million to be paid by May 9, 2025, $8.145 million to be paid by September 12, 2025, and $7 million to be paid by April 3, 2026).

16. 2029 per-gave active roster bonus: $750,000 total.

The deal pays out $91.4 million over five years, for an annual average at signing on $18.28 million.

The new-money average for the four-year extension is $76.4 million, an average of $19.1 million per year. Removing the $22.4 million compensation package for 2029, the new-money average is $18 million.

The $18 million practical new-money APY puts him behind Cardinals tight end Trey McBride, whose contract doesn't include an inflated final year, as the highest-paid tight end. At $18 million, Kittle remains ahead of all other tight ends.

The first two years ($33 million) and $2 million of the third year are fully guaranteed at signing. He can unlock another $5 million in 2027 guarantees by reaching any one of nine different possible achievements in 2026: (1) participating in the Pro Bowl as a starter or backup, unless medically excused, after qualifying on the initial ballot; (2) earn first-team or second-team All-Pro honors; (3) gaining 1,000 or more receiving yards; (4) catching 10 or more touchdown passes; (5) catching 60 or more passes for 850 or more yards; (6) catching 60 or more passes for five or more touchdowns; (7) scoring five or more touchdown reception and generating 850 or more receiving yards; (8) participating in 75 percent or more of the offensive snaps and the team wins at least one playoff game; or (9) participating in 65 percent or more of the offensive snaps and catching 60 or more passes.

Kittle replaces the remaining year of his existing contract at $15 million with two guaranteed years at $33 million and another $2 million in guarantees for the third year. He has the ability to bump the total guarantee to $40 million.

The 49ers are committed as a practical matter to two years. It becomes a year-to-year arrangement after that.
