Due to the fact that Shanks bounty is unknown, and we haven't seen any serious fights that actually went down, we can only estimate Shanks power from his brief appearances, and the dialogues about him:

1. He lost his arm to a Sea King in an attempt to save Luffy, then uses Conquerors Kaki(Haoshoku Haki) to scare it off.
2. He uses Conquerors Haki to knock out most of Whitebeards crew, then briefly clashes blades with Whitebeard, the strongest man in the world.
3. He stops Akainu with his sword and saved Koby.
4. When he had two arms, he was in contention with Mihawk as the strongest swordsman in the world. Whitebeard himself said that he still remembers the fights between Mihawk and Shanks, and they echoed all around the Grand Line. However, Mihawk is no longer interested in fighting him.
5. In Chapter 907, he went into Mary Geoise to talk with the five elders.

Based on this information, I would say that Shanks is well deserved of his title as Yonko, but not as powerful as the other three. He could also probably take on a Marine Admiral or even the fleet admiral individually. Given that the Navy suffered massive losses already at the battle, I would say that Shanks, along with his crew, is powerful enough of a threat, to stop the war at that point.

Since a bounty has not been released, and we haven't seen any actual fighting (except three brief occasions, and those were VERY brief), we can only estimate the power of Shanks from his brief appearances, and dialogue about him:

1. He gets his arm bit off by a Sea King to save Luffy, then uses Haoshoku Haki to scare him off.
2. He uses Haoshoku Haki to knock out most of his crew, then briefly clashes blades with Whitebeard, the strongest man in the world.
3. He stops Akainu with his sword and saved Koby.
4. When he had two arms, he was in contention with Mihawk as the strongest swordsman in the world. Whitebeard himself said that he still remembers the fights between Mihawk and Shanks, and they echoed all around the Grand Line. However, Mihawk is no longer interested in fighting him.
5. In Chapter 907, he snuck into Mary Genoise to talk with the five elders.

He could also probably take on a Marine Admiral or even the fleet admiral individually.
