He lost his parents early in his life and was poor, but was diligent in his studies and capable in literary matters. There was a clansman of his who had  high status who wished to adopt him so that he could receive the benefit of that high status when seeking to advance in civil service, but Li Huaiyuan declined, believing doing so would be dishonorable.

He later successively served as secretary general at Yang Prefecture (揚州, roughly modern Yangzhou, Jiangsu) and Yi Prefecture (益州, roughly modern Chengdu, Sichuan), eventually serving as the prefect of Tong Prefecture (同州, roughly modern Weinan, Shaanxi). He was said to be a simple and efficient prefect. At some point, he was recalled to the central government to serve as an advisor to the Crown Prince, then as a senior advisor at the examination bureau of government (鸞臺, "Luantai"), then the deputy minister of rites (春官侍郎, "Chunguan Shilang"), and then as "Luantai Shilang" (), the deputy  head of the examination bureau. In 701, during the reign of Wu Zetian, Li Huaiyuan was still serving as "Luantai Shilang", when he was given the designation "Tong Fengge Luantai Pingzhangshi" (), making him a chancellor "de facto". Five months later, he was made the minister of justice (秋官尚書, "Qiuguan Shangshu"), no longer a chancellor. He was also created the Baron of Pingxiang, made an advisor to the Crown Prince Li Xian, and given the honorific title "Yinqing Guanglu Daifu" ().

He also created Li Huaiyuan the Duke of Zhao Commandery and gave him the honorific title "Jinzi Guanglu Daifu" (). In 706, Li Huaiyuan retired again, although when Emperor Zhongzong soon departed the eastern capital Luoyang to return to the capital Chang'an, he put Li Huaiyuan in charge  of Luoyang. It was said that while Li Huaiyuan was greatly honored, he lived a simple and frugal life. He did not build mansions and did not enlarge his garden. He often rode a small horse, and when his fellow chancellor Doulu Qinwang asked him, "You, Duke, are greatly honored. Why not buy a handsome horse?" Li Huaiyuan responded, "I value a horse by its tameness, not by its handsomeness." Li Huaiyuan died in fall 706 and was buried with honor, with Emperor Zhongzong personally writing his eulogy.
