The Uzumaki clan are known for their high chakra reserves and strong life force.....Nagato fought whole Konoha, pulled of a large scale shinra tensei, fought naruto in sage mode, then in his six tailed form, still was able to create a massive chibaku tensei .....and still had enough chakra to revive the people he killed in Konoha via Rinne tensei
So it's pretty obvious his chakra levels> jiraiya's
