Volland, 28, is due to undergo a medical on Wednesday after the clubs settled on a €15.5m fee, bonuses included.
That is considerably less than the €25m being touted by the German press last week, but reflects Volland’s contract situation (one year left).
The ten-time Germany international will sign a four-year deal with Monaco.
#Volland c’est quasi bouclé à #Monaco pour 15,5 millions d’euros bonus inclus. Contrat de 4 ans pour le joueur. Monaco et #Leverkusen finalisent les derniers détails. Visite médicale attendue pour mercredi à Monaco.

Volland has been Monaco’s main target to support Wissam Ben Yedder in their attack since Islam Slimani’s loan spell came to an end.
Bayer coach Peter Bosz today all but confirmed Volland’s exit, along with that of Chelsea-bound Kai Havertz.
“Unfortunately our squad isn’t set yet. I no longer expect Kevin Volland and Kai Havertz to train with us again,” said Bosz. “It’s possible that other players will be on the move as well. In any case, we have to bring in some players, too.”
