It would be worth at least $4.5 million, but the Serbian is not eligible for it because he has missed more than three Masters tournaments this year. One of the reasons is that Djokovic was not allowed to enter the United States because he has not been vaccinated against covid-19, so he did not play in the tournaments in Indian Wells and Miami. Later, he missed the Masters in Madrid (due to injury), Montreal and Shanghai and thus did not meet the quota required to earn the bonus.
