During Shakespeare's time, playwrights were typically paid a set fee for their work, rather than a percentage of the profits from ticket sales. The fee for a new play ranged from £5 to £10, with some playwrights receiving as much as £20.
Shakespeare likely started with a relatively low fee, but as his popularity grew, so did his earnings. By the late 1590s, he was receiving around £20 per play.
In addition to the initial payment, Shakespeare also received "benefit performances" for certain plays. These were special performances where a portion of the profits went directly to the playwright. Depending on the success of the play, these benefits could amount to a significant sum of money.
In later years, Shakespeare became a shareholder in the Globe Theater, which gave him a share of the theater's profits. This arrangement further increased his financial success.
Overall, while it's difficult to determine an exact figure for Shakespeare's earnings per play, it is clear that he was financially successful and one of the most well-paid playwrights of his time.
