Until 1998, Cartwright was paid $30,000 per episode. During a pay dispute in 1998, Fox threatened to replace the six main voice actors with new actors, going as far as preparing for casting of new voices. The dispute was resolved and Cartwright received $125,000 per episode until 2004, when the voice actors demanded that they be paid $360,000 an episode. The dispute was resolved a month later, and Cartwright's pay rose to $250,000 per episode. After salary renegotiations in 2008, the voice actors receive approximately $400,000 per episode. Three years later, with Fox threatening to cancel the series unless production costs were cut, Cartwright and the other cast members accepted a 30 percent pay cut to just over $300,000 per episode.
