Prince William, as the Duke of Cornwall, earned approximately £22.9 million (about $30.8 million) in the 2024-2025 financial year from the Duchy of Cornwall. This income, generated from the estate established in 1337, covers the private and charitable expenses for him, his wife Princess Kate Middleton, and their three children. This marks William's second year managing the Duchy, which focuses on community empowerment, environmental initiatives, and supporting tenants.
