Molly is correct that they can mean the same thing. I want to make it clear that one is usually used for one purpose and the other usually has the other: An American English point of view Owe = normally used when money or debt is involved I owe you so much for saving me. Due = normally used as a replacement of because It is due to a flat that I am so late.

They can both mean the same thing. They can both mean 'because'. His leg hurt due to all his hard work. His leg hurt owing to all his hard work. They can both refer to a debt. He still had twenty dollars owing to him for the work he did. He still had twenty dollars due to him for the work he did. Due to may also mean entitled. He was respected due to his integrity.
