Members contribute to the EU budget roughly in proportion to the size of their economy.
They are most likely to receive big EU cash injections if they are poorer than average, or if they have large, inefficient farming sectors.
The new member states in Central Europe are currently small-scale net recipients, though the flow of funds to them from the EU will grow.
Germany is the biggest net contributor. It receives less from the EU budget than France and Spain, and pays in more.
However, the countries whose net contribution is largest as a proportion of their gross national income are the Netherlands, Sweden and Germany, then the UK, Italy and France.
