The UK's overall net contributions are even higher than those shown in the official EU budget. The UK also pays further amounts to the EU which are not formally included in the EU's budget, and which do not appear in any summaries you will read in the British media or in House of Commons Library report,eg administrative costs, co-funding of EU projects.
The new EU budget plan seeks to fill the roughly €12-15 billion annual hole left by Brexit (Budget Commissioner Gunther Oettinger), which is what UK has been paying in.

The Commission has proposed changes to the current overall financing – “Own Resources” – system and diversifying the budget’s sources of revenue.
The proposed new own resources include:
1)20 percent of the revenues from the Emissions Trading System
2)A 3 percent call rate applied to the new Common Consolidated Corporate Tax Base
3)A national contribution calculated on the amount of non-recycled plastic packaging waste in each country.
These proposed taxes will disproportionally hit UK compared to other EU countries.

The increase in GNI and the inrcease to 1.11% take of that GNI by the EU together with no rebate and the extra revenues means UK will be paying about £22 bn pa if we were to stay in the EU.
