GP practices in North Norfolk - the highest-funded area - receive £215.13 per weighted patient, data from the Health and Social Care Information Centre (HSCIC) reveal.
Practices in West Lancashire, which is the lowest-funded area, receive just £105.19 - less than half the North Norfolk total.
Average funding per patient across all GP practices for 2014/15 was £141.09, the data show, up from £136.01 for 2013/14 - the first year in which payment data by GP practice was published.
Practices on APMS contracts receive the highest level of funding per patient, at £189.74. This is almost 40% more than the £137.05 per patient GMS practices receive. PMS practices, meanwhile, receive £143.84 per patient on average.
The huge gaps in funding per weighted patient between CCG areas are also influenced by factors including practices' dispensing status and enhanced services income.
The 20 practices in North Norfolk shared more than £16m in dispensing and drug reimbursement funding, while the 22 practices in West Lancashire received just £404,000 between them.
West Lancashire practices also earned little from local enhanced services in 2014/15 - sharing just £10,261, compared with £949,777 for the North Norfolk practices.
