This free PCN calculator helps GP practices, practice managers and Primary Care Networks estimate funding for 2026/27. It works as a practical ready reckoner, PCN funding calculator, ARRS calculator and GP funding calculator in one place, bringing together indicative planning values for ARRS, IIF, enhanced access, Core PCN funding, care home premium and practice-level GP reimbursement funding.
Use the calculator to select your PCN, review network practices, test ARRS workforce scenarios and explore funding summaries. The tool is intended for practical planning support and quick board-level discussions rather than as a substitute for formal financial advice or local ICB confirmation.
What is included
ARRS ready reckoner, enhanced access, IIF and the practice-level GP reimbursement scheme using £4.57 × practice adjusted population.
Who it is for
GP partners, PCN Clinical Directors, practice managers, federation leads and analysts supporting NHS primary care planning.

Transitional additionality note: NHS England supplementary 2026/27 GP contract information confirms exemptions allowing GPs plus Band 5 and Band 6 practice nurses previously funded via Capacity and Access Payment or PCN Test Sites to transition into ARRS where funding exists; other PCN staff funded by those sources may also transition into ARRS. This note is based on the official NHS England supplementary information only.
