The Market Forces Factor (MFF) is an estimate of unavoidable cost differences between healthcare providers, based on their geographical location. Each NHS organisation an individual MFF value.
In 2019/20 the NHS revised the calculation method and data used for the MFF, assigning new MFF values to all organisations. The new values are being phased in over a five-year period in equal steps.
