And it is calling on the government to accept the report and implement its recommendations in time for next year's budget settlement.
The independent committee was set up by the government earlier this year to examine the system that currently provides additional cash to south-eastern counties, but not to Cambridgeshire.
Last week it announced its recommendations which would scrap the present system and re-allocate the cash around the country.
Conservative leader John Horrell said: 'I have long campaigned to change the Area Cost Adjustment system. It is unfair to our schools and other services in Cambridgeshire.'
Labour leader Janet Jones said: 'The debate about the unfairness of the Area Cost Adjustment system has been raging for many years now. At last we have independent evidence that Cambridgeshire gets a raw deal and we must urge the government to accept the recommendations in time for next year's cash settlement.'
