The survey, carried out by Croner Reward, found the average basic pay for all marketers in the North West is £30,000 per annum - 5.1% below the national average.
Basic pay for marketing managers stands at £42,000 on average, 2.3% below the national average. Those performing the same role in London can expect to earn £44,000.
But the CIM says pay at senior levels remains competitive. A head of marketing in the North West earns a basic salary of £58,334, whilst a marketing director earns £76,750 - both slightly above the national average for these roles.
Across the UK as a whole, the survey showed that average pay for marketers increased by 3.3% over the past year, and is forecast to rise by 3% in the year ahead.
David Thorp, director of research and professional development at The Chartered Institute of Marketing, said; "Marketers in the North West had better ensure they reach senior positions quickly if they want to achieve the pay levels seen elsewhere in the UK."
"One way of doing so is to become professionally qualified, which as the survey indicates, results in higher salaries. In what promises to be a continuing challenging business environment over the next few years, employing qualified marketing professionals, who will undoubtedly help their organisations thrive and survive, will prove to be money very well invested."
