Nearly two-thirds of performers (63%) earned less than 5,000 pounds from their profession last year, according to the survey.
It's an improvement of 77% of analysts from 2014 for actors, musicians and dancers from the entertainment company for recreation Mandy Network.
But the latest poll found that half the 3,000 members who responded took unpaid roles every year.
And 60% had to take a second job out of the fun in order to fit the ends.
One out of five had no paid work in the entertainment industry for the past six months, while only 13 percent of the home accounted for more than £ 20,000 a year, the survey said.
The story of Annameka
Actress Annameka Porter-Sinclair told the BBC she graduated from the British School in South London in 2006 and earned a job as a film racer, thinking it could be the "back door" in the industry.
But she later found that she was "a dove [in production]… so it was unsuccessful. "
Annameka then worked in a call center, and later in the sale of the exhibition, which gave her the flexibility to go to auditions.
"I entered this when I was 15 years old, now I am 35 years old, and I did not give up," she says.
"I have not changed my agent recently, I am not ashamed because I love what I do, but I do not have what a normal adult will have at age 35. Income is more at the student / internship level.
"Everybody so often gets a commercial, which is a big part of your income for the year, but it's never consistent."
Annameka appeared in films, including Payback (2012) and TV-campaigns for hobbies, Hovis, Heinz, Channel 4, EE and Tesco, along with her theatrical work.
She also says the industry is "the perfect place to think about mental health issues".
The findings of the report also suggest that some people working in the industry have mental health problems, with 63% of women and 48% of respondents struggling with anxiety.
They also found that 59% of women and 61% of men suffer from stress, while 37% of women and 36% of men say they have had a depression.
Annameka says: "Your family members and friends are trying to be supportive, but you know that they are wondering if you are doing the right thing, they do normal things, while you are almost permanently unemployed and have a passion that is not lit up fully to you feel unfulfilled. "
Annameka founded an acting society in 2009 and "invited many casting directors, which was really useful".
She adds, "I learned about the industry. Cast managers are the gateway to jobs.
Philip Gold, chief executive of The Mandy Network, said the survey found it hard to break into the industry if you do not have other means to support yourself.
"Since this industry continues to criticize the lack of diversity, too many of the significant job opportunities are still being handled behind closed doors, while wage levels dictate that only financially secured or those with other income streams can really afford to stay in the long-term sector, "he said.
Mundy also examined the members of the film and the television crew. While the salary between the crew is greater than among the performers, 54% of crew members still earn less than £ 10,000 per year, 13% unpaid work each month, and 12% can not find paid work in the past six months.
A spokeswoman for the creative union Equity said: "The approach to work in the entertainment and creative industries should be talent.
"Our industries will only progress by attracting and retaining professional talent, regardless of the background or circumstances.
"The disgruntled audience wants and expects to see and hear themselves reflected authentically and its expectations are even higher than public theaters and broadcasters."
The report also showed evidence of a gender imbalance within both pay and opportunities.
Eight-two per cent of women earn less than £ 10,000 per year, compared to 69% of men, while 63% of women have a second job out of the party to help support, compared to 57% of men.
The Mendi Network carried out an online survey of 3,067 of its members between 12th and 30th October 2018.
