More than a quarter of people who give money to charity expect to cut donations in the next year, according to a survey carried out for the Charities Aid Foundation.
The survey found 26 per cent of people planned to cut donations in the next 12 months.
But it also found a higher proportion of people planned to cut discretionary spending such as clothes, holidays and socialising than those who expected to reduce their charitable giving.
It found that 37 per cent of people planned to cut down on going for a drink, 36 per cent planned to cut back on takeaways, 32 per cent plan to cut back on holidays and 31 per cent expect to cut back on clothes and on leisure activities such as the cinema.
Only 12 per cent of charity donors said that they are likely to increase their charity donations in the next year, the lowest proportion for any type of spending tested.
The survey was conducted in December among 2,013 adults by the polling firm ComRes. Results exclude those who do not say they participate in each category.
Paul Rees, director of communications at the Charities Aid Foundation, said: "Even in tough times, people are extremely reluctant to cut the generous support they give to for the causes we all care about.
"Britain is one of the most generous nations on earth, but it’s still very worrying that so many people expect to reduce their donations in the next 12 months. If that happens, charities and the causes they support will suffer."
The news follows on from other data collected for CAF in September, which found that 31 per cent of people had reduced their giving in the last 12 months, and only 10 per cent had increased it.
