The Money Advice Trust (MAT) debt charity is advising consumers who struggle with savings to budget for the year ahead.
One idea, it says, is to join a credit union.
An internet survey conducted for the MAT also suggests that more people will struggle with their finances this January than was the case last year.
Some 16% of people questioned said they were likely – or very likely – to fall behind with their finances in January, as a result of Christmas spending.
That amounts to 7.9 million people, the MAT said, and compares with 11% in a similar poll last year.
The majority – 68% – said they would cope sufficiently during the month.
