The amount of money the population is saving decreased over the autumn, according to National Savings & Investments (NS&I).
On average, Britons are setting aside £82.92 of their income every month, compared with £88.65 a month a year earlier.
The figure also represents the lowest recorded level for the autumn since the survey began and is down from the amount saved in the summer of £87.37 per month.
NS&I said the drop could be a result of income levels declining compared with 12 months ago.
In that time, average monthly take-home income has fallen from £1,384.20 in autumn 2009 to £1,239.10 this year.
On average, only half of the population (50%) said they save money every month, while the actual amount these people are managing to set aside has dropped to the lowest level seen since autumn 2006.
"Many people may be feeling the squeeze with just one week to go until Christmas," said Tim Mack, savings spokesman at NS&I.
"The festive period can be an expensive time but there are still savings to be made, if you're prepared to shop around.
"Being smarter in planning your spending by looking for promotional offers, buying cheaper brands and not leaving too much to the last moment are simple ways to make extra savings this year.
"This will ensure you're not left with the festive financial blues in the New Year."
Looking ahead, the survey found that people are slightly more optimistic about their savings in the coming year.
On average, 29% of savers think they are more likely to save in 2011.

"Many people appear to be approaching the New Year as an opportunity to review their finances and start 2011 on the right track."
