A survey has revealed that couples who have been together for between 11 and 15 years tend to spend the most on one another at Christmas time, but after that, the generosity begins to fall away.
The research, commissioned by buy now pay later provider Clearpay, put the average festive gift spend in that group at £243, against an overall average of £193.
But the generosity does not last, according to the findings.
Once a relationship passes the 15-year mark, the typical budget falls back to £189 for couples who have been together for 16 to 20 years.
For those in relationships of more than 20 years, it edges down again to £180.
Clearpay commissioned Opinium to survey 4,000 people across the UK in October.
