The McDonald’s Monday Effect: Is Consumer Spending Shifting?

McDonald’s has made Monday a focal point of its UK promotional strategy through its recurring McDonald’s Mondays offers. The initiative is designed to encourage customer visits on what has traditionally been a quieter trading day for the quick service restaurant (QSR) sector.

But are these promotions actually influencing consumer spend?

Using our anonymised consumer transaction data, we investigated whether Mondays stand out for McDonald’s in the UK relative to both its domestic competitors and comparable European markets.

The results reveal that Mondays are a uniquely strong day for McDonald’s in the UK:

While weekend spending remains dominant across all markets, the UK’s Monday share is notably higher than those observed in France and Italy and marginally higher than Germany.

Across the QSR sector, spending generally builds toward Friday and the weekend. While McDonald’s follows this pattern too, Mondays carry a noticeably larger share of weekly spend than competing brands. In fact, for McDonald’s, Monday spend exceeds Tuesdays and is on par with Wednesdays. KFC and Burger King record Monday as either their weakest or second-weakest day of the week.
