On preparing to attend the event, 31 per cent more men than women fell into the “sensible” category in the study on hen and stag spending habits by offer website iLikeOffers.co.uk.
Nearly a third of lads said they planned a budget and stuck to it, compared to one-in-five women.
While one in seven men said they felt stag parties had become too long, expensive and involved in recent years, a third admitted following rigid saving plans to attend, compared to nine per cent of women.
Chris Perrett, of iLikeOffers, said: “This is the kind of careful organisation we would associate more with the female population, but there’s clearly no accounting for the motivational power of stag dos.
“So sacred is the event that three-quarters of male participants admitted to prioritising the stag over the wedding in terms of spending. This research re-affirms what we’ve suspected: bachelor parties are serious business for the men of Britain.”
