Had this debate at work today and thought it was interesting to hear others opinions.
I'm single and most of my colleagues are married/cohabiting. They argued that life in a couple is just twice as expensive but I disagreed.
Some examples:
Housing - mortgage/rent costs are generally halved in a couple
Council tax - a single person receives a 25% discount; this isn't 50%
Utilities - not necessarily halved for a single person - you still have to cook, have lights on etc
Holidays - usually a single person supplement which isn't half price
I've lived as a single person and part of a couple and generally I was financially much better off when cohabitating.
I don't argue that couples may have higher outgoings however aibu to argue that if you are single life costs 50% less?
