The calculator, developed by Leeds Building Society (LBS), shows what they could accrue by putting the money into a savings account instead.

Research by LBS – based on data from YouGov – found UK adults who buy cigarettes spend an average of £24.62 per week on tobacco, while the average British adult who spends money on nights out on a weekly basis spends £23.72 in pubs, bars and clubs each week.

Those who buy alcohol for consumption at home on a weekly basis will spend an extra £10.72.

Gary Brook, head of corporate communication at Leeds Building Society said, “Some people may be surprised to see the cumulative cost each week of their lifestyle, and what savings they are missing out on.”
