Tim will get to keep £172 more of his £40,000 salary next year thanks to the increased personal allowance (which is £8,105 in 2012/13). His moderate drinking and smoking will cost him £38 more in the next 12 months, after a packet of cigarettes increased by 37p, a pint of beer by 3p and a bottle of spirits by 41p. Tim’s average car usage — 3,000 miles — will cost him just £20 more.
