£31,000 after tax in Cambridge — what you take home

£31,000 is 1.3× the National Living Wage (£12.21/hr full-time, roughly £23,810/year) and is below the UK full-time median of £34,963. Compared to the Cambridge median full-time salary of £40,000, you are £9,000 below the local average — a ratio of 0.78×.

The real test of £31,000 in Cambridge is what is left after rent. A typical 1-bed flat in Cambridge is about £1,500/month — that is 70% of your monthly take-home, which is unaffordable on this salary alone — most renters would need flatmates or a partner. After rent you would have £653/month (£7,836/year) for bills, food, transport, saving and discretionary spend. A healthy 30% rent budget at this salary would be £646/month. In raw working hours, you need roughly 114 net hours to cover one month of rent at £13/hr. Because rent in London is around £2,100/month against £1,500/month in Cambridge, the same £31,000 leaves a Cambridge renter roughly £600/month (£7,200/year) better off than a London renter — even though tax and take-home are identical.
Income tax and National Insurance are set nationally, so £31,000 in Cambridge delivers exactly the same £25,840 take-home as it would in any other English city. What changes between cities is cost of living — chiefly rent. In the Basic Rate band, a Stocks & Shares ISA (up to £20,000/year, tax-free) is the most efficient vehicle to grow savings. Saving 20% of take-home (£431/month) would fill the ISA allowance in 47 months.
