Your effective tax rate is 37.2%, but the rate on your next pound is higher: of the next £100 you earn you'd keep £38. Your employer also pays about £17,700 employer National Insurance on top, so you cost them around £140,700 a year.
Part of your salary is above £50,270, so it's taxed at the 40% higher rate and National Insurance drops to 2% on that part.
Above £100,000 your personal allowance shrinks by £1 for every £2 you earn, so each extra £100 here costs about 62% in tax and NI. Paying more into a pension can win the allowance back.
