The Third Sector information page lists the top 100 salaries for charities 2019.
Top of the list is £3.17m paid to the CEO of the Wellcome Trust. 286 of their staff are paid more than £60k. Some other notable ones include The Consumers' Association at £825,000, The City and Guilds of London Institute at £690,000 and The Royal Opera House at £794,591. Macmillan Cancer pays £180,000 and has 102 staff over £60,000. Marie Curie pays £160,000 with 54 staff paid over £60,000. Nuffield Health pays £520,000 with 342 staff on over £60,000.
Bottom of the Top 100 list are all over £140,000.
Other well known names include: Marie Stopes International £300,000, The Girls' Day School Trust £266,000 (plus 98 staff on over £60,000), Church Commissioners for England £264,000, Nursing and Midwifery Council £237,000, Save the Children International £230,000, Eton College £205,000, RSPCA £200,000, RNIBP £190,000, British Heart Foundation £179,000, Motability £177,500, British Red Cross £173,000, Age UK £170,000. VSO £160,000 and so on.
The bottom 13 Charities on the list pay between £140,000-£150,000. These are, in descending order: 88: Action for Children, 89: Citizens Advice, 90: Oxfam, 91: St Mungo Housing, 92: RSPB, 93: Save the Children (plus their international salary noted above), 94: The British Academy, 95: RVS, 96: The National Autistic Society, 97: Methodist Independent Schools Trust, 98: Sue Ryder, 99: PDSA, 100: Methodist Homes.
So, the OP works for one of these. Not bad salaries really and they definitely have the scope to move to well paid Government jobs, higher up the Charity sector and Quangos for way more money if they are at the bottom end.
It is not reported how many are £100,000 plus but I suspect a hell of a lot.
