Plan B is that you raise a million, invest it, and spend 75k a year every year on grants in perpetuity. Any additional funds are added to the endowment.
I know it's an entirely different charity, but Comic Relief and Children In Need run on this basis. It does make sense, but I do wish that they wouldn't keep spinning the line that 'every penny you give tonight can be helping somebody in desperate need tomorrow'. There's a reason why they don't say "give us your pocket money, kids, and we'll invest it in some quite possibly very shady projects and then, maybe by next year's CR night, some of it will have been granted to a good cause - which the general population may or may not believe is a worthy cause."
Charity threads are always the same. Lots of posters who think charities run themselves, that nobody should be paid, or if they are paid it should be minimum wage.
There are some hugely unrealistic people who think that any costs or wages paid by a charity are 'theft' or 'misappropriation of funds'; but I think the pendulum can swing far too far the other way. Of course, nobody should be out of pocket, but I think the living wage should be the standard for a lot of charities, especially as many of them also rely on volunteers who are paid nothing at all.
Charities like the Salvation Army and Islamic Relief seem able to pay their top people decent, non-excessive wages. Others will disagree, but I think taking a job running a charity from the top shouldn't be for the same motive as it would if you were being employed as CEO of E&Y or Unilever.
If your only motivation for taking the job - however well the figures perform under your leadership - is to coin it in off the back of a charity, I don't think you're the right person for the job at all. Why is it fair for everybody under you to work for a lower wage, or for no wage at all - because they believe in and support the charity - but when it comes to you, it's all comparisons with 'what you COULD earn in private industry' and justifications why you shouldn't lose out at all.
To me, it just has shades of the government seeing a subsidised bar and outrageous 'expenses' as a fair 'reward' for how brilliant they are, but when it comes to the poor in society, it's just assumed that you're disgraceful for hoping that you might be able to stay warm and also not regularly go hungry.
I'm also uncomfortable with the whole idea of 'ROI' as applied to a charity. I know that big charities often have to be run as businesses - and of course they will incur considerable costs - but it leaves a nasty taste when people's often sacrificial giving to what they believe is a worthy cause is considered a 'return', just the same as if it were from customers of a business choosing to pay money in return for getting something that they want.
Put crudely, I could regularly stand in the street collecting 'for X charity' and pass on 50% of what people give me to the charity, spending the rest on posters, flyers and megaphones to announce that I would be collecting, and some money for my own efforts.
The charity would be benefitting much more than they would if I didn't stand there collecting, but I don't think givers would be very happy to know that they had given a tenner of their hard-earned money in order for the charity to end up with a fiver. Even if I insisted to them that my ROI was quite reasonable, they would quite rightly tell me that it was ultimately their investment and not mine at all.
