I’m happy to support by purchasing from businesses that support charity, or are produced by charities & will pay an extra 10-15%, but have a caveat re how much goes to charity &, what format that charity is provided.
I tend to give religious based charities a miss as they often have proselytising as one of their major focuses.
I still don’t think there is a way, in Australia, of rating charities that is transparent enough.
A charity may raise millions but give thousands, or nothing.
My concerns are quite well summarised by @panlezark I lack the tools by which to compare charities. I would like to think that a high proportion of my donation goes to the actual cause but charity ‘expenses’ can cover a multitude of sins. With ThankYou I was impressed with the information I found on their website, particularly the number of high profile partners. I also rely on studies such as your own to shed light on the workings of individual charities. I have formed the impression that there are far too many charities in Australia, many of which are little more than businesses using the charity label to gain competitive advantage.
It doesn’t appear to be supported in the Australian Amazon website, but I have a browser extension called ‘Smile Always’ that directs any Amazon US requests to smile.amazon.com. Why do this? Because Amazon will then donate a portion of what I spend (on some product lines only) to a charity of my choice.
Similarly, if you buy computer games - as well as occasional bundles of digital or audio books and comics - then Humble Bundle allows you to nominate a charity when shopping there, and is expressly focused on making sure 5% of all revenue goes to charity.
Both of these are focused on US and international charities, and only give a portion of the sales price to charity, but every little bit (over $129m since 2010 according to Humble) helps.
There are other, similarly charity-focused groups popping up all over the place. I heard recently of a US mattress company that donates every 11th mattress to homeless charities.
The only independent charity comparison org i know is GiveWell.org but their charities are specifically health related overseas.
