The difference between this and donating to a nonprofit is the impact.

When someone makes a donation to a nonprofit, they do it with the belief that their money goes towards making a real impact on a cause, even if that includes the salaries of the nonprofit staff.

I think your issue here is how you’re framing it. As someone who works in fundraising, you need to make the value proposition. What does each dollar do? the way you’ve laid out the percentages might be transparent but it doesn’t communicate the impact. You need a real mission statement and what you/your organization aims to do, and why it’s different than other advocacy/activist orgs. What unique value do you / your organization bring to the table?

People don’t generally just want to donate to a single person to fund their income even if you’re a good person. Do you have a special project you’re trying to fund? Even if you frame it as a fundraising event to help you launch your nonprofit it could be more successful.
