Your donation is subject to a 2.7% + $.30 processing fee.  This is an unavoidable cost of using your card.  But other than that all of your donation will come to the Museum and be used to improve the permanent collection and run the museum.  Remember we are tax-deductible non-profit, so no one is getting rich from your donation.  All of your money goes to supporting the mission of the museum.
