The "standard" for a good charity is around 75%.
From NYPost
The Clinton family’s mega-charity took in more than $140 million in grants and pledges in 2013 but spent just $9 million on direct aid.
The group spent the bulk of its windfall on administration, travel, and salaries and bonuses, with the fattest payouts going to family friends.
On its 2013 tax forms, the most recent available, the foundation claimed it spent $30 million on payroll and employee benefits; $8.7 million in rent and office expenses; $9.2 million on “conferences, conventions and meetings”; $8 million on fundraising; and nearly $8.5 million on travel. None of the Clintons is on the payroll, but they do enjoy first-class flights paid for by the foundation.
In all, the group reported $84.6 million in “functional expenses” on its 2013 tax return and had more than $64 million left over — money the organization has said represents pledges rather than actual cash on hand.
But that’s still far below the 75 percent rate of spending that nonprofit experts say a good charity should spend on its mission.
Charity Navigator, which rates nonprofits, recently refused to rate the Clinton Foundation because its “atypical business model . . . doesn’t meet our criteria.”

This is without the overwhelming evidence of influence buying at the Clinton foundation, their suspicious bookkeeping, etc.
