Charity Navigator is an independent American nonprofit corporation that evaluates charities in the United States. Its stated goal is "to advance a more efficient and responsive philanthropic marketplace in which givers and the charities they support work in tandem to overcome our nation’s and the world’s most persistent challenges." 
Charity Navigator was launched in spring 2001, with the mission of helping "donors make informed giving decisions and enabling well-run charities to demonstrate their commitment to proper stewardship" of donor dollars. Initially, Charity Navigator provided financial ratings for 1,100 charities. Charity Navigator currently evaluates more than 5,400 charities in the United States in addition to hundreds of organizations with international operations.
The site also features opinion pieces (articles and two blog sites) by Charity Navigator experts, donation tips, and top-10 and bottom-10 lists that rank efficient and inefficient organizations in a number of categories. Annually, Charity Navigator conducts a national study to determine and analyze any statistical differences that exist in the financial practices of charities in metropolitan markets across America.
The service is free, and the site is navigable by charity name, location or type of activity. Charity Navigator is a 501(c)(3) organization that accepts no advertising or donations from the organizations it evaluates.
In 2006 Time magazine named it in one of the 50 top websites of the year. In 2011, Kiplinger's Personal Finance selected Charity Navigator as a Money Management Innovation for "helping millions of people become philanthropists", putting it in the same category as Mint.com, TurboTax and Mobile Banking Apps.
Using publicly available tax returns (IRS Form 990) filed with the Internal Revenue Service and information posted by charities on their web sites, the Charity Navigator rating system bases its evaluations in two broad areas — financial health and accountability/transparency. Based on how the charity rates in each of the two areas, it is assigned an overall rating, ranging from zero to four stars. To help donors avoid becoming victims of mailing-list appeals, each assessment of a charity's performance is accompanied by a review of its commitment to keeping donors' personal information confidential.
This method was criticized in an article in the Stanford Social Innovation Review for taking into account only a single year's IRS Form 990. This can lead to significant fluctuation in the ranking of a charity from year to year. Also, the focus on the IRS Form 990 has itself been criticized, as the accuracy and reliability of IRS Form 990 data is questionable. Form 990 categorizes a charity's expenditures into three broad categories that are open to accounting manipulation. The nonprofit sector does not have the strict financial regulation and transparency required from public corporations (under the Securities Act of 1933, the Securities Exchange Act of 1934, and the Sarbanes-Oxley Act, among others), creating limitations on how accurately a charity's efficiency can be graded based on a tax return. Particularly relevant to Charity Navigator's methodology is that 59% of the 58,000 charities receiving public donations in 1999 failed to report any fundraising expenditures, illustrating a potential problem with relying on Form 990 figures alone when analyzing an organization.
However, Charity Navigator never included charities that claim to have no fundraising expenditures. Furthermore, it only rates the 6% of charity organizations in the US that have over $1 million in annual revenue (these 6% get 94% of the revenues that come into the nonprofit sector each year), and argues these charities have better expertise for reporting to the IRS, are under greater public scrutiny and therefore their reporting tends to be more accurate.
As of December 2007, Charity Navigator would recommend donors support concerns that meet six criteria:
- Able to communicate who they are and what they do
- Defined short-term and long-term goals
- Able to state the progress it has made (or is making) toward its goal
- Programs make sense to the donor
- Programs that the donor feels they can make a long-term commitment to
In December 2008, the President and CEO, Ken Berger, announced on his blog that the organization intends to expand its rating system to include measures of the outcomes of the work of charities it evaluates. This was described in further detail in a podcast for The Chronicle of Philanthropy in September 2009. The article explained that plans for a revised rating system will also include measures of accountability (including transparency, governance and management practices) as well as outcomes (the results of the work of the charity).
In July 2010, Charity Navigator announced the first major revamping of its rating system. This revamping begins what the organization states is the process to move toward CN 3.0, which is a three dimensional rating system that will include what they consider the critical elements to consider in making a wise charitable investment - (1) financial health (Charity Navigator evaluated this from its inception), (2) accountability and transparency (begun in July 2010) and (3) results reporting (slated to begin rating this dimension in July 2012). After collecting data for more than a year, in September 2011 Charity Navigator launched CN 2.0, which is a two-dimensional rating system that rates a charity's (1) financial health and (2) accountability and transparency.
In January 2013, Charity Navigator announced another expansion to its rating methodology, "Results Reporting: The Third Dimension of Intelligent Giving." Because mission-related results are the very reason that charities exist, Charity Navigator developed this new rating dimension to specifically examine how well charities report on their results. Charity Navigator's website explains the new methodology and its plans for the future.
In recent years, Charity Navigator has become outspoken against what it calls high CEO compensation. At the same time, they note that nonprofit CEOs should be paid what the market demands. They complete a CEO compensation study each year. In the study, they have consistently argued that a low six figure salary for a CEO of a mid-to-large sized nonprofit is the norm and should be acceptable to donors. They further argue that these are complex multi-million dollar operations that require a high level of expertise. They are however, outspoken against the phenomenon of million dollar plus compensation, which they do not believe is justified for a tax exempt public charity.
