Evaluate the structural financial resilience of your organization by measuring operational resource allocation and funding concentration risks.
Government Reliance Ratio (GRR) = (Government Grants / Total Revenue) × 100
Personnel Expense Ratio (PER-Staff) = (Staff Costs / Total Expenses) × 100
Administrative Expense Ratio (AER) = (Administrative Expenses / Total Expenses) × 100

Nonprofit organizations face unique financial challenges that standard business metrics cannot always capture. The Charity Operations Calculator is designed to evaluate the structural health of an organization by analyzing two critical areas: where the money comes from (Revenue Risk) and how the money is spent (Operational Efficiency). Unlike simple budgeting tools, this calculator focuses on ratios that indicate long-term sustainability and resilience against external shocks.
The first critical metric provided by the Charity Operations Calculator is the Government Reliance Ratio (GRR). Many non-profits rely heavily on state or federal grants. While stable, these funds often come with strict restrictions and are subject to political shifts. A high GRR indicates that the organization is vulnerable; if a single grant is not renewed, operations could collapse. By identifying this risk early, executive directors can strategize to diversify income streams through private donations or earned income.
On the expenditure side, the tool calculates the Personnel Expense Ratio (PER) and the Administrative Expense Ratio (AER). In the non-profit sector, human capital is often the primary driver of mission delivery. As noted by the National Council of Nonprofits, investing in staff is investing in impact. A healthy PER reflects a commitment to the workforce delivering the services. Meanwhile, the AER provides a check on overhead. While the "overhead myth" has been debunked, maintaining a reasonable balance is still essential for donor trust and operational agility. For more on organizational structures, Wikipedia offers a comprehensive overview of the sector's regulatory and operational standards.
Using the Charity Operations Calculator allows board members and leadership to move beyond raw numbers and understand the story their finances are telling. It bridges the gap between accounting data and strategic planning.

There is no single rule, but a ratio above 50-60% is generally considered high risk. If government priorities change, the organization loses the majority of its funding. Ideally, a diverse mix of government, private foundation, individual, and earned income is best for stability.
Not necessarily. For service-based charities (like counseling centers, schools, or elder care), the "product" is the staff's time and expertise. In these cases, a PER of 70-80% is normal and healthy. It indicates resources are going directly to mission delivery via staff.
The AER tracks how much of your budget goes to "keeping the lights on" versus program activities. While overhead is necessary, donors often look for an AER between 10% and 20% as a sign of efficiency. However, be careful not to under-invest in infrastructure, which can hurt long-term growth.
This typically includes general management salaries (Executive Director, HR, Finance), office rent, utilities, insurance, audits, and legal fees. It excludes costs directly tied to delivering specific programs.
