Eight Financial Ratios Every Nonprofit Board Should Review

Most nonprofit boards receive financial statements every quarter. Fewer understand what those statements are actually telling them. Financial ratios give the numbers meaning. They answer the questions board members actually care about: Can we make payroll if a major grant falls through? Are we spending enough on programs to satisfy donors and watchdog agencies? Is our fundraising generating a real return?

• Eight nonprofit financial ratios cover the full picture. Liquidity, mission efficiency, fundraising performance, and sustainability each require different metrics. No single number tells the whole story.
• Days cash on hand and operating reserves are the two most critical survival metrics. Target three months of cash and three to six months of unrestricted net assets. Organizations dependent on government grants or a single funder should aim toward the higher end.
• The program expense ratio is the most scrutinized number donors and watchdog agencies use. Most charities rated by Charity Navigator spend at least 70% of expenses on programs. The BBB Wise Giving Alliance sets 65% as the minimum floor, with 80% being the recommended target ratio.
• Revenue concentration is one of the most important ratios most boards never track. Any single source representing more than 30% of total revenue is a material risk worth a formal board conversation.
• A modest operating surplus is not optional. It is how nonprofits build resilience. Persistent break-even budgeting leaves no room for unexpected expenses, strategic investment, or reserve building.

The Eight Ratios at a Glance

Liquidity: Can You Cover the Next Three Months?

Liquidity ratios tell you whether your organization can meet its obligations in the short term. They are the first place to look when cash feels tight, and they are among the most important numbers a board can monitor.

Current Ratio: Do You Have $1 for Every $1 You Owe?

The current ratio compares assets that can be converted to cash within one year against liabilities due within the same window.

Formula: Current Assets / Current Liabilities

At 1.0, you have exactly one dollar of liquid assets for every dollar owed. Below 1.0, short-term obligations exceed what you can readily access. This is a warning sign. Most well-run organizations target 1.5 or higher to create a buffer for delays in grant payments or seasonal revenue dips.

One thing to watch: restricted funds sitting in current assets may not be available to cover general operating obligations. When reviewing this ratio, your finance team should clarify how much of your current assets are genuinely unrestricted.

Days Cash on Hand: How Long Can You Operate Without New Revenue?

This ratio translates your cash position into something a board can immediately relate to: how many days of operations your organization can sustain without receiving any new revenue. Depreciation is excluded from the denominator because it does not require a cash outlay.

Formula: Unrestricted Cash and Liquid Investments / (Annual Cash Operating Expenses / 365)

Organizations with predictable, diversified revenue can operate comfortably at the lower end of the three month range. Those heavily reliant on government grants or a single foundation funder should aim higher, since grant payments are frequently delayed and renewal cycles create gaps. As the CPA Journal notes, many organizations maintain a policy of two to three months of reserves at a minimum, with higher liquidity preferred for those with more variable funding.

Operating Reserve Ratio: How Many Months of Cushion Do You Have?

Where days cash on hand measures your immediate runway, the operating reserve ratio measures your longer-term financial cushion. It shows how many months your organization could sustain operations using only its unrestricted net assets.

Formula: Unrestricted Net Assets / Average Monthly Operating Expenses

The widely cited target is three to six months of expenses. Below three months signals vulnerability. An organization with fewer than 30 days in reserve has very little room for a funding disruption, a major unexpected expense, or a slow-paying grant agency.

For Colorado nonprofits that rely on a mix of state contracts, foundation grants, and individual donations, building reserves to the three-month mark is a realistic and worthwhile goal for the board to set explicitly as a financial policy.

Mission Spending: How Much Actually Goes to Programs?

Donors, grant makers, and watchdog organizations pay close attention to how a nonprofit allocates its spending. These ratios show whether resources are flowing toward programs or being absorbed by overhead.

Program Expense Ratio: The Number Donors Look at First

The program expense ratio is the most widely watched nonprofit financial ratio. It measures what percentage of total expenses go directly toward mission-related activities, as opposed to administrative overhead or fundraising costs.

Formula: Program Service Expenses / Total Expenses

The Charity Navigator rating system uses the program expense ratio as one of its core Accountability and Finance metrics, with most top-rated charities spending at least 70% of expenses on programs. The BBB Wise Giving Alliance requires a minimum of 65%. Most well-managed nonprofits target between 65% and 80%, balancing program investment against the administrative and fundraising capacity needed to sustain the organization.

A ratio above 90% can sound impressive but occasionally signals underinvestment in infrastructure, technology, or staff development. A newer nonprofit scaling rapidly may carry a lower ratio temporarily. An established organization with volunteer-heavy programming may run higher. The board should set a target range and review trends over time rather than fixating on any single year.

Administrative Expense Ratio: What This Number Does and Does Not Tell You

This ratio measures what share of total spending goes toward organizational overhead: executive leadership, finance, human resources, technology, facilities, and similar costs.

Formula: Administrative Expenses / Total Expenses

A general benchmark is below 35%, though most healthy organizations run well below that. In its September 2023 methodology update, Charity Navigator removed three expense-based metrics from its rating system. These included the administrative expense ratio, the fundraising expense ratio, and program expense growth.

The change reflected a growing recognition that the sector had overcorrected in response to the “overhead myth.” This is the idea that any spending on administration is wasteful. Organizations that starve themselves of infrastructure, talent development, and technology to chase a favorable ratio often end up less effective at delivering their mission.

Other donors and watchdog groups still look at this number, and the BBB Wise Giving Alliance continues to use overhead thresholds in its standards. Your board should understand where it sits and be prepared to explain unusual results in context.

Fundraising: Is the Investment Producing a Return?

Fundraising Efficiency: What It Costs to Raise a Dollar

This ratio measures the return on your fundraising investment. Higher is better: it means you are generating more revenue per dollar spent on fundraising activity.

Formula: Total Contributions / Fundraising Expenses

A ratio of 5.0 means the organization raises five dollars for every dollar spent on fundraising. The $0.20 per dollar raised benchmark (equivalent to a 5.0 ratio) has been a long-standing industry reference point. While Charity Navigator removed the fundraising expense ratio from its scoring formula in 2023, it still displays the metric on individual charity profiles.

Many donors and grant makers continue to use it when evaluating organizations. The BBB Wise Giving Alliance separately requires that fundraising expenses not exceed 35% of related contributions.

This ratio is most useful when evaluated by campaign or revenue channel rather than in aggregate. A gala event and a direct mail campaign will have very different efficiency profiles. Your finance team should be able to break this down by fundraising type so the board can make informed decisions about where to invest and where to pull back.

Revenue Concentration: A Risk Most Boards Don’t Track

This ratio does not appear on most standard watchdog checklists, but it is one of the most practically important metrics for board oversight. It measures how much of your total revenue comes from a single source, whether that is one foundation, a government contract, a single major donor, or program service fees from one client.

Formula: Revenue from Largest Single Source / Total Revenue

A concentration above 30% is a signal worth discussing at the board level. An organization receiving 60% of its revenue from one government contract is materially exposed if that contract is not renewed, reduced, or delayed. Diversification of revenue across individual donations, grants, program fees, and earned income is one of the strongest indicators of long-term sustainability. This is a ratio that belongs in every board’s regular reporting package, even though it is rarely listed alongside the traditional ratios.

Sustainability: Is the Organization Building Reserves?

Operating Margin: The Case for Running a Small Surplus

There is a persistent misconception that nonprofits should not run a surplus. In reality, a modest positive operating margin is how organizations build reserves, retire debt, invest in technology, and weather downturns. Running at break-even year after year leaves no room for unexpected expenses or strategic investment.

Formula: (Total Revenue − Total Expenses) / Total Revenue

A small, consistent surplus is healthy. Persistent deficits erode net assets and eventually threaten the organization’s ability to continue operating. The board should review operating margin trends over three to five years, not just the current year, and understand whether deficits reflect strategic investment or structural financial stress.

Your Ratios Are Only as Good as Your Books

Financial ratios are only as trustworthy as the data behind them. If your accounting records contain errors, if expenses are misclassified, or if cash is not reconciled regularly, the ratios you present to your board may paint an inaccurate picture. Internal controls are the policies and procedures that protect your financial data and ensure it reflects reality.

For nonprofits, several controls are essential:

• Segregation of duties. The person who approves payments should not be the same person who records them. The person who opens mail should not be the same person who makes bank deposits. Separating responsibilities reduces the risk of errors and fraud.
• Monthly bank reconciliations. Someone independent of the check-writing process should reconcile bank statements every month. Unreconciled accounts are a common source of reporting errors.
• Expense classification policies. Clear guidelines for categorizing expenses as program, administrative, or fundraising ensure consistency. Without written policies, the program expense ratio can shift based on who is coding invoices rather than actual spending patterns.
• Board review of financial statements. The board should receive and review financial statements, including ratio reports, on a regular schedule. This creates accountability and catches anomalies early.
• Annual audit or review. An independent CPA reviewing your financials provides an external check on your internal processes. For organizations receiving federal grants, a single audit may be required.

If your organization lacks formal internal controls, the ratios in your board packet may look precise but carry hidden uncertainty. Building a control framework does not require a large finance team. It requires intentional policies and consistent follow-through.

What Funders See When They Read Your Financials

Many funders require grantees to report on financial health as a condition of receiving or renewing grants. Understanding how your ratios relate to grant compliance helps your team prepare stronger applications and cleaner reports.

What Funders Typically Look For

Foundation and government funders often review:

• Program expense ratio. Funders want to see that their dollars reach the mission. A ratio below 65% may prompt questions about how grant funds will be used.
• Operating reserves. Some funders ask about reserves to assess whether your organization can sustain the project if there are payment delays. Others may view excessive reserves as a sign you do not need the grant.
• Revenue diversification. Funders prefer to support organizations that are not overly dependent on a single source. A strong revenue concentration ratio signals sustainability.
• Audit findings. Funders review your most recent audit for material weaknesses or findings related to internal controls. A clean audit builds confidence.

Where These Numbers Live on Your Form 990

Form 990, Return of Organization Exempt from Income Tax, contains the source data for most of these calculations. Part IX (Statement of Functional Expenses) breaks down spending by program, management, and fundraising. Part X (Balance Sheet) provides the asset and liability figures needed for liquidity ratios.

Your audited financial statements and the statement of functional expenses provide the rest. If your board is not regularly reviewing a dashboard that includes these ratios alongside the standard financial statements, that is a gap worth closing.

What to Have Ready When a Funder Asks

When applying for or reporting on grants, your finance team should be ready to:

• Explain any ratio that falls outside typical benchmarks and provide context.
• Provide three years of audited financials or Form 990s if requested.
• Demonstrate how grant funds will be tracked separately from general operating funds.
• Show that internal controls are in place to ensure accurate expense allocation.

Funders appreciate transparency. If your program expense ratio dipped because you invested in a new database or hired a development director, explain that. Ratios with context tell a stronger story than numbers alone.

Benchmarks Are Starting Points, Not Standards

The benchmarks listed in this article reflect general industry standards, but no single target applies to every organization. A food bank with significant donated inventory has very different liquidity needs than a healthcare nonprofit with predictable program fee revenue. A startup organization in its first two years will naturally carry a lower program expense ratio than one operating for a decade.

Context matters more than hitting a specific number. What matters most is knowing your own trend lines, understanding what is driving them, and having a plan for where you want to be in two to three years. A board that tracks ratios over time and asks the right questions will be better positioned than one that chases industry averages without understanding its own financial story.

Making These Ratios Useful in a Board Meeting

The ratios themselves are only as useful as the conversation they generate. A few practical suggestions for making them work in a board setting:

• Present ratios in context, not isolation. A current ratio of 0.9 means something different for an organization that just received a major restricted grant and has significant receivables than it does for one that has been drawing down reserves for three consecutive quarters. Always pair the number with a brief explanation.
• Track trends, not snapshots. Show three years of data where possible. A single data point is a fact. A trend is a story the board can act on.
• Set targets as a board. Rather than reacting to ratios after the fact, the board should set explicit financial policy targets for operating reserves, program expense percentage, and revenue concentration. These become the standard against which performance is measured.
• Assign follow-up. If a ratio is outside its target range, someone should be responsible for investigating why and reporting back. Ratios that are discussed but never acted on quickly lose their value.

For organizations that lack the internal capacity to produce this kind of analysis consistently, outsourced CFO services can provide board-ready financial reporting on a regular cadence, including ratio analysis, trend commentary, and variance explanations that leadership can actually use.
