The Nonprofit 990 Field Guide: What Every Line Actually Means

You pulled up a nonprofit’s 990 filing and now you’re staring at a wall of financial terms. Total revenue, net assets, program service expenses, contributions and grants — what do these actually mean, and which ones matter?

This guide walks through the key fields on Form 990 in plain English. Bookmark it for the next time you’re reviewing a filing and can’t remember what “net assets or fund balances” means.

The income statement (Parts I and VIII)

The revenue summary appears in Part I of the 990, with the full breakdown in Part VIII (“Statement of Revenue”). These fields tell you where money came from and where it went during the tax year.

Total revenue

The organization’s total income for the year from all sources. This is the top-line number most people look at first.

Total revenue includes contributions, program service revenue, investment income, and other miscellaneous income. It does not include gains or losses from selling assets, which are reported separately.

Why it matters: This is the simplest measure of an organization’s size. A nonprofit with $500,000 in total revenue operates at a fundamentally different scale than one with $50 million.

Contributions and grants

Money the organization received as donations or grants — from individuals, foundations, corporations, or government agencies. This is the “giving” side of the income picture.

For most public charities, this is the largest revenue source. If an organization’s contributions are declining year over year, that’s a signal worth investigating.

Program service revenue

Money earned by running programs. This includes things like hospital patient revenue, tuition, ticket sales, fees for services, and government contracts for delivering services.

Some nonprofits earn most of their revenue this way. A nonprofit hospital might have $200 million in program service revenue and only $5 million in contributions. That doesn’t mean it’s not a “real” nonprofit — it means it funds itself through its mission activities.

Investment income

Interest, dividends, and other income from invested assets. For most operating nonprofits, this is a small number. For foundations with large endowments, it can be the primary income source.

Total expenses

Everything the organization spent during the year. This is the other half of the income statement.

Revenue less expenses

Total revenue minus total expenses. This is the nonprofit equivalent of profit or loss. A positive number means the organization took in more than it spent; a negative number means it drew down reserves.

A common misconception: Nonprofits are allowed to run a surplus. “Nonprofit” means the organization doesn’t distribute profits to owners or shareholders — it doesn’t mean they have to spend every dollar they receive. Healthy nonprofits typically run a modest surplus to build reserves.

The expense breakdown (Part IX)

Part IX splits total expenses into three categories. This is where you learn what the organization actually spends money on.

Program service expenses

Money spent directly on the organization’s mission activities. For a food bank, this is the cost of acquiring and distributing food. For a university, it’s instruction and research. This is the number that tells you how much of the budget goes toward the stated mission.

Management and general expenses

Overhead: administrative salaries, office rent, accounting, legal, insurance, and other costs of running the organization. Every organization has these costs.

Fundraising expenses

Money spent on raising money — events, direct mail campaigns, grant writers, development staff, and donor management systems.

The “overhead ratio” trap

People love to divide program expenses by total expenses to get a “program ratio” and judge organizations by it. An org spending 85% on programs must be better than one spending 70%, right?

Not necessarily. The overhead ratio is one of the most misused metrics in nonprofit evaluation. An organization that invests heavily in fundraising might generate far more revenue — and ultimately more program impact — than one that minimizes overhead. A startup nonprofit will naturally have a higher overhead percentage than an established one.

Use the expense breakdown to understand how an organization operates, not to score it on a single metric.

The balance sheet (Part X)

The balance sheet is a snapshot of what the organization owns and owes at the end of the tax year.

Total assets

Everything the organization owns: cash, investments, property, equipment, receivables. This is the gross value before subtracting what they owe.

Total liabilities

Everything the organization owes: mortgages, loans, accounts payable, deferred revenue.

Net assets (fund balances)

Total assets minus total liabilities. This is the nonprofit equivalent of equity — what’s left after paying all obligations.

Net assets are reported as end-of-year (EOY) and beginning-of-year (BOY). Comparing the two tells you whether the organization’s financial position improved or deteriorated during the year.

Why it matters: Net assets are a measure of financial resilience. An organization with $10 million in annual expenses and $500,000 in net assets has about 18 days of operating reserves. One with $5 million in net assets has about 6 months. The second organization can survive a funding disruption; the first cannot.

Officers and compensation (Part VII)

This section lists the organization’s officers, directors, trustees, key employees, and highest-compensated employees. For each person, the filing reports:

• Name and title
• Average hours per week devoted to the organization
• Compensation from the organization (salary and other reportable compensation)
• Other compensation (deferred compensation, nontaxable benefits)
• Compensation from related organizations (if they’re paid by an affiliated entity)

This is where you find out what the CEO makes, who sits on the board, and whether board members are compensated.

What to watch for: Officers reporting 40+ hours per week with $0 compensation are typically board members serving in a volunteer capacity. Officers with high hours and high compensation are the senior staff running the organization.

Governance (Part VI)

Part VI asks yes/or-no questions about how the organization is governed. Key disclosures include:

• Number of voting board members and how many are independent
• Whether the organization has a conflict of interest policy
• Whether the CEO’s compensation was reviewed by independent parties
• Whether the organization’s financial statements were audited

This section doesn’t contain financial data, but it tells you a lot about how seriously the organization takes governance.

Quick reference: the fields that matter most

If you’re pressed for time and just need to quickly evaluate an organization, focus on these:

Field	What it tells you
Total revenue	Organization size and scale
Revenue less expenses	Is it financially stable?
Contributions vs. program revenue	How is it funded?
Program service expenses	How much goes to the mission?
Net assets (EOY)	How much runway does it have?
Net assets (BOY vs. EOY)	Is financial position improving?
Officer compensation	Is executive pay reasonable for the org’s size?
Number of employees and volunteers	How large is the operation?
