A Complete Guide to Functional Expenses for Nonprofits

If you’re coming to the nonprofit sector from a business background, or if you’ve just taken on more financial responsibility at your organization, functional expenses for nonprofits can feel like a foreign language at first. It doesn’t have to. Once you understand what functional expenses are, how they get allocated, and why they matter beyond the annual 990 filing, they become one of the most useful lenses you have for understanding how your organization actually spends its money, and how the outside world reads that spending.

What Are Functional Expenses for Nonprofits?

Functional expenses for nonprofits refer to the practice of categorizing every dollar your organization spends according to its purpose, not just what you bought, but what function it served. That distinction is what makes nonprofit accounting fundamentally different from the way most businesses track their spending.

The Financial Accounting Standards Board (FASB) formalized these requirements under ASU 2016-14, which established how nonprofits must identify, disclose, and document their expense allocation methodology. Understanding these nonprofit expense categories is the foundation of accurate financial reporting and the starting point for everything else in this guide.

Program Services

Program expenses for nonprofits are the costs directly tied to fulfilling your mission. If you run a workforce development nonprofit, the staff who deliver training, the materials they use, and the facility space where sessions are held are all program expenses. These are the dollars that go directly toward the work your organization exists to do.

Funders and watchdog organizations pay close attention to this number. It’s the most visible signal of whether an organization is actually putting money toward its mission, and it tends to carry the most weight when donors are evaluating where to give.

Management and General

Management and general expenses, sometimes called administrative expenses, cover the operational costs of running the organization itself. This includes executive leadership, accounting, legal, HR, and the general infrastructure that supports everything else. These costs are necessary and legitimate, but they tend to draw scrutiny when they represent a disproportionately high share of total spending.

The goal is to understand and accurately represent what they include and to make sure shared costs aren’t being dumped into this category simply because they’re hard to allocate elsewhere.

Fundraising

Fundraising expenses capture the costs associated with bringing money in, such as donor communications, events, grant writing, and development staff time. Like management expenses, these aren’t inherently bad numbers. A well-run fundraising operation often delivers significant returns on investment. But they need to be tracked separately, reported accurately, and allocated correctly when staff or resources serve more than one function.

Misclassifying fundraising costs as program expenses is one of the more common errors that surfaces during reviews and audits, and it’s the kind of mistake that erodes credibility with funders quickly.

Why This Matters Beyond the 990

Most nonprofit leaders first encounter functional expenses for nonprofits as a compliance requirement. And it’s true, completing a 990 for nonprofits requires functional expense reporting, and doing it inaccurately creates real risk at audit time. But treating it as a pure compliance exercise misses the bigger picture.

Your functional expense ratios are one of the first things sophisticated donors and institutional funders look at when evaluating your organization, and the numbers you report actively shape how it is perceived. The story your numbers tell matters. An organization that shows 90% of expenses going to programs looks very different from one showing 60%, even if both are doing meaningful work. The difference often is how costs are being allocated and documented.

When allocations are inconsistent, undocumented, or rushed through at year-end, you risk both audit exposure and a misleading picture of your financial health. Done well, functional expense tracking gives your board, your funders, and your leadership team a clearer view of where the organization’s resources are actually going.

Accurate expense tracking starts with having the right systems in place. The Charity CFO’s nonprofit accounting services help organizations build the financial infrastructure to report with confidence, from chart of accounts setup to ongoing allocation support.

How to Allocate Shared Costs

This is where functional expense allocation for nonprofits gets practical, and it’s where most organizations run into trouble. Many costs don’t belong cleanly to one category. Rent, utilities, software subscriptions, and staff salaries often support multiple functions simultaneously, and FASB requires that you allocate them across categories in a consistent way.

The method you choose matters less than your ability to apply it consistently and explain it clearly to anyone who asks.

Square Footage

Rent and utilities are among the most common shared costs nonprofits need to allocate, and square footage is the most widely accepted method for doing it. This requires knowing your space well enough to assign it purposefully and documenting that breakdown so it can be applied consistently each year and explained clearly during an audit.

Time Tracking

For personnel costs, time tracking is the most defensible allocation method. This doesn’t necessarily mean logging every minute of every day. Many organizations use periodic time studies, where staff document how they spend their time over a representative sample period, and then apply those percentages to salary allocation for the year. The key is that the methodology is documented, consistently applied, and reflects how people spend their time.

Headcount and Usage

For costs like software subscriptions, technology tools, or shared resources, headcount or usage-based allocation is often the most practical approach. If a project management platform is used by eight program staff and two administrative staff, allocating 80% to program services and 20% to management and general is a reasonable, defensible split. Executive salaries, which touch all three functional areas, are typically allocated based on a documented estimate of how the leader divides their time across programs, operations, and fundraising.

The Statement of Functional Expenses

The statement of functional expenses for nonprofits is a formal financial report that presents expenses in a matrix format, with natural expense categories like salaries, rent, and supplies on one axis, and the three functional categories on the other. It shows, at a glance, how every type of expense is distributed across program services, management and general, and fundraising, giving both internal leadership and external stakeholders a complete picture of how organizational resources are deployed.

Here’s what you need to know about who is required to produce one:

All voluntary health and welfare organizations are required to include a Statement of Functional Expenses in their audited financial statements.
Even organizations not required to produce the formal statement must still report functional expense data on their 990 for nonprofits filing.
Funders and board members increasingly expect this level of transparency regardless of legal requirement.
The statement is also a valuable internal management tool; it makes it easier to spot allocation inconsistencies and track spending patterns over time.

If your organization is working toward reporting net assets and other financial statements accurately, the Statement of Functional Expenses fits into that same discipline of rigorous, transparent financial reporting.

Building a System That Holds Up Year After Year

The organizations that struggle most with nonprofit functional expenses at audit time are usually the ones who treat allocation as a year-end exercise. Setting up your chart of accounts to capture functional data throughout the year, rather than trying to back-allocate everything in December, makes the entire process significantly more manageable. It also means that when something changes mid-year, you catch it and adjust rather than discovering it months later.

It involves establishing your allocation methodology before the fiscal year begins, training any staff who track time or code expenses, and building a simple documentation process that creates a paper trail as you go. Nonprofits that maintain clean, well-documented allocation have easier audits as well as better financial reporting overall, because their numbers reflect what’s happening in the organization rather than what was easiest to record.

Your Functional Expense Tracking Checklist

If you’re building or rebuilding your approach to functional expense tracking, here’s what a well-structured system actually looks like in practice.

Before the Year Begins:

Establish your allocation methodology and document it in writing
Set up your chart of accounts to capture functional categories from day one
Assign someone responsible for coding expenses consistently throughout the year
Train any staff who track time or submit expenses on how functional categories work

During the Year:

Conduct a mid-year review to catch allocation inconsistencies before they compound
Maintain supporting documentation for every allocation decision in case of audit review
Keep a running methodology document that explains your approach for each shared cost type

At Year-End:

Reconcile your functional expense totals before 990 preparation begins, not during it
Revisit your methodology and update it as your organization grows or staffing changes
Share a summary of functional expense ratios with your board as part of regular financial reporting

The organizations that handle audits and 990 filings with the least friction are doing these things consistently, year after year.
