Statement of Functional Expenses: Allocation Methods Explained

Every nonprofit produces financial statements that show what was spent. The Statement of Functional Expenses shows how it was spent — whether resources went toward programs, administrative overhead, or fundraising. For auditors, grantors, and watchdog organizations, this is often the most scrutinized financial document a nonprofit produces.

The Statement of Functional Expenses is a matrix that shows how each type of expense (salaries, rent, supplies) is distributed across functional categories (program services, management and general, fundraising) — revealing how an organization spends its resources in pursuit of its mission.

This article explains the statement's structure, the allocation methodologies used to build it, and the most common audit findings.

Why the Statement of Functional Expenses Matters

The functional expense distribution is the basis for overhead ratio calculations. Charity watchdog organizations, major donors, and institutional funders all use the ratio of program expenses to total expenses as a quick proxy for organizational efficiency. This ratio is calculated directly from the Statement of Functional Expenses.

Beyond the external audience, the statement has important internal uses. It shows organizational leadership where resources are actually going — a question that is surprisingly difficult to answer from a natural-expense-only income statement.

Under FASB ASC 958 as amended by ASU 2016-14, all nonprofits must present expenses by both natural and functional classification. This can be done through a standalone Statement of Functional Expenses, within the Statement of Activities, or in the notes to the financial statements. Most organizations with an independent audit produce a standalone statement.

The Matrix Format

The statement is organized as a matrix:

• Rows represent natural expense categories — what was purchased: salaries and benefits, rent and occupancy, professional fees, supplies, travel, communications, depreciation, interest, and other.
• Columns represent functional categories — what it was used for:
  • Program services (further broken out by program if the organization has multiple programs)
  • Management and general
  • Fundraising
  • Total

Each cell contains the dollar amount of that natural expense type allocated to that functional category. The row totals equal total expenses by natural category. The column totals equal total expenses by function. Both should reconcile to the Statement of Activities.

The Three Functional Categories

Program Services

Program services are the activities that directly fulfill the organization's stated mission. For a homeless services organization, this includes shelter operations, case management, and job placement programs. For an arts organization, it includes performances, education programs, and artist residencies.

Organizations with multiple programs should break out program expenses by program within the program services column. This requires an additional sub-dimension in the allocation — not just "is this program?" but "which program?"

Management and General

Management and general expenses are the costs of running the organization — not delivering programs. This includes executive leadership time spent on governance and management (not programs), finance and accounting, legal and compliance, board relations, information technology supporting the whole organization, and general office expenses.

The critical distinction: a portion of the executive director's salary belongs in management and general. The portion they spend on program oversight, direct service, or fundraising belongs in the other categories. This allocation is based on actual time, not on job title.

Fundraising

Fundraising expenses are the costs of soliciting charitable contributions. This includes development staff salaries, donor events, direct mail appeals, grant writing (for charitable contributions, not government contracts), donor database costs, and a share of communications costs related to donor cultivation.

Note: grant writing costs for government contracts are typically classified as program or management and general, not fundraising. The distinction is between soliciting charitable contributions (fundraising) and obtaining contracts for services (program development).

Allocation Methodologies

Shared costs — salaries, rent, utilities, insurance, and technology that benefit multiple functional areas — must be allocated using a reasonable, documented, and consistently applied methodology. Here are the most common approaches:

Salaries: Time Studies

Staff salaries are typically the largest expense line and the most important to allocate correctly. The standard methodology is a time study: staff members track their time by functional category over a representative period (two to four weeks is typical), and the resulting percentages are applied to their salaries throughout the year.

Time studies should be conducted annually and should capture actual activities rather than estimated activities. An executive director who assumes they spend 80% of their time on programs but actually spends half their time on board relations and administrative management will produce an overstated program ratio if the study is not conducted rigorously.

For small organizations where time studies are administratively burdensome, written job descriptions that document the expected time allocation by function may be acceptable — but must be reviewed for reasonableness by the auditor.

Rent and Occupancy: Square Footage

Space costs are typically allocated based on the proportion of square footage used by each functional area. Measure the floor space dedicated to program activities, management functions, and fundraising operations, then allocate rent, utilities, and building maintenance proportionally.

If space is shared across functions throughout the day (a conference room used by all departments), the space is allocated to each function in proportion to total headcount or total labor cost.

Technology: Usage or Headcount

IT costs for systems used across the organization can be allocated based on headcount, active users, or a fixed ratio based on system purpose. A donor database is primarily a fundraising tool; its cost allocates mostly to fundraising with a portion to management and general. A program management database allocates primarily to program.

Other Shared Costs

• Insurance: Allocate based on relative value of assets insured or headcount
• Communications and postage: Split based on actual use (program mailings versus donor appeals)
• Professional fees: Allocate to the function served (audit fees to management and general; grant writing to fundraising or program)

---

Documentation Requirements for Auditors

The allocation methodology is auditable. Your auditors will ask for:

Written allocation policy: A board-approved document that describes the methodology used for each category of shared expense, the basis for selection, and how the methodology is updated.

Time study documentation: The actual time study worksheets or records, showing dates, participating staff, activities recorded, and resulting percentages.

Floor plan or space measurement records: Supporting documentation for square footage allocations.

Consistency: The same methodology applied in the current year as in prior years, unless a change is documented and disclosed.

Changing allocation methodologies without disclosure is a common audit finding. If your organization's program ratio changes materially from one year to the next due to a methodology change rather than actual expense changes, auditors expect a note explaining the change.

Sample Statement (Partial)

Natural Expense	Program A	Program B	Mgmt & General	Fundraising	Total
Salaries and benefits	$380,000	$210,000	$145,000	$65,000	$800,000
Rent and occupancy	$52,500	$17,500	$17,500	$12,500	$100,000
Professional fees	$15,000	$0	$45,000	$20,000	$80,000
Supplies	$18,000	$12,000	$5,000	$2,000	$37,000
Depreciation	$25,000	$8,000	$12,000	$3,000	$48,000
Total	$490,500	$247,500	$224,500	$102,500	$1,065,000

In this example, program services account for $738,000 of $1,065,000 in total expenses — a 69.3% program ratio. Management and general is 21.1% and fundraising is 9.6%.

The Efficiency Gap: Recalculating Allocations Every Month

For most nonprofit Controllers, building the Statement of Functional Expenses is the most time-consuming month-end task. Allocation percentages must be applied to each natural expense category. If salaries change (a new hire, a termination, a raise), the allocation must be recalculated. If rent changes, the occupancy allocation updates. Each recalculation is an opportunity for formula error, version mismatch, or a number that does not reconcile to the general ledger.

The sherbertOSOS allocation engine stores allocation rules — percentage splits by expense category, basis, and functional area — and executes them automatically each accounting period. When actual expenses change, allocations update accordingly. The Statement of Functional Expenses is a direct output of the ledger, not a spreadsheet assembled after the fact.

Frequently Asked Questions

Is the Statement of Functional Expenses required?

Under ASC 958, all nonprofits must present expenses by both natural and functional classification. This can be accomplished in a standalone Statement of Functional Expenses, within the Statement of Activities, or in the notes. For organizations with independent audits, a standalone statement is standard practice.

What are the three functional categories?

Program services (mission-delivery activities), management and general (administrative overhead), and fundraising (costs of soliciting charitable contributions). Organizations with multiple programs typically break out program services by individual program within the statement.

What is the best way to allocate shared staff salaries?

Time studies are the gold standard. Have staff record actual time by functional category for two to four weeks, then apply the resulting percentages to their annual salaries. Time studies should be conducted annually and documented for auditor review.

How do I allocate rent across functional categories?

Use square footage as the allocation basis. Measure the floor space dedicated to each functional area and allocate rent, utilities, and building maintenance proportionally. Shared spaces are allocated based on headcount or total labor cost.

The Bottom Line

The Statement of Functional Expenses is not just a compliance requirement. It is the most transparent representation of how your organization deploys its resources — and it is the document that donors, grantors, and watchdog organizations use to evaluate your efficiency. Getting the allocation methodologies right, documenting them thoroughly, and producing the statement without a spreadsheet assembly project every month are all achievable with the right accounting infrastructure.
