Fund balance in governmental accounting is the difference between what a governmental fund owns and what it owes, measured using only short-term financial resources like cash and receivables rather than long-term assets like buildings or roads. The Governmental Accounting Standards Board standardized how governments report this figure through Statement No. 54, which took effect for fiscal years beginning after June 15, 2010, and sorts fund balance into five categories based on how tightly each dollar is constrained.1Governmental Accounting Standards Board. Summary of Statement No. 54 – Fund Balance Reporting and Governmental Fund Type Definitions Those classifications, and the math behind them, tell taxpayers, bond buyers, and elected officials whether a government can pay its bills today and absorb surprises tomorrow.
The Math Behind the Number
The formula comes from GASB Statement No. 63, which set the balance sheet presentation for governmental funds:
Fund Balance = (Assets + Deferred Outflows of Resources) − (Liabilities + Deferred Inflows of Resources)2Governmental Accounting Standards Board. Statement No. 63 – Financial Reporting of Deferred Outflows of Resources, Deferred Inflows of Resources, and Net Position
Assets here means current financial resources: cash, investments, receivables, and other items that convert to cash in the near term. Capital assets like buildings and infrastructure do not appear on a governmental fund balance sheet. Deferred outflows are resources consumed now that belong to a future reporting period; deferred inflows are the reverse. The calculation produces a snapshot as of a single date, typically the last day of the fiscal year, and the resulting total is then broken out across five classifications.
Governments publish these figures in their Annual Comprehensive Financial Report, or ACFR. The document was called the Comprehensive Annual Financial Report until GASB Statement No. 98 changed the name in late 2021.3Governmental Accounting Standards Board.

The Five GASB 54 Classifications
GASB 54 replaced the older “reserved and unreserved” labels with a hierarchy that runs from the most constrained dollars to the least. Each classification answers a single question: how free is the government to redirect these resources?
Nonspendable
Nonspendable fund balance covers resources that are either not in a form you can spend or that must be kept intact by law or contract. Inventory sitting in a warehouse, prepaid insurance, and the principal of a permanent endowment fund all fall here.1Governmental Accounting Standards Board. Summary of Statement No. 54 – Fund Balance Reporting and Governmental Fund Type Definitions These amounts appear on the balance sheet as assets, but nobody can write a check against them.
Restricted
Restricted fund balance includes amounts that can only be spent for purposes dictated by parties outside the government itself. Those outside constraints come from three sources: constitutional provisions, external resource providers like grantors or creditors, and enabling legislation.1Governmental Accounting Standards Board. Summary of Statement No. 54 – Fund Balance Reporting and Governmental Fund Type Definitions A federal highway grant that can only pay for road construction is restricted. So are property tax revenues that a state constitution dedicates to education. The government receiving those dollars has no discretion over their use.
Committed
Committed fund balance results from a government imposing constraints on itself through the highest level of its own decision-making authority. For a city, that usually means the city council passes a resolution or ordinance; for a county, the board of supervisors takes a comparable formal vote.1Governmental Accounting Standards Board. Summary of Statement No. 54 – Fund Balance Reporting and Governmental Fund Type Definitions The formal action must happen before the end of the fiscal year, though the exact dollar amount can be pinned down afterward.4Governmental Accounting Standards Board. Statement No. 54 – Fund Balance Reporting and Governmental Fund Type Definitions Once committed, the funds can only be redirected through the same formal process that locked them in.
Assigned
Assigned fund balance reflects an intent to use resources for a particular purpose, without the formal vote required for committed funds. A finance director, budget officer, or other official with delegated authority can create this designation.1Governmental Accounting Standards Board. Summary of Statement No. 54 – Fund Balance Reporting and Governmental Fund Type Definitions Assigned amounts carry less weight than committed ones because they can be changed without a vote of the governing body. It is an internal earmark rather than a binding commitment.
Unassigned
Unassigned fund balance is the leftover. In the general fund, it captures every spendable dollar not already classified as nonspendable, restricted, committed, or assigned. This is the money a government has the most discretion over, and it is the primary cushion against unexpected costs. In any other governmental fund, unassigned can only appear as a negative number, which signals that spending on a restricted or committed purpose has outpaced the resources set aside for it.1Governmental Accounting Standards Board. Summary of Statement No. 54 – Fund Balance Reporting and Governmental Fund Type Definitions Most financial analysts treat the unassigned balance as the clearest indicator of a government’s fiscal flexibility.
How Much Should a Government Hold?
GASB 54 tells governments how to classify fund balance but says nothing about how much to keep. That guidance comes from the Government Finance Officers Association, which recommends that general-purpose governments maintain unrestricted fund balance in the general fund of no less than two months of regular operating revenues or expenditures, whichever is more predictable in the government’s circumstances.5Government Finance Officers Association. Fund Balance Guidelines for the General Fund Two months translates to roughly 16.7 percent of annual operating figures.
That number is a floor, not a target. Governments with volatile revenue streams, concentrated tax bases, or exposure to natural disasters should hold more. A city that depends heavily on sales tax revenue will see sharper swings during a recession than one funded primarily by property taxes, and its reserve needs reflect that. Jurisdictions vulnerable to earthquakes, wildfires, or flooding face cleanup costs that can dwarf normal budget contingencies.
How Fund Balance Affects Credit Ratings
Rating agencies treat fund balance as a direct input to creditworthiness scores. Moody’s calculates an “available fund balance ratio” by adding unassigned, assigned, and committed governmental fund balances to net current assets from business-type activities, then dividing by total revenue. Nonspendable and restricted amounts are excluded from the numerator because the government cannot deploy them freely. The resulting percentage maps to a scorecard tier:6Moody’s. US Cities and Counties Rating Methodology
- Aaa range: 25 to 35 percent
- Aa range: 15 to 25 percent
- A range: 5 to 15 percent
- Baa range: 0 to 5 percent
- Below investment grade: negative ratios
A government can carry a large total fund balance and still score poorly if most of those dollars are locked up. The split between restricted and unrestricted amounts directly influences borrowing costs, which is where the GASB 54 categories carry real financial weight.
Fund Balance Is Not Retained Earnings
Readers coming from a private-sector background sometimes try to map fund balance onto retained earnings, but the two concepts measure different things. Retained earnings represent the cumulative profit a corporation has reinvested rather than distributed to shareholders. That calculation spans all time periods and uses full accrual accounting, which tracks long-term assets, depreciation, and long-term liabilities.
Governmental fund balance uses modified accrual accounting, which focuses on current financial resources: what can be collected and spent in the near term. A city hall building worth tens of millions does not appear on a governmental fund balance sheet, and the annual depreciation on that building never reduces fund balance. Government-wide statements capture those long-term figures separately, but the fund-level reports deliberately ignore them to keep the focus on short-term liquidity and legal compliance.7Governmental Accounting Standards Board. Summary of Statement No. 34 – Basic Financial Statements and Management’s Discussion and Analysis for State and Local Governments The philosophical difference matters too. A corporation aims to grow retained earnings for shareholders; a government aims to hold fund balance at a level that keeps services running and borrowing costs low.
