Billerica received less than its share of discretionary money on all four measures; its blended score of 9 stays between 8 and 10 under every weighting tested.

Each bar is one way of defining a fair share: Equal, the same per resident; Need, weighted toward poverty, low income and a thin tax base; Burden, by what each program pays for (road miles, bridges, pupils and so on); Effort, by what residents already pay in property tax relative to their income. The line marks 50. The score is the average of the four. Discretionary money is competitive grants and earmarks that name the town. How the index is built.

State money, FY2017–FY2026

Billerica’s town government and school districts received $384 million in formula aid and $2.7 million in competitive grants over ten years.

Each class has its own scale. Bars show dollars paid in each fiscal year.

Formula aid is gross: Chapter 70 as DESE attributes it to the town, and cherry-sheet aid before the state deducts charges such as charter tuition and transit assessments, plus other formula programs as paid. Competitive grants and earmark-account payments are Comptroller payments to the town government and its school districts (stage: paid), the same payees as the Fairness Index. Enacted earmarks and earmark payments are different things: enacted earmarks are budget clauses, counted three ways above; earmark-account payments are Comptroller payments to the town government and its school districts from accounts classified as earmarks, which can include prior-year and statewide-program money. Either can be larger. Shared revenue, pass-through contracts, transfers to state entities and unclassified payments, $28.2M in all, are not shown. Rank 1 is the highest amount per resident among 351.

Local earmarks are counted three ways: clauses that name Billerica; clauses placed in Billerica, adding organizations located here; and everything placed, adding state facilities located here. Three ways to count a local earmark.

Placed in the town: 32 clauses in ten of ten budgets; the most recent in FY2026. Every one names Billerica directly.

The burden index divides the competitive awards Billerica received from FY2017 to FY2026 by what it would have received if every program had split its money by its own measure of need: road miles for road programs, crossings for culvert grants, town-owned hazard dams for dam repair, jobs for economic development, residents for libraries. 1.0 is proportional. Billerica: 0.29. State median: 0.91. Bridges count by replacement cost and condition, not by number, and only bridges the town owns. Ranks run from 1, the most among 351.

State land eligible for PILOT is the Division of Local Services’ count of state-owned acres on which the state pays a payment in lieu of taxes; the payment follows the land’s assessed value, not its acreage, so the per-acre figure is a comparison, not the formula. The state-owned share on the land-area tile above is the MassGIS map of all state-owned open space, a wider count. New growth is the assessed value of new construction and improvements added to the tax base, summed FY2017–FY2025 and divided by 2020–24 residents; taxed at the prior year’s rates, it adds to the levy limit beyond 2.5%.

Costs and the 2½% limit

State aid covered 14.5% of Billerica’s general-fund spending in FY2025, down from 18.3% in FY2006.

FY2010: 14.9% · median town 10.0%

State aid is the gross cherry sheet as entered on the tax rate recap; spending is the town’s general-fund expenditures as filed with the Division of Local Services. Net subtracts the charges the state assesses on the same cherry sheet (charter and school-choice tuition, transit, county and other assessments), itemized from FY2010.

Billerica’s own cherry sheet carries no Chapter 70 for pupils in its regional district; the state paid $2.4 million in FY2025 Chapter 70 to the district on its behalf, outside these figures, while the town’s assessment to the district sits in its spending. For a regional member the share understates state support for school costs.

Billerica’s state aid did not keep pace with either price measure: FY2025 aid was 9.0% below its FY2006 aid grown by Boston-area consumer prices and 19.2% below grown by the government price index.

Gross state aid went from $20.4 million in FY2006 to $28.7 million in FY2025, +41.1% in dollars. Consumer prices are the Boston-area CPI-U, up 55.1% over those years; government prices are the federal price index for state and local government purchases, up 74.5%. Fiscal-year averages.

Health insurance

Nine years at 2.5% add 24.9%. Grown that way from FY2016, Billerica’s health insurance would have been $23.5 million in FY2025; it was $26.8 million, $3.24 million above the path. Its fixed costs would have been $36.2 million in FY2025; it was $41 million, $4.81 million above the path.

Fixed costs are employee benefits, retirement, insurance and similar costs in the general fund; health insurance comes from a separate DLS report. Allowed levy growth is 2.5% plus new growth, as a share of the prior year’s levy limit; a year counts as squeezed when fixed costs grew by a larger percentage.

Local earmarks against the health-insurance increase

Over the nine budgets, earmarks naming Billerica came to $867,000, 10.9% of the $7.93 million rise in its health insurance.

An earmark is a one-year appropriation; a health-insurance increase recurs in every later budget. Earmarks are counted on the three measures and are not adjusted for the January 2024 mid-year cuts or the FY2026 hold. All towns: pooled over the towns that reported health insurance in both years.

Billerica runs its own school district and also belongs to Shawsheen Valley; Billerica accounts for 36% of that district’s foundation budget.

Real figures use the CPI-U, fiscal-year average, in FY2026 dollars. The required contribution is the local share the state sets under the Chapter 70 formula; the share of income divides it per household by the town’s median household income.

Expected and actual

Billerica received $3.8 million in earmarks placed in the town and competitive grants over ten years, 36% of the $10.7 million its size, need and institutions predict.

Expected
$10.7M
Received
$3.8M

The expectation comes from a statewide model of all 351 municipalities that uses population, road miles, jobs, poverty, income, tax base, school-aid share and the presence of hospitals, colleges and nonprofits. Those factors explain about 55–60% of the differences between towns. The model leaves out many legitimate reasons a town may receive more or less, such as a single large project, so a gap is a starting point for questions, not a finding about anyone’s conduct.

Earmarks here are placed in the town, the second of three measures (enacted); competitive grants are Comptroller payments (paid). Method.

Peers

Billerica ranks 11th of 11 on earmark dollars placed in the town per resident among itself and its ten nearest peers.

Peers are the ten municipalities nearest to Billerica on population, income need and tax-base need. The best and lowest performers are the highest and lowest on earmark dollars placed in the town per resident in the wider class of 30 nearest, the second of three measures.
