Case: Calculating Real Ratios from Cumberland County

If you only read one thing Three of this chapter’s actual ratios, calculated from Cumberland County, Maine’s real 2024 numbers, land right where the chapter’s own benchmarks say they should, and one reveals a genuine gap worth knowing about.

Builds on Topics 4 and 5 This calculates the actual formulas from those topics using a real Maine county’s real reported figures, not a hypothetical example.

Why This Matters

Reading a ratio formula is one thing. Calculating it from a real government’s actual numbers, and seeing it land inside or outside a real benchmark, is what makes this chapter’s content usable rather than theoretical.

What’s Actually Going On

Revenues over expenditures: Cumberland’s General Fund reported total revenues of $70,718,895 against total expenditures of $69,247,734 for 2024. That’s a ratio of 1.02, just above the 1.0 benchmark the chapter considers average, a modest, healthy operating surplus, not a red flag in either direction.

Fund balance as a percentage of operating revenues: Cumberland’s total General Fund balance of $8,750,861 divided by its total revenues comes to 12.4%. Topic 4 flagged 10-25% as generally adequate, and Cumberland’s real number lands right inside that range, neither dangerously thin nor unusually large.

Business-type activity self-sufficiency: Cumberland’s Cross Insurance Arena, an Enterprise Fund covered in FM8, reported $17,846,521 in charges for services against $22,727,012 in total expenses for 2024. That’s only 78.5% self-sufficiency, meaning roughly $4.9 million in costs were covered by something other than the arena’s own charges, most likely transfers, the same pattern FM8.5 described as worth flagging when it recurs.

How This Applies

Two of these three ratios landed comfortably inside healthy benchmarks. The third, the arena’s self-sufficiency gap, is exactly the kind of real finding this chapter’s ratio analysis is built to surface, not evidence of mismanagement by itself, but a genuine number worth watching over time, the same way FM8 already flagged it as a pattern worth tracking.
