Montgomery County, KY Insulation Payback
Montgomery County attic insulation, by the numbers
Montgomery County sits in IECC climate zone 4 (Mixed-Humid) — real heating and real cooling seasons both, roughly balanced across the year. For a currently uninsulated attic, DOE and ENERGY STAR recommend building up to R-60. Going from R-2 to the recommended R-60 costs roughly $3,480 installed for a typical attic (about 1,000 sq ft), and pays for itself in about 2.3 years at an estimated $1,508/year saved. Topping up the attic pays for itself fast here.
Heating vs. cooling in Montgomery County
Split it out and it's roughly $1,349 a year on the heating side, $159 on cooling. By estimated insulation savings, Montgomery County lands in the 53th percentile nationally. Zone 4 alone covers 825 counties in this dataset, and Montgomery County comes in 161st by savings. Kentucky averages $1,385/year across the counties tracked here; Montgomery County comes in 9% higher.
Where these numbers come from
NOAA's MT STERLING, KY US station, 1.8 miles from Montgomery County, supplies the 5,046 HDD and 989 CDD this estimate runs on. Combined heating and cooling load puts Montgomery County in the 52th percentile of this 3,162-county dataset. One local detail the R-value alone won't tell you: Montgomery County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
If the attic isn't bare
Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $220/year saved — roughly 10.4 years to break even. Call this borderline rather than a clear win.

Get more than one quote before committing. Attic access and any needed air sealing move the price around, and most contractors won't take a job below roughly $600 regardless of size - worth asking upfront given Montgomery County's estimated $1,508/year on the line.
Where these figures come from
Montgomery County's R-60 target and its degree-day figures both come from named federal sources - see the methodology guide for exactly which ones. The guide to what R-value actually means explains why R-60 is the target here specifically.
