Taney County, MO Insulation Payback
Taney County attic insulation, by the numbers
DOE classifies Taney County as climate zone 4, mixed-humid — real heating and real cooling seasons both, roughly balanced across the year. Its recommended attic R-value for bare joists is R-60. Topping up a typical 1,000-square-foot attic from bare joists (R-2) to R-60 runs an estimated $3,480, and saves about $1,317 a year in heating and cooling — a payback around 2.6 years. Topping up the attic pays for itself fast here.
The breakdown behind the number
Split it out and it's roughly $1,069 a year on the heating side, $248 on cooling. By estimated insulation savings, Taney County lands in the 40th percentile nationally. Zone 4 alone covers 825 counties in this dataset, and Taney County comes in 552nd by savings. Missouri averages $1,534/year across the counties tracked here; Taney County comes in 14% lower.
Taney County's actual weather, not a national average
NOAA's OZARK BEACH, MO US station, 4 miles from Taney County, supplies the 3,997 HDD and 1,544 CDD this estimate runs on. Combined heating and cooling load puts Taney County in the 41th percentile of this 3,162-county dataset. One local detail the R-value alone won't tell you: Taney County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
Already have some insulation?
A shallower starting point changes the math: with R-11 already down, only the gap to R-49 needs filling, at roughly $2,280 for an estimated $192/year saved (~11.9-year payback). 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 Taney County's estimated $1,317/year on the line.
Where these figures come from
Taney 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.
