Rice County, KS Insulation Payback
Rice County attic insulation, by the numbers
Rice County sits in IECC climate zone 4 (Mixed-Humid) — a genuine mix of cold winters and humid summers, with neither one dominating the bill. For a currently uninsulated attic, DOE and ENERGY STAR recommend building up to 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 $1,599 a year in heating and cooling — a payback around 2.2 years. Topping up the attic pays for itself fast here.
Where the savings come from
Split it out and it's roughly $1,344 a year on the heating side, $255 on cooling. By estimated insulation savings, Rice County lands in the 59th percentile nationally. Zone 4 alone covers 825 counties in this dataset, and Rice County comes in 52nd by savings. Kansas averages $1,594/year across the counties tracked here; Rice County comes in 0% higher.
The climate data behind this
The heating and cooling degree days behind this estimate — 5,028 HDD and 1,585 CDD (base 65°F, 1991-2020 normals) — come from STERLING, KS US, the nearest NOAA station with published normals, 9.2 miles from Rice County's center. That combined heating-and-cooling load ranks Rice County 1138th nationally by total degree days — the 64th percentile. One local detail the R-value alone won't tell you: Rice County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
If the attic isn't bare
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 $233/year saved (~9.8-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 Rice County's estimated $1,599/year on the line.
Where these figures come from
Rice 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.
