Champaign County, OH Insulation Payback
Champaign County, OH: what topping up your attic actually costs
Champaign County, Ohio is zone 5 under DOE's climate map (Cold), which means winters that dominate the energy bill, with cooling a minor factor. An uninsulated attic there should be built 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 2.1 years at an estimated $1,697/year saved.
That's about as fast as attic paybacks get.
Heating vs. cooling in Champaign County
The estimated savings split roughly $1,561/year heating, $136/year cooling. Out of every 100 US counties tracked here, Champaign County's savings potential beats roughly 66 of them. Within zone 5 specifically, it ranks 496th of 754 counties by estimated savings. Ohio averages $1,669/year across the counties tracked here; Champaign County comes in 2% higher.
Where these numbers come from
NOAA's Urbana Wwtp, OH US station, 2.4 miles from Champaign County, supplies the 5,839 HDD and 845 CDD this estimate runs on. Combined heating and cooling load puts Champaign County in the 65th percentile of this 3,171-county dataset. Champaign County falls in DOE's moisture regime A (humid), a detail that affects vapor-barrier recommendations more than the R-value target itself.
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 $248/year saved — roughly 9.2 years to break even. This one is a genuine toss-up, not a clear yes.

Nothing here is a guess
Every figure on this page traces to DOE/IECC climate zones and NOAA degree-day normals, documented in the methodology guide. The guide to what R-value actually means explains why R-60 is the target here specifically.
