How to calculate attic insulation cost
This calculator finds total attic insulation cost by multiplying the attic's floor area by the installed cost per square foot.
How the calculation works
Total cost = Attic area × Installed cost per sq ft.
Example
1,000 sq ft of attic area at $1.80 installed cost per sq ft: Total cost = 1,000 × 1.80 = $1,800.

Pro Tips for Attic Insulation Cost
- Installed cost per square foot varies by insulation type (blown-in, batt, spray foam) and target R-value — get quotes reflecting your specific desired insulation level.
- Attics with limited headroom or many obstructions (ductwork, wiring) may cost more per square foot to insulate than an open, easily accessible attic.
Common Attic Insulation Cost Mistakes to Avoid
- Using a generic cost-per-square-foot figure without accounting for your specific target R-value, since higher R-value insulation costs more per square foot.
