Estimated payback period
2.6–3.5 years
A $2,040–$5,103 R-38 upgrade on a 2,000 sq ft Florida home typically pays for itself in 2.6–3.5 years, then keeps saving.
Estimates are for planning only and based on typical Central Florida homes and 2026 pricing for blown-in fiberglass. Your exact price depends on attic access, existing insulation condition, and whether removal is needed — confirmed free during your inspection.
Payback period is the simplest way to judge an efficiency upgrade: how long until the savings cover the cost. For attic insulation in Florida, the answer is usually just a few years — after which it keeps saving for the life of the insulation.
This calculator divides the project cost by the estimated yearly savings for your home.
What goes into this estimate
Project cost. Estimated cost to bring your attic to R-38.
Yearly savings. Estimated cooling savings for your home size and insulation gap.
Payback. Cost ÷ yearly savings = years to break even.
