How to Use a Hurricane Shutter Cost Calculator (And What It Can and Cannot Tell You)

Online hurricane shutter cost calculators — including the one on this site — are useful for one specific purpose: getting a ballpark number to start a budget conversation. Understanding what inputs drive the estimate, and where the estimate will diverge from your actual quote, makes the tool genuinely useful rather than misleading.

How the AHS Cost Calculator Works

Our cost calculator asks you to specify the shutter type and the total square footage of openings you want to protect. It then multiplies your input by our current base rate for that shutter type and returns a preliminary estimated range.

The inputs are: shutter type (panels, accordion, roll-down, screens, Bahama, colonial), estimated total square footage of all openings, and optionally the number of openings. The output is a dollar range representing the low and high of typical installations at those parameters.

The Per-Square-Foot Math: How to Estimate Your Own Square Footage

Measure the width and height of each opening you want to protect in inches, convert to feet, and multiply to get square footage. Add all openings together for your total. Example for a typical 3-bedroom home:

A 3-bedroom home with 10 standard windows, 2 sliders, and 2 entry doors totals approximately 280–360 sq ft. Multiply by your shutter type rate: 320 sq ft × $34/sq ft (accordion) = $10,880 estimated.

What the Calculator Gets Right

The calculator accurately reflects our base installed rates for each shutter type. If you input a reasonable square footage and select a shutter type, the output will be within 15–25% of most final quotes. For budgeting purposes — deciding whether accordion shutters or storm panels make sense for your budget — that accuracy is more than sufficient.

Where the Calculator Diverges From Your Actual Quote

Minimum charges

Very small openings have minimum fabrication charges. A window that is 6 sq ft technically costs $204 at $34/sq ft, but the minimum for that opening may be $350. The calculator does not account for minimums, which means it may underestimate costs on homes with many small windows.

Substrate complexity

Mounting into concrete block, brick, or tile adds labor cost. The calculator assumes standard wood-frame mounting. If your home is concrete block construction — common in coastal SC — your actual quote will be somewhat higher than the calculator suggests.

Design pressure upgrades

Oceanfront properties in high-velocity hurricane zones require upgraded panel profiles and hardware specifications. The calculator uses standard coastal rates. Homes on or very close to the water may require heavier specifications that add 5–15% to the base rate.

Mixed shutter types

Many homeowners use accordion shutters for windows and doors and hurricane screens for a large lanai opening. The calculator handles single shutter types. For mixed installations, run the calculator separately for each type and add the results.

How to Use the Calculator Most Effectively

• Run the calculator for two or three shutter types to understand the cost range across options before meeting with us
• Add 10–15% to the calculator output as a contingency for minimum charges and substrate conditions
• Use it to determine whether your preferred shutter type fits your budget before investing time in an estimate appointment
• Do not use it to compare quotes from different companies — different companies have different base rates and different definitions of what is included in “installed”
