What this calculator does

• Estimates your total project cost based on size (width × height), window type, frame material, glass type, wind zone, and quantity.
• Shows a clear cost breakdown: base window cost, installation cost per window, quantity, materials, and labor.
• Lets you use default pricing or enter your own per-window cost (C) if you have supplier pricing.

How the pricing formula works

The calculator uses the industry‑standard formula:

• TC = (N × C) + I + L
• TC: Total cost of installing impact windows
• N: Number of windows
• C: Cost per window (window + install)
• I: Additional installation materials
• L: Labor cost

How C (cost per window) is calculated by default

• Base window cost = Area × Base rate (by window type) × Frame multiplier × Glass multiplier × Wind-zone multiplier
• Cost per window (C) = Base window cost + Installation cost per window

Default reference rates

• For a 1″ × 1″ window:
  • Single Hung: base $0.24 ⇒ C ≈ $175.25 (with $175.01 install)
  • Double Hung: base $0.25 ⇒ C ≈ $175.26
  • Casement: base $0.52 ⇒ C ≈ $175.53
  • Sliding: base $0.66 ⇒ C ≈ $175.67
  • Fixed/Picture: base $0.52 ⇒ C ≈ $175.53

Note: You can also choose to enter a custom C if you already know your per‑window price.

Step-by-step: How to use the Hurricane impact windows cost calculator

1. Enter window size

• Width (inches) and Height (inches). The calculator shows area in sq in and sq ft automatically.

2. Choose your window type

• Single Hung, Double Hung, Casement, Sliding, or Fixed/Picture.

3. Select frame material and glass type

• Frame: Aluminum, Vinyl, Fiberglass, or Wood Clad.
• Glass: Limited Impact, Tempered, Double Pane, or Triple Pane.
• These apply multipliers to the base price.

4. Pick your wind zone rating

• Basic (up to 110 mph), High (up to 130 mph), or Missile Impact (150+ mph).
• Higher wind ratings increase the base cost due to stronger requirements.

5. Set quantity (N)

• Use the slider or number input (1–50). The subtotal updates automatically.

6. Add materials (I) and labor (L)

• Enter any additional installation materials and your labor cost.

7. Review the breakdown

• Check Base Window Cost, Install Cost per Window, Cost per Window (C), Subtotal (N × C), then total (TC).

8. Optional advanced settings

• Enter a custom C (per-window price) if you already have one from a supplier.
• Adjust the install cost per window or set a minimum base charge if needed.

Two quick examples

• Example A: Using your own C
  • N = 1, C = $50, I = $100, L = $200
  • TC = (1 × 50) + 100 + 200 = $350
• Example B: Using default calculated C for a 1″ × 1″ Single Hung
  • Area = 1 in × 1 in = 1 sq in
  • Base rate (Single Hung) = $0.24/in²
  • Multipliers (Aluminum, Limited Impact, Basic wind) = 1.00
  • Base window cost = 1 × 0.24 × 1.00 = $0.24
  • Install cost per window = $175.01
  • C = 0.24 + 175.01 = $175.25
  • With I = $100 and L = $200, N = 1
  • TC = (1 × 175.25) + 100 + 200 = $475.25

What affects cost the most?

• Size: Larger area increases base cost.
• Window type: Sliding and casement often have higher base rates than hung.
• Glass type: Double/Triple Pane and impact-rated glass increase cost.
• Frame material: Vinyl, fiberglass, and wood clad typically cost more than aluminum.
• Wind zone: High-velocity and missile-impact zones increase the base window cost.

Tips to get an accurate estimate

• Measure width and height in inches; round up to the nearest quarter inch if needed.
• Pick the wind zone that matches your code requirements (check local AHJ if unsure).
• Include realistic labor and materials (I and L) based on site conditions.
• Use the custom C option when you have a per-window quote from a specific brand.

FAQ

• Are these prices exact?
• They’re estimates. Final quotes may vary by brand, permits, disposal, trim, structural work, and site access.

• Do taxes, permits, or delivery fees appear here?
  • Not by default. You can include them under Materials (I) or add separate line items before finalizing a proposal.

• Can I use this for commercial projects?
• Yes, but commercial specs may require different glass, frames, and engineering—adjust multipliers, I, and L accordingly.

• What if I only know a per-window price?
  • Enable the custom C option and enter your per-window price. The calculator will compute TC with TC = (N × C) + I + L.

Simple variable cheat sheet

• N: number of windows
• C: cost per window (window + install)
• I: additional materials (sealants, flashing, anchors, etc.)
• L: labor for installation
• TC: total cost = (N × C) + I + L
