How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Number of windows = 12, Avg window size (sq ft) = 15, Hurricane category (1-5) = 2, Household size = 4 = 6 input(s) provided
  2. Calculate Total preparation cost
    Total preparation cost = windowProtectionCost + sandbagCost +
    6460 = $6,460
  3. Calculate Window protection
    Window protection = totalWindowSqFt * plywoodCostPerSqFt
    1440 = $1,440
  4. Calculate Sandbags needed
    Sandbags needed
    480 = 480
