// Logic for Calculation
// Base cost = Area * materialRate (which includes basic installation)
var baseMaterialCost = area * materialRate;
// Pitch adjustment (Difficulty and extra surface area)
var pitchCostAdjustment = (baseMaterialCost * pitchMultiplier) – baseMaterialCost;
// Removal cost
var removalCost = area * removalRate;
// Total
var totalCost = baseMaterialCost + pitchCostAdjustment + removalCost;
// Formatting currency
var formatter = new Intl.NumberFormat('en-US', {
style: 'currency',
currency: 'USD',
});
// Update UI
document.getElementById('totalDisplay').innerText = formatter.format(totalCost);
document.getElementById('materialCostDisplay').innerText = formatter.format(baseMaterialCost);
document.getElementById('pitchCostDisplay').innerText = formatter.format(pitchCostAdjustment);
document.getElementById('removalCostDisplay').innerText = formatter.format(removalCost);
