This calculator helps you estimate the shipping costs for your parcels using Canada Post's services. Input the details of your shipment below to get an estimated rate.

// Simplified Canada Post Rate Calculation Logic (Illustrative)
// Actual Canada Post rates are complex and depend on service, contract, etc.
// This example uses a basic volumetric weight calculation and zone-based pricing.
var baseRate = 5.00; // Base rate in CAD
var weightCharge = 0;
var volumeCharge = 0;
var zoneFactor = 1.0;
// Determine zone factor
switch (zone) {
case 1: zoneFactor = 1.1; break;
case 2: zoneFactor = 1.2; break;
case 3: zoneFactor = 1.3; break;
case 4: zoneFactor = 1.5; break;
case 5: zoneFactor = 1.7; break;
case 6: zoneFactor = 1.9; break;
case 7: zoneFactor = 2.2; break;
default: zoneFactor = 1.0; // Should not happen due to validation
}
// Calculate volumetric weight (kg) – often divisor is 5000 for cm
var volumetricWeight = (length * width * height) / 5000;
// Determine the greater of actual weight or volumetric weight for pricing
var effectiveWeight = Math.max(weight, volumetricWeight);
// Basic per-kg charge (simplified)
if (effectiveWeight <= 1) {
weightCharge = 8.00;
} else if (effectiveWeight 50 || width > 40 || height > 30) {
estimatedRate += 3.00;
}
resultDiv.innerHTML = "Estimated Shipping Rate: $" + estimatedRate.toFixed(2) + " CAD";
resultDiv.innerHTML += "Note: This is an estimated rate based on simplified logic. Actual Canada Post rates may vary. Factors like service type (Expedited, Xpresspost, etc.), declared value, and specific contract rates are not included.";
