Calculate mail cost

To calculate the cost of mailing an item, you'll need to consider the following factors:

1. Weight: The weight of the item being mailed.
2. Dimensions: The length, width, and height of the item being mailed.
3. Destination: The zip code or postal code of the recipient.
4. Service: The type of mail service used (e.g., First Class, Priority Mail, Parcel Post).
5. Package type: The type of package being used (e.g., envelope, box, tube).

Here's a general formula to calculate the cost of mailing an item:

First Class Mail (letters, flats, and small packages):

• Weight-based pricing:
  • Up to 1 oz: $0.55
  • 1 oz to 2 oz: $0.65
  • 2 oz to 3 oz: $0.75
  • 3 oz to 3.5 oz: $0.85
  • 3.5 oz to 4 oz: $0.95
  • Each additional ounce: $0.15
• Dimensional pricing (for larger items):
  • Length + (2 x width + 2 x height) ≤ 13 inches: $1.00
  • Length + (2 x width + 2 x height) > 13 inches: $1.50

Priority Mail (small packages and envelopes):

• Weight-based pricing:
  • Up to 1 lb: $7.50
  • 1 lb to 2 lbs: $8.50
  • 2 lbs to 3 lbs: $9.50
  • 3 lbs to 4 lbs: $10.50
  • Each additional pound: $1.50
• Flat rate pricing (for small packages and envelopes):
  • Small Flat Rate Box: $7.50
  • Medium Flat Rate Box: $14.35
  • Large Flat Rate Box: $19.95

Parcel Post (larger packages):

• Weight-based pricing:
  • Up to 1 lb: $6.35
  • 1 lb to 2 lbs: $7.35
  • 2 lbs to 3 lbs: $8.35
  • 3 lbs to 4 lbs: $9.35
  • Each additional pound: $1.35

Additional fees:

• Insurance: $2.50 to $5.00 (depending on the value of the item)
• Signature confirmation: $2.95 to $3.95 (depending on the service level)
• Delivery confirmation: $0.50 to $1.50 (depending on the service level)

To calculate the total cost of mailing an item, add up the costs of the weight, dimensions, and any additional fees.

Example:

• You want to mail a 1-pound package with dimensions 12 inches x 8 inches x 4 inches to a destination with a zip code of 12345.
• You choose Priority Mail with insurance and signature confirmation.
• The total cost would be:
  • Weight-based pricing: $8.50 (1 lb)
  • Insurance: $3.00 (for a value of $100)
  • Signature confirmation: $3.95
  • Total: $15.45
