Flat Rate:

Total Rate = (Weight Input) x (Exceeding Cost After Min Weight)

Example 1: 

Actual weight (User Input) = 11 kg.

Min. Weight Declared = 5 kg.

Max. Weight Declared = 10kg.

Rate = $20.00

Exceed Weight Rate after min. weight = $2.50

Total Rate = 20  + ( (11 – 5 )  X 2.50 )

Total Rate = $35.00

---

Example 2: 

Actual weight (User Input) = 5 kg.

Min. Weight Declared = 1 kg.

Max. Weight Declared = 5kg.

Rate = $20.00

Exceed Weight Rate after min. weight = $0.00

Total Rate = 20  + ( (5 – 1 )  X 0 )

Total Rate = $20.00

---

Example 3: 

Actual weight (User Input) = 6 kg.

Min. Weight Declared = 5kg.

Max. Weight Declared = 10kg.

Rate = $20.00

Exceed Weight Rate after min. weight = $2.50

Total Rate = 20  + ( (6 – 5 )  X 2.50 )

Total Rate = $22.50

 

Cost per Weight:

Total Rate = (Weight Input) x (Exceeding Cost After Min Weight)

Example 1: 

Actual weight (User Input) = 11 kg.

Min. Weight Declared = 5 kg.

Max. Weight Declared = 10kg.

Rate (Cost per Weight) = $2.00

No result: Actual weight not between Min. and Max. Weight

---

Example 2: 

Actual weight (User Input) = 11 kg.

Min. Weight Declared = 5 kg.

Max. Weight Declared = 20kg.

Rate (Cost per Weight) = $2.00

Total Rate = 11 X 2

Total Rate = $22.00

 

Cost per Qty:

Total Rate = (Qty) x (Flat rate/Cost Per Weight)

Example 1: 

Qty (User Input) = 5 pcs

Min. Weight Declared = 5 kg.

Max. Weight Declared = 20kg.

Rate (Cost per Weight) = $2.00

Total Rate = 5 X 2

Total Rate = $10.00

Example 2: 

Qty (User Input) = 19 pcs

Min. Weight Declared = 5 kg.

Max. Weight Declared = 20kg.

Rate (Cost per Weight) = $2.00

Total Rate = 19 X 2

Total Rate = $38.00
