How to use formula to calculate shipping charges based on order weight

[KnK Infotech]

Hello Team

 

I am using Prestashop 1.6. I would like to calculate shipping charges based on weight formula....

 

say for example...

 

I have 1 order with 3 products. Weight of individual products are as below...

 

Product 1 --> 0.25 Kg

Product 2 --> 1.25 Kg

Product 3 --> 0.25 kg.

 

As per client requirement i would like to calculate shipping cost based on below formula....

 

Shipping cost = Round_Up(Total_Order_Cost) * 14$ + 12$

                      = Round_Up(1.75 Kg) * 14$ + 12$

                      = 2 (Ex. Round of 1.75 kg) *14 + 12$

                      = 28$ + 12$ = 40 $.

 

One easy way i know is we can defined weight range & apply price in prestashop under specific carrier configuration. Prob with this solution is as my cost is based on formula (Ex. Round_Up(Total_Order_Cost) * 14$ + 12$) i need to defined each individual range (Ex. 0-1,1-2,2-3....9999-10,000).

 

Hence i would like to know do we have any other module/configuration where we can defined formula based shipping price ?

 

 

Thanks & Regards
