Can we please get help on calculating the fees of shipping to Amazon FBA centerʕ •ᴥ•ʔ

Hello:) We are a group of business students conducting a feasibility study on drop shipping bag sealers on Amazon. However, we are experiencing some problems with calculating the shipping cost to an Amazon FBA center. Since we don’t have the sellers account, it’s hard to get an exact number. Is anyone interested in helping us out? We’ll just need the numbers, no more else! Have a great day!
