Transferring Large amount vs Small Amount Which is cheaper?

Might be a stupid question but, suppose a money transferring service chanrges..for example 4% of your transfer..You transfer $50 and the receiver would only get around $47.





EDIT: There's no limit to how much they charge, always depends on the amount you're transferring and the fee keeps increasing with the amount without any particular limit.





So which is cheaper?, transferring a small amount?..or a big amount?|||the smaller amount is cheaper|||4% of 100 is less then 4% of 500 so the smaller amount is cheaper
