gross vs. net – Gross refers to the total and net refers to the part of
the total that really matters. For example, net income for a business is
the profit after all expenses, overhead, taxes and interest payments are
deducted from the gross income. Similarly, gross weight refers to the total
weight of the goods and the container and packaging. On the other hand,
net weight refers to only the weight of the goods in question. When it
comes to earned income: gross income is before taxes and deductions, and
net income is after taxes and other deductions.
