What is the average cost for table salt in a year?
If a person was following the daily recommended allowance for
sodium and he/she received all their sodium from table salt, they
would take 4000 mg (4 grams) per day, which is equivalent to 1600
mg of sodium. So table salt, sodium chloride, requirement for 1
year would be 4 grams x 365 days = 1460 grams of salt. In the
United States, salt is sold by the pound (which weighs 454 grams).
So, in a year, a person would need 3.22 pounds of salt, which costs
about 85 cents per pound, so the total in salt would be $2.73
Most of the sodium we eat is not from salt but is already in the
food, so this answer could vary greatly depending on your diet.
