The cost of food depends on what you are buying and where you buy it. I buy fresh vegetables and fruit from the local outdoor markets and it is very cheap compared to the U.S. I get a large bag of tomatoes (10-12) for $1.00, a bunch of onions also $1.00, a head of Cabbage .75 and a large bag of mangos $1.00. Most of these are grown locally year-round. I shop for my meats, canned goods and cereals at Selectos, Wall-Mart and PriceSmart(a store like Sam’s Club or Costco). There prices are about the same or a little more than in the U.S., Elizabeth and I spend about $60.00 – $70.00 a week for food and that is because I eat American style if you eat Salvadorian style it would be a lot less.
The cost of utilities is about the same as in the U.S., we have a 3040 sq. ft. home with everything you would find in an American home except heat and our electric bill averages $200.00 a month. Our Internet service costs $20.00 a month and Dish TV costs $12.00 a month.
There is no tax to speak of unless you have a business or are very wealthy. There is no tax on money made outside of the country. There is no land tax unless you own very large amounts of land. We have not paid any tax/fee other then the yearly cost to register our car ($35.00). There are fees when registering and deeding property which are one time fees.
For Medical care here you have Cigna, Allianz, Bupa and Aetna to name a few that offer expat insurance in El Salvador, I think they are very reasonable. You can create a plan that fits your needs. They have very good hospitals and doctors (many English speaking) in San Salvador A visit to a specialist costs $25-$35 a visit, blood tests usually run $10-$20 and X-rays run $15-$25.
El Salvador is not for everyone, but if you are tired of the snow and cold winters or you will not be able to live well on what you have for retirement in the United States then I would suggest you check out El Salvador. I enjoy it here very much.
