This page does not publish an entry allowance for United States passport holders, and that is deliberate. The source cached for this cluster is written for a different nationality, and an allowance does not transfer between passports. Ask the Salvadoran consulate responsible for where you live, close to your travel date, and get the answer for the passport you will actually be carrying.
What follows is the structure of the rules, which is worth understanding whatever your nationality, because the structure is where people come unstuck.
⚠ There are two clocks and they are not the same clock
The cited source records both, a few paragraphs apart, and they answer different questions.
The first is national. A visitor may come to El Salvador for tourism or business for up to 180 days without a visa, and may extend that stay by contacting the General Directorate of Migration and Immigration.
The second is regional. Under the CA-4 Agreement a traveler may move between El Salvador, Guatemala and Nicaragua for up to 90 days without a visa. The agreement also includes Honduras, though the cited source notes that British nationals need a visa to visit it. And the mechanism is the part that catches people: the 90 day period starts when you enter any of these countries and does not restart when you cross a border between them. You still go through immigration checks each time. If you are expelled from one, you are excluded from the others.
So a month in Guatemala followed by a month in Nicaragua leaves you a month, not three. Count from your first entry stamp in the region, not from the Salvadoran one. If your itinerary is El Salvador only, the 180 days is the number that matters. The moment it becomes a Central America trip, the 90 days is.
What to have with you
Carry a passport with plenty of validity left, and check the specific validity rule for your nationality before you book, because it varies. Keep a photocopy of the passport and of your entry stamp somewhere separate from the original, and leave the original somewhere secure once you have arrived. That is the cited advice and it is sensible in a country where the most likely problem is petty theft rather than anything official.
Money you must declare
Cash or traveler's checks worth 10,000 US dollars or more must be declared on arrival. This is a declaration, not a limit, and the only cost of doing it is a few minutes.
⚠ A transit fee that applies to some passports and not others
The cited source records that Indian nationals, and nationals of any African country, passing through El Salvador must pay a fee of 1,130 US dollars. It is a large amount and it applies in transit, which is exactly the situation in which someone is least likely to have checked. If your routing puts you through San Salvador and your passport falls into either group, confirm the current position with the airline and with a Salvadoran consulate before you buy the ticket, not at the airport.
Vaccination requirements are about where you have been
The CDC records that the yellow fever vaccine is not recommended for travel to El Salvador, and is not required for direct travel from the United States. The requirement is narrow and concerns your route rather than your destination: a certificate is required of travelers aged one year and over arriving from a country with risk of yellow fever transmission, and that category includes an airport transit or layover of more than 12 hours in such a country.
Read that threshold carefully if you are connecting through South America. Twelve hours is shorter than the equivalent threshold in several neighboring countries, and a long connection can put you inside a requirement you did not plan for. Decide your route before your vaccinations and ask a travel health professional early.
Entry is only the paperwork. The travel safety guide in this cluster covers the state of exception, which is the thing most worth understanding before you arrive.
