What Is the Mexican Peso?

A friendly, simple guide to the money of Mexico so you feel smart, safe, and ready to shop.

The quick answer

The Mexican peso is the money of Mexico. Its code is MXN. Its sign is $. One peso equals 100 centavos.

Meet the peso: what it is and why it matters

The peso is used to buy food, rides, gifts, and more in Mexico. It is managed by the Bank of Mexico (Banco de México). That means the peso is official, trusted, and used every day by people and stores all across the country.

Wait… why does it use the $ sign?

In Mexico, the $ sign means pesos. U.S. dollars are shown as USD or US$. So if a menu says $120, that means 120 pesos, not 120 U.S. dollars.

Bills and coins you will see

Coins (centavos): 5¢, 10¢, 20¢, 50¢
Coins (pesos): $1, $2, $5, $10, $20
Bills: $20, $50, $100, $200, $500, $1,000

Tip: Many small shops love exact change. Keep some $20, $50, and $100 bills and small coins.

How prices look in the real world

Signs and menus often show a simple $ and a number. For example, $35 for a bottle of water, or $120 for tacos. If the price seems very high for a small item, you may be reading it as dollars. Remember: in Mexico, $ means pesos.

Cards or cash? Simple rules

Big supermarkets and chain stores: cards are common.
Markets, street food, small shops: cash is king.
Always bring a little cash for tips, taxis, and restrooms.

Exchange rate basics (made easy)

The rate changes every day. Check your bank app or a trusted currency app before you buy. Ask if a store uses its own rate when you pay with a card. If you can, choose to be charged in pesos (MXN) instead of your home currency.

Safety tips that save you stress

Use ATMs inside banks or malls when possible.
Count change slowly and kindly.
Keep small bills in a handy pocket and larger bills tucked away.
