Mexico Currency & Money Guide: Exchange, Cards, and Tips

Mexico uses the Mexican peso (MXN), written as $ or MX$, and 1 SGD was worth approximately 14.6 MXN in late October 2026; live rates change, so check your card issuer or currency app before exchanging. Carry pesos for markets, taxis, small restaurants, tips, and rural areas, while using a no-foreign-transaction-fee card for hotels, larger restaurants, and supermarkets. Withdraw from bank-attached ATMs, always choose to pay in MXN, and budget 10–15% for restaurant service. The Mexico destination guide is useful for planning routes and practical details. Hello’s app can track expenses in pesos and Singapore dollars, automatically convert exchange rates, scan receipts, and split shared costs with travel companions.

The Mexican peso is Mexico’s official currency, and travellers should use pesos rather than assuming US dollars will be accepted at the best rate. As a late-October 2026 reference, 1 SGD was approximately 14.6 MXN, while 1 MXN was about S$0.0685, according to Financial Times market data; your bank’s rate will include its own spread or fee. Exchange only a small amount at the airport for transport and your first meal, because airport counters commonly offer less competitive rates. Banks, established exchange houses called casas de cambio, and card withdrawals are generally better options. Count your cash before leaving the counter and compare the final amount, not just the advertised rate. Keep small notes and coins for colectivos, public toilets, street food, cafés, and tips. Mexican banknotes include denominations such as 20, 50, 100, 200, 500, and 1,000 pesos, although smaller businesses may struggle to change large notes. Hello’s multi-currency expense tracker automatically converts MXN spending into SGD, making it easier to see the real cost of each meal, tour, or taxi.

The safest Mexico money strategy is to combine a small cash reserve with withdrawals from reputable bank ATMs attached to branches, rather than exchanging large amounts or relying on isolated machines. Major Mexican banks include BBVA, Banorte, Santander, and Banamex. Reported ATM fees commonly range from 30–100 MXN per withdrawal, before any charge from your Singapore bank, so withdrawing a sensible amount less frequently can reduce fixed costs. Fees and limits vary by machine; read every screen before confirming. If the ATM offers to convert the withdrawal into Singapore dollars, US dollars, or another home currency, decline the conversion and choose MXN. Dynamic currency conversion can produce a noticeably worse rate; some travel guidance estimates that selecting pesos may save roughly 3–8%. Use ATMs during daylight, inspect the card slot, cover your PIN, and keep the cash discreet. Avoid standalone machines in convenience stores, nightlife areas, and busy tourist strips when a branch ATM is available. If a card is retained, do not accept help from strangers; contact the bank using its official number and freeze the card if necessary.

Cards work well in Mexico’s hotels, supermarkets, chain restaurants, tour operators, airports, and resort areas, but cash remains essential for markets, family-run eateries, local transport, beach vendors, and smaller towns. Visa and Mastercard have broad acceptance, while American Express can be less consistently accepted. Contactless card payments are increasingly common in major cities and tourist zones, although terminals may still require a PIN or physical card. Always check the amount on the terminal before tapping, and select MXN rather than accepting a converted Singapore-dollar amount. Carry a second card separately in case one is blocked. Digital payment habits vary locally: bank transfers and QR-based payments are used in Mexico, but visitors should not assume that WeChat Pay, PayPay, or other foreign wallets will work everywhere. Confirm acceptance before ordering, especially at independent businesses. A card-only plan can fail during internet outages or in smaller destinations, so keep roughly 500–1,000 MXN in mixed denominations for a day of local travel. If you need mobile data for banking apps, maps, or digital receipts, an eSIM from Hello can be activated before departure so you arrive connected.

Mexico tipping is customary rather than strictly mandatory, and 10–15% is a practical restaurant guideline when service is not already included; check the bill carefully before adding anything. In tourist restaurants, 15% is often considered standard for good service, while excellent service may justify more. Never pay an unexplained ‘service charge’ twice. Typical everyday amounts include 10–20 MXN for supermarket baggers or petrol-station attendants, 20–50 MXN per bag for hotel porters, and around 50–100 MXN per day for housekeeping, left daily rather than at the end. For guides and drivers, consider 50–100 MXN per traveller for a shorter activity or more for a full-day private experience, depending on service and group size. Tipping expectations differ between Mexico City, beach resorts, and smaller communities, so observe local practice. Keep 10-, 20-, and 50-peso notes specifically for gratuities. If a card terminal requests a tip, verify that the percentage and final total are correct before approving. Hello’s expense-splitting feature can record the tip separately and automatically convert each person’s share when friends pay in different currencies.

Travellers can reduce Mexico costs by paying in pesos, comparing transport options, and avoiding rushed exchange decisions in airports, hotel lobbies, and tourist strips. A casual local meal may cost about 80–180 MXN in 2026, while a mid-range restaurant meal can be roughly 250–600 MXN per person before drinks and tip; resort zones and popular neighbourhoods may cost considerably more. Common money scams include inflated exchange rates, card-terminal overcharging, fake taxi pricing, and ATM skimming. Choose official taxis or reputable ride services, agree on fares before entering a street taxi, and review the receipt or terminal total. At cash machines, use a bank branch, cover the keypad, and reject dynamic currency conversion. For savings, eat at busy local markets, refill a reusable bottle where safe, use public transport when practical, and book popular tours directly through established operators. Keep an emergency reserve separate from your everyday wallet. Hello’s AI receipt scanning, voice expense entry, bank-statement import, and automatic categorisation help reveal where your budget is going; a daily MXN limit can prevent small purchases from quietly exceeding your plan.

The simplest answer is to carry pesos for everyday spending, use cards selectively, and confirm every exchange or payment in MXN before approving it. These answers cover the questions most travellers ask before visiting Mexico, from whether Singapore dollars can be exchanged to how much cash is practical for a day. Can I use Singapore dollars in Mexico? Usually not directly. Exchange SGD through a bank or reputable casa de cambio, or withdraw pesos from a Mexican bank ATM. Should I bring US dollars? They may be accepted in some resorts and border areas, but merchants often set their own conversion rate; pesos are usually more transparent. How much cash should I carry? Around 500–1,000 MXN for a normal day is a useful starting point, adjusted for tours, transport, and destination. Is tipping expected? Yes, especially in restaurants, hotels, tours, and personal services; 10–15% is a common restaurant range when no service charge appears. Are ATMs safe? Bank-attached machines used during branch hours are preferable. What if a card terminal asks for currency? Choose MXN and decline conversion into SGD. How can I track spending with friends? Hello supports multi-currency expense splitting, automatic conversion, receipt scanning, and budget tracking in the Hello app for iOS and Android.
