Singapore is easy if you handle money the local way: pay in Singapore dollars, use a card for most purchases, and keep small cash for hawker stalls, markets, and small shops. For a traveler deciding what currency to use in Singapore, the rule is simple: do not rely on US dollars at the register.
The most practical setup is one no-foreign-transaction-fee Visa or Mastercard, one backup card, and about S$50–100 in small notes. For rough mental math, many US travelers treat S$10 as about $8 when the USD/SGD rate sits near 1.3, then check a live rate for larger purchases.
Using Currency In Singapore: Cards, Cash, And Change
Singapore runs on the Singapore dollar, written as SGD or S$, and everyday prices are quoted in SGD. Cards are widely accepted, but cash still matters for smaller food stalls, market purchases, and a few older businesses.
Singapore banknotes commonly seen by travelers include S$2, S$5, S$10, S$50, and S$100. Coins come in 5, 10, 20, and 50 cents, plus S$1; small coins are useful, but you do not want to carry a pocketful of change for bigger payments.
Easy rule: use a card in SGD when a terminal is offered, and use small Singapore-dollar notes when a stall or market counter feels cash-first.
Can You Pay In US Dollars In Singapore?
US dollars are not the normal payment currency in Singapore. A hotel, airport counter, or tour desk may understand USD, but shops, restaurants, taxis, attractions, and hawker stalls expect Singapore dollars or a card charged in SGD.
Do not bring a thick stack of US cash expecting to spend it directly. Bring a modest backup amount if you like, then exchange or withdraw SGD after arrival. Large US bills can be harder to change if a money changer dislikes the condition, series, or denomination.
Singapore Payment Cheat Sheet
Most Singapore spending is card-friendly, but the right payment method changes by situation. The table below gives the clean setup for the places travelers actually pay.
| Payment Situation | Use This | Why It Works |
|---|---|---|
| Hotels | Credit card charged in SGD | Hotels often need a deposit hold, and cards handle that better than cash. |
| MRT and buses | Contactless Visa or Mastercard, or a stored-value transit card | Public transport is built around tap payments, with possible bank fees on foreign cards. |
| Hawker centers | S$5, S$10, and S$20 notes | Some stalls take cards or QR payments, but cash stays the safest backup for food stalls. |
| Malls and restaurants | Card charged in SGD | Card terminals are common, and paying in SGD avoids poor terminal conversion rates. |
| Taxis and ride-hail | Card or app payment, with SGD cash backup | Card acceptance is broad, but cash helps if a terminal fails or a small surcharge applies. |
| Markets and small shops | Small SGD notes and coins | Small vendors may prefer cash and may not want to break S$100 notes. |
| Airport arrival | ATM withdrawal for a small starter amount | A small SGD withdrawal covers transport, snacks, and early cash-only moments. |
| Leftover cash | Spend small notes before departure | Changi Airport is an easy place to use remaining SGD on food or convenience buys. |
Pay By Card, But Choose SGD At The Terminal
Card payments in Singapore work well for most visitors, but the terminal should charge you in Singapore dollars. If the machine asks whether to charge in USD or SGD, choose SGD.
The USD option is dynamic currency conversion. The screen may look convenient because it shows a dollar amount you recognize, but the exchange rate is usually set by the payment processor rather than your card network. A no-foreign-transaction-fee card charged in SGD is usually the cleaner deal.
Singapore dollars are the legal answer too. The Monetary Authority of Singapore says MAS-issued notes and coins are legal tender in Singapore, and vendors can set payment terms if they tell customers before the purchase on the MAS legal tender page.
How Much Cash Should You Carry?
S$50–100 in small notes is enough for most short visits if you plan to use cards for hotels, restaurants, shopping, and transport. Carry more only if you know you will eat often at cash-first stalls or shop in markets.
A simple split works well:
- S$20–30: one food-stall meal, drinks, and small snacks.
- S$50: a comfortable day buffer for hawker meals, markets, and short taxi backup.
- S$100: a safer cushion for families, late arrivals, or travelers who dislike ATM stops.
Ask for smaller notes when exchanging money. S$50 notes are fine in many places, but S$2, S$5, S$10, and S$20 notes make small purchases smoother.
Where To Exchange Or Withdraw Singapore Dollars
ATMs are usually the simplest way to get Singapore dollars, especially if your debit card refunds ATM fees or charges a fair foreign exchange rate. Choose bank ATMs in the airport, malls, MRT-linked shopping areas, or bank branches when possible.
Money changers can be useful if you bring cash, with better rates usually found in city areas than at last-minute airport counters. Count the notes before leaving the counter, check that the rate matches the board, and avoid changing far more cash than you expect to spend.
Airport exchange counters are convenient for a starter amount, not for a full trip budget. If you land late, exchange just enough for the first evening and sort out the rest in the city.
Stay Central If You Want The Easiest Payment Setup
Central Singapore is the simplest base for a first visit because MRT stations, malls, hotels, restaurants, and cash machines sit close together. Marina Bay, City Hall, Bugis, Orchard, and Chinatown keep card-friendly spending close while still putting hawker food and small shops within easy reach.

What To Do With Leftover SGD
Small leftover Singapore dollars are easy to spend before you fly home. Use coins and small notes for coffee, convenience-store snacks, airport meals, or a transit top-up if you are still moving around the city.
Large leftover notes are less convenient. Exchange them before leaving Singapore if you do not plan to return soon, since some banks and currency desks outside Singapore may give a weaker rate or reject small leftover amounts.
The Singapore Money Setup That Works
The easiest money plan for Singapore is card-first, SGD-only, and cash-light. This setup keeps costs predictable without leaving you stuck at a cash-first stall.
- Use Singapore dollars for every in-person payment.
- Bring a Visa or Mastercard with no foreign transaction fee.
- Choose SGD, not USD, when a card terminal offers a currency choice.
- Carry S$50–100 in small notes for hawker centers, markets, taxis, and backups.
- Withdraw from ATMs or exchange a modest amount of cash after arrival.
- Spend leftover small notes before you leave Singapore.
If you follow that plan, Singapore is one of the easier places in Asia to manage travel money: cards cover the big stuff, SGD cash covers the gaps, and US dollars can stay in your wallet as backup.
