Converting US Dollars to Singapore Dollars: A Complete Guide
The exchange rate between the United States Dollar (USD) and the Singapore Dollar (SGD) is one of the most widely watched currency pairs in Southeast Asia. Whether you are a business owner importing goods, an investor diversifying your portfolio, or a traveler planning a trip to the Garden City, understanding how to convert USD to SGD accurately is essential for financial planning.
This calculator allows you to perform instant conversions based on the specific exchange rate you secure from your bank or remittance service. While the interbank rate fluctuates constantly, typical rates often hover between 1.30 and 1.40 SGD for every 1 USD.
How the USD/SGD Exchange Rate Works
The currency pair tells you exactly how many Singapore Dollars you can buy for one US Dollar. For example, if the rate is 1.35, it means $100 USD converts to $135 SGD.
Unlike many other currencies that float freely, the Singapore Dollar is managed by the Monetary Authority of Singapore (MAS) against a trade-weighted basket of currencies from Singapore's major trading partners. This "managed float" system helps keep the SGD relatively stable, though it is still influenced significantly by the strength of the US Dollar.
Factors Influencing Conversion Rates
- Federal Reserve Policy: Interest rate hikes in the US typically strengthen the USD, giving you more SGD for your dollar.
- MAS Monetary Policy: Singapore uses the exchange rate (rather than interest rates) as its primary tool for price stability. If MAS appreciates the policy band to fight inflation, the SGD gets stronger (and you get fewer SGD for your USD).
- Economic Data: GDP growth, inflation reports, and employment data from both the US and Singapore cause daily fluctuations.

Why Use a Manual Rate Input?
You might notice that the rate you see on Google or financial news sites (the "mid-market rate") is different from the rate your bank offers you. Banks and money changers typically add a "spread" or margin to the exchange rate to make a profit.
By using the "Exchange Rate" field in our calculator above, you can input the actual rate quoted by your remittance provider (e.g., Wise, PayPal, or a local bank) to see exactly how much SGD you will receive, rather than a theoretical market average.
Frequently Asked Questions
Is the USD stronger than the SGD?
Yes, historically the USD has held a higher value than the SGD. One US dollar typically buys more than one Singapore dollar.
Does the exchange rate change on weekends?
Forex markets are closed on weekends. However, currency exchange services may offer you a rate on the weekend that includes a higher markup to protect themselves against market gaps when trading resumes on Monday.
