You've probably looked at your screen, saw the number 375.00, and thought you were set. It's the classic math everyone does before landing in Riyadh or Jeddah. If 1 US Dollar equals 3.75 Saudi Riyals, then 100 dollars to saudi riyals must be exactly 375, right? Well, sort of. In the world of actual cash and bank transfers, that "perfect" number is often a bit of a ghost.
Honestly, the Saudi Riyal (SAR) is one of the most stable currencies you'll ever deal with because it has been pegged to the US Dollar since 1986. The Saudi Central Bank (SAMA) keeps it locked in. But "stable" doesn't mean "free." Whether you're an expat sending money home or a tourist trying to buy a decent kabsa dinner, the difference between the official rate and what hits your wallet usually comes down to who is holding your money.
The 3.75 Myth and Reality
Basically, the mid-market rate is the "real" exchange rate. It’s the one banks use to trade with each other. If you check Google or XE right now, you’ll see it sitting right at that 3.75 mark. However, unless you're a high-frequency trading firm moving millions, you aren't getting that rate.
When you convert 100 dollars to saudi riyals at a physical booth, you're more likely to walk away with 365 or 370 Riyals. Why? Commissions. Fees. The "spread." It’s how these businesses keep the lights on. Even if they scream "ZERO COMMISSION" in big neon letters, they've almost certainly baked a 3% or 4% margin into the exchange rate they’re offering you.
Where you swap matters (a lot)
- Airport Kiosks: The absolute worst. Avoid them. They know you're tired and need cash for a taxi. You might get 360 SAR for your $100.
- Local Exchange Houses: Places like Al-Rajhi or Al-Amoudi in the city centers are much better. You’ll get closer to 373 or 374 SAR.
- Hotel Front Desks: Just don't. It's a convenience fee disguised as an exchange rate.
Hidden Fees in Your Pocket
You've probably heard of Dynamic Currency Conversion (DCC). It’s that sneaky prompt on a credit card machine asking if you want to pay in "USD" or "SAR."

Always, always choose SAR.
If you choose USD, the merchant's bank decides the rate. They will charge you a "convenience" markup that can be as high as 8% or 10%. On a $100 transaction, you're basically throwing away enough money for a fancy coffee in the Financial District just for clicking the wrong button.
Digital vs. Cash: The 2026 Landscape
Saudi Arabia is moving fast toward a cashless society. With the "Digital Riyal" initiatives being discussed by SAMA, the way we handle 100 dollars to saudi riyals is shifting toward apps.
If you use a digital-first bank like STC Pay or certain international fintech cards, you often get much closer to the 3.75 peg. These platforms usually charge a flat 2% to 2.5% FX fee rather than hiding the cost in a bad exchange rate. It’s more transparent. You can actually see where every cent of your hundred bucks is going.
Practical Steps for Your Money
If you have $100 and need Riyals, don't just walk into the first bank you see.

- Check the Live Peg: Confirm SAMA’s current rate (it’s almost certainly 3.75, but check for any rare policy shifts).
- Use an ATM: Usually, withdrawing from a local Saudi bank ATM with a travel-friendly debit card gives you a better deal than a physical exchange booth.
- Say No to USD on Machines: When the waiter brings the card reader, pay in local Riyals. Your home bank's conversion is almost always cheaper than the merchant's.
- Download an App: If you're staying for more than a few days, an app like Urpay or STC Pay can save you a significant amount on domestic transactions.
At the end of the day, 100 dollars should get you roughly 375 Riyals. If you're getting anything less than 370, someone is taking a bigger cut than they probably should. Keep your eyes on the spread and stick to local currency for every swipe.
