You have booked your flights, secured your Machu Picchu tickets, and packed your hiking boots. But as you prepare to head to the airport, a wave of panic sets in: How do I pay for things when I get there?
Do you need to carry a wad of cash? Will your credit card work in the Andes? And most importantly, can you just use US Dollars everywhere?
Financial logistics are the most stressful part of international travel. Get it wrong, and you could be stuck at a restaurant with a card that won’t swipe or a $20 bill that no one will accept because of a tiny tear.
The currency of Cusco Peru is officially the Sol (PEN), but the reality on the ground is a hybrid economy where the US Dollar plays a massive role. However, the rules for using dollars here are stricter than anywhere else in the world.
As a travel expert who has guided thousands of US travelers through the Sacred Valley over the last 15 years, I have written this guide to save you from ATM fees, bad exchange rates, and the dreaded “rejected bill” embarrassment. Here is everything you need to know about money in the Inca Capital.
What is the Currency of Cusco Peru?
First, let’s get the terminology straight.
- Official Currency: The Sol (Plural: Soles).
- Symbol: S/
- ISO Code: PEN
You might hear locals or older guidebooks refer to it as the “Nuevo Sol.” The government officially dropped the word “Nuevo” back in 2015, but the name stuck.
The Bills and Coins
Understanding the physical cash is vital to avoid scams.
- Coins: 10, 20, and 50 centimos (cents), and 1, 2, and 5 Soles coins. Keep these! You need them for bathrooms and tips.
- Bills: 10, 20, 50, 100, and 200 Soles.
- Expert Note: Avoid the 200 Soles bill. Many small shops and taxis cannot break it. Stick to 20s and 50s.
Are US Dollars Accepted in Peru? (The Dollar Dilemma)
The most common question I get is: “Can I just use dollars?”
The answer is Yes… and No.
Are US dollars accepted in Peru? Yes, but generally only for “big ticket” tourism items.
- Where you CAN use USD: Hotels, travel agencies, expensive restaurants, and buying souvenirs at high-end alpaca stores.
- Where you CANNOT use USD: Taxis, buying water at a bodega, street food, entrance fees to small ruins, and local markets like San Pedro.
The “Pristine Bill” Rule (Crucial E-E-A-T Advice)
This is the most important tip in this entire article. In the US, we use dollar bills until they are falling apart. In Cusco, a dollar bill is treated as a piece of merchandise.
If your US bill has:
- A tiny tear (even 1mm).
- Ink marks or stamps.
- Excessive wrinkling.
- Fading.
It will be rejected. No bank, hotel, or merchant will take it. Before you leave the US, go to your bank and ask for “fresh, crisp bills.” Inspect every single one.
Cusco Exchange: Where to Get the Best Rates
So, you have your pristine dollars. Where should you swap them for Soles?
1. Casas de Cambio (Exchange Houses)
- Verdict: The Best Option.
- Location: Walk down Avenida El Sol (the main avenue near the Plaza de Armas). It is lined with legitimate exchange houses.
- Why: They offer competitive rates, are safe, and operate quickly. They usually have a sign outside showing the “Compra” (Buy) and “Venta” (Sell) rates.
2. Street Money Changers (“Cambistas”)
- Verdict: Risky.
- Location: You will see people wearing vests standing on Avenida El Sol waving calculators.
- Why: While many are legitimate, there is a risk of receiving counterfeit bills or being short-changed. For a few cents difference, it’s not worth the risk for a tourist.
3. Cusco Banks
- Verdict: Safe but Slow.
- Location: BCP, Scotiabank, and BBVA are all near the Plaza.
- Why: You will likely wait in line for 30 minutes. You also need your passport. Only do this if you are exchanging a very large amount ($1,000+).
4. The Airport (Lima or Cusco)
- Verdict: Avoid at all costs.
- Why: The spread is terrible. You will lose 10-15% of your money compared to the street rate. Only exchange $20-$40 here for immediate taxi money.
Cards vs. Cash: The Cusco Reality
In 2026, Cusco is increasingly digital, but cash is still king in the Andes.
Credit Cards
- Visa: Widely accepted everywhere.
- Mastercard: Accepted in most places.
- American Express: Rarely accepted (high merchant fees). Leave it at home or use it only at 5-star hotels.
The “Dataphone” Fee: Many smaller businesses will charge you a 5% surcharge to pay with a credit card. Always ask: “¿Cobran comisión por tarjeta?” (Do you charge a commission for card?)
ATM Withdrawals
You will find ATMs (Cajeros Automáticos) all over the historic center.
- GlobalNet (Yellow ATMs): High fees (approx. $6-$8 USD per transaction) but accept almost all cards.
- BCP / Scotiabank: Usually have lower fees.
- Decline Strategy: If your card is declined, don’t panic. Peruvian ATMs are sensitive to travel security. Unlock your card via your banking app and try a different machine.
How Much Cash to Bring to Peru?
This depends on your travel style, but here is a general rule of thumb for how much cash to bring to Peru:
- The “Base” Amount: Bring $300 – $500 USD in cash (small bills: $10s, $20s, and $50s). This acts as your emergency fund and spending money for markets.
- Daily Spending: Plan to withdraw Soles from an ATM for daily expenses (food, taxis).
- Big Expenses: Pay for hotels and tours with your credit card to save your cash reserves.
Counterfeit Money: How to Spot a Fake Sol
Counterfeit currency is an issue in Peru. When a taxi driver or vendor hands you change, take 5 seconds to check it. Do not feel rude; locals do it too.
The “Touch and Look” Test:
- Texture: Real Soles are made of cotton, not paper. They should feel slightly rough, like a US dollar. Fakes feel like printer paper.
- Watermark: Hold the bill up to the light. You should see the face of the historic figure clearly.
- The Number: Tilt the bill. The number (10, 20, 50, 100) should change color (usually purple to green).

Frequently Asked Questions (FAQ)
Here are the answers to the most common questions travelers search for regarding the what is the currency of cusco peru.
What is the best currency to take to Peru?
The best strategy is a mix. Bring US Dollars (in pristine condition) for exchange and emergency backup, but primarily use Peruvian Soles for daily transactions. Do not bring Euros, Pounds, or Australian Dollars to Cusco; the exchange rates are poor and they are harder to swap.
How much is $100 US in Peru?
Exchange rates fluctuate, but generally, the exchange rate hovers between 3.7 and 3.8 Soles per $1 USD.
- $100 USD ≈ 370 – 380 Soles. This is a significant amount of money in Cusco. It can buy a luxury dinner for two or pays for 3 days of budget hostel accommodation.
Can I use my debit card in Cusco?
Yes, but be aware of fees. Your home bank likely charges a “Foreign Transaction Fee” (1-3%) plus an “Out of Network ATM Fee” ($5). The Peruvian ATM also charges a fee. To minimize this, withdraw the maximum amount allowed (usually 400 or 700 Soles) at once rather than making small withdrawals.
Do I need cash for Machu Picchu?
Yes. While you buy your entry ticket online in advance, the bathroom at the entrance costs 2 Soles (coins only). Also, if you want to buy water or a snack at the cafe outside the gate, cash is faster and avoids potential system outages.
What is “Cusco Korkeus” and does it affect banking?
“Korkeus” means altitude/height. While the altitude (11,000 ft) affects your body, it doesn’t affect the ATMs! However, Cusco city size is walkable, so you can easily walk between banks to find the best rate—just take it slow so you don’t get winded.
Conclusion
Navigating the currency of Cusco Peru doesn’t have to be a headache. It’s all about preparation.
Remember the Golden Rules:
- Soles for the streets, Dollars for the suites.
- No rips or tears in your US bills.
- Decline the currency conversion on the credit card machine (always choose to pay in Local Currency/Soles, never in USD, to let your bank give you the better rate).
With these tips, you can stop worrying about the math and start focusing on the magic of the Andes.
