Planning a trip to Peru involves more than just booking treks to Machu Picchu or reserving tables in Lima; it requires a smart strategy for handling money. Understanding the currency in Peru is essential for avoiding high fees, getting fair exchange rates, and ensuring you can pay for everything from a bottle of water in a remote village to a fine dining experience in the capital.
This guide analyzes the key factors impacting your financial decisions, including exchange rates, the best currency to bring, and the history behind the bills in your pocket.
1. The Basics: What is the Currency in Peru?
The official currency of Peru is the Peruvian Sol.
Symbol: S/
ISO Code: PEN
Subdivision: 100 céntimos
Denominations:
- Coins: 10, 20, and 50 céntimos; 1, 2, and 5 Soles.
- Banknotes: 10, 20, 50, 100, and 200 Soles.
Traveler's Note: While you may see prices written with the symbol "S/.", the official name is simply "Sol" (plural: Soles). It is stable and widely respected in the region.
2. Exchange Rate Analysis (Late 2026 Update)
Exchange rates fluctuate daily. Below is a snapshot of conversion rates as of late September 2026, cross-checked against xe.com's live currency converter, to give you a baseline for budgeting. Always check a live converter again a day or two before you travel, since rates do shift.
| Conversion Pair | Approximate Rate (Late 2026) | Analysis |
|---|---|---|
| USD to PEN | $1 USD ≈ 3.44 PEN | The US Dollar remains the strongest foreign currency to bring. |
| PEN to GBP | 1 PEN ≈ £0.22 GBP | UK travelers will find their pound stretches reasonably well, though less than in previous decades. |
| PEN to NGN | 1 PEN ≈ 386 NGN | For Nigerian travelers, the conversion rate is significant. 1,000 Peru currency to Naira is approximately 386,000 NGN. |
Practical Examples
How much is $1000 in Peru currency? If you bring $1,000 USD to Peru, you can expect to receive approximately S/ 3,440 (Peruvian Soles), depending on the "buy" rate of the exchange house.
Currency in Peru to GBP: Conversely, if you have leftover Soles at the end of your trip, S/ 100 would convert to roughly £22 GBP.
How much is $100 US in Peru?
As of late 2026, $100 USD is equivalent to approximately 340 to 345 Peruvian Soles (PEN).
The "Real" Exchange: While the official rate is around 3.44 PEN to $1 USD, money changers (casas de cambio) will typically give you a slightly lower "buy" rate.
Important Caveat: You will only receive this full value if your $100 bill is in pristine condition. If the bill has even a tiny tear (as small as 2mm), a stamp, or ink writing, it may be rejected entirely or exchanged at a significantly reduced rate (sometimes losing 10-20% of its value).
3. What is the Best Currency to Take to Peru?
The best strategy is a two-currency approach:
- Bring US Dollars (USD): This is the best foreign currency to carry physically. It is universally recognized and easy to exchange. Bring high-denomination bills ($50s and $100s) for the best exchange rates, but ensure they are "uncirculated" or look brand new.
- Withdraw Peruvian Soles (PEN): For daily spending, rely on withdrawing Soles directly from ATMs (GlobalNet, BCP, or Scotiabank) in major cities. This ensures you have the local cash needed for taxis, markets, and tips.
- Avoid: Bringing GBP, AUD, or CAD to exchange outside of Lima or Cusco, as rates for these are poor and acceptance is low.
Option A: Bringing US Dollars (The Gold Standard)
Pros: widely accepted for high-ticket items (hotels, train tickets, tour packages). Easy to exchange anywhere in the country.
Cons: You generally cannot use USD for small daily purchases (taxis, street food, water) without receiving a poor exchange rate.
The "Clean Bill" Rule: This is critical. Peruvian merchants and banks will strictly reject any USD bills with rips, ink marks, excessive wrinkles, or water damage. Your bills must look crisp and new.
Option B: Relying on ATMs (The Convenient Route)
Pros: You get the local currency immediately without carrying large amounts of cash.
Cons: Fees can add up. You will likely face a local ATM fee (approx. S/ 20 to 30) plus your home bank's international fee.
Tradeoff: You pay for convenience. To minimize costs, withdraw the maximum amount allowed (often S/ 400 or S/ 700) rather than making frequent small withdrawals.
Option C: Bringing Other Currencies (GBP, EUR, CAD, AUD)
Challenge: Exchanging currency in Peru to GBP or CAD is possible in Lima and Cusco but very difficult in smaller towns like Aguas Calientes or Ollantaytambo. You will often suffer from a "double exchange" rate (Home Currency to USD to PEN) spread if you exchange these directly at poor rates.
4. Where to Exchange Money: A Risk vs. Reward Analysis
Deciding where to exchange your money involves balancing safety against the value of the rate.
| Location | Exchange Rate | Safety | Verdict |
|---|---|---|---|
| Casas de Cambio (Exchange Houses) | Best | High | Recommended. Look for physical offices with posted rates. They are faster than banks and offer better rates than the street. |
| Banks | Moderate/Poor | Very High | Safe, but slow lines and lower rates. Good for withdrawing huge sums, bad for exchanging $100 bills. |
| Street Exchangers ("Cambistas") | Good | Low | Risky. They wear colored vests and offer competitive rates, but swapping cash on a sidewalk exposes you to theft and a higher risk of counterfeit bills. |
| Airports | Worst | High | Avoid. Only exchange what you need for a taxi or immediate transport. |
5. History: Old Currency in Peru
You may hear stories about the Inti or the Sol de Oro. Understanding this history helps you avoid confusion if you encounter old notes.
The Inti (1985 to 1991): Due to hyperinflation in the late 80s, the Inti lost its value completely. It was replaced by the Nuevo Sol (New Sol) in 1991 at a rate of 1,000,000 Intis to 1 Nuevo Sol.
Current Status: Old currency like the Inti is worthless as legal tender. It is sold only as a souvenir. If someone tries to give you a bill that says "Inti," do not accept it as payment.
6. Strategic Tips for Travelers
- Break Your Bills: A S/ 100 note is considered "big money." Small vendors, taxi drivers, and rural shops often cannot make change for it. Always try to break large bills at supermarkets or restaurants so you have S/ 10 and S/ 20 notes for daily use.
- Fake Currency: Counterfeit coins (especially S/ 2 and S/ 5) are an issue. Real coins have distinct, sharp ridges on the edge and a clear watermark on bills. If a coin feels unusually light or smooth, check it carefully.
- Notify Your Bank: Before traveling, ensure your credit and debit cards are authorized for use in Peru to prevent them from being blocked for "suspicious activity."

FAQs: Currency in Peru
How much is $100 US in Peru?
As of late 2026, $100 USD is equivalent to approximately 340 to 345 Peruvian Soles (PEN).
What is the best currency to take to Peru?
The best strategy is a two-currency approach: bring US Dollars (USD) for high-ticket items and easy exchange, then withdraw Peruvian Soles (PEN) from ATMs for daily spending on taxis, markets, and tips. Avoid bringing GBP, AUD, or CAD, since rates for these are poor outside Lima or Cusco.
Is US currency accepted in Peru?
Yes, but with strict limitations.
Where it works: You can use US Dollars to pay for big-ticket tourist expenses like hotels, tour packages, train tickets (PeruRail/IncaRail), and sometimes at high-end restaurants in Lima or Cusco.
Where it fails: You cannot use US Dollars for daily conveniences like taxis, buying water at a corner store (bodega), street food, or entry fees to smaller ruins. Local vendors will either refuse the dollars or offer you a terrible exchange rate (e.g., valuing $1 USD at only 2.80 Soles instead of 3.44).
The Rule: Always pay in Soles for anything costing less than $20 USD.
What can you buy with 1 Sol?
One Sol (S/ 1.00) is a small amount (roughly $0.29 USD), but it still has purchasing power in local markets (Mercados).
- Food: 4 to 5 fresh bread rolls (pan frances) from a local bakery.
- Snacks: A small packet of cookies (like "Casino" or "Margarita") or a single piece of fruit (a banana or tangerine) from a street vendor.
- Transport: In smaller provincial towns (outside Lima), S/ 1.00 might cover a short mototaxi ride, though S/ 2.00 is becoming the new standard.
- Services: Using a clean, public restroom at a bus terminal or market usually costs S/ 0.50 to S/ 1.00.
