How to Wire Money: Domestic and International Transfers Explained

Sending money across town — or across the globe — used to mean standing in line at a bank with paperwork and a prayer. Today, wire transfers make it possible to move thousands of dollars in hours. But “wire transfer” is one of those financial terms people use without fully understanding the mechanics, the costs, or the risks. Whether you’re paying a contractor overseas, buying a home, or helping a family member abroad, this guide breaks down exactly how domestic and international wire transfers work — and how to send one without getting burned.

What Is a Wire Transfer?

A wire transfer is an electronic method of moving funds directly from one bank account to another. Unlike writing a check or swiping a card, a wire transfer moves money through a secure network — no physical currency changes hands, and there’s no middleman holding your funds in transit.

Wire Transfers vs. ACH Transfers

Many people confuse wire transfers with ACH (Automated Clearing House) transfers. They’re related but different:

  • Wire transfers move money in real time (or same business day), are generally irrevocable, and cost more — typically $15–$50 per transaction.
  • ACH transfers batch-process overnight, often take 1–3 business days, are reversible in some cases, and are usually free or very low cost.

Use a wire when speed and certainty matter — such as closing on a house or paying a large overseas invoice. Use ACH for routine payroll, bill pay, or small recurring transfers.

Domestic vs. International Wires

The core difference is routing. Domestic wires travel through the Fedwire Funds Service or the CHIPS network within the United States. International wires use SWIFT — the Society for Worldwide Interbank Financial Telecommunication — a global messaging system that routes funds through correspondent banks across borders.

When Should You Use a Wire Transfer?

  • Real estate closings where same-day funds are required
  • Large business-to-business payments
  • Paying overseas vendors, suppliers, or contractors
  • Sending large sums to family abroad
  • Any transaction where speed and finality are critical

How to Send a Domestic Wire Transfer

Sending money within the United States is straightforward once you understand what information you need. Here’s the process step by step.

What Information You’ll Need

Before you initiate a domestic wire, gather the following from the recipient:

  • Recipient’s full legal name — must match the account holder name exactly
  • Recipient’s bank name and address
  • ABA routing number — the 9-digit number that identifies the receiving bank
  • Recipient’s account number
  • Wire purpose or memo — some banks require a brief explanation

Initiating a Wire at Your Bank

Most banks let you initiate domestic wires online, through a mobile app, by phone, or in person. Log into your online banking portal and look for “Wire Transfer” or “Send Money.” You’ll fill out a form with the recipient details above, enter the amount, and confirm. Many banks cap online wire limits — if you’re sending over $10,000 or $25,000, you may need to call or visit a branch.

Timing and Cut-Off Times

Domestic wires submitted before the bank’s daily cut-off (often 3:00–5:00 PM Eastern) typically arrive the same business day. Wires sent after the cut-off or on weekends are processed the next business day. Always confirm the cut-off time with your bank, especially for time-sensitive transactions like real estate closings.

Domestic Wire Costs

  • Outgoing domestic wires: typically $15–$35
  • Incoming domestic wires: often free, but some banks charge $10–$15
  • Online wires are sometimes cheaper than branch-initiated wires

How to Send an International Wire Transfer

International wire transfers follow a similar process but involve additional complexity — more information required, more fees, and longer delivery times. Understanding the SWIFT system helps you avoid surprises.

What Information You’ll Need for International Wires

In addition to the basics above, international wires require:

  • SWIFT/BIC code — an 8–11 character code identifying the recipient’s bank internationally (e.g., BOFAUS3N for Bank of America)
  • IBAN — International Bank Account Number, required for transfers to Europe, the Middle East, and many other regions
  • Recipient’s country and full address
  • Purpose of payment — required in many countries for regulatory compliance
  • Intermediary bank details — sometimes needed when your bank and the recipient’s bank don’t have a direct relationship

How SWIFT Routing Works

When you send an international wire, your bank sends a SWIFT message to a correspondent or intermediary bank, which then forwards the funds to the recipient’s local bank. Each intermediary bank in the chain may deduct a fee — known as a correspondent bank fee — before passing the money along. This is why your recipient sometimes gets slightly less than you sent.

Exchange Rates and Currency Conversion

If you’re sending money in a foreign currency, your bank applies an exchange rate — and it almost never matches the mid-market rate you see on Google. Banks typically mark up the exchange rate by 2–5% as additional profit. For large amounts, consider comparing your bank’s rate against services like Wise (formerly TransferWise) or OFX, which often offer rates much closer to the mid-market rate.

International Wire Fees and Timing

  • Outgoing international wires: typically $25–$50 at major U.S. banks
  • Correspondent bank fees: $10–$25 per intermediary (sometimes deducted from the amount)
  • Delivery time: 1–5 business days depending on the destination country
  • Some countries with strong U.S. banking relationships (UK, Canada, Western Europe) settle faster

Wire Transfer Fees, Timing, and Safety Tips

Wire transfers are fast and powerful — but they’re also a favorite target for scammers. Understanding fees, timing, and security protocols can save you a lot of money and heartache.

Comparing Wire Transfer Costs Across Banks

Fees vary significantly by institution. Here’s a general comparison:

  • Big banks (Chase, Wells Fargo, Bank of America): $25–$45 outgoing domestic; $40–$50 outgoing international
  • Online banks (Ally, Marcus): Often lower fees, sometimes $0 for incoming
  • Credit unions: Usually lower than big banks, sometimes $10–$20 domestic
  • Wire transfer services (Wise, OFX, Western Union): Often cheaper for international, especially with better exchange rates

Wire Transfer Safety Rules

Wire transfers are irrevocable — once sent, the money is gone. Fraudsters know this and exploit it. Follow these non-negotiable rules:

  • Always verify wire instructions by phone using a number you know is legitimate — never the number in an email
  • Never wire money to someone you haven’t met in person if you have any doubts
  • Be skeptical of last-minute wire instruction changes — a classic sign of Business Email Compromise (BEC) fraud
  • Never wire money as payment for unexpected prizes, tax debts, or “emergency” situations
  • Confirm receipt with the recipient after sending

What to Do If a Wire Transfer Goes Wrong

Act immediately. Contact your bank within the same business day if possible — although rare, banks can sometimes recall a wire if the receiving bank hasn’t yet credited the account. File a complaint with the FBI’s Internet Crime Complaint Center (IC3) if fraud is suspected. The faster you act, the better your chances.

Conclusion

Wire transfers remain one of the safest and most reliable ways to move large sums of money quickly — whether across the country or across the world. The key is preparation: gather accurate recipient information, understand the fees involved, and never skip the verification step. For domestic transfers, your bank’s online portal makes the process simple. For international transfers, compare exchange rates and factor in correspondent bank fees before hitting send. And above all, treat wire instructions with the same caution you’d give to handing over a bag of cash — because that’s essentially what you’re doing.
