The basic path: what happens when you send money
When you send money to someone's bank account, your bank removes the amount from your account and passes it to the recipient's bank through a payment network. The money does not travel as cash or as a single digital object. Instead, your bank creates an instruction—a record of who is sending, who is receiving, how much, and which account it goes to—and that instruction moves through a series of systems and clearing houses before the recipient's bank receives it and deposits the funds.
The speed and method depend on what you use to send it. A wire transfer moves faster than an ACH transfer. A check moves slower than either. Each method uses different networks, takes a different number of steps, and costs different amounts—or nothing at all.
The recipient does not need to do anything. Once their bank receives the instruction and confirms the account exists, the money appears in their account. They cannot reject it after it lands, though they can return it if they choose.
Key Takeaways
- ACH transfers are free or low-cost, take one to three business days, and work between most U.S. bank accounts; they are the default choice for routine payments.
- Wire transfers move the same day or next business day but cost $15 to $50 and are harder to reverse, so use them only when speed matters.
- You need the recipient's routing number and account number to send money electronically; a check requires only their mailing address.
- Money sent on a Friday or weekend does not move until the next business day, even if your bank accepts the instruction when ready.
- The recipient's bank may hold the deposit for a day or two if the amount is large or the account is new, even after the money has arrived.
ACH transfers: the standard method for most payments
ACH stands for Automated Clearing House. It is a network that moves money between bank accounts in batches, usually overnight. When you set up a payment through your bank's website or app, your bank collects it with thousands of other payments, sends them all to the ACH network at a set time each day, and the network sorts them by receiving bank and delivers them the next morning.
ACH transfers are free from most banks, or cost $1 to $3 if you use a third-party payment service. They take one to three business days. If you send on a Monday morning, the money usually lands Wednesday or Thursday. If you send on Friday, it does not move until Monday, so it lands Wednesday or Thursday of the following week.
To send an ACH transfer, you need the recipient's routing number (a nine-digit code that identifies their bank) and account number. You can find both on a check, or ask the recipient directly. You also need to know whether the account is checking or savings, though most banks accept either.
ACH transfers work between accounts at different banks, between accounts at the same bank, and from business accounts to personal accounts or the reverse. The limit varies by bank—some allow $10,000 per day, others $25,000 or more—but most people hit no limit for ordinary payments.
Wire transfers: faster but more expensive and harder to reverse
A wire transfer moves money the same business day or the next, depending on what time you send it and which bank you use. If you wire before 2 p.m. on a weekday, many banks deliver it the same day. If you wire after 2 p.m. or on a weekend, it goes out the next business day and lands the day after that.
Wire transfers cost $15 to $50 depending on your bank and whether the money stays within the U.S. or goes abroad. They are harder to reverse than ACH transfers. Once the receiving bank accepts the wire, the money is theirs, and getting it back requires the recipient to agree and initiate a return wire. For that reason, wire transfers are common for large purchases—real estate, vehicles—where speed and finality matter, but uncommon for routine bills.
You need the same information as an ACH transfer: routing number and account number. Some banks also ask for the recipient's name and address to confirm the account holder. If any detail is wrong, the wire may bounce back or land in the wrong account, and reversing it is slow and uncertain.
Checks: slowest but require only an address
A check is a written instruction to your bank to pay someone from your account. You write the recipient's name, the amount, the date, and sign it. The recipient deposits or cashes it, and your bank pays from your account.
Checks take five to ten business days to clear, depending on the distance between banks and whether the recipient deposits it quickly. If you mail a check, add three to five days for postal delivery. Checks are free to write if you have a checkbook, though some banks charge for reordered checks.
You need only the recipient's mailing address and their name. You do not need a routing number or account number. For that reason, checks are useful when you do not have the recipient's banking details, or when you want a paper record of payment.
Same-day transfers and real-time payments
Some banks now offer same-day ACH transfers or real-time payment networks like RTP (Real-Time Payments) and FedNow. These move money within minutes or hours instead of overnight. They cost the same as standard ACH transfers or slightly more, and they require the recipient's bank to participate in the network.
Same-day ACH is available from most large banks but not all smaller ones. RTP and FedNow are newer and available from a growing number of banks, but not yet universal. Check with your bank whether these options are available for your recipient's bank before you count on same-day delivery.
What information you need and where to find it
For ACH and wire transfers, you need:
- Recipient's full name (as it appears on the account)
- Recipient's routing number (nine digits; identifies the bank)
- Recipient's account number (usually 10 to 12 digits)
- Account type (checking or savings)
The recipient can find all of this on a check. The routing number is the first nine digits at the bottom left. The account number is the second set of digits, usually 10 to 12 long. If they do not have a check, they can log into their bank's app or website, call their bank, or ask their bank for a deposit slip—all of which show both numbers.
For checks, you need only the recipient's name and mailing address.
How long money actually sits in transit
The time between when you send and when the recipient sees the money is not the same as the time the money is moving. When you send an ACH transfer on Monday morning, your bank removes the money from your account when ready. But the receiving bank does not receive the instruction until Tuesday morning, and does not deposit it into the recipient's account until Tuesday afternoon. The recipient sees it Wednesday morning.
For wire transfers, the timeline is tighter. If you send before 2 p.m., your bank removes the money the same day and sends it when ready. The receiving bank usually processes it the same day or next morning, and the recipient sees it the same day or next day.
Weekends and holidays pause all movement. Money sent Friday evening does not move until Monday. Money sent the day before a holiday does not move until the day after the holiday.
After the money lands in the recipient's account, their bank may hold it for a day or two if the amount is unusually large, if the account is new, or if the receiving bank has fraud concerns. This hold is separate from the transfer time—the money has arrived, but the recipient cannot spend it yet.
Fees and limits by method
| Method | Cost | Speed | Daily Limit | Reversible |
|---|---|---|---|---|
| ACH transfer | Free to $3 | 1–3 business days | $10,000–$25,000+ (varies by bank) | Yes, within a few days |
| Wire transfer | $15–$50 | Same day or next day | Usually $10,000–$50,000+ (varies by bank) | No, after it lands |
| Check | Free | 5–10 business days | Unlimited | Yes, if not cashed |
| Same-day ACH | Free to $5 | Same business day | $25,000 (typical) | Yes, within a few days |
Limits and fees vary by bank. Call your bank or check your account settings to see what applies to you. Some banks charge more for wire transfers to other countries. Some charge a fee only if you exceed a certain number of transfers per month.
Frequently Asked Questions
What happens if I enter the wrong account number?
For ACH transfers, the receiving bank checks the account number against the name you provided. If they do not match, the transfer bounces back to your bank within one or two business days, and the money returns to your account. For wire transfers, the money may land in the wrong account, and recovering it is difficult and slow. Always double-check the account number before you send.
Can I cancel a transfer after I send it?
For ACH transfers, you can usually cancel within a few hours of sending, before your bank submits the batch to the clearing house. After that, you cannot cancel—you can only ask the receiving bank to return it, which requires their cooperation. For wire transfers, you cannot cancel after the receiving bank accepts it. Call your bank when ready if you need to stop a transfer.
Why does my bank show the money left my account but the recipient has not received it yet?
Your bank removes the money from your account as soon as you send the instruction. But the money does not reach the recipient's bank until the next business day (for ACH) or the same or next day (for wire). The recipient's bank then deposits it into their account, which may take a few more hours. The gap between when your bank debits you and when the recipient's bank credits them is normal.
Is there a limit to how much I can send?
Most banks set daily or monthly limits on ACH and wire transfers. These limits vary widely—some banks allow $10,000 per day, others $50,000 or more. Check with your bank about your specific limit. Checks have no limit. If you need to send more than your limit, you can send multiple transfers on different days, or call your bank to request a temporary increase.
What if the recipient's bank is closed when the money arrives?
The money still lands in their account. Banks process deposits 24 hours a day, even when they are closed to customers. The recipient will see the deposit the next business day when they can log in or call, but the money is in their account as soon as the receiving bank processes it.
