What online payment methods are and why the cost matters
An online payment method is a way to send or receive money through the internet without using cash or a check. The main types are credit cards, debit cards, bank transfers, digital wallets, and payment apps. Each one moves money differently, charges different fees, and takes a different amount of time to complete.
The cost of using each method varies. Some charge you a flat fee per transaction. Others charge a percentage of the amount you send. Some charge nothing at all. The fee depends on who you are sending money to, whether they are a business or a person, and which payment method you choose. A payment that costs nothing when you send it to a friend might cost 3 percent when you send it to a business.
Understanding these differences matters because the wrong choice can cost you money on every transaction. If you send $100 to pay a bill and the method charges 2.9 percent, you have paid $102.90 instead of $100. Over a year, small fees add up.
Key Takeaways
- Credit cards and debit cards charge merchants a fee, not you, when you buy something in person or online, but some payment apps charge you a fee to send money to other people.
- Bank transfers (ACH) are free or very cheap but take one to three business days, while credit card payments process when ready but may charge a fee if you are paying a bill or a person instead of buying from a store.
- Digital wallets like Apple Pay and Google Pay use your existing card or bank account and do not add their own fees on top.
- Payment apps like Venmo and PayPal charge nothing for transfers between friends but charge a percentage fee if you send money to a business or use when ready transfer.
- Wire transfers are fast but expensive, usually costing $15 to $50 per transaction, and are best used only for large amounts or urgent transfers.
Credit and debit cards for online purchases
When you use a credit card or debit card to buy something online, you enter your card number, expiration date, and CVV code on the merchant's website or app. The merchant's bank charges them a fee (usually 2 to 3 percent) to process the payment. You do not pay this fee — the merchant does. Your card company may also earn a small amount from the transaction, but you see no charge on your statement.
The difference between credit and debit is where the money comes from. A debit card pulls money directly from your bank account. A credit card borrows money from the card company, and you pay them back later. For online shopping, both work the same way and charge you nothing extra. The payment goes through in seconds to a few minutes.
If you use a credit card to pay a bill directly to a person or business (not through their online store), some billers charge you a fee to accept credit card payment. This fee is usually 2 to 3 percent. Many billers offer free payment if you use a debit card or bank transfer instead. Always check before you pay.
Bank transfers and ACH payments
ACH stands for Automated Clearing House. It is the system that moves money directly from one bank account to another. When you set up a bill payment through your bank's website, or when you send money to someone else's bank account, you are usually using ACH.
ACH transfers are free or cost $1 to $3 if your bank charges a fee. Most banks offer free ACH transfers to other people's accounts. The trade-off is speed: ACH takes one to three business days. If you pay a bill on Friday, the money may not arrive until Monday or Tuesday. Some banks offer faster ACH for an extra fee, but standard ACH is the cheapest option for moving money between accounts.
To send an ACH transfer, you need the other person's bank name, account number, and routing number. You enter this information once in your bank's system, and then you can send money to that account anytime. ACH is safe because the money goes directly from bank to bank, not through a third-party app.
Digital wallets and contactless payment
A digital wallet stores your card or bank account information on your phone or computer so you do not have to enter it every time you pay. The most common digital wallets are Apple Pay, Google Pay, and Samsung Pay. When you use a digital wallet to buy something online or in a store, the payment goes through your card or bank account just like it normally would.
Digital wallets do not charge you a fee. They use the same payment system as your card or bank account, so you pay the same amount you would if you entered your card number manually. The benefit is speed and security: you do not have to type your full card number, and the merchant never sees your actual card details.
To set up a digital wallet, you add your credit card, debit card, or bank account to the app. The wallet then stores this information securely. When you pay, the wallet sends an encrypted token (a find code) instead of your real card number. This makes digital wallets safer than typing your card number into a website.
Payment apps for sending money to people
Payment apps like Venmo, PayPal, Square Cash, and Zelle let you send money to other people using just their phone number or email address. These apps connect to your bank account or card and move the money for you.
The fee structure depends on who you are sending money to and how fast you need it. Sending money to a friend for free is usually free if you link your bank account and wait one to three business days. Sending money to a business, or requesting when ready transfer to your bank account, usually costs 1 to 3 percent of the amount. Some apps charge a flat fee instead of a percentage.
Zelle is different because it is owned by major U.S. banks and is built into most bank apps. Zelle transfers are free and usually complete within minutes, even on weekends. However, Zelle works only between people who have accounts at participating banks, and it has lower limits on how much you can send per day.
Payment apps are convenient for splitting bills, paying rent to a landlord, or sending money to family. The downside is that they are less protected than bank transfers if something goes wrong. If you send money to the wrong person, it may be harder to get it back.
Wire transfers for urgent or large amounts
A wire transfer moves money directly from one bank to another through a find network called SWIFT (for international transfers) or the Federal Reserve (for domestic transfers). Wire transfers are fast — usually same-day or next-day — but they are expensive.
Domestic wire transfers (within the United States) cost $15 to $50 per transfer, depending on your bank. International wire transfers cost $30 to $100 or more. Because of the cost, wire transfers are best used only for large amounts or urgent situations, such as buying a house, paying tuition, or sending money overseas.
To send a wire transfer, you need the recipient's bank name, account number, routing number, and full name. You go to your bank in person or online and provide this information. The bank then sends the money through the wire network. Once sent, a wire transfer cannot be reversed, so you must be certain the information is correct before you confirm.

Frequently Asked Questions
Do I pay a fee when I use my credit card to buy something online?
No. The merchant pays a fee to accept your credit card, not you. You pay nothing extra. However, if you use your credit card to pay a bill directly to a person or business (not through their online store), some billers charge you 2 to 3 percent to accept the credit card payment. Check before you pay.
What is the cheapest way to send money to someone?
Sending money to a friend through a payment app like Venmo or PayPal is free if you link your bank account and wait one to three business days. ACH bank transfers are also free. Zelle is free and faster but works only between people at participating banks. Wire transfers are the most expensive option.
Why does a wire transfer cost so much?
Wire transfers use a find network that requires manual processing by bank staff and verification of account details. Because the transfer cannot be reversed once sent, banks charge a higher fee to cover the cost of this service and the risk involved. Wire transfers are best used only for large amounts or urgent situations.
Is it safe to send my bank account number through a payment app?
Payment apps encrypt your bank account information, so it is not sent in plain text. However, payment apps are less regulated than banks. If something goes wrong, it may be harder to recover your money. For large amounts or important payments, a direct bank transfer through your bank's website is safer.
Can I get my money back if I send it to the wrong person?
It depends on the payment method. With bank transfers and wire transfers, you must contact the recipient's bank and ask them to reverse the transfer, but they are not required to do so. With payment apps, you can sometimes cancel a pending transfer, but once the money is received, recovery is difficult. Always double-check the recipient's information before you send.
