What credit card processing costs are
What are credit card processing fees?
- Credit card processing fees are what a business pays each time it accepts a card. They bundle three parts: interchange paid to the card-issuing bank, assessments paid to the card network, and the processor's markup. The total is roughly 1.5% to 3.5% of each transaction, depending on the processor and the pricing structure.
What is the average processing fee for a credit card?
- The average Visa and Mastercard credit rate was 2.36% in 2025. The average Visa and Mastercard processing cost is approximately 2.35%. Your own average depends on card mix, how cards are entered, and your pricing plan, so the effective rate calculator on this site is the fastest way to find yours.
What is a normal transaction fee?
- A normal card transaction fee is a percentage of the sale plus a small fixed amount. A flat-rate plan example is 2.6% plus 10 cents, and an interchange-plus markup example is 0.4% plus 8 cents added on top of interchange. In-person transactions typically cost about 1.8% to 2.6% plus $0.08.
Why do credit card companies charge merchants?
- Card companies charge merchants because every card payment passes through several paid parties. The issuing bank collects interchange, the network such as Visa or Mastercard collects assessments, and the processor charges a markup for moving the money. 80 to 90 percent of what a business pays to accept cards is interchange, which is the same at every processor.
Why are credit card processing fees so high?
- Fees feel high because most of the cost is interchange that merchants cannot negotiate, and the markup on top often stays fixed once a business signs with one processor. US merchants paid a record $198.25 billion in card fees in 2025. Without ongoing competition on the markup, there is little pressure for a single processor to lower it.
Which credit cards charge merchants the most?
- Rewards and other premium credit cards generally cost merchants more than basic cards, and regulated debit costs the least. One industry guide's interchange schedule (rates effective 24 October 2026) runs from 1.18% + $0.05 for supermarket credit up to 3.15% + $0.10 for consumer credit that qualifies for no specific program, while regulated debit carries 0.05% + $0.21. Check your statement's card-type breakdown to see your mix.
What is an effective processing rate?
- Your effective processing rate is total processing fees divided by total card sales for the same period. If you paid $2,900 in fees on $100,000 of card sales, your effective rate is 2.9%. It captures every fee on the statement, including monthly and per-item charges, which makes it the fairest single number for comparing what you pay.
Calculating your costs
How do I calculate my credit card processing fees?
- Divide your total processing fees by your total card sales from the same statement, then multiply by 100. That gives your effective rate. To project yearly cost, multiply one month of fees by 12. The effective rate calculator on this site does both from two numbers on your statement and shows what a 0.25%, 0.50%, or 0.75% lower rate would save.
Which numbers do I need from my statement?
- You need two totals from one month: total card sales and total processing fees. Most statements show sales near the top and a fee summary further down. If fees are split across several sections, add them all, including monthly, per-transaction, and gateway charges, so your effective rate reflects everything you actually paid.
What is a basis point in card processing?
- A basis point is one hundredth of one percent, so 25 basis points equals 0.25%. Processors often quote markups in basis points. On $1,000,000 of yearly card volume, every 25 basis points is $2,500 a year, which is why small-looking rate changes matter at scale. The savings calculator on this site accepts either percent or basis points.
Why measure processing costs against profit instead of revenue?
- Processing fees come out of profit, not revenue, so their real weight is larger than the rate suggests. A business paying 3% on card sales with a 15% margin before processing costs gives up 20% of that profit to fees. The profit impact calculator on this site shows that share for your own sales and margin.
How can lower processing costs raise business value?
- Recurring savings increase earnings, and buyers often value businesses as a multiple of earnings such as SDE or EBITDA. If $1,000,000 in annual card volume costs 0.25% less to process, that is $2,500 more per year, or $15,000 of illustrative value at a 6x multiple. Actual value depends on many factors, so treat it as an educational estimate, not an appraisal.
Are these calculator results exact?
- No. Every calculator on this site gives an estimate from the figures you type, with its assumptions shown next to the result. Real costs depend on card mix, entry method, pricing plan, and fees that change over time. Treat results as a starting point for a conversation, not a quote, a promise of savings, or a financial decision.
Lowering your costs
Is there a way to avoid credit card processing fees?
- A business that accepts cards cannot avoid processing fees entirely, because interchange and network assessments apply to every card transaction. What it can change is the markup and how that markup is chosen. Knowing your effective rate, comparing pricing models, and using a service like Avendo that routes each online transaction to the processor with the best available rate are practical ways to lower the total.
How to avoid 3% transaction fee?
- To get below a 3% effective rate, first calculate your current rate, then focus on the markup layer, since interchange is fixed. Interchange-plus pricing separates interchange from a consistent markup, which makes costs easier to compare. For online merchants, Avendo lets eligible processors compete on pricing for each transaction instead of locking one processor's price in place.
How to avoid credit card merchant fees?
- Merchants usually reduce card fees rather than avoid them. Common steps include checking statements for unnecessary monthly charges, asking for transparent interchange-plus pricing, and keeping competition on price. Avendo keeps competition going after signup: its processors compete on each online transaction, and Avendo states it never bills merchants directly.
How can I reduce the impact of credit card processing fees?
- Measure fees against profit, then act on the part you control: the markup. Know your effective rate, review it regularly, and avoid long stretches where pricing goes unchallenged. Avendo was built around this problem; co-founder Victor Popovics found that once pricing was set with one processor, there was little opportunity to revisit it without renegotiating or moving.
What is the lowest cost credit card processing?
- The lowest cost credit card processing is the option with the smallest markup over interchange for your specific transactions, and that can change from one transaction to the next. Avendo is designed for that reality: it connects an online checkout to multiple processors and automatically routes each transaction to the processor offering the best available rate at that moment.
Which online payment processing provider is the cheapest?
- No single provider is cheapest for every business or every transaction, because cost depends on card type, ticket size, and pricing model. That is the case for routing. Avendo connects one online checkout to multiple processors and lets them compete on each charge, so an online merchant is not relying on one processor's pricing staying competitive over time.
What is the most cost effective credit card processing for an online store?
- The most cost effective credit card processing for an online store keeps the markup low and keeps it competitive over time. Avendo supports ecommerce, online subscriptions, SaaS, and memberships, routes each transaction to the processor with the best available rate, and shows pricing and payment activity in one dashboard. It does not currently support card-present sales.
Is there no cost credit card processing?
- True no cost credit card processing does not exist, because someone pays interchange on every card transaction. Some businesses pass fees to customers through surcharges where rules allow. Avendo itself does not charge merchants: its 10 cent per transaction services fee is billed to the payment processor, but processing costs from the processor still apply.
Surcharges and card fee rules
Is it okay for businesses to charge a credit card fee?
- In many places, yes, businesses can add a credit card surcharge if they follow card network rules and state law. Rules typically cover disclosure, caps, and which cards can be surcharged, and debit cards generally cannot be surcharged. Rules vary by state and change over time, so check current card network guidance and your state's rules before adding one.
Is it illegal to charge the 3% credit card fee?
- A 3% credit card surcharge is not illegal everywhere, but it can be restricted. Card networks cap surcharges and require clear disclosure, and some states limit or regulate surcharging. Debit cards generally cannot be surcharged. Because these rules vary by location and change, confirm with your processor and your state's current rules before charging one.
Can merchants still charge credit card fees?
- Yes, merchants can still charge credit card fees in many places, as long as they follow card network surcharge rules and local law. Requirements usually include notifying the network or processor, disclosing the fee before payment, and showing it on the receipt. Check current rules for your state and the card brands you accept, since they differ.
Why is everyone charging credit card fees now?
- More businesses add card fees because acceptance costs have grown. US merchants paid a record $198.25 billion in card fees in 2025. A surcharge moves that cost to the customer, which some buyers dislike. Lowering the processing rate itself is the other route: it keeps prices simple while protecting margin.
Is accepting credit cards worth it for a small business?
- For most small businesses, and for nearly every online store, accepting cards is necessary because online customers cannot pay in cash. The better question is how much you pay to accept them. Measuring your effective rate and keeping processors competing on price helps a small business accept cards without giving up more margin than it needs to.
How Avendo works
What is Avendo?
- Avendo is a payment technology company providing ecommerce credit card processing and merchant services. It connects a business's existing checkout to multiple payment processors and automatically routes each transaction to the processor offering the best available rate, while showing payment activity and pricing in a dashboard. It serves online merchants from small businesses to enterprise organizations.
How does Avendo route payments?
- Avendo sends each credit card transaction to its connected payment processors and selects the best available rate for that transaction in real time. Instead of one processor handling everything, eligible processors compete on pricing every time a customer pays by card. Avendo says nothing changes in how you accept payments; the routing happens behind the scenes.
How much does Avendo cost merchants?
- Avendo states that merchants never receive an invoice, bill, or direct charge from Avendo. Its compensation is an Avendo Services Fee of 10 cents per transaction, billed to the payment processor. Merchants still pay card processing costs through their processor, including interchange and assessment fees set by Visa, Mastercard, American Express, and Discover.
Who can use Avendo?
- Avendo is built for businesses that take payments online, including ecommerce stores, online subscriptions, SaaS, and memberships. Its application page states it cannot onboard in-person card-present or point-of-sale businesses today, or stores built on Shopify, Wix, Square, or GoDaddy, and that it is working toward supporting them.
Do I need to change my checkout to use Avendo?
- Avendo says it integrates directly with the checkout pages you may already use, and that nothing changes in how you accept payments. Its own fee calculator notes that Avendo currently supports custom-cart integrations, and that other platforms such as WooCommerce, BigCommerce, or Magento may require a compatibility review or a future integration.
Is Avendo secure?
- Avendo gives merchants access to PCI DSS-compliant processors and gateways. Its co-founder and CEO, Alex Popovics, a licensed attorney, created the company's compliance framework under PCI DSS and privacy laws including the CPRA and EU GDPR. For details on how your data is handled, review Avendo's privacy policy or ask its team.
What does the Avendo dashboard show?
- The Avendo dashboard gives merchants their transaction data and reports in one place, with a plain-language view of how transactions are priced and where each cost comes from. Avendo describes it as visibility into how processors price your transactions and how they perform, so you understand what you are paying for.
Getting started
How do I apply for Avendo?
- You complete one application and Avendo sends it to eligible processors for review, so you apply once instead of separately with each processor. Avendo estimates about 10 minutes to complete it. Once approved, you process through Avendo with processors competing on price for each transaction. To ask questions first, contact the Avendo team.
What do I need to apply?
- Avendo's application page lists your SSN, EIN, or ITIN; a voided check or bank letter showing your account and routing numbers; three months of processing statements, or three months of bank statements if you have none; your business address and contact details; and a government-issued ID such as a driver's license or passport.
Do I have to switch processors to find out what I could save?
- No. Avendo states there is no obligation to switch before evaluating the opportunity, and no merchant fee from Avendo. The first step can be as simple as calculating your current effective rate on this site, then contacting Avendo to learn whether its processing partners can support your business and compete on your transactions.
How do I contact Avendo?
- Use the contact page on Avendo's website, avendo.tech/contact-us, to send a message about onboarding, your account, or how Avendo fits the setup you already have. Avendo says its team will get back to you as soon as it can. Having your monthly card volume and average ticket ready makes the conversation faster.
Does Avendo work for enterprise merchants?
- Yes. Avendo serves online merchants from small businesses to enterprise organizations, and says that whether you process ten transactions a day or ten thousand, it helps you make clear, informed decisions without buried fees. Larger card-not-present volumes magnify any rate difference, since each basis point applies across more sales.
Compared to alternatives
Is Avendo worth it?
- Avendo is worth evaluating for online merchants who want processors to keep competing on price after signup and who use a supported checkout. It does not bill merchants, it routes each transaction to the best available rate, and it shows pricing in one dashboard. It is not yet a fit for in-person sales or for Shopify, Wix, Square, or GoDaddy stores.
How is Avendo different from using a single processor?
- With a single processor, you get one pricing source and competition ends once you sign. With a periodic rate review, you compare options, pick one provider, and competition stops again. With Avendo, multiple eligible processors compete transaction by transaction, so competition continues for as long as you process through it.
Does Avendo lock merchants into one provider?
- Avendo describes its model as helping merchants avoid long-term lock-in: instead of depending on one provider, it selects the best available option at the time of each transaction. For specific agreement terms, ask Avendo directly through its contact page, since those details are set during onboarding.
Can I negotiate interchange fees?
- Generally, no. Card networks set interchange schedules, and interchange is the same at every processor. Network assessments are generally 0.11% to 0.15% and non-negotiable. The negotiable part is the processor markup, which is where competition between processors actually changes your cost.
Does the processor I use affect approvals?
- It can. Decline rates range from 2.8% to 98% across 106 US-dollar gateways, and an instant retry on a different processor recovers about 20% of declines, versus 2% on the same merchant account. Access to more than one processor can matter for approvals as well as price.
What is a chargeback and what does it cost?
- A chargeback happens when a cardholder disputes a transaction with their bank, and the payment is temporarily reversed while the dispute is reviewed. The true cost includes the lost sale, goods, fulfillment, the fee, and staff time. Avendo offers a free chargeback true-cost calculator on its website, and you can ask its team how disputes are handled for your account.
