How Much Do You Save Switching From Stripe to Interchange?

How much can I save per transaction by switching from Stripe to an interchange-based provider?

Your savings come from the gap between Stripe's flat, marked-up rate and the actual interchange cost set by the card networks, plus what dual pricing shifts off your bottom line entirely. Stripe charges a flat percentage on every card transaction, no matter the actual network cost behind that specific card. An interchange-based provider passes through the real network rate and adds a smaller, transparent markup — and with dual pricing, the card-price and cash-price are shown separately, so the cost of accepting a card is covered by the customer who chooses that option rather than absorbed into your margin on every sale.

The exact dollar difference depends on your ticket size, card brand mix, and monthly volume, which is why a blanket percentage isn't useful here. The Stripe fees vs. interchange-plus comparison is worth reading in full before you try to estimate your own numbers, because it walks through the mechanics rather than quoting a single figure that won't apply to your business.

Why does Stripe cost more per transaction than an interchange-based provider?

Stripe bundles the interchange fee, the card network assessment, and its own processing margin into one flat percentage, so you're paying Stripe's markup on top of the network cost on every single swipe, tap, or online charge. That bundling is convenient to set up, but it also means you have no visibility into how much of what you're paying is the actual cost of moving money between banks versus how much is Stripe's profit on the transaction.

An interchange-based provider separates those two pieces instead of hiding them inside one number. You see the interchange rate the card networks set for that specific card type — rates vary between debit, rewards credit, and corporate cards — plus a clearly stated processor markup layered on top. Because that markup is smaller and disclosed line by line, merchants typically see the per-transaction cost drop once they move off a flat-rate model, particularly on the lower-cost debit and basic credit transactions that make up a large share of most merchants' volume. The Stripe fees vs. interchange-plus breakdown walks through exactly how that separation plays out across different card types, which is the level of detail a flat percentage can never give you.

How does dual pricing change what I actually pay per transaction?

Dual pricing removes the processing cost from your side of the transaction on card sales entirely, because the card-price and cash-price are shown separately and the customer selects which one applies before the sale is complete. Instead of a flat percentage quietly reducing your margin on every card sale regardless of how the customer pays, the cost is transparently reflected in the card price shown at checkout or on the menu, invoice, or point-of-sale screen.

This is a structural change to how the cost moves through your business, not just a rate change on paper. With Stripe, your per-transaction cost is fixed no matter how the customer pays — you absorb it whether the sale is cash, debit, or a premium rewards card. With dual pricing through MidPay, your cost exposure shifts with customer choice. Cash payments carry no card processing cost at all, and card payments show the customer exactly what the card option costs before they commit to it, so there's no surprise at settlement and no quiet erosion of your margin over the course of a month.

For merchants who currently do a healthy mix of cash and card, this is often where the bigger share of savings shows up — not just in the rate itself, but in how much of your total card volume no longer touches your margin at all. Businesses with thinner margins per sale, like convenience retail or quick-service food, tend to notice this shift the fastest, since even a small per-transaction cost adds up quickly across high volume.

How much can I save per transaction by switching from Stripe to an interchange-based provider?

The savings per transaction is the difference between what Stripe would have charged on that sale and what you pay under an interchange-based model, plus whatever dual pricing shifts to the card-paying customer instead of your margin. Because Stripe's flat rate doesn't move with your volume or card mix, and interchange rates and markups do, the gap tends to widen for merchants who process consistently or who carry a higher share of debit and lower-cost card types in their transaction mix.

There's no single number that applies to every merchant here — it depends on your average ticket size, your card brand mix, and your monthly volume, all of which vary enough between businesses that a headline percentage would be misleading rather than useful. That's exactly why we built a dedicated page for this comparison rather than quoting a blanket savings figure: see the full Stripe vs. interchange-plus comparison to work through the mechanics with your own numbers in mind, or talk to the Margin desk directly for a walkthrough of what your specific statement would look like under each model.

Does switching from Stripe mean I have to change my checkout or point-of-sale setup?

Moving processors is an operational question separate from the pricing question, and it's one worth asking before you commit to a switch so there are no surprises mid-transition. What actually determines your savings is the pricing model — flat-rate bundled fees versus interchange-based dual pricing — not the checkout technology sitting on top of it.

Before switching, confirm how your current checkout or point-of-sale system integrates with the new processor, and how dual pricing displays to the customer at the register or online so the card and cash prices are shown clearly and separately. A rate comparison that's accurate on paper only pays off if the switch itself is operationally smooth for your staff and your customers — mismatched receipts, confusing signage, or a clunky terminal update can eat into the goodwill a lower rate builds with your regulars.

Is dual pricing legal and will customers understand it?

Dual pricing is a pricing display method: it shows customers the card price and the cash price as two separate, clearly stated numbers before they choose how to pay. The customer sees both prices side by side and decides, which is why clear signage and transparency at the point of the price display matter more than anything else in how customers experience it.

Merchants adopting dual pricing should focus on clear checkout messaging and visible signage so customers aren't caught off guard at the register or during checkout online. The specific mechanics of how card and cash prices are presented — on receipts, at the terminal, or on an invoice — are part of what a provider walkthrough should cover before you switch, since presentation varies by business type. It's a conversation worth having directly with the Margin desk rather than guessing at how it should look for your specific setup.

What does this actually look like on a real statement?

Take a merchant running $50,000 a month in card volume with a 60% debit / 40% credit mix — a common split for a counter-service retail or restaurant business. Under MidPay's interchange-plus structure, that mix lands at a blended 1.49% on the debit share and 2.69% on the credit share. A typical flat-rate processor, by contrast, charges a single bundled rate around 2.6% plus 10 cents per transaction regardless of card type, because it isn't passing through the cheaper debit interchange at all — it's charging the credit-level rate on every swipe. Run that math at $50,000/month and the gap works out to roughly $378 a month, or $4,536 a year, in processing cost difference alone, before dual pricing shifts any of the remaining card cost to the customer.

That gap exists because debit interchange is structurally cheaper than credit interchange under both Visa's and Mastercard's published rate schedules, and a flat-rate processor's single blended percentage is priced to cover its most expensive card type across every transaction — including the cheap ones. The wider your debit share, the more of that spread you're leaving on the table under a flat rate. The same logic applies whether the extra cost shows up as a bundled rate or as a mislabeled card-use fee — see our breakdown of convenience fees vs. surcharges vs. service fees for how three different fee structures get confused on a receipt.

What's the fastest way to find out what I'd actually save?

The fastest path is to compare your actual Stripe statement against an interchange-based, dual-pricing quote rather than estimate from an industry-wide percentage that doesn't reflect your specific card mix. Every merchant's ticket size, card brand distribution, and monthly volume are different enough that a generic savings number won't reflect what you'd actually see on your own statement.

Start by understanding the mechanics behind the two pricing models, then get a rate specific to your business rather than relying on a rough estimate. The Margin by MidPay desk can walk through your numbers directly at 1-855-464-3576, and can explain exactly how dual pricing would display for your specific checkout or point-of-sale setup, so you know what to expect before your first statement under the new model arrives.

Frequently asked

What is interchange-based pricing?

Interchange-based pricing passes through the actual rate set by the card networks for each transaction, then adds a separate, disclosed processor markup on top, rather than bundling everything into one flat percentage like Stripe does.

What is dual pricing?

Dual pricing is a checkout method where the card price and cash price are shown separately, letting the customer choose how to pay and see the cost difference before completing the sale.

Does dual pricing cost my business anything?

Dual pricing shifts the card processing cost into the displayed card price rather than absorbing it into your margin on every sale, so the customer who chooses to pay by card covers that cost directly.

Will my savings be the same as another merchant's?

No. Savings depend on your ticket size, card brand mix, and monthly volume, which differ business to business — that's why a generic percentage isn't a reliable way to estimate your own numbers.

Do I need new hardware to switch from Stripe?

That depends on your current checkout or point-of-sale setup. Confirm integration and how dual pricing will display at your register or online checkout before switching.

Is dual pricing confusing for customers?

Dual pricing is designed to be transparent: customers see both the card price and cash price clearly before choosing how to pay, so clear signage and checkout messaging are key to a smooth experience.
