What is Interchange-Plus Pricing?

In a Nutshell

The ability to process credit cards has a price tag. Obviously, you want to pay the lowest amount you can for each transaction, and that amount could depend on what type of payment model you set up with your processor. Today we’re taking a closer look at one such model: interchange-plus pricing.

What Is Interchange-Plus Pricing? How Can It Save Me Money?

Despite the surge of new alternative payment methods hitting the market, credit and debit cards still rule online commerce. 

The ability to accept card payments is vital to your business… but it comes at a cost.

Processors, banks, and card networks all charge a small fee for their services. How that fee is set varies depending on several factors, including the pricing structure you choose. In this post, we’re going to specifically focus on something called interchange-plus pricing: what it means, how it works, and why it may — or may not — be your best option.

What is Interchange-Plus Pricing?

TL;DR

Interchange-plus pricing is a combination of your predetermined interchange fee, plus a markup assessed by the processor.

Interchange-plus pricing, also known as “cost-plus,” is a pricing model for payment processing.

It’s a combination of your predetermined interchange fee, plus a markup assessed by the processor. That markup can be either fixed or percentage-based.

Compared to other methods, interchange-plus credit card processing offers you a high level of transparency. You have a detailed breakdown of your monthly processing fees. It’s the only model that breaks out every cost point, including any monthly fees from processor-provided services or subscription add-ons. 

Judging by the title, interchange-plus pricing should be easy to calculate and budget. In reality, that’s not always the case. Interchange fees can fluctuate based on different factors, such as card brand and type of transaction. And, if the processor fee is a percentage, it can be difficult to predict your costs until sales numbers come in.

How Is Interchange-Plus Pricing Calculated?

TL;DR

Interchange plus pricing fees are calculated by combining the interchange fees, which is percentage of the total transaction, and the agreed-upon markup from the processor, which could be a percentage or a set fee.

There are two obvious components of interchange plus pricing: the interchange, and the plus.

Interchange Fees

Interchange Fees

Interchange fees are the base fee for merchant processing rates. The fees exist to compensate card-issuing banks for their services, as well as the risk they take on by backing your electronic payments.

Fees are levied and collected by card networks like Visa and Mastercard, who then forward payment to the appropriate issuers. Each card brand sets its own per-transaction fee, which is a percentage of the total transaction amount.

Markup Costs

Markup Costs

Beyond the interchange fees, each payment processor charges a per-transaction markup fee. It’s kind of like a commission; it covers the processor’s costs associated with transaction fees, batch fees, and more. Unlike interchange fees, markups are entirely controlled by the payment processor.

Again, there’s no standard rate, but in interchange-plus plans, prices are based on either a set rate or a percentage. For example, using an interchange fee of 1.8% and a markup fee of 0.5%, a $100 transaction would end up costing $2.30.

Did You Know?

While the interchange is set, markup fees may be negotiable; higher-volume businesses may be able to secure lower markup rates.

Alternatives to Interchange-Plus Pricing

While it works well for many merchants, interchange-plus pricing may not be the best option for your business. Luckily, you have options:

Flat-Rate Pricing

Flat-Rate Pricing

This pricing model applies the same price rate to all transactions made through a given method, regardless of interchange rates and fees. You pay a set percentage on top of the pre-determined transaction rate; for example, 3% of the transaction total, plus $0.25 for every transaction.

Tiered Pricing

Tiered Pricing

By combining interchange-plus and flat-rate pricing, tiered pricing sorts all transaction types into one of three (sometimes four) categories, or “tiers”: Qualified, Mid-Qualified, or Non-Qualified. In some cases, “Rewards” is its own category. Processing rates are based on the transaction’s tier.

Subscription Pricing

Subscription Pricing

Also called membership pricing. This method is similar to interchange-plus because it separates the markup from the interchange. However, the difference is that your processor will charge you a monthly subscription fee instead of tacking on fees per transaction.

Did You Know?

There’s also a variation on these pricing methods called billback. Here merchants are charged a flat-rate for transactions processed in the preceding month. Once the monthly sales are settled, however, the merchant is charged for the difference between the flat rate and the actual cost.

Who Benefits Most From Interchange-Plus Pricing?

Interchange-plus pricing is a popular choice for a lot of merchants. But, who really benefits the most from this model?

In general, you can expect to see the best results from interchange-plus pricing if any of the following apply to you:

You’re a High-Volume Business

Interchange-plus pricing is cost-effective at scale because you’re only paying the actual interchange rate plus a small, negotiated processor markup. Unlike flat-rate pricing, where the same percentage is applied to every transaction regardless of volume, interchange-plus offers lower per-transaction costs as your total transaction volume increases.

You Do All of Your Business Online

Interchange rates are usually higher for card-not-present credit transactions due to the heightened fraud risk. But, that means you overpay on debit card transactions if you’re using flat-rate pricing, as debit transactions have lower interchange rates. With interchange-plus, you can take advantage of lower debit interchange rates while still accepting higher-cost credit payments.

You Have a High Average Transaction Value

Flat-rate models become very expensive for large purchases; simple as that. Interchange-plus pricing reduces the percentage-based cost for high-ticket items. To illustrate, you’ll pay $290 in fees to process a $10,000 transaction at a 2.9% flat rate. But, that same transaction processed at an interchange-plus rate of 1.8% + 0.2% markup will only cost you $200.

Your Business Has Low Margins

Interchange-plus pricing lets you itemize different fees. You have more transparency in cost breakdowns. This give you the power to better analyze your costs and make informed decisions about pricing strategies. In contrast, flat-rate pricing doesn't allow for itemization and can make it difficult to see where you could cut costs.

Is Interchange-Plus Pricing the Best Option for Me?

Interchange plus vs. flat rate vs. tiered pricing? The best option will ultimately depend on you. Different pricing models will work better for some organizations than for others. Finding out if interchange-plus pricing is best for you will require a little research, but here are a few questions to get you started.

This level of clarity will help you make informed decisions and establish a trusting partnership.
