These rates come directly from Mastercard’s published interchange table and are subject to change.
These rates apply to unregulated debit card transactions. Regulated debit card transactions (that is, transactions made with a debit card issued by a bank that has more than $10 billion in assets) have different interchange fees that are capped by law.
Merit 3 Interchange Requirements
As with all interchange categories, you’ll need to meet certain requirements to receive Merit III rates. If a transaction fails to meet criteria, it can “
downgrade” to a more expensive interchange category.
For a transaction to qualify for Merit III, it must be:
- Settled within one day of authorization
- Processed by electronically reading information from a customer’s card
As noted earlier, each Merit 3 Mastercard interchange category has three pricing tiers used to provide lower rates to businesses that have higher gross Mastercard sales volume.
Merit 3 Base does not have a volume requirement and has the highest associated fees, followed by
Tier 3, then
Tier 2, and finally
Tier 1 which has the lowest interchange fee but requires the highest amount of annual sales.
Statement Abbreviations
On monthly processing statements that show interchange categories, the Merit III categories may be abbreviated. Processors can use their own names or abbreviations. However, here are some common ones you may see:
- MERIT III (for Merit III Base credit)
- MER3 T1 C (for Merit III tier 1 credit)
- MER3 T2 C (for Merit III tier 2 credit)
- MER3 T3 C (for Merit III tier 3 credit)
For rewards cards, the abbreviation often starts with ENH (for enhanced), MCW (for Mastercard World), HV (for High Value), or MWE (for Mastercard world elite.) As with the core credit abbreviations above, you may see “T1,” “T2,” or “T3” to refer to the tier. If there is no tier number, it’s likely base merit 3. However, some processors do write out the entire word or name, as seen in this statement example:

Since each processor can choose how to display the interchange categories, here are some of the common abbreviations you may see for rewards Merit III.
- ENH MER 3
- MCW MERIT3
- HV MERIT3
- MWE MERIT3
- ENH MER3T1
- MCW MER3T1
- HVMERIT3T1
- MEW MER3T1
- ENH MER3T2
- MCW MER3T2
- HVMERIT3T2
- MEW MER3T2
- ENH MER3T3
- MCW MER3T3
- HVMERIT3T3
- MEW MER3T3
However, keep in mind that your processor may use other names or abbreviations.
Debit and Prepaid Abbreviations
For debit and prepaid Merit III categories, you may see similar abbreviations as the non-rewards credit card categories above, just with a “D” or “PP” (for debit or prepaid) instead of C for credit. Some examples include:
- MERIT 3 D
- MER3 T1 D
- MER3 T2 D
- MER3 T3 D
- MERIT 3 PP
- MER3T1 PP
- MER3T2 PP
- MER3T3 PP
As with the credit abbreviations, your processor makes the final decision on labeling. Additionally, on some statements, you won’t see interchange-level detail. For example, many flat rate processing companies (such as Square and Stripe) don’t provide information about the interchange categories that applied to your transactions. That doesn’t mean that you were exempt from interchange fees. Rather, it means your processor is not showing you which interchange categories applied.
Lowering Processing Rates
Ultimately it's not possible to lower your interchange fees. (Unless you're receiving
padded interchange from a shady processor.) However, that doesn't mean you can't lower your total cost of processing. Instead of focusing on interchange, which you can't negotiate, you need to focus on what's negotiable: your processor's markup. Start by determining what you should be paying for processing with the most competitive options out there.
