Also called: Mastercard Merit Rates, Merit I, Merit III
What Merit is
Merit I and Merit III are Mastercard purchase interchange programs. Interchange is the fee paid to the customer’s card-issuing bank, not a Mastercard assessment or your processor’s markup. Mastercard sets the program requirements and publishes the rates.
The program name alone does not tell you the full cost. The card type, transaction details, and whether you meet the program’s requirements all matter. Mastercard’s published schedule effective April 22, 2022, listed Merit I Core consumer credit at 1.95% plus $0.10 per transaction, and Merit III Base at 1.65% plus $0.10.
You cannot negotiate Mastercard interchange, but you can prevent avoidable downgrades and negotiate your processor’s markup.
How Merit I and Merit III differ
Merit I commonly covers card-not-present payments, including online, mail-order, and phone-order sales. Merit III is associated with qualifying face-to-face transactions. The published qualification schedule specified settlement within 3 days for Merit I and 2 days for Merit III, with exceptions for some transaction types.
Those windows are not the only requirements. A transaction that misses a program’s card, authorization, merchant-category, or settlement conditions can be assigned a different interchange category. Mastercard’s schedule also listed a $0.15 interchange compliance downgrade fee for transactions it adjusted or downgraded, plus a $0.02 report fee on those transactions.

What Merit means for your costs
The published April 22, 2022 schedule shows why the category matters: on a $100 Core credit sale, the listed Merit I rate calculates to $2.05, while Merit III calculates to $1.75. Those dollar totals are illustrative calculations using historical published rates, not a promise of your current rate.
Rates also differ by card tier. In that same schedule, Merit I Core credit was 1.95% plus $0.10, while Merit I World High Value and World Elite were 2.60% plus $0.10. Your final processing cost includes interchange, network assessments, and processor markup. Only the markup is negotiable.
Where Merit appears on your statement
Statement labels depend on the processor. Examples include “MERIT 1,” “ENHMERITI,” “MCW MERITI,” and “Merit 1 DB.” Debit or prepaid lines can appear as “DB,” “PPD,” or “PP.” Some statements do not itemize interchange at all.
Compare the category and rate charged with the transaction type, card entry method, authorization details, and settlement date. A repeated, unexplained switch to a more expensive category is worth investigating. A single different category does not prove an error because card tier and transaction details also affect the rate.
What you can actually change
You cannot negotiate Mastercard’s interchange rate. You can reduce avoidable downgrades by meeting the requirements for the transaction category, settling on time, and sending accurate transaction and merchant-category data. You can also negotiate the processor markup that sits on top of interchange.
- Check the category. Find lines labeled “MERIT 1,” “Merit III,” or similar, then compare the category with the sale type and card-entry method.
- Review settlement timing. Compare transaction dates with batch settlement dates. The published qualification schedule used 3 days for Merit I and 2 days for Merit III, subject to listed exceptions.
- Separate the markup. On an interchange-plus statement, separate interchange from processor markup before negotiating. The interchange rate is set by Mastercard; the markup is negotiable.
- Investigate repeat downgrades. Compare repeated higher-cost categories with authorization, merchant-category, and settlement records. Mastercard’s schedule listed a $0.15 downgrade fee and a $0.02 report fee on affected transactions.
Frequently asked questions
Is Merit a Mastercard network fee?
Merit I and Merit III are Mastercard interchange programs. Interchange goes to the cardholder’s issuing bank. Mastercard assessments are a separate network cost, and your processor’s markup is another separate part of the bill.
What is the difference between Merit I and Merit III?
Merit I commonly applies to card-not-present transactions, while Merit III is associated with qualifying face-to-face transactions. Their qualification requirements and rates differ. The published schedule used settlement windows of 3 days for Merit I and 2 days for Merit III, with exceptions.
Can my processor negotiate a lower Merit rate?
No. Mastercard sets the interchange program rates. Your processor markup is negotiable, and you can reduce avoidable downgrade costs by meeting the applicable transaction and settlement requirements.
Why does my statement show a Merit downgrade?
A transaction can move to a different category when it does not meet the relevant program requirements. Compare the statement line with the transaction’s card-entry method, authorization, merchant-category data, and settlement date. A repeated pattern can point to a processing setup or workflow issue.
