Different questions need different calculations
Start with the evidence you already have. Each tool below answers a separate question and keeps entered numbers in your browser.
Calculate the all-in effective rate
Use matching sales, fee, and transaction totals to establish a statement-level baseline.
Use the main calculator →Check whether the rate is moving
Combine up to three months with a sales-weighted trend instead of averaging percentages.
Open the trend analyzer →Reconcile statement categories
Group summary fee lines, compare them with the reported total, and identify the largest category.
Open the fee worksheet →Compare modeled monthly cost
Apply the same sales and transaction inputs to flat-rate and interchange-plus assumptions.
Compare pricing models →What May Be Included in Credit Card Processing Fees?
Processing costs are made up of several parts. Here is what each term generally means in plain English.
Interchange fees
Set by card networks and paid to the card-issuing bank. They vary by card type and how the card is accepted.
Card-network assessments
Fees charged by Visa, Mastercard, Discover, and American Express for using their networks.
Processor markup
What your processor adds on top of interchange and assessments as its margin.
Per-transaction fees
A fixed amount charged for each individual card transaction you run.
Monthly account fees
Recurring statement, account, or service fees billed each month regardless of volume.
PCI compliance fees
Charges tied to meeting card-data security standards, sometimes billed monthly or annually.
Gateway fees
Fees for the software that authorizes online or keyed-in payments.
Equipment fees
Costs to buy, lease, or rent card terminals and point-of-sale hardware.
Chargeback fees
Fees applied when a customer disputes a transaction and it is reversed.
Common Warning Signs to Review on a Processing Statement
These situations are worth investigating. They do not always indicate a problem, but understanding each one helps you make informed decisions.
Fees increased without notice
Compare your current statement to previous months. Fee increases without written notice may warrant a call to your processor or a review of your agreement.
PCI non-compliance fee
This fee is charged when you have not completed the required annual Self-Assessment Questionnaire. Completing the SAQ may prevent or remove this fee depending on your processor and agreement.
Fees with no clear description
Every charge on your statement should have a legible description. Vague labels like "miscellaneous" or "other charges" are worth asking about.
Monthly minimum being triggered regularly
If you are paying a monthly minimum charge consistently, your pricing structure may not match your volume or transaction pattern.
Terminal lease costing more than the hardware
Long-term leases on low-cost hardware can significantly exceed the outright purchase price. Review total remaining lease payments versus the cost of buying.
Effective rate noticeably higher than advertised rate
A large gap between the rate you were quoted and your effective rate may reflect higher-cost card types, downgrades, or fees not explained at signup.

The result comes from your statement—not a hidden benchmark
Merchant Fee Analyzer does not estimate your cost from an industry label. The core calculation uses the sales and fees you enter. Examples are marked as illustrations, and pages link to primary sources where network, security, or regulatory context matters.
- Deterministic formulas
- The same valid inputs produce the same result; formulas are displayed and tested against worked examples.
- No universal “good rate” claim
- Card mix, ticket size, channel, volume, industry, risk, and contract terms differ between merchants.
- Primary-source preference
- Network schedules, PCI SSC material, regulators, and relevant industry bodies are preferred for factual context.
- Clear limits
- Tools organize entered numbers. They do not verify a contract, guarantee savings, or replace professional advice.
Frequently asked questions
Your effective rate is your total processing cost for a period divided by your total card sales for that period, expressed as a percentage. It captures every fee, not just one advertised percentage.
