Credit Card — Interchange Revenue (Net of Rewards Cost, Gross of Network Fees)
Recording interchange revenue earned by a card-issuing bank on each cardholder transaction — the spread between the interchange fee received from the merchant's bank and the rewards cost paid to the cardholder.

| Rewards Expense / Contra-Revenue (Points/Miles/Cashback Earned by Cardholders) | Expense (+) | 142,500,000.00 | - |
| Net Interchange Revenue After Rewards | Revenue (Net) | - | 114,000,000.00 |
💡 Accountant's Note
Interchange is the fee paid by the merchant's bank (the 'acquirer') to the cardholder's bank (the 'issuer') on every credit card transaction. For a $100 purchase on a Visa Signature rewards card: interchange rate ≈ 2.15% = $2.15. Of this: Visa network assessment ≈ $0.20, rewards cost ≈ $1.07 (if the card earns 1% cashback), leaving the issuer with ≈ $0.88 net. Interchange rates vary dramatically: no-rewards debit cards earn 0.05–0.21%; premium travel rewards credit cards earn 2.4–3.0%. This is why banks aggressively market premium rewards cards — the higher interchange more than pays for the rewards. Under ASC 606, interchange is recognized point-in-time as each card transaction settles. The issuer is the principal in the cardholder-issuer relationship (it bears the credit risk on the receivable). Rewards are either a revenue deduction (if the reward is a rebate on the transaction) or an expense (if it's a loyalty program with a separate performance obligation).
Practitioner & Systems Framework
💻 ERP Architecture
Credit card processing systems (FIS, Fiserv, Jack Henry, i2c) generate daily settlement files that aggregate interchange by card type, transaction category (retail, dining, travel, gas), and network (Visa, Mastercard, Amex, Discover). The card core banking system feeds these totals to the general ledger. The Durbin Amendment (Dodd-Frank Act) caps debit card interchange at $0.21 + 0.05% + $0.01 fraud prevention for banks with $10B+ in assets — creating dramatically different interchange economics for large vs. small issuers. Network assessment fees are typically expressed as basis points of transaction volume and billed monthly by Visa/Mastercard.
⚠️ Audit Flags
Interchange revenue completeness testing: auditors reconcile total card transaction volume (from the card processing system) × weighted average interchange rate = expected interchange revenue. The rewards cost accrual is tested against the rewards program terms: are all earned points accrued at period-end even if not yet redeemed? The presentation of interchange (gross vs. net of rewards) is assessed against the ASC 606 principal/agent framework — rewards programs where the bank is the principal in both the transaction and the rewards program typically support gross presentation with separate rewards expense.
📄 Required Documentation
Card processing system daily settlement reports, interchange revenue by card type and network, network assessment fee invoices (Visa/Mastercard), rewards program liability rollforward, rewards cost accrual calculation, Durbin Amendment compliance documentation (for large issuers), and interchange revenue disaggregation by card category.
