Payments transaction expense rate measures transaction expense divided by total payment volume under the issuer's definition.

For PayPal:

transaction expense rate = transaction expense ÷ total payment volume

It is a direct transaction-cost intensity measure, not a total operating expense ratio.

The rate connects payment scale with direct processing cost

PayPal reported a transaction expense rate of 0.90% in the second quarter of 2026.

The rate was also 0.90% in the first quarter.

Changes can reflect funding mix, payment method, merchant mix, geographic mix, network pricing, and other processing-cost factors.

Transaction expense is only one part of transaction economics

PayPal separately reports transaction and credit losses and transaction margin.

A stable transaction expense rate does not guarantee stable transaction margin if credit losses, pricing, mix, or other revenue components change.

The denominator is TPV

Because the rate uses total payment volume rather than revenue, it should not be compared directly with operating expense as a percentage of revenue.

Primary-source examples

Payments transaction expense rate is most useful as a direct transaction-cost intensity measure. Read it with TPV, transaction loss rates, pricing, funding mix, and transaction margin.

Part of the Payments Network & Platform Operating Model

Connect payment volume, transaction count, cross-border mix, account engagement, transaction costs, network revenue composition, value-added services, transaction losses, and transaction margin to understand payment-network and platform economics.

How the model fits together
  • Network scale and international mix: Payment volume shows dollar activity, processed transactions show activity count, and cross-border volume growth shows international mix. Issuer definitions differ across Visa payments volume, Mastercard gross dollar volume and switched transactions, and PayPal TPV and payment transactions.
  • Platform engagement and transaction cost: Active accounts and transactions per active account describe PayPal platform reach and engagement, while transaction expense rate places direct transaction expense on TPV. These platform metrics should not be treated as card-network equivalents.
  • Revenue composition and contribution economics: Visa service revenue is primarily linked to payments volume, data processing revenue to transaction processing, and international transaction revenue to cross-border activity. Mastercard value-added services revenue adds a non-network growth layer. PayPal transaction and credit loss rate and transaction margin connect payment activity to loss intensity and transaction-level contribution under PayPal's non-GAAP definitions.
