What does Westpac cost per month in real terms?

Using the midpoint indicative rate of 1.2%:

  • $10,000/month in card payments = approximately $120/month in fees ($1,440/year) plus monthly service fee
  • $25,000/month in card payments = approximately $300/month in fees ($3,600/year) plus monthly service fee
  • $50,000/month in card payments = approximately $600/month in fees ($7,200/year) plus monthly service fee

The monthly service fee of approximately $20 applies regardless of volume. After October 2026, none of these costs can be recovered from customers as a surcharge on Visa, Mastercard, or EFTPOS transactions.

When Westpac makes sense: Merchants already banking with Westpac may find value in consolidated banking and merchant services with a single provider. High-volume merchants can negotiate meaningful rate reductions. Westpac's terminal ecosystem supports major Australian POS systems.

When a fintech alternative makes sense: For merchants wanting transparent published rates with no negotiation required, Tyro at 1.4% or Square at 1.6% are straightforward. For zero transaction fees at the counter without any change to the existing setup, QwikPay sits alongside any Westpac terminal as an additional option.

Does Westpac offer least-cost routing?

Yes. Westpac offers least-cost routing on eligible terminals, routing contactless debit card transactions over the cheapest available network.

What does the October 2026 surcharge ban mean for Westpac merchants?

From 1 October 2026, Westpac merchants can no longer add a surcharge to Visa, Mastercard, or EFTPOS transactions. Your merchant service fee continues - it comes out of your margin. The RBA's interchange reductions will lower Westpac's wholesale costs. Westpac is required to report quarterly on pass-through from January 2027. Contact Westpac before October to understand your post-ban effective rate and whether any reductions will flow to your merchant agreement.
