The short answer

Interchange-plus customers got the cut automatically. Flat-rate customers got it only if their provider cut the rate. On a typical card mix that is worth about 0.05 to 0.18 points of card sales, or A$25 to A$90 a month on A$50,000 (estimate, inc-GST).

    Questions

    What changed on 1 October 2026?

    The RBA cut the interchange cap on domestic consumer credit cards from 0.8% to 0.3% and on debit and prepaid cards to 8 cents or 0.16%. Surcharging on eftpos, Mastercard and Visa ended the same day. Caps are set ex-GST.

    Does my business get the saving automatically?

    Only if you are on interchange-plus (cost-plus) pricing. On a flat rate, the lower wholesale cost reaches you only if your provider lowers your rate. Compayr reported that 13 of the 20 card rates it tracks had not changed as at 16 October 2026.

    How is the expected saving worked out?

    It is my arithmetic on public RBA figures. The ceiling assumes every consumer credit payment saves the full 0.50 point cap cut and debit saves 0.04 points. The low case assumes consumer credit falls from the RBA's 0.47% average to the 0.30% cap and debit does not move. Both are multiplied by 1.1 to compare with flat rates that are published inc-GST. International cards are excluded until the 1 April 2027 cap.

    Is this financial advice?

    No. It is general information, not legal, financial or tax advice, and it is not an audit of your statement. Caps are maximums, provider rates change, and your contract may differ. Check with your provider and your accountant.

    Where do the provider rates come from?

    They are hand-keyed from public pages and dated. Several come from Compayr's published article, which is a secondary source. See the sources page for every source, its date and what it supports.
