What's Least Cost Routing (LCR)?

  • In Australia, Multi-Network Debit Card (MNDC) transactions are processed through one of three networks: Mastercard, Visa or eftpos. Each network charges different rates per transaction, which are then included in your monthly merchant fees.

    By opting into LCR², you can choose which network (Mastercard/Visa/eftpos) these payments are sent through. This could help you save on costs for your business.

    LCR is an optional feature, giving you the opportunity to save on fees whenever customers make an eligible payment in-person and on selected terminals.

Understanding the options

If you opt-in to LCR you'll be asked to select one of three options for processing customers' tap-and-go MNDC transactions. Which one you choose will depend on your individual business and determine your potential savings. Before you decide, take the time to look at your transaction volumes, card mix and turnover in your most recent merchant statement to make the most cost-effective choice.

Option 1: Mastercard and Visa networks only

  • Process all eligible MNDC transactions via Mastercard and Visa networks only
  • Generally charged as a percentage fee per transaction
  • For example, assume that the percentage fee is 1%. If your average sale size is $40, you would pay about 40c per transaction.

Option 2: eftpos network only

  • Process all eligible MNDC transactions via eftpos network only
  • Generally charged as a flat fee per transaction
  • For example, assume that the flat fee is 30c. If your average sale size is $40, you would pay about 30c per transaction

Option 3: Set a threshold to route transactions based on value

  • Set a threshold limit and process all transactions up to and including the threshold through your chosen primary network, and above the threshold through the secondary network
  • For example, assume the Visa/Mastercard percentage fee is 1% and the eftpos flat fee is 30c
  • If you were to set a threshold of $30, so that sales up to and including this limit are processed using the Mastercard and Visa networks at a cost of 1% per transaction, sales greater than $30 would be processed using the eftpos network at a cost of 30c per transaction.

How it works

Read our case studies outlining how three businesses might benefit from each of the LCR options.

Luke's coffee store – Mastercard and Visa only option

Luke runs a cafe where he sells a lot of coffee. His average sale size is $5.

As per his pricing schedule, debit transactions processed through the Mastercard or Visa networks incur an average of 1.2% in transaction fees. Debit transactions processed through the eftpos network incur 25c per transaction.

Based on Luke's average sale size of $5, routing customers' MNDC tap-and-go transactions through Mastercard and Visa networks would cost him an average of 6c per transaction. Routing these transactions through eftpos would cost him 25c per transaction. Luke realises it's cheaper for him to enable LCR to route these transactions through the Mastercard and Visa networks.

Current fees: Visa and Mastercard only - average $5 x 1.2% = 6c per transaction

Alternative option fees: 25c per transaction

Sam's restaurant – eftpos only option

Sam runs an upscale restaurant where the average meal costs $150. Sam pays an average fee of 2% for each debit payment processed through the Mastercard or Visa networks. She discovers that it would only cost her a flat rate fee of 35c for each payment processed through the eftpos network.

Based on an average sale size of $150, Sam pays $3 in fees if LCR is not enabled. She decides to enable LCR on her terminal and sets the MNDC tap-and-go transactions to be routed through the eftpos network for the 35c flat rate, and by doing so saves an average of $2.65 per sale.

Current fees: Visa and Mastercard only - average $150 x 2% = $3 per transaction

Alternative option fees: 35c per transaction

Sandra's gift shop  Set a threshold to use both

Sandra runs a gift shop where her average sale size is $25. Sandra pays an average transaction fee of 1.2% for debit payments processed through the Mastercard and Visa networks. Sandra discovers that it would cost her a flat fee of 30c for every debit transaction processed through the eftpos network.

She works out that she’d be best off using LCR and setting a transaction threshold limit of $25. This way, MNDC transactions up to and including the value of $25 will be processed using the Mastercard or Visa networks at a cost of 1.2% per transaction, and debit transactions greater than $25 will be processed using the eftpos network at a cost of 30c per transaction.

With this approach, Sandra will pay a maximum cost of 30c per transaction and for debit transactions less than $25 in value, the fee will always be less than 30c per transaction.

Current fees: $5 x 1.2% = 6c and $25 x 1.2% = 30c and $45 x 1.2% = 54c

Alternative option fees: $5 x 1.2% = 6c and $25 x 1.2% = 30c and $45 will incur the flat fee of 30c

FAQs: What transactions and cards are covered?

LCR only applies to tap-and-go MNDC  transactions. This means that the card must have a Mastercard or Visa logo on one side and the eftpos logo on the other. Most debit cards in Australia are MNDC. Tap-and-go credit card transactions are not covered because they default to their issuer’s network.
