Patient Charges for PBS Prescriptions: Example Calculations

Page last updated: 1 January 2026

The Pharmaceutical Benefits Scheme (PBS) co‑payment amounts and fees used in these examples are based on the fees and mark-ups from 1 January 2026. These amounts and fees are normally indexed annually. In 2026 the concessional co-payment amount will not be indexed, and the general co-payment amount will reduce to $25.00. Please note that the drug names in the example calculations are fictitious.

Example 1.1 - Under co-payment prescription with brand premium – general patient

Setting: approved PBS community pharmacy

Prescription for famicin 100mg – 30 tablets

Dispensed Price for Maximum Quantity (DPMQ) for brand supplied = $28.60
DPMQ for base price brand = $23.40
Therefore, brand premium = $5.20

DPMQ for base price brand ($23.40) ≤ general patient co‑payment amount ($25.00)

DPMQ for base price brand ≤ general patient co‑payment amount

  • prescription is under the general patient co‑payment amount

Formula for maximum total patient charge:

Step A.     DPMQ (for base price) + Safety Net recording fee + Additional Patient Charge (capped at the amount of the general patient co‑payment amount if sum is greater)

Step B.     Add brand premium (if any)

Stepwise calculation

Step A.

  • DPMQ $23.40 + Safety Net recording fee of $1.45 = $24.85 Subtotal is less than the general co‑payment amount of $25.00, therefore no capping required.
  • $24.85 + additional patient charge of $2.79 = $27.64.

Sum of components is greater than the maximum general patient co-payment amount.
Charge is capped at general patient co‑payment amount of $25.00.
The Additional Patient Charge component is limited to $0.15 ($25.00 - $24.85).

Step B.

  • $25.00 + $5.20 brand premium
    Maximum total patient charge = $30.20

For a PBS supply in this example, the pharmacist may charge any amount up to $30.20. If the amount charged is more than $30.20, the prescription is considered a non-PBS prescription (the supply would be considered a private prescription and none of the amount paid would count towards the patient’s PBS Safety Net).

Formula for amount to Safety Net

DPMQ + Safety Net recording fee (capped at the maximum general patient co‑payment amount or capped at the amount charged if less than the co-payment amount)

Stepwise application

  • $23.40 + Safety Net recording fee of $1.45 = $24.85 (no capping required)

    If amount charged is ≥ $24.85 and ≤ $30.20; the amount towards the Safety Net = $24.85
    If amount charged is less than $24.85; the amount towards the Safety Net = amount charged.
    If the amount charged is greater than $30.20; the prescription is non-PBS and the amount that counts towards the Safety Net is nil

The Additional Patient Charge (up to $2.79) component does not count towards the Safety Net. The brand premium does not count towards the Safety Net.

Example 1.2 - Under co-payment prescription – general patient

Setting: approved PBS community pharmacy

Prescription for ramaten 25mg – 28 capsules

DPMQ for brand supplied = $17.86
DPMQ for base price brand = $17.86

  • prescription is under the general co‑payment amount with no brand premium.

Formula for maximum total patient charge:

Step A.     DPMQ + Safety Net recording fee + Additional Patient Charge (capped at the amount of the general patient co‑payment amount if sum is greater)

Step B.     Add brand premium (if any)

Stepwise calculation

Step A.

  • DPMQ $17.86 + Safety Net recording fee of $1.45 = $19.31
  • Subtotal is less than the maximum general co‑payment amount of $25.00 - no capping required.
  • $19.31 + additional patient charge $2.79 = $22.10 (no amounts reduced by capping).

The pharmacist can charge any amount up to $22.10.

Step B.

  • Not required as no brand premium.

Formula for amount to Safety Net

If amount charged is ≥ $19.31 and ≤ $22.10; amount to Safety Net = $19.31.
If amount charged is less than $19.31; amount to Safety Net = amount charged.
If the amount charged is greater than $22.10; the prescription is non-PBS and the amount that counts towards the Safety Net is nil.

Example 2.1 - Over co-payment prescription with brand premium – general patient

Setting: approved PBS community pharmacy

Prescription for natamicin 500mg – 100 tablets

DPMQ for brand supplied = $57.00
DPMQ for base price brand = $53.60
Therefore, brand premium = $3.40

DPMQ for base price brand ($53.60) > maximum general patient co‑payment amount ($25.00)

  •  prescription is over the general co‑payment amount

Formula for maximum total patient charge:

Step A.     general patient co‑payment amount.

Step B.     add price premium (if any)

Stepwise application

Step A.

  • The maximum general co‑payment amount of $25.00

Step B.

  • $25.00 + $3.40 = $28.40

The pharmacist can charge $28.40. Any other charge means the prescription is non‑PBS (the supply would be considered a private prescription and none of the amount paid would count towards the patient’s PBS Safety Net).

Formula for amount to Safety Net

If amount charged is $28.40, the amount to Safety Net = $25.00.

If the amount charged is more than $28.40, the prescription is non-PBS and the amount to be recorded against the patient’s Safety Net is Nil.
