PRIVATE HEALTH INSURANCE PREMIUM CHANGE FORMULAS
Average insurer premium change
The Average insurer premium change is calculated according to the following formula.
(FCI with premium changes – FCI without premium changes) x 100
FCI without premium changes
Where FCI is the forecast contribution income for the insurer for the 12 month period 
following the implementation of the changes, excluding forecast changes in 
membership, and including rate protection. FCI is calculated by Monthly Premium * 
Total number of policies.
For example:
An insurer has two products and has one customer per product:
Product A – ambulance product price change from $50 to $55 (10% increase)
Product B – combined product price change from $3,000 to $3,060 (2% increase)
The average insurer premium increase in this example is around 2% (as the cheap 
ambulance product has almost no weighting).
ACT 1982 (CTH)  
Average industry premium change
The Average industry premium change is the average change in premiums for each 
product (the percentage change) offered by every private health insurer, weighted 
HEALTH AND AGED CARE 
according to the number of people covered.  It also includes rate protection (pre-
payment of premium in advance of new approved i
INFORMATION  ncrease commencing) and the age-
based discount1 (available to people aged 18-29 years) and therefore understates the 
increase that will be experienced by some policyholders.
This is the formula as set out in Section 5A of the Private Health Insurance (Incentives) 
Rules 2012 (No. 2). The rationale for

The average premium increase in this example using the above methodology is 6%.

Attachment H 
An outline of the concept of the public interest and its application to the approval of private health 
insurance premium increases
Subsection 66-10(3) of the Private Health Insurance Act 2007 (PHI Act) provides that:
“The Minister must, by written instrument, approve the proposed changed amount or amounts, 
unless the Minister is satisfied that a change that would increase the amount or amounts would 
be contrary to the ‘public interest’.”
In making a decision to approve or refuse a premium increase for a complying health insurance product, 
the Minister must assess each application upon its individual merits, and make a decision as to whether 
to approve the particular insurer’s proposed increase:
• in relation to particular products offered by the insurer that are the subject of the application
made under section 66-10 of the PHI Act; or
• in relation to all the products offered by the insurer that are the subject of the application made
under section 66-10 of the PHI Act.
The PHI Act does not define public interest nor set out matters to be taken into account in determining 
what is in the public interest for the purposes of subsection 66-10(3).  Where no such definition is 
provided in the statute, judicial authority indicates that the scope of the term public interest is indicative 
of a broad discretion, but must also be determined within the context of the relevant statutory scheme.  
ACT 1982 (CTH)  
The public interest is not merely the interest of an individual or group. Determining the public interest 
involves a discretionary value judgment, confined by the subject matter, scope and purpose of the PHI 
Act.1  Decisions relating to the public interest for the purposes of subsection 66-10
HEALTH AND AGED CARE   (3) may take into 
account different factual matters presented by the applicant in support of an increase in premium 
INFORMATION 
amount or amounts.  However, the Minister may also take into account other matters that are relevant 
to the decision being made, such as the potential impact of the increases on fund members, the overall 
impact on Australia’s fund members, and the public at large.  Section 66-10 does not appear to limit the 
kinds and sources of information that the Minister can consider in making his decision. Where the public 
interest lies in a particular decision making wi

Broader policy considerations may also be relevant to the exercise of power under subsection 66-10(3).
BY THE DEPARTMENT OF 
The impact of the refusal is relevant to the extent that any refusal may affect members of the public, 
including the policy holders of that particular insurer.  
There is a legal risk with any decision to refuse approval because the private health insurer may 
challenge that decision in court.  Ultimately it is a matter for the Minister whether he or she considers it 
would be contrary to the public interest to approve the increase.
In addition, if the Minister refuses to approve the proposed changed amount or amounts, the Minister 
must table the reasons for refusal in each House of the Parliament, no later than 15 sitting days of that 
House after the refusal decision is made.
