You receive invalidity pay based on 76.5% of your annual rate of pay for super purposes. If classified Class A, you cannot commute your entitlement.
You receive invalidity pay based on half a class A pension (38.25%). However, if you completed 23 years or more of effective service, your invalidity pay will be higher as it will be based on the number of years served, up to a maximum of 40 years.
If classified Class B, you cannot commute your entitlement.
You receive a lump sum benefit (and in some cases, a gratuity as well) if you served less than 20 years. Your lump sum will consist of a refund of your contributions to DFRDB multiplied by a factor of 1.5. However, if you have served 20 years or more or reached your retirement age for your rank, you would be entitled to retirement pay had you retired on grounds other than invalidity.
You receive a benefit equivalent to retirement pay, at a rate determined by your length of service if it is greater than your invalidity benefit. If classified Class C, you can elect to commute your entitlement.
