Discount rates of 4%, 6%, 7%, and 8% are used in a range of legal and commercial contexts beyond the standard 3% and 5% rates seen in NSW personal injury claims. Understanding when these higher rates apply — and what difference they make — is an important part of any present value analysis.

Not all future costs in a personal injury claim arise weekly. One-off future expenses like surgery, equipment replacement, and home modifications require a deferred lump sum calculation — and the method is different from the approach used for ongoing losses.

Following Gray v Richards, two methodologies have developed for calculating fund management costs in personal injury matters. The Present Day Value and Actual Value approaches can produce materially different results, and understanding both is important for legal teams and their clients.

The discount rate used in a personal injury compensation assessment directly affects how large the lump sum award will be. Understanding what 3% and 5% actually mean — and why the choice matters — is essential for anyone involved in a serious injury claim.
