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.

A lump sum compensation award is not simply a weekly loss figure multiplied by the number of years remaining. Life expectancy determines the period over which future losses are projected, and small differences in that period can produce large differences in the final award.

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.
