What is a 'partial benefit' and how is it calculated?

A partial benefit pays a proportionate monthly amount when you have returned to work at reduced capacity earning less than your pre-disability income. The standard formula across the 9 panel insurers is (pre-disability income minus current income) / pre-disability income x full monthly benefit.

Partial benefits support graduated return-to-work and are particularly important for conditions with gradual recovery, like post-cancer rehabilitation, mental health, and chronic pain.

The standard formula

Partial benefit = (Pre-disability income - Current income) / Pre-disability income x Full monthly benefit

Worked example

Pre-disability income: $10,000 per month. Full monthly benefit: $7,000. You return to work at reduced capacity earning $4,000 per month.

• Income loss percentage: ($10,000 - $4,000) / $10,000 = 60%.
• Partial benefit: 60% x $7,000 = $4,200 per month.
• Combined income (employment plus partial benefit): $8,200 per month.

If your earnings rise to $6,000, the new income loss is 40%, and the partial benefit drops to $2,800.

Insurer variations to watch

• Minimum income-loss threshold. Some policies require a 20% or 25% drop before partial benefits engage. Many panel insurers do not impose this; check the PDS.
• Minimum work-capacity threshold. NEOS Protection requires the insured to be 'working but not to their full capability for at least three consecutive months' before partial benefits begin (NEOS PDS).
• Hours-based test. Futura's Income Protection Cover applies an 80% regular work-hours test alongside the income test (Futura PDS).
• Duration cap. Most policies pay partial benefits up to the same benefit-period cap as the full benefit. Some have separate partial-benefit duration caps; check the PDS.
• Medical certification. Ongoing partial-benefit claims require treating-doctor confirmation that capacity remains reduced. The medical certificate should specifically document partial work capacity, not just cleared to return to work.

Why partial benefits are valuable

Without the partial benefit, an insured facing a graduated recovery would have to choose between a full claim with no work, or full return at reduced capacity with no benefit. The partial benefit removes this binary. It also aligns with treating-doctor practice, which generally favours graduated return for most conditions.

Communication with your treating doctor

Ask your treating doctor to document:

1. The percentage of normal duties or hours you can perform.
2. The expected recovery trajectory.
3. Specific limitations (lifting, screen time, customer-facing work).
4. The recommended duration of the partial-capacity period.

This evidence supports the partial-benefit calculation at every review.

General advice only. Confirm the exact formula, minimum threshold, and duration cap against your insurer's current PDS.
