The headline cost of taking a year off work is just your salary — but that materially understates the lifetime impact. Three additional layers compound the cost: (1) lost super contributions during the pause, which would have grown via compound returns over the rest of your working life; (2) a 'return wage haircut' that often persists for 3-5 years after returning to work, especially if you return part-time or to a different employer; (3) lost wage progression — promotions and significant raises typically happen continuously through a career, and a year out usually means missing one year's worth of advancement that compounds for the rest of your career.

For a $110k worker pausing for 12 months at age 40 with 25 years to retirement: lost income $110k, lost super contribution $13.2k that compounds to ~$72k by retirement, and a typical 15% wage haircut for 3-5 years on return adds another $40-80k of lost cumulative earnings. Total lifetime impact: often $200-300k for a single year out — five to ten times the headline salary cost.

The point isn't that career pauses are wrong — they're often essential or genuinely worthwhile, especially for parental leave or burnout recovery. The point is to budget realistically. Mitigations to consider: voluntary super contributions during the pause (using carry-forward concessional cap if you're over the threshold-spousal contributions); spouse super contribution offset; Government co-contribution; and negotiating a phased return that minimises the wage haircut.
