Superannuation Concessional Cap & Salary Sacrifice Calculator

Concessional contributions — employer Super Guarantee, salary sacrifice and personal deductible contributions — are capped at $32,500 per year and taxed at 15% inside the fund. Sacrificing salary converts income taxed at your marginal rate into contributions taxed at 15%, so the benefit is the gap between the two. Exceeding the cap means the excess is taxed at your marginal rate with an interest charge. Worked example: on a $110,000 salary the employer's 12% super guarantee is $13,200. Adding $10,000 of salary sacrifice brings concessional contributions to $23,200, which leaves $9,300 of headroom under the $32,500 cap. At a 32% marginal rate (30% plus the 2% Medicare levy) the sacrificed $10,000 is taxed at 15% inside the fund instead, saving about $1,700. Unused cap amounts can sometimes be carried forward if your balance is under $500,000.
