Employees deciding how much to salary sacrifice, and the advisers and payroll people who get asked "is it worth it?" and would rather show the two numbers than repeat a rule of thumb.
كيف يعمل
- Enter the amount, your marginal rate and the contributions tax.
- Read the two numbers side by side: what it cost in take-home, and what landed.
- Check the break-even against your own marginal rate — below it the answer flips.
- Enter salary, the employer rate and the cap to see how much room is actually left.
ماذا تكسب
- Shows, in the same money, how much take-home pay you really give up by salary sacrificing in Australia and how much actually lands in your super — including the cases where sacrificing loses you money.

الأسئلة الشائعة
Is my data safe if I use this calculator?
Yes. Everything is calculated in your browser—no numbers you enter are sent to or stored on any server. The page contains no tracking or data collection.
Does this tool tell me whether salary sacrificing is right for me?
No. It only shows the arithmetic: the exact take-home cost, the exact amount that lands in super, and the break-even marginal rate. It does not consider your age, balance, or other financial goals, and it will show cases where sacrificing loses money.
Does it automatically use current tax rates or caps?
No. Rates and caps change by year and jurisdiction, so the tool starts empty. You must enter your own marginal rate, contributions tax rate, and cap—it performs the math only, not the rate lookup.
