  • Assumptions

    Before tax salary: refers to your taxable salary. This usually means your regular gross pay (before any deductions), plus commissions or other allowances that may apply. No allowance has been made for income received from sources other than salary. Such income could affect the results.

    Salary sacrifice contribution amount: It is assumed that you are eligible to contribute to super and that your employer will allow you to make the salary sacrifice contributions you enter.

    This calculator assumes that your contributions have not exceeded the concessional contributions cap. The limit for the 2019/20 year are $25,000 p.a. This calculator does not take into account unused concessional cap carry forward amounts.

    Tax paid: Income tax is calculated on a Pay As You Go (PAYG) withholding basis using 2019/20 Australian Taxation Office formulas and some rounding. Your before tax salary is converted to a weekly equivalent, tax formulas applied, then converted back to an estimated amount of tax payable based on the pay frequency you entered. The tax formulas applied assume you:

    • are an Australian resident;
    • are claiming the tax free threshold;
    • are not claiming any tax offsets (apart from the Low income tax offset where applicable) or an exemption from Medicare levy and;
    • are not repaying Higher Education Loan Program (HELP) or Student Financial Supplement Scheme (SFSS) debts.

    PAYG withholding amounts calculated by your employer may be determined on a different basis and therefore may be higher or lower than that shown in this calculator.

    Impact to my super balance: This net amount is calculated as the pay frequency equivalent of the Salary sacrifice contribution amount entered minus 15% contributions tax plus

    . The Benefit to my super balance amount also does not take into account:

    • subsequent investment returns (positive or negative);
    • fees or charges;
    • any additional tax that may be payable if you (i) have not supplied your Tax File Number, or (ii) exceed your contribution caps or (iii) are subject to the new extra 15% tax on concessional contributions for very high income earners whose combined income and relevant concessionally taxed super contributions exceed $250,000 in a financial year (Division 293 tax); or
    • any tax on withdrawal of your benefits.
    • low income super tax offset  or super co-contribution

    No allowance has been made in this calculation for inflation or other changes in the cost of living.

    For more information please read the Growing My Super Guide and How My Super is Taxed Guide and seek advice before making a decision about the contribution options that might be right for you.
