About the Super Guarantee Calculator
The Super Guarantee Calculator Australia helps employers and employees calculate the correct superannuation contributions required under ATO legislation. With the super guarantee rate rising to 12% from July 2025, staying compliant is more important than ever. This tool ensures you meet your obligations and avoid the super guarantee charge.
What is the Super Guarantee Calculator?
The super guarantee is the compulsory contribution Australian employers must make into their employees' superannuation funds. For FY 2025-26, the rate is 12% of ordinary time earnings — the final step of the legislated increases, effective 1 July 2025. This calculator determines the exact dollar amount an employer must contribute based on an employee's salary or wages. It applies the correct rate based on the financial year and accounts for the maximum contribution base, which is capped at $65,070 per quarter for 2025-26. The tool supports calculations for full-time, part-time, and casual employees, including those on salary sacrifice arrangements. It also helps employees check whether their employer is paying the correct amount. If an employer fails to meet the super guarantee, they must pay the super guarantee charge, which is higher than the original contribution and is not tax-deductible. This calculator is essential for small business owners, payroll officers, and independent contractors who want to ensure they meet their obligations under the Superannuation Guarantee (Administration) Act 1992.
How to Use This Calculator

- 5Add quarterly overtime and bonuses: Include any additional payments that count as ordinary time earnings for super purposes.
- 6Review the required contribution: The tool shows the minimum super contribution the employer must make each quarter.
- 7Check against the maximum contribution base: The calculator ensures contributions do not exceed the quarterly cap set by the ATO.
Worked Australian Example
Practical Example
Meet Ryan, a small business owner running a cafe in Hobart, Tasmania. He employs three full-time staff and two casual workers. Ryan wants to calculate his super guarantee obligations for the quarter. Using the Super Guarantee Calculator Australia, he enters each employee's ordinary time earnings. For his full-time barista earning $4,500 per month, the calculator shows a monthly super contribution of $540 at the 12% rate (12% × $4,500). For his casual waiter earning $3,200 per quarter, the contribution is $384. Ryan discovers his total quarterly super obligation is about $2,020 across all five employees. He sets up quarterly payments through his payroll system and avoids the super guarantee charge, which would have cost him an additional $290 plus interest. Ryan also learns he must pay super for employees under 18 who work more than 30 hours per week. The calculator helps him stay fully compliant.
How Our Super Guarantee Calculator Works
The Super Guarantee (SG) is a fixed percentage of an employee's **ordinary time earnings (OTE)** that an employer must pay into super. For FY 2025-26 the rate is **12%** — the final step in the legislated increases under the Superannuation Guarantee (Administration) Act 1992. The calculation is: **SG contribution = Ordinary time earnings × 12%** OTE is what an employee earns for their ordinary hours — base salary or wages, plus most allowances, commissions, shift loadings and paid leave. It generally **excludes** overtime worked outside ordinary hours. Two rules cap or floor the result: - **Maximum contribution base** — SG is only compulsory on OTE up to a quarterly cap. Earnings above the cap for that quarter don't attract compulsory SG. - **No monthly minimum** — since 1 July 2022 the old $450-per-month threshold is gone, so eligible employees earn SG from the first dollar. If SG isn't paid in full by the quarterly due date, the employer owes the **Super Guarantee Charge** (unpaid SG calculated on total salary and wages, plus interest and an administration fee), which — unlike ordinary SG — is not tax-deductible. Salary sacrifice does not reduce the OTE base used for SG.
When to Use This Calculator
Use this calculator whenever you need to confirm a super figure rather than assume it. **Employers and payroll staff** should run it each quarter before the payment due dates, and again whenever the SG rate changes, an employee gets a pay rise, or you take on a new hire. **Employees and contractors** can use it to check that the super appearing on payslips matches 12% of their ordinary earnings — a quick way to catch underpayment early, when it's easiest to recover. It's also useful when quoting for a role or contract: factoring 12% SG on top of a base wage shows the true cost of employment. If an employee's earnings approach the quarterly maximum contribution base, use the tool to see where compulsory SG stops.
