Superannuation Calculator

Project your Australian superannuation balance from the 12% employer guarantee and any extra contributions.

About the Superannuation Calculator

Employers must pay the Superannuation Guarantee of 12% of ordinary time earnings (from 1 July 2025). Concessional (before-tax) contributions, including salary sacrifice, are taxed at 15% in the fund and capped at A$30,000 a year; unused cap can be carried forward for five years if your balance is under A$500,000.

The formula

Each year: balance × (1 + r) + (12% × salary + extra) × 0.85

Worked example

Example: Super balance at 74 = $5,210,348

  1. Inputs: Current age: 33 years; Retirement age: 74 years; Salary (before tax): $99,000; Current super balance: $44,000; Extra concessional (salary sacrifice) per year: $0; Return after fees: 8%; Yearly salary rise: 3%.
  2. Formula: Each year: balance × (1 + r) + (12% × salary + extra) × 0.85
  3. Result: Super balance at 74 = $5,210,348
  4. Employer SG this year: $11,880
