About this tool

Enter the taxable value of the fringe benefit, choose whether it is a type 1 benefit (GST-creditable) or type 2, and the FBT rate. The calculator grosses up the value and shows the FBT payable by the employer.

The calculation

FBT = taxable value × gross-up rate × FBT rate. The gross-up rate is 2.0802 for type 1 benefits, where the employer can claim GST credits, and 1.8868 for type 2 benefits. The FBT rate is 47% for the FBT year ending 31 March 2026.

Why the gross-up

The gross-up turns the benefit into the pre-tax salary an employee would need to buy it, so the tax is the same as if the same value had been paid as salary.

Notes

The FBT year runs from 1 April to 31 March. Many benefits are exempt or have special valuation rules, for example some electric cars, work-related items and small benefits. Use this for an estimate and check with a tax adviser.

Worked example

A type 1 benefit with a taxable value of $10,000 is grossed up to $20,802, and 47% of that gives FBT of about $9,777. A type 2 benefit of the same value costs about $8,868.

Tips for best results

Check every box before you rely on a result, because one wrong digit changes the whole answer. Use the exact figures from your payslip, bill, certificate or contract, and keep a note of the date you calculated. Rates, thresholds and rules change from time to time, so for tax, fees and legal matters treat the output as an estimate and confirm with the official source named on this page. You can run as many scenarios as you like; nothing is saved or sent, and refreshing the page clears the boxes.
