What your scenarios reveal

Compare both thresholds

Toggle between standard and fuel-efficient to see the LCT difference. A fuel-efficient vehicle at the same price attracts less LCT because the threshold is higher.

Find the LCT-free price point

Slide the price down to the threshold to find the maximum GST-inclusive price you can pay without triggering LCT. For standard vehicles, that is $80,809.

Check your state's stamp duty

Stamp duty varies by state and can add thousands to your drive-away cost. Switch states to see the impact on total on-road costs.

Factor in all on-road costs

Registration, CTP, and dealer delivery charges add up. Adjust each field to match your actual quotes and see the true drive-away figure.

How LCT works

The 33% rate

LCT is charged at 33% on the GST-exclusive amount above the threshold. The (10/11) factor in the formula removes the GST portion before applying the rate.

Two thresholds

The ATO sets separate thresholds for standard and fuel-efficient vehicles. Fuel-efficient vehicles (7L/100km or less) have a lower threshold, meaning LCT kicks in at a lower price point.

Business use refunds

GST-registered businesses purchasing vehicles primarily for business use may be eligible for a partial LCT refund. The refund amount depends on the vehicle type and business use percentage.

Annual threshold updates

LCT thresholds are indexed annually based on CPI movements and published by the ATO before each financial year. This calculator uses the 2026-27 thresholds.
