Use the all-state calculator for an SA figure or to compare states.
Every figure below comes from South Australia's current published schedule, run through the same engine as the calculator. Examples use a new passenger car. The effective rate column is what you actually pay as a percentage of the price, which is not the headline rate wherever the schedule has bands or thresholds.
| Car price | Stamp duty | Effective rate |
|---|---|---|
| $15,000 | $540 | 3.60% |
| $25,000 | $940 | 3.76% |
| $35,000 | $1,340 | 3.83% |
| $45,000 | $1,740 | 3.87% |
| $60,000 | $2,340 | 3.90% |
| $80,000 | $3,140 | 3.93% |
| $100,000 | $3,940 | 3.94% |
South Australia's scale has four tiers for private cars, but the calculator's supported light-commercial category never reaches the fourth. A private car over $3,000 pays $60 plus $4 per $100 of the excess; a light commercial vehicle over $2,000 pays $30 plus $3 per $100 and stays there at any value. On a $50,000 vehicle that is roughly $1,940 against $1,470, a gap of about $470 that comes purely from how the vehicle is classified. SA also applies a $5 minimum on very low-value transfers.
The same $45,000 vehicle value, priced through all eight schedules. Comparison assumes a new ordinary passenger car with no concessions. QLD uses the 1–4-cylinder category and the ACT uses the C-category (176–220 g/km). That ranks 5th of 8 nationally, $390 more than New South Wales (the cheapest) and $847.50 less than Western Australia (the dearest).

| QLD | $1,350 | 3.00% |
| NT | $1,350 | 3.00% |
