Where this price sits
Still inside the NT’s quadratic zone — duty climbs faster than the price here, because the formula squares the value.
Every buyer type at $500,000
| Buyer | Duty | Notes |
|---|---|---|
| Owner-occupier or investor | $23,928.60 | — |
| First home buyer | $23,928.60 | No general FHB concession — but a new house-and-land package you will live in is duty-free, on contracts to 30 June 2027. |
The Territory calculates duty at this level with a genuine quadratic — D = 0.06571441V² + 15V, with V in thousands — so the effective rate climbs as the price does, faster than a bracket table would. There’s no general first-home concession, but a brand-new house-and-land package is duty-free for any buyer who moves in, first home or not, on a contract signed by 30 June 2027.

Add the other day-one cost to the duty: below 20% deposit, lenders mortgage insurance applies, computed here from the same published bands as our LMI calculator:
| Deposit | LMI (incl. its duty) | Duty + LMI |
|---|---|---|
| 20% deposit $100,000 | $0 | $23,929 |
| 15% deposit $75,000 | $4,530 | $28,459 (85% LVR) |
| 10% deposit $50,000 | $9,271 | $33,200 (90% LVR) |
Duty shown is the owner-occupier bill; LMI premiums vary between insurers, so read that column as a guide. Registration adds $181 (transfer) plus $181 (mortgage) in NT Land Titles Office fees — the state calculator itemises them live.
How duty moves around $500,000
Duty at every rung of the NT ladder this page belongs to — each price has its own page:
| Price | Owner-occupier duty |
|---|---|
| $500,000 ← this page | $23,929 |
| $550,000 | $27,225 |
Compared with $450,000 a step down the ladder, this price carries $3,871 more duty; going up to $550,000 would load on $3,296 on top. In-between prices do not scale smoothly here — a threshold sits between the rungs — so a quick run through the calculator settles any figure the ladder skips.
