Every New Zealand seller gets handed a marketing schedule with two or three options on it, and almost nobody is given a way to judge them. This calculator gives you one. Put in the price you realistically expect, then put in the two packages you have been quoted, and it tells you the only number that matters: how much more the property has to sell for before the dearer campaign has paid for itself. That number is always larger than the price difference between the packages, for two reasons people routinely forget. First, marketing attracts 15% GST and a private homeowner cannot claim it back, so a $4,000 difference is really $4,600 out of your pocket. Second, the agency earns commission plus GST on every extra dollar of sale price, so part of any uplift is not yours. The calculator handles both, and it uses the marginal commission rate, which on a tiered agreement is the lower balance rate rather than the headline rate. It also shows the amount you lose if the property does not sell at all, because marketing, unlike commission, is payable either way. Everything updates instantly as you type. Figures are indicative planning estimates, not quotes, so use your own agency marketing schedule.

Estimates only. Commission structures are indicative unless flagged otherwise, every rate in New Zealand is negotiable, and no marketing spend can be guaranteed to lift a price. This is not legal, tax or financial advice.
Vendor paid advertising, usually shortened to VPA and sometimes called the marketing schedule, is the money you pay to promote your own property. It is a separate line from commission and is invoiced separately, often before the listing goes live. A typical schedule covers professional photography, a floor plan, listings on the major property portals, a signboard and social media, then optional upgrades: video or drone footage, premium portal placement, brochures, print advertising and sometimes staging. The gap between the basic and premium options is what this calculator is about.
Commission is contingent. Marketing is not. If the property does not sell you owe no commission, but you still owe every dollar of the marketing schedule you signed. The Real Estate Authority's consumer site puts it without hedging: advertising expenses generally have to be paid up front, and they have to be paid even if your property does not sell. The agency's downside on a failed campaign is their time. Yours is cash, gone, with the house still yours. That is why this page shows the extra at risk beside the break-even uplift: one is the prize, the other is the stake. Deferred payment schemes that defer the invoice to settlement help cash flow, but they do not change who owes the money and usually carry a fee.
Two things sit between an extra dollar of sale price and your pocket. The first is GST. Marketing is a standard taxable supply, schedules are usually quoted GST-exclusive like commission, and a homeowner is not GST registered, so the 15% is a real and unrecoverable cost: a package $4,000 dearer is $4,600 dearer in practice. The second is commission, which the agency earns on the whole sale price including any part the extra marketing produced, with GST on top. So if you need $4,600 of net benefit and the agency takes 3.335% of the uplift (2.9% plus GST), the uplift has to be $4,758.70 before you are square. The formula is the extra cost including GST divided by one minus the marginal commission rate including GST.
This is where most back-of-the-envelope attempts go wrong. NZ tiered structures charge a high rate on the first slice of the price and a lower rate above it, for example 3.95% on the first $400,000 then 2% on the balance, plus GST. Your average rate on a $770,000 sale might be 2.9%, but the rate on an extra $5,000 is 2%, because that money sits in the balance tier. The headline rate overstates the hurdle.
The other structures behave differently again. A percentage-with-minimum agency charges nothing extra while its minimum fee is still binding, so below the crossover price the whole uplift is yours. A fixed-fee agency charges the same amount anywhere inside a price band, so the marginal rate is zero within a band but crossing into the next can cost thousands at once. Above the top published band the fee is negotiated individually, so this page says so rather than inventing a number.
Priya and Sam are selling in Tauranga and expect $850,000. Their agency agreement is a common tiered structure: 3.95% on the first $400,000 then 2% on the balance, plus GST. The schedule offers Essentials at $1,950 plus GST and a Premium auction campaign at $6,450 plus GST.
The difference between the packages is $6,450 less $1,950 = $4,500 plus GST. Adding 15% GST, the extra they actually pay is $4,500 × 1.15 = $5,175.00. Because $850,000 is well above the $400,000 tier cap, every extra dollar of sale price attracts commission at 2%, and GST makes that 2.3%. So the uplift needed is $5,175.00 divided by (1 minus 0.023), which is $5,175.00 ÷ 0.977 = $5,296.83. Checking it: commission on $5,296.83 at 2% is $105.94, GST on that is $15.89, and $5,296.83 less $121.83 leaves exactly $5,175.00. The uplift is 0.62% of $850,000, so their break-even sale price is $855,296.83.
Now the other side. Premium costs $6,450 × 1.15 = $7,417.50 and Essentials costs $1,950 × 1.15 = $2,242.50, so if the property does not sell Premium has cost them $5,175.00 more for the same outcome. Their real question is whether the video, print run and portal upgrade reach enough extra serious buyers to move the price by more than $5,296.83, weighed against that $5,175.00 downside. On $850,000 a 0.62% uplift is a low bar. On a $450,000 property the same $4,500 spend difference needs a 1.18% uplift, a materially harder ask.
No New Zealand data set proves a reliable dollar return per dollar of vendor advertising, and any agent who promises one is overselling. What extra spend buys is reach, and reach matters because price is set by competition between buyers. One extra bidder can be worth more than the whole campaign. Zero extra buyers makes it a pure cost.
A few items do most of the work. Professional photography is close to non-negotiable, because almost every buyer meets your property as a thumbnail, and the two main portals carry the bulk of buyer traffic. Beyond that it depends on the property: video earns its keep where the setting is the selling point. Ask which buyers each line item reaches that the basic package would miss.
The schedule is part of the agency agreement, and the agreement is negotiable. Settled.govt.nz is explicit that you usually pay extra for marketing but you do not have to pay extra if you do not want to. Ask for the plan in writing with an itemised budget so you can see each line, then delete what you cannot justify. Ask whether the agency or salesperson will contribute, which is common when they are competing for a listing, and ask in writing what happens if the property is withdrawn early. If you have signed a sole agency agreement and changed your mind, section 130 of the Real Estate Agents Act 2008 lets you cancel in writing by 5pm on the first working day after you are given your copy.
This is for anyone in New Zealand who has been handed a marketing schedule and has to choose between the options on it: first-time sellers who have never seen a VPA quote, owners comparing agency pitches, sellers in a slower market where the risk of no sale is real, and trustees and executors who must justify the spend. It also works in reverse, to test whether the cheapest package is a false economy.
