Is your 15% surcharge the right number?

A public holiday costs you more to open than a normal day, and the surcharge is how hospitality tries to claw that back. Two legal costs drive it.

First, time and a half. Every hour your staff work on a public holiday is paid at one and a half times their normal rate. The extra half is a real added cost you do not carry on an ordinary Tuesday. Second, the alternative holiday. If a staff member works a public holiday that is a day they would normally work, they also earn a full paid day off to take later. That is a future cost, easy to forget, and it is genuine. Our public holiday pay calculator works out both for a single employee. Add rent and power that run whether you open or not, and thin holiday trade, and you can see why a cafe that opens on Waitangi Day wants something back at the till.

Most places pick 15% because the place down the road charges 15%. It is a habit, not a calculation, and it can be wrong in either direction.

Here is the actual sum. Take your extra cost for the day: the time-and-a-half premium on the hours worked, plus the value of the alternative holidays earned. Divide that by the takings you expect for the day. That percentage is your true break-even surcharge. A small cafe with four staff on and a quiet holiday might need more than 15% just to break even, because the wage premium is fixed but the takings are light. A busy place turning big volume on the same staff might fully recover its extra cost at 8% or 10%, so 15% quietly pads the margin. The calculator above does this division for you. Copying 15% blind means you are either eating a loss on the day or charging more than your costs justify, and the second one is the one that gets you a complaint.

Surcharges are legal. The Commerce Commission is clear on that. What the Fair Trading Act requires is that a surcharge is disclosed clearly and upfront, so a customer knows about it before they decide to buy, and that the reason is described accurately and does not mislead.

In practice that means a few simple habits:

• Put it where people see it before they order: a sign at the door and counter, a line on the menu, a note on your online ordering.
• State the number and the reason plainly. A 15% surcharge applies today, being a public holiday.
• Show it as its own line on the receipt, not buried in the prices.
• Only charge it on the days you actually carry the extra cost. A surcharge on a normal day, or one dressed up as a public holiday charge when it is not, is exactly what the Commission warns against.

Get the disclosure right and a surcharge is a non-event. Spring it on people at the till and you turn a fair cost recovery into a bad review. The penalty side is real too: Fair Trading Act breaches can run to fines of up to $600,000 for a company.

A surcharge is not the only way to handle a public holiday, and it is not free of cost even when it is legal and well disclosed. Some customers accept it without a thought. Others notice, and a handful resent it, especially if it feels higher than the day warrants or turns up as a surprise. That is the trade-off: you recover a real cost, but you spend a little goodwill doing it.

Weigh the options honestly. You can surcharge, and if you do, set it at your real break-even and disclose it well. You can absorb the cost and treat the day as a loss leader that keeps regulars happy and staff earning. You can open on a limited menu with a lighter roster, so the wage premium is smaller and you may not need a surcharge at all. Or you can simply close, which plenty of good operators do, and which costs you a day's trade but no goodwill. There is no single right answer. The point of the number this tool gives you is that whichever path you pick, you are choosing it with the real cost in front of you rather than guessing.
