Average Order Value (AOV) Calculator
Average order value, or AOV, is one of the simplest yet most powerful numbers for any shop, cafe, online store or service business to track. This calculator works out your AOV by dividing total sales revenue by the number of orders or transactions over a chosen period, giving you the average amount each customer spends per purchase. You enter your total revenue in New Zealand dollars and the number of orders, and the tool returns the average spend per order along with a quick view of how each order contributes to your top line. Retailers, ecommerce operators, hospitality owners and marketers all use AOV to understand basket size, judge the effect of pricing changes, bundles and free shipping thresholds, and decide where to focus growth. A rising AOV often means upselling, cross selling or premium ranges are working, while a falling AOV can signal discounting that erodes margin. AOV also pairs neatly with traffic and conversion data, because lifting the average spend is usually cheaper than buying more visitors. To get the most from it, measure AOV over a consistent window such as a month or a quarter so seasonal swings do not distort the picture, and segment it by channel, campaign or customer type to see what truly drives spend. Try nudging AOV upward with thoughtful bundles, volume offers, add on suggestions at checkout and minimum spend rewards, then compare before and after. Track the trend rather than chasing a single figure, and always read AOV alongside margin so that higher order values genuinely add profit rather than just revenue.
AOV = total revenue / number of orders. Estimate only, not financial or tax advice.
How it works
Average order value is total revenue divided by the number of orders over the same period. The result is the average amount spent per order. Keep both figures on the same GST basis and time window.
Worked example
With total revenue of $48,500 across 620 orders, you divide 48,500 by 620 to get $78.23. That is the average spend per order.
