Average Order Frequency
CRM & RetentionAlso: Purchase Frequency · AOF
Quick definition
Average order frequency is how many times the typical customer buys from you within a set period, usually a year. It's calculated by dividing total orders by the number of unique customers who placed them. It's one of the three inputs used to build lifetime value.
Frequency below 2 over a 12-month window suggests most customers aren't returning. Above 4 usually signals a consumable or subscription-style purchase pattern.
How it varies across Australia
Average order frequency varies enormously by category. Australian consumables and grocery-adjacent brands sit well above apparel or homewares, where repeat purchase cycles stretch out over months. Subscription and consumable businesses should expect a much higher frequency than considered-purchase categories.

Average order frequency answers a simple question with a lot riding on it. How often does someone who buys from you, buy from you again? It's total orders divided by unique customers across a chosen window, usually a year.
The number matters because it's one of the three levers behind lifetime value (LTV), alongside average order value (AOV) and customer lifespan. A business can grow revenue by raising prices, acquiring more customers, or getting existing customers to come back more often. The third lever is usually the cheapest and the most neglected.
Frequency is also a leading indicator of churn. A customer whose order frequency is slowing down is a customer drifting toward churn, often before they've formally stopped buying. Retention teams that only watch churn rate are watching the outcome. Frequency is the earlier signal.
The number gets distorted easily. A flood of new customers with only one order each drags the average down even if your loyal base is buying more often than ever. Segment by cohort before drawing conclusions.
A rising average order value with a flat order frequency is a business quietly leaning on fewer, bigger transactions instead of a stronger relationship.
How to calculate it
Average Order Frequency = Total orders ÷ Number of unique customers
Worked example. Your store processed 3,600 orders last year from 1,200 unique customers. Average order frequency = 3,600 ÷ 1,200 = 3. The typical customer bought three times in the year.
The Australian context
Australian ecommerce is smaller and more price-sensitive than the US market, so acquisition costs are less forgiving. A business that can't lift order frequency has to keep feeding the top of the funnel to grow, which is expensive given the tighter media market. Retention-led growth is a bigger lever here than in larger markets where fresh customers are cheaper to find.

Common questions
What's a good average order frequency?
It depends entirely on your category and typical purchase cycle. Consumables and low-cost items should see higher frequency than considered purchases like furniture or electronics. Compare against your own historical trend and category norms rather than a generic figure.
How is average order frequency different from retention rate?
Retention rate measures whether a customer comes back at all within a period. Average order frequency measures how many times they buy once they're active. A business can have strong retention but low frequency if customers stick around but buy rarely.
How often should I measure average order frequency?
Quarterly reviews with a rolling 12-month window work well for most businesses. Shorter windows are noisy for low-frequency categories. Always segment by acquisition cohort so new customer influx doesn't distort the trend.
Can I improve average order frequency without discounting?
Yes. Replenishment reminders, loyalty programmes, better post-purchase email sequences and product bundling all lift frequency without training customers to wait for a sale. Discounting is the fastest lever and usually the most damaging to margin long term.
