ARIA Charts Print Their Rulebook but Not What a Stream Is Worth
Finding: the ARIA Charts are a weekly rank of sales-equivalent units from a sample of retailers and services, built under a rulebook that is published, and that rulebook prints no exchange rate between streams and sales. ARIA’s own FAQ adds that “There is no fixed number of sales required to achieve a certain chart position in any given week.” That answers the question “how many streams for number one?”: the rules explain how streams are converted, and the rates are not in them.
This post reads the Code of Practice for the ARIA Charts dated 11 December 2025, which was the version ARIA’s page linked at 27 July 2026, together with ARIA’s Charts Frequently Asked Questions. It doesn’t comment on any artist, label or streaming service, and it doesn’t claim the charts are fair or unfair. After this first mention, “the Code” means that document.
What goes into one chart week
The chart week “runs from commencement of trading Friday through to the end of trading the following Thursday inclusively, but this is subject to change at the discretion of ARIA” (Schedule 6(a)). It’s a Friday-to-Thursday week, not a calendar week.
Data comes from a sample, not from every shop and service. Clause 3.6 describes physical retailers’ point-of-sale data plus digital stores and streaming services, and the list of providers is on ARIA’s website (cl. 3.6(d)). Step 2 sets the deadline: “Except in exceptional circumstances, all files must be received by ARIA no later than 10:30am (AEST) on the Friday after the end of the chart sales week. Files received after that time will not be used in the charts.”
Step 3 is a check. If “an abnormal pattern of sales within a file submission cannot be adequately explained, either the abnormal data or the whole file will be discarded at ARIA’s discretion”. Clause 3.4 is the sentence to keep in mind for everything that follows: “as chart calculations are based on sample data (i.e. not all stores / services across the country) it is important to note that the results published remain an approximation of activity during the relevant period.”
Publication is “currently” 5pm AEST on the Friday, or 4pm for the Australian artist charts (Schedule 6(b)). The FAQ says something different: charts are “usually uploaded … Saturday night at 5pm (Sydney time)”. It also describes weighting “total recorded music sales data” with “separate weighting tables … for albums and singles”. The Code says in Step 4A that only physical album sales are weighted. The Code is the fuller document and carries a date, 11 December 2025, while the FAQ page carries none, so where the two differ a reader should follow the Code.
What counts, and what does not
| Item | Rule | Clause |
|---|---|---|
| Sales | A sale must be paid for and delivered; a pre-order counts when it is dispatched | Sch. 1, “Eligible Sales” |
| Giveaways | Giveaways and promotional copies provided free of charge are ineligible | 6.1 |
| Multiple copies | Several copies bought in one transaction count as one sale, whenever possible | 7.6 |
| Bundles | Count only if priced at a premium and the parts are also sold separately | 6.7 |
| Streams | An eligible stream is one the listener specifically requested; streams a service suggested or introduced do not count unless the listener asked for that recording. Tracks in a playlist the listener started do count | Sch. 1, “Eligible Stream” |
| Video streams | On the one video service the Code names, only official content streamed by logged-in viewers counts | Sch. 1, “Eligible Stream” |
| Streaming Tracks chart only | At most ten streams a day per customer count | Sch. 3 item 22(d) |
| Carry-over | Data cannot be carried from one week to the next | 7.7 |
The table leaves out any rule not listed in the Code’s eligibility sections. The ten-streams-a-day limit is printed for the Streaming Tracks chart only, and nothing here extends it to the Singles Chart.
Two of these rules do most of the work in practice. The first is the multiple-copies rule: ARIA counts one sale from a single transaction “whenever possible”, so a large order doesn’t count as many sales. The second is the stream definition. A stream counts when the listener asked for that recording, which includes tracks in a playlist the listener started, provided the track is played for the Code’s threshold duration. A track a service suggested or introduced on its own doesn’t count unless the listener then asked for that recording. In other words, the Code separates what a person chose from what a service put in front of them.
The part the Code does not print
Step 4A covers weighting. For physical albums, ARIA weights the sample so it represents “as closely as possible, the total Australian physical product retail sales”, using “wholesale sales shipments by major record companies”. Digital sales and streaming “are not subject to this weighting process”. There is one adjustment: where a streaming provider cannot supply a full week’s data in time, its data is “scaled up on a pro-rata basis”.
Step 4B covers streams. Streaming data “is subject to ‘Conversion Factors’ which convert plays into the equivalent value of sales.” The Code adds: “These factors are reviewed quarterly and adjusted as necessary.” From October 2018 there are separate factors for subscription and ad-supported services.
The principle is printed in Schedule 3, item 19(f). Streams are factored in “at a rate periodically determined by ARIA in consultation with the ARIA Finance Committee and ARIA Chart & Marketing Committee based on the relative average income of streams to digital track sales.” ARIA’s news notice of 24 October 2018 said “greater emphasis will now be given to paid subscription streams over free ad-supported streams”, and described the approach as “revenue-reflective and access-based”. It printed no ratio.
So the numbers are not in the Code or in that notice. The Code does not print the factors, and that’s the whole claim here. Nothing in the Code suggests wrongdoing. It’s a published rulebook that stops one step short of the figures an outsider would need to recompute a week. For accreditation, clause 10.11 says ARIA has built a conversion tool for its members that incorporates the relevant conversion factors. The Code does not say the weekly chart uses those figures, and this post does not use or assess that tool.
The split between the two kinds of stream is what matters for the next section. Because subscription and ad-supported streams are converted separately, two tracks with the same number of streams can land on different sales-equivalent totals. The size of that gap depends on rates the Code does not print.
Both sides of the argument have a fair point here. Someone who wants to check a chart will say the rates are the one input that matters most, and that a rulebook without them can’t be audited by an outsider. ARIA’s own principle, set out above, is that the rates follow the relative average income of streams to digital track sales, which moves over time. Both statements are consistent with the Code, and the public documents can’t settle between them.
The Code does print one formula. For an album, the two most-streamed tracks are cut back to the average of the next eight titles, and the combined value of the top ten tracks is divided by ten (Schedule 1, “Stream Equivalent Album”).
A worked example, labelled hypothetical
Take two imaginary tracks and two invented exchange rates: 100 subscription streams to one sale, and 400 ad-supported streams to one sale. These rates are made up for this example. The Code prints none.
| Track | Streams | Calculation | Sales-equivalent units |
|---|---|---|---|
| A | 40,000 subscription plus 40,000 ad-supported | 400 + 100 | 500 |
| B | 80,000 ad-supported only | 80,000 / 400 | 200 |
Both tracks have 80,000 streams. Track A scores 500 and track B scores 200, because the mix of stream types decides the result once the two types are converted at different rates. The example leaves out the real rates, the weekly sample, the weighting and any physical sales.
What the example shows is the mechanism. A stream total on its own doesn’t fix a chart score, and anyone quoting “this many streams equals that many sales” needs to say which kind of stream and which rate they mean.
What the unit scale does publish
The Code is open about what an award is worth in units. The table below sets the public items against the ones the Code does not print. Each public item carries its clause, and nothing has been added to the right-hand column that the Code and the FAQ do not support.
| Public (clause) | Not printed in the Code |
|---|---|
| Chart week and publication time (Sch. 6) | The weekly conversion factors |
| Eligibility of sales and streams (6, 7, Sch. 1) | The weighting tables for physical sales |
| The list of data providers (cl. 3.6(d), on ARIA’s website) | Each provider’s share of the sample |
| Gold and Platinum levels of 35,000 and 70,000 sales-equivalent units for singles and albums, and 7,500 and 15,000 for audiovisual (cl. 10.8) | The number of units at any chart position (“no fixed number”, FAQ); how an outsider would recompute a week |
The unit scale is public and the stream exchange rate is not. A reader can see what an award means in sales-equivalent units, but the Code does not give what is needed to work backwards from a position to a stream count.
Why an old song is still there
One question is why old songs never leave the chart, and one suggested fix is some way to penalise older songs. The critics have a fair point: a chart built from consumption keeps a song high for as long as people keep playing it. The Code’s answer is a rule, not an apology.
A single must be “less than two years old measured from the date on which the Single first enters the top 100” to stay on the Singles Chart. Two years after its debut in the top 100, it becomes eligible for the On Replay Singles Chart instead (Sch. 3, item 19(a) and (g)). The Code sets out the On Replay charts from 1 September 2025 (item 17). A title can leave earlier: if after an initial survey period (currently 15 weeks) it falls below a threshold (currently No. 450) and does not recover within a reasonable period (currently 5 weeks). A re-entry after an absence of at least 10 years needs a top-30 position and lasts “a maximum of 10 weeks” (item 19(h)).
Whether a reader likes the result or not, that’s the rule.
How to read a position
There are three ways to read a position, and each leaves something out.
As a rank of units for one week, it is what the Code supports. This reading leaves out the exchange rate and the sample behind it.
As a count of streams, it is wrong. Streams are converted into sales equivalents, and a position ranks those units. The result is a modelled figure, and the four questions for any headline figure are worth asking of it, as of any number built from a sample and some assumptions.
As a verdict on quality, it claims more than the Code does. The Code says the charts “rank the popularity of recorded music” (cl. 2.1(a)) and says nothing on merit. Any single list that puts things in order also reflects choices about what to count, which is the argument in why a single ranking carries its own choices.
Reading Next Friday’s Chart
When the next chart appears, read the position as a rank for a Friday-to-Thursday week, and look for the Code’s page before you quote a stream figure.
