Effective starting this week, Billboard is implementing a new formula for streaming on the Billboard 200 and Billboard Hot 100.
Backgrounder
Billboard 200 is computed based on sales and streams. As 1 track sale and 1 stream doesn’t generate the same revenue as 1 traditional album sale, Billboard introduced Equivalent Album Units (EAU).
Billboard 200 formula: EAU = digital/physical album sale + Track Equivalent Album (TEA; 10 track sales) + Streaming Equivalent Album (SEA; 1K premium streams = 2.5K free streams).
For SEA, there are two (2) tiers. Tier 1 is Premium Streams, or those audio/video streams from paid/subscription/free trial accounts. Tier 2 is Free Streams, or those audio/video streams from non-subscription/non-premium/ad-supported accounts. Basically, if you’re not paying for a subscription and are not using a free trial, then your streams fall under Tier 2.
What changed?
This 2026, Billboard is increasing the weight of streaming, and further adding weight to free streams. In the old formula, it takes 1,250 premium streams or 3,750 free streams (1:3) to equate an album. Now, it only takes 1,000 premium streams or 2,500 free streams (1:2.5) to equate an album unit. This means it will now take 33.3% fewer non-premium streams and 20% fewer premium streams to equal an album unit on Billboard 200.
Billboard Hot 100 will also now follow the 1:2.5 premium to free streams weighting ratio, from the previous formula where premium streams count as full, while free streams count two-thirds of a premium.
How will the new formula impact Stray Kids album units?
If we apply the new formula to the Stray Kids albums that debuted on Billboard 200, they will have 1K to 4K increase in Streaming Units, i.e, KARMA would’ve debuted with 317K total units instead of 313K, and DO IT would’ve debuted with 298K instead of 295K.
HOWEVER, it’s important to consider the caveat:
While the new formula will increase the overall figures for all albums on the Billboard 200, it favors streaming-heavy artists and is somewhat disadvantageous for the majority of K-pop artists, as they largely rely on pure album sales—especially from Week 2 onward. No K-pop artist has achieved over 100K debut units from streaming alone, and even when recomputing all previous K-pop albums using the new formula, no pre-2026 K-pop album would surpass 65K streaming units.
For first-week sales, the new rules will not make a significant difference, though they could make or break a No. 1 debut when the gap with No. 2 is small. From Week 2 onward, as pure sales naturally decline, the new rules are more likely to push K-pop albums down the chart in favor of streaming-heavy artists.
Importance of Premium/Free Trial streaming
BUT, even if the new rules favor streaming-heavy artists, they present an opportunity for fans to adapt to the evolving landscape of music consumption. This also underscores the importance of using PREMIUM/FREE TRIAL streaming, as these carry full weight on Billboard, thereby improving overall album and single units.
