Streamers often look at agency commission and think "15 percent is too high." That intuition is backwards. Here is the math that shows why.

Assume the streamer is currently earning $10,000 per month solo. The agency charges 15 percent of managed revenue. The agency adds 30 percent in incremental revenue through brand deals, merch, and platform negotiation that the streamer would not have closed alone.

The math: $10,000 baseline + $3,000 incremental = $13,000 total managed revenue. Agency commission at 15 percent = $1,950. Streamer net = $11,050.

The streamer earns $1,050 more per month after paying agency commission than they would have earned solo. That is a 10.5 percent net lift on their previous income, after fees, every month, every year, for as long as the relationship runs.

At mid-tier and Pro-stage, that delta runs $2,000 to $15,000 per month. At higher tiers, the delta crosses six figures annually. That is the math that makes agency commission rational. The agency only wins when the streamer wins by more than the commission.

If an agency cannot add at least 30 percent in incremental income, the math fails and the relationship is not worth signing. That is the test you run before any signature.
