Promo ROI calculator
Before you buy the shoutout: reach, click-through, conversion and spend in — cost per new subscriber and the real return out, after the platform fee.
✓ Free, no signup ✓ 20% platform fee included ✓ Works for Fansly too
This promo pays for itself at roughly 476% return on spend — if the lifetime revenue guess holds.
A worked example: the $50 shoutout
A shoutout reaching 10,000 people at a 2% click-through sends 200 visitors. At a 3% visitor-to-subscriber conversion, that is 6 new subs. If a subscriber is worth $60 to you over their stay, that is $360 gross, $288 after the platform fee, $238 after the $50 promo — and $8.33 per subscriber gained. The same $50 with half the conversion barely breaks even, which is why the landing page decides more than the promo does.

Frequently asked
- What does a shoutout or promo usually cost?
- Anywhere from a few dollars for a small cross-promo to hundreds for a large account, which is exactly why a flat answer is useless. The number that matters is cost per subscriber gained, and that is what this calculator isolates.
- What is a good cost per subscriber?
- Compare it against what a subscriber is worth to you over their whole stay — subscription months plus tips and PPV. If a sub is worth $60 lifetime and the promo delivers subs at $8, it pays for itself many times over; at $70 per sub it never will.
- Why did my promo get clicks but no subscribers?
- Click-through proves the audience matched the promo; conversion proves the page matched the visitor. Clicks without subs usually means the page they landed on — price, pinned content, bio — lost them, not the promo itself.
- Does this work for paid ads too?
- Yes. Reach, click-through and spend map directly. The platforms most creators buy promo on are other creators’ pages, but the arithmetic is identical for any traffic source.
