CPM Calculator: What do organic Reddit and X impressions cost?
What does brand awareness actually cost in your category?
Pick your product category to see typical paid social CPMs (Reddit Ads, X Ads, Meta), then see how many more impressions the same budget buys you through organic Reddit and X threads. We bill a flat $1 per 1,000 impressions delivered, plus $50 per 1,000 site visits attributed back to our threads.
How the math works
Paid social charges you per 1,000 impressions through an ad auction. Reddit Ads typically clear $3 to $10 CPM, X Ads $2 to $6, and Meta $2.50 to $15, with premium buyer-intent placements sitting at the top of those ranges. The calculator shows a category-typical paid CPM so you are comparing against what a B2C brand actually pays to reach its audience, not the cheapest broad-reach inventory.
S4L delivers impressions a different way: we seed your brand into Reddit and X threads where your buyers are already reading, and meter the views those posts earn at a flat $1 per 1,000 impressions. No ad auction, no media cut, so the same budget buys several times the reach. When a reader clicks through to your site, that attributed visit bills separately at $50 per 1,000 visits, reconciled against your own analytics so you only pay for traffic that actually landed.
The impression multiplier in the calculator is simply your category's paid CPM divided by ours. It is the ceiling for a given budget: we invoice only for impressions and visits actually counted, never for posts sent, so you never pay for views that did not happen.

They are blended 2025 to 2026 averages from public ad-platform benchmarks: Reddit Ads typically run $3 to $10 per 1,000 impressions, X Ads $2 to $6, and Meta $2.50 to $15 depending on category and placement. We use the higher end of premium-placement CPMs per category because that is what a B2C brand actually pays to reach a buyer audience, not the cheapest broad-reach inventory. The calculator shows a category-typical paid CPM so you can compare like for like, not a cherry-picked best case.
There is no ad auction and no media buy. We seed your brand into Reddit and X threads where your buyers are already reading and asking questions, so the impression is the conversation itself, not a bought placement on top of it. You are paying for our agent and operators to find the right threads and write contextual replies, metered against the views those posts actually earn. No platform takes an ad cut, which is why the delivered CPM lands near $1 instead of $5 to $12.
It is just the two CPMs divided. If your category's paid CPM is $8 and ours is $1, the same budget buys roughly 8x the impressions on paper. The honest caveat: organic threads ramp over the first couple of weeks as we tune voice and find the right communities, and not every thread performs. We invoice only for impressions actually counted, so the multiplier you see is the ceiling for a given budget, and you never pay for views that did not happen.
Three reasons the calculator accounts for. Ad blockers and banner blindness drop 30 to 40% of paid impressions before they register; an in-thread reply renders for everyone reading the conversation. Readers process a contextual comment as a peer recommendation rather than a 'Sponsored' placement, so per-impression trust is higher. And top Reddit and X threads stay indexed and re-read for months, so the reach compounds long after a paid campaign's budget runs out.
Impressions are top-of-funnel brand awareness. When a reader clicks an outbound link in one of our threads and lands on your site, that is a higher-confidence delivery, so it bills separately at $50 per 1,000 attributed visits. Every link is tagged with a unique tracking parameter and reconciled against your own analytics (PostHog, GA4, whatever you run), so you only pay for visits that actually arrived. The calculator estimates this using a typical 2% organic click-through rate.
No setup fee, no retainer, no annual contract, no minimum monthly spend. You pay the metered $1 per 1,000 impressions and $50 per 1,000 visits, invoiced monthly for what was counted, and you can pause or scale any month. The real constraint is fit: this is for established B2C products with a brand-awareness budget, not pre-PMF projects or agencies reselling the work.
