How much should you charge per post?
This calculator estimates what to charge for a sponsored post from four inputs: follower count, average engagement rate, platform, and content type. It returns a headline rate plus a low-to-high negotiation band (70% to 150% of the headline) and the implied rate per 1,000 followers (RPM) — the metric brands use to compare creators.
The model is transparent: rate = (followers ÷ 10,000) × base rate per 10k × content-type multiplier × engagement multiplier. Base rates per 10,000 followers are $100 for Instagram, $200 for TikTok, $500 for YouTube, and $80 for X/Twitter. The engagement multiplier is 1 + 0.15 × (engagement% − 3), floored at 0.5 — so 3% engagement is neutral, every point above adds 15%, and low engagement discounts the rate.
Content multipliers reflect production effort: Stories are 1×, single feed posts 2.5×, carousels or video posts 4×, Reels/TikTok videos 6×, and full YouTube integrations 8×. A YouTube integration demands scripting, filming, and editing, so it prices at eight times a Story per follower.
Platform base rates mirror typical market rate differences: YouTube commands the highest per-follower pricing because video integrations run long and convert well; X/Twitter posts price lowest. Changing platform with the same audience size and content type moves the estimate several-fold.
The default inputs — 50,000 Instagram followers, 3% engagement (neutral multiplier), single post (2.5×) — compute as (50,000 ÷ 10,000) × $100 × 2.5 × 1.0 = $1,250 per post. The calculator shows a negotiation band of $875–$1,875 (0.7×–1.5×) and an RPM of $25.00.
Raising engagement to 6% adds 3 × 0.15 = 45%: $1,812 headline. Switching the same audience to a Reel (6×) gives $3,000; a YouTube integration (8×) with YouTube's $500/10k base gives $20,000-equivalent inputs — a reminder that the model scales linearly and very large numbers should be sanity-checked against real market data.
| Input | Value | Effect on Rate |
|---|---|---|
| Platform base (per 10k) | $80–$500 | X lowest, YouTube highest |
| Story | 1.0× | Lowest effort format |
| Single post | 2.5× | Standard feed post |
| Carousel / video | 4.0× | Multi-asset production |
| Reel / TikTok | 6.0× | Full video production |
| YouTube integration | 8.0× | Highest production cost |
| Engagement ±1% | ±15% | Floored at 0.5× multiplier |
Market rates are ultimately negotiated. Industry surveys (Influencer Marketing Hub and similar) have reported average costs around $10 per 1,000 Instagram followers and $25 per 1,000 YouTube subscribers for dedicated videos, with wide variance. Engagement rate is the strongest lever: brands increasingly pay for verified audience quality rather than raw follower counts, and creators with 3–6%+ engagement command premiums over the follower-count baseline.
Use this calculator as a starting point for your media kit, then adjust for exclusivity windows, usage rights (how long the brand can reuse your content), whitelisting/paid-boost permissions, and content ownership — each can legitimately add 25–100% to a base rate. Long-term partnerships usually price below single-post rates in exchange for volume.
The low and high figures this calculator shows (70% and 150% of the headline rate) are a negotiation band, not confidence limits. Quote near the high end when a brand approaches you cold, near the middle when you're pitching, and accept near the low end only for long-term contracts or brands you genuinely want to work with repeatedly.
Round your quotes. A rate of $1,250 reads as researched; $1,247 reads as generated. Present the number with your engagement rate and audience demographics — the two data points brands check first — and anchor it to your RPM (rate per 1,000 followers), which the calculator also outputs, so the buyer can compare you fairly against larger and smaller creators.
Watch the common discount asks: exclusivity in your niche, content usage rights beyond 30 days, and whitelisting all add real value and should cost extra. A useful rule from agency practice: permanent usage rights alone often justify +50%, and category exclusivity for 90 days another +25–30%.
How much should I charge for a sponsored post?
A common starting point is roughly $10 per 1,000 followers for an Instagram feed post, adjusted up for strong engagement (this calculator adds 15% per engagement point above 3%) and multiplied by content type. At the defaults — 50k followers, 3% engagement, single post — the estimate is $1,250 with a negotiating band of $875–$1,875.
What is RPM and why do brands care?
RPM is revenue per 1,000 followers — the post rate divided by audience size in thousands. It lets brands compare creators of different sizes on one scale; this calculator shows it alongside the headline rate.
Does engagement rate really change pricing?
Yes. Brands use engagement as a proxy for audience quality. This calculator applies +15% per engagement-rate point above 3% and discounts below it (multiplier floored at 0.5), which mirrors how real negotiations treat dead audiences.
Why is YouTube priced so much higher?
Video integrations require scripting, filming, and editing, run longer, and historically convert better. The model uses $500 per 10,000 followers for YouTube versus $100 for Instagram — in line with industry surveys reporting around $25 per 1,000 subscribers for dedicated videos.
What else should I charge for?
Usage rights, exclusivity, whitelisting, and bundling multiple posts all add cost. Treat this calculator's number as the base content fee before those add-ons, which commonly add 25–100%.
