Brands slide into your DMs with an offer, and you're left guessing whether it's fair. Sponsored-post rates aren't published anywhere official — there's no rate card, no government table, no platform-set price — so most creators either lowball themselves out of nerves or pull a number out of thin air. This calculator gives you a rough, defensible negotiating anchor built from your follower count, engagement rate, and platform, so you walk into the conversation with a number grounded in your own numbers instead of a guess.
How it works
The starting point is a per-1,000-follower base rate for each platform: $10 for Instagram, $8 for TikTok, $20 for YouTube. These are rough industry ballparks, not fixed prices — they roughly track how much production effort and sustained attention a sponsored post on that platform typically demands, with a long-form YouTube integration sitting at the high end and a single Instagram feed post at the low end.
That base rate gets multiplied by your engagement rate, because reach without attention isn't worth much to a brand. The calculator treats a 3% engagement rate as the "average" anchor and scales the base rate up or down around it: divide your engagement rate by 3 to get a multiplier, then clamp that multiplier between 0.5x and 2x so an unusually low or viral-high engagement rate doesn't send the estimate to an unreasonable extreme. The result is a mid estimate, and the calculator brackets it with a low (70% of mid) and a high (140% of mid) to show the realistic spread rather than pretending there's one right number.
Worked example
Take a creator with 50,000 Instagram followers and a 3% engagement rate — right at the "average" anchor.
- Base rate: (50,000 ÷ 1,000) × $10 = $500
- Engagement factor: 3% ÷ 3% = 1.0 (no adjustment, since this is the average case)
- Mid estimate: $500 × 1.0 = $500
- Low estimate: $500 × 0.7 = $350
- High estimate: $500 × 1.4 = $700
So that creator's negotiating range runs $350 to $700, centered on a $500 mid estimate. Push the engagement rate up to 6% and the factor doubles to 2.0, pushing the mid estimate to $1,000 — engagement matters as much as raw follower count in this formula, sometimes more.
How to interpret your result
This is a floor for a conversation, not a ceiling and not a quote. Real sponsored-post rates swing on factors this calculator has no way to see: your specific niche (finance and B2B audiences typically command more than general lifestyle content), exactly what the brand wants delivered (one static post versus a full content package with stories, a reel, and usage rights), whether they want exclusivity against competing brands, whether they want to whitelist your content for their own paid ads, and how well your specific audience actually converts for that specific advertiser.
If a brand's opening offer lands below your low estimate, that's a reasonable signal to push back. If it lands well above your high estimate, don't assume you're being lowballed elsewhere — some brands simply pay more for a creator's specific fit, audience quality, or track record than any formula captures. Use this number to anchor the negotiation, then let the specifics of the deal move you up or down from there.
Methodology & sources
The formula is base = (followers / 1,000) × platform base rate, where the platform base rate is $10 (Instagram), $8 (TikTok), or $20 (YouTube) per 1,000 followers. That base is then scaled by an engagementFactor = clamp(engagement rate / 3, 0.5, 2), treating a 3% engagement rate as the average case, to produce mid = base × engagementFactor. The low and high estimates are mid × 0.7 and mid × 1.4 respectively, giving a spread around the central figure instead of a single number.
The per-1,000-follower base rates are deliberately rough — no platform publishes an official sponsored-post rate card, so these figures are compiled from publicly discussed industry ballparks such as those summarized in Influencer Marketing Hub's influencer rate guide. Actual rates reported by creators and agencies vary enormously around these anchors depending on niche, deliverables, and audience quality, which is exactly why this tool reports a range and calls it an anchor rather than a price. And whatever rate you land on, remember that sponsored content still has to be disclosed under the FTC's endorsement guidelines — that obligation doesn't change based on what you're paid.
