1. The formula
Every brand manager who buys creator ads uses roughly this formula, even when they pretend to be more sophisticated:
base_rate = (followers / 10,000) × platform_rate × ER_multiplier × niche_multiplier
That's it. Their 'audience fit analysis' and 'brand alignment scoring' are usually sanity checks stacked on top of this, not replacements for it. Knowing the formula gives you leverage because you can see what they're doing.
2. The four multipliers
Platform rate per 10K followers: - Instagram: $100 - TikTok: $80 (higher reach but lower purchase intent) - YouTube: $250 (dedicated video, permanent search value)
ER multiplier: - ER ≥ 5%: multiply by 2.0 - ER 3–5%: multiply by 1.5 - ER 1.5–3%: multiply by 1.1 - ER < 1.5%: multiply by 0.8
Niche multiplier: - Premium (finance, B2B, tech, luxury): 2.5× - High value (beauty, fitness, parenting): 1.6× - Standard (food, travel, lifestyle): 1.0× - Lower tier (entertainment, memes): 0.7×
Apply them in order. A 50K Instagram account with 4% ER in the fitness niche: (50,000/10,000) × $100 × 1.5 × 1.6 = $1,200 per post.
3. Line items creators forget
The base rate covers one post on your account. Everything else is an add-on:
- Usage rights (brand repurposes content in their own ads): +30–60%
- Exclusivity (you can't work with competitors for X months): +50–100%
- Whitelisting (brand runs paid ads using your account): +50%
- Rush turnaround (under 7 days): +25%
- Revisions beyond 2 rounds: +15% per extra round
Most creators forget to bill these and leave $200–$2,000 on the table per deal. Brands will pay these line items without pushback — they're priced into the media budget already.
4. How to negotiate up from a lowball offer
When a brand sends a lowball offer, send this one-line reply: 'Happy to partner — my rate for this scope is $X, and I can start within Y days.'
Don't justify. Don't apologize. Don't counter yourself lower. Don't list your case studies. Just state the number and the delivery window.
Seventy percent of the time they accept. Twenty percent of the time they counter upward from their original offer. Ten percent they walk away — and those ten percent were never going to be profitable deals anyway. The worst outcome is worth losing.
