Influencer Rate Calculator: Estimate a Fair Sponsorship Price

There is no official price list for a sponsored post, but there is a defensible starting point: audience size adjusted for how engaged that audience actually is. This calculator uses a simple, fully editable formula, follower count times a base rate per 1,000 followers, scaled by how your engagement compares to a platform benchmark, so you always know exactly why it landed on the number it did.

How the influencer rate formula works

The suggested rate is your followers divided by 1,000, multiplied by a base rate per 1,000 followers, multiplied by an engagement multiplier. The multiplier compares your actual engagement rate to a platform benchmark: if your engagement is twice the benchmark, the multiplier is 2x and the suggested rate doubles. If it is half the benchmark, the rate is cut in half.

An account with 50,000 followers, a 3% engagement rate against a 1.5% benchmark, and a $10 base rate per 1,000 followers lands at a $1,000 suggested rate, with a typical negotiated range of $700 to $1,300 either side of that midpoint.

Why engagement rate matters more than follower count

Two accounts with identical follower counts can be worth very different amounts if one has an audience that actively likes, comments and shares while the other has gone quiet. Brands increasingly price around engagement because it is a better predictor of whether a sponsored post will actually get seen and acted on, not just counted as an impression.

Adjusting the calculator for your own niche

The base rate and benchmark engagement rate are starting assumptions, not fixed facts, which is why both fields are editable. High-trust niches like finance or B2B software often support a higher base rate despite smaller audiences, while broad entertainment niches often see lower base rates but much larger reach. Adjust both numbers to whatever you have actually seen quoted or paid in your specific category before you treat the output as your asking price.
