Creator Economy Calculators & Tools

Free, practical calculators for creators and the brands who work with them — measure engagement, estimate a fair rate, work out CPM, project follower growth, calculate campaign ROI, and estimate ad-revenue earnings.

Engagement Rate Calculator

Calculate engagement rate from likes, comments, shares, and saves — by follower count or by reach, with notes on what counts as healthy per platform.

Influencer Rate Calculator

Get a suggested sponsored-post rate from follower count, engagement rate, platform, and content format — an estimate to negotiate around, not a quote.

CPM Calculator

Solve for CPM, total campaign cost, or impressions — enter any two of the three and get the third, plus cost per single impression.

Follower Growth Calculator

Project your follower count forward from a monthly growth rate or typical monthly gain, with a month-by-month compounding table.

Campaign ROI Calculator

Calculate ROI% and ROAS from spend and revenue, or from conversions and revenue per conversion, plus cost per conversion.

Creator Earnings Estimator

Estimate ad-revenue-style earnings from views and platform RPM — a low/mid/high range, or a single figure if you enter your own RPM.
