How these social-media tools work
Everything here is transparent arithmetic on numbers you supply: engagement rate as interactions divided by reach or followers, watch-time math from views and duration, earnings estimates from your CPM or rate inputs. Nothing is fetched from any platform, and no account is connected, which is why the numbers stay private and the tools work offline.
The formulas are printed on each page. When platforms define a metric differently (engagement over reach versus over followers), the tool labels which convention it uses so cross-platform comparisons stay honest.
Choosing a tool
Use the engagement calculator for post-level analysis, watch-time tools for video pacing decisions, and earnings estimators for rate negotiation. Comparing creators: run the same metric with the same denominator for both, or the comparison is noise.
Honest limits
Earnings estimates are only as good as the rate you enter; platform payouts vary by region, season, and format, and no estimator can know your specific deal. Treat outputs as negotiation prep, not income predictions.
