Instagram handouts more numbers than ever, but engagement rate is the one that predicts whether the algorithm will favour you. This tool computes it the way creators actually should.
Why reach beats followers here
A post that goes to 20% of your followers at 5% ER is performing better than the same content (by ER) going to 100% at 1%. Reach-normalised ER is the fairest comparison between posts.
The save as a vote
Saves correlate with subsequent reach more than likes do, which is why weighting them makes your ER a truer predictor of distribution — and a sharper editing tool for your content strategy.
Frequently asked questions
By reach, 1–4% is typical; above 7% is outstanding. Reels often show higher ER numbers because of inflated reach, so compare formats within your own account.
Saves are the algorithm's strongest positive signal for distribution — a save means a user intends to return, which pushes your content to more people.
Use reach. Followers who never see the post shouldn't dilute the numerator's denominator — reach reflects who actually encountered the content.
