We estimate reach per format from your recent post performance. At least 1,000 followers required.

Why estimate reach

Followers are who could see a post. Reach is who did.

On Instagram, only a fraction of an audience sees any given post. Estimating reach from real posts gives a far better sense of the impressions a partnership might deliver than the follower count alone.

Reach ≠ followers

Instagram shows posts to a slice of the audience. Reach reflects what actually lands.

Estimate before you pay

Get a realistic impressions range so a fee maps to outcomes, not vanity size.

Live from real posts

Base the estimate on up to three actual posts instead of a flat assumption.

How it works

  1. Add up to three posts

    Paste a few public Instagram posts you want to base the estimate on.

  2. Estimates update live

    The reach range recalculates as you add or change posts.

  3. Read the range

    See the estimated impressions a comparable post could reach.

  4. Plan the spend

    Use the estimate to size a fair fee, then move to vetting.

For marketers & agencies Why Reach Matters More Than Followers Follower count is a vanity metric. Reach tells you how many real people will actually see your campaign. That changes everything about how you evaluate, brief, and pay creators. 🎯 Budget more accurately A macro with 500K followers at 8% reach = 40K accounts. A micro with 80K at 50% reach = 40K accounts, at half the price. Reach is the only fair metric to compare CPM across tiers and formats.

📊 Spot underperformers early A creator with 200K followers and 2% reach rate delivers less than a nano at 25% reach. Without estimating reach before you sign, you’re committing budget blind. Catch it before you commit.

🚀 Know cold vs. warm audience split Reels push ~42% of reach to non-followers. Feed posts reach mostly existing audiences. Knowing this split tells you whether to use a creator for awareness (new eyes) or conversion (warm audience).

FAQ

Frequently asked questions about Instagram reach

How is reach calculated?

From public engagement signals across recent posts: like-to-follower ratio, comment density, and impression patterns shared by Instagram. Directional, not Instagram-Insights-grade - but reliable for triage before outreach.

Why does Instagram show different reach numbers?

Instagram Insights returns the exact reach for the creator's own account but isn't shared publicly. Our estimate uses public signals only - it's within a few percentage points of the creator's own numbers in most cases.
