Engagement rate

This calculator sums the interaction metrics you entered and divides by your follower count, following the formula below.

Formula: (likes + replies + reposts + quotes) / followers × 100

How it works

Enter likes, replies, reposts and quotes for a post — or several posts in batch mode.
Add your follower count so the rate has a denominator.
Read the result: total interactions, engagement rate and the exact formula used.

What the calculator does

Documented formula

ER = (likes + replies + reposts + quotes) / followers × 100 — shown right next to your result, driven by a versioned formula config.

Batch mode

Enter up to 12 posts and get averages per metric plus the mean engagement rate across them.

Interaction breakdown

A proportional bar shows which interaction type carries your engagement.

Honest about gaps

Metrics you leave empty are excluded and listed — we never guess numbers.

Reading your number

Engagement rate on Threads is usually compared per-follower; two accounts with equal interactions differ wildly in ER at different follower sizes.
Replies weigh more for reach than likes — watch the breakdown, not just the total.
Calculate several posts before drawing conclusions; single-post ER is noisy.

FAQ

What is a good Threads engagement rate?

It depends on follower size and niche. Accounts under 10k followers often see 1–5%; larger accounts trend lower. Compare against your own history rather than a global number.

What formula does this calculator use?

ER = (likes + replies + reposts + quotes) / followers × 100. The formula lives in versioned configuration and is displayed with your result.

Why is my rate null?

Without a follower count there is no denominator, so no rate can be computed — the total interactions still show.

Can I average multiple posts?

Yes — batch mode averages each metric across posts and reports the mean engagement rate.

Do you store my numbers?

No. The math runs entirely in your browser.
