The 2026 distribution signals penalize external links in the body of your text. Move the controls: you'll see the real cost in 30 seconds.
🔒 The entire calculation runs in your browser — nothing is sent to any server (open DevTools and verify)1 · Link penalty: we apply a 0.70 factor — the top of the −55%…−70% range found in public 2025-26 distribution reports — to posts with a link in the body. It's an editable assumption: if you believe it's −50%, the result changes linearly.
2 · Estimated "clean" reach: your average impressions R mix posts with and without links. We solve for the average of an unpenalized post: clean = R / (1 − 0.7·p), where p = fraction of linked posts.
3 · Monthly loss: lost = posts × p × clean × 0.7. Lost visits use your v/1000 ratio. None of this is a promise: it's arithmetic on your inputs with one published factor — if someone sells you "+900% guaranteed reach", open the Network tab… and run.
