At a glance
Mercari Health Score is a single 0-100 read on how healthy your seller account looks to the marketplace, blending rating, ship time, returns, disputes, and listing compliance. When it dips below the safe band, your standing and visibility are at risk.
Calculation
Vortex IQ combines several account signals into one weighted index on a 0-100 scale. The inputs are your seller rating, ship-time performance such as the share of orders sent within the promised window, your return and dispute rates, and listing-compliance signals. Each input is normalised and weighted so that no single factor dominates, then summed to the headline score. Because it blends a near-real-time view with a 7-day trend, a sharp single-day move and a slow weekly slide both surface here.Worked example
A representative reading of Mercari Health Score for a typical Mercari reseller. Suppose a seller who usually sits around 88 drops to 66, tripping the<70 alert. Unpacking the inputs shows ship time slipped because two orders went out late during a busy week, and one dispute is open. None of those alone would feel urgent, but together they pulled the composite below the safe band, where Mercari can quietly reduce visibility. The action is to clear the late-shipping backlog, resolve the open dispute promptly, and protect the seller rating. Cross-reference mer_ships_within_3_days_rate for the shipping driver, mer_dispute_rate for the dispute driver, and mer_avg_review_rating for the rating driver. Vortex Mind traces the upstream causes that moved the score, and Ask Viq answers plain-English questions like “what pulled my health score below 70 this week?”

Reconciling against Mercari
Where to look in Mercari’s own dashboard: Mercari does not publish a single health number, but it surfaces the underlying pieces in your seller profile and ratings: your star rating, badges such as Fast Shipper, and any policy or shipping flags. This card synthesises those signals into one trackable index. Why the Vortex IQ value may legitimately differ:
Cross-connector reconciliation: Each marketplace defines account health differently, so treat this score as Mercari-specific rather than comparable across connectors. For divergence investigations, use Vortex Mind.
