At a glance
Revenue Over Time plots your gross Mercari sales across the last 90 days as an area chart. It surfaces the trend, the seasonal swings, and the lift you get from re-listing or running a promotion.
| What it counts | Gross sales revenue from completed Mercari orders, charted day by day across a rolling 90-day window. |
| Sample type | Backend API data from Mercari, refreshed on the standard data refresh. |
| Why it matters | A single live number hides direction. This chart shows whether you are growing, plateauing, or sliding, and lets you tie revenue moves to specific actions like a price drop or a re-list. |
| Reading the value | Read the shape, not a single point. A rising slope is healthy; flat or falling stretches are cues to refresh listings or adjust pricing. |

Calculation
Vortex IQ buckets the gross sale value of completed Mercari orders by day and renders the series as an area chart spanning the trailing 90 days. The figure is gross revenue before Mercari’s selling and payment-processing fees, so it tracks top-line sales rather than net payout. Days with no sales appear as zero points, keeping the trend line continuous.Worked example
A representative reading of Revenue Over Time for a typical Mercari reseller. A trading-card seller reviews the chart on 20 Jun 26 and sees revenue hovering around 90 a day after a 25 May 26 re-list that pushed dormant items back into the 7-day freshness boost. The chart makes the cause and effect obvious, so the seller schedules a recurring re-list cadence. Because this card has no alert trigger, it is a read-and-interpret tool rather than a watchdog. Pair it with total revenue for the headline figure and average order value to see whether growth comes from more orders or pricier ones. When the trend bends, Vortex Mind traces upstream causes such as a freshness-boost expiry or a fee change, and Ask Viq answers plain-English questions like “what drove the jump in my sales after 25 May?”Sibling cards merchants should reference together

Reconciling against Mercari
Where to look in Mercari’s own dashboard: In the Mercari app, your sales history and completed-order list show each transaction with its sale price and date. Summing those sale prices over a date range should approximate the area under this chart for the same window, before any fee deductions. Why the Vortex IQ value may legitimately differ:| Reason | Direction | What to do |
|---|---|---|
| Period boundary. The chart uses a rolling 90-day window, so the start date shifts daily and may not match a fixed calendar range you pick in Mercari. | Variable | Match the period range. |
| Time zone. Orders near midnight can fall into a different day depending on the time zone used to bucket them. | Marginal | Confirm time zone match. |
| Filter scope. This card charts gross sales before fees, so it will read higher than a net-payout view. | Variable | Match filter settings. |
