At a glance
Form Abandonment Rate % is a frustration-signal metric tracked from FullStory data. It measures the share of visitors who started interacting with a form, a checkout step, a newsletter signup, an account creation, and then left without submitting it. Because FullStory captures the field-level interaction, this is not a guess: it knows the visitor focused a field and never completed. A high rate flags forms that are too long, confusing, or throwing validation errors that the visitor cannot get past.
| What it counts | The percentage of form-interaction sessions in the period that ended without a successful submission, as captured by FullStory. |
| Sample type | Backend API data from FullStory, refreshed on the standard data refresh. |
| Why it matters | Forms sit on the most valuable paths: checkout, registration, lead capture. A high abandonment rate is lost revenue or lost contacts, and the replays show exactly which field stalled people. |
| Reading the value | Compare the current period to the prior period. Drill into the replays of abandoned sessions to find the field where visitors give up. |
| Currency | percent |
| Time window | 30D vsP |
| Alert trigger | >40% |

Calculation
Calculated automatically from your FullStory data. FullStory detects form interaction and submission events; Vortex IQ divides started-but-not-submitted form sessions by total started-form sessions for the period. See the At a glance summary above for what the metric tracks and the worked example below for a typical reading.Worked example
A representative reading of Form Abandonment Rate % for a typical merchant on FullStory. Suppose the checkout form shows a 47% abandonment rate, over the 40% guardrail. Replays of abandoned sessions cluster on the phone-number field, which rejects spaces without a clear message. Visitors retype, fail again, and leave. Relaxing the validation drops abandonment back toward the high thirties. Without this card the merchant would only see a soft checkout conversion rate with no field-level cause. For deeper investigation, use Vortex Mind to trace the abandonment to specific fields; for natural-language exploration, ask Ask Viq which forms abandon most.Sibling cards merchants should reference together
| Card | Why merchants reach for it |
|---|---|
fs_checkout_path_frustration | Frustration events specifically on cart and checkout pages. |
fs_error_click_rate | Validation failures often show up as error clicks. |
fs_rage_click_rate | Repeated clicks on a submit button that will not progress. |
fs_frustration_score | The composite frustration number this feeds into. |
ful_cart_abandonment_rate | The downstream commerce abandonment this often precedes. |
Reconciling against the vendor’s own dashboard
Where to look in FullStory’s own dashboard: FullStory surfaces form interaction through its funnel and conversion tooling, where you can define a form-start and form-submit step. Confirm the form definition and period match the Vortex IQ profile to reconcile cleanly. Why the Vortex IQ value may legitimately differ:| Reason | Direction | What to do |
|---|---|---|
| Period boundary. Vortex IQ uses 30-day rolling by default; FullStory dashboards may use calendar periods. | Variable | Match the period range. |
| Form definition. Which fields count as a “start” can be drawn differently in a hand-built FullStory funnel. | Variable | Align the start and submit definitions. |
| Segment scope. A FullStory segment may exclude traffic the Vortex IQ profile includes. | Variable | Match segment and filter settings. |
