Form is the percentage of users who begin entering information into a form, usually checkout, then leave before submitting it. It isolates dropoff during the form itself, which is narrower than overall cart abandonment.
How do you calculate form abandonment rate?
Form Abandonment Rate = ((Form Starts - Form Completions) / Form Starts) x 100
A form start usually counts once the user focuses on or types into at least one field.
Why do users abandon forms?
- Too many fields, so the form feels like work.
- Confusing labels or validation rules that are hard to satisfy.
- Errors, slow loading, or data lost after a mistake.
- Requests for information that feels unnecessary or sensitive.
- A final total higher than expected once details are entered.
Forced account creation is a documented driver. Around 26% of shoppers have abandoned a checkout because the site required an account, and roughly 18% left because the process was too long or complicated, according to Baymard Institute research.
How do you reduce form abandonment?
- Ask only for the fields you truly need and drop optional ones.
- Support browser autofill and .
- Offer guest checkout instead of forcing account creation.
- Show progress on multi-step forms and preserve entered data.
- Use clear labels and so errors surface early.
The field-level details matter here. Our checkout form design guide covers labels, input types, and validation, and our cart and checkout error message templates show how to keep validation errors from pushing people out.
How should you track form abandonment?
Track abandonment at the field level to see exactly where people stop, watch for fields where users hesitate, and segment by device, since mobile forms tend to lose more people. For the structural fixes across the wider flow, our checkout optimization guide covers what to change.
