Each field below is an unnecessary friction point draining revenue from your checkout.
These fields are frequently unnecessary and add friction without value.
Phone Number (secondary)
Most stores only need one contact method. Remove the landline or secondary phone field.
Company Name
Unless you sell B2B, this field adds friction for 95%+ of buyers.
Address Line 2
Make this optional and collapsed by default. Most addresses fit in one line.
Fax Number
It is 2026. Remove this.
Confirm Email
Typo-checking can be done with inline validation instead of a duplicate field.
"How did you hear about us?"
Move this to the post-purchase thank-you page where it won't cost you conversions.
Separate Billing Address
Default to "same as shipping" with an opt-in toggle. Most orders ship to the billing address.
Research from the Baymard Institute and other UX studies consistently shows that each unnecessary form field reduces checkout completion rates by approximately 3-5%. The exact impact depends on the field type, device, and audience — but the effect compounds with every additional field.
The average optimized checkout has 7-8 form fields. Top-performing Shopify stores often get down to 6-7 by using smart defaults, auto-detection (like postal code lookup for city/state), and removing non-essential fields like company name or secondary phone.
This calculator uses a single drop-off rate for simplicity. In practice, the cost per extra field is higher on mobile — where typing is harder and screens are smaller. If mobile makes up a large share of your traffic, consider using the higher end of the 3-5% range.
Start with fields that add zero value to order fulfillment: secondary phone, company name, fax, "how did you hear about us," and confirm email. Then look at fields you can auto-fill or collapse — like making Address Line 2 optional and defaulting billing to shipping address.
Yes — if the fields you remove are genuinely unnecessary. A/B tests by major ecommerce brands consistently show that shorter checkout forms convert better. The key is removing fields that do not contribute to fulfilling the order, not removing required information like the shipping address.
