The research behind signup drop-off

Every number on signupdrop.com comes from one of the sources below. Here is each one, the work they have published, and the specific benchmarks we cite from them. If a claim on this site does not trace back to one of these sources, it should not be here.

Baymard Institute

UX research firm founded by Christian Holst. Publishes large-sample usability benchmarks for checkout and signup flows. Their database is the gold standard for e-commerce and SaaS form abandonment data.

~10ppAverage conversion drop per additional form field (aggregated across checkout and signup studies)

69.9%Average checkout abandonment rate (2024 benchmark study, n=4,000+ sites)

~12-15%SSN / national ID field causes catastrophic drop in non-regulated contexts

The deeper benchmark database is paywalled (approximately $200/month). Public articles on baymard.com give partial data. For practitioners who run form audits regularly, the subscription is worth it.

Nielsen Norman Group

Usability research firm founded by Jakob Nielsen and Don Norman in 1998. Publishes peer-reviewed research on web usability, form design, error states, and digital trust.

3-7ppConfirm password field drop-off (the field is zero-value; replace with visibility toggle)

20-50ppSSN / national ID fields in non-regulated contexts (catastrophic trust break)

HighDense Terms and Privacy checkbox with no summary materially increases abandonment

Nielsen Norman research is published at nngroup.com. Articles are detailed and practitioner-readable. Reports are sold separately; articles are free.

Luke Wroblewski

Author of Web Form Design: Filling in the Blanks (Rosenfeld Media, 2008). Formerly Principal Designer at Google, VP of Design at Yahoo. Published extensively on form UX at lukew.com. The book is the canonical reference for form design practitioners.

HighInline validation lifts form completion vs validate-on-submit (original research in the book)

HighVisibility toggle on password fields reduces errors and increases completion

HighOne thing per page pattern reduces cognitive load for long signup flows

Web Form Design by Wroblewski is the practitioner standard. Published 2008, still cited as authoritative in 2026 because the fundamentals have not changed.

Segment (Twilio Segment)

Customer data platform vendor. Publishes annual signup and onboarding benchmarks aggregated from customer data. One of the few vendors publishing honest auth-method conversion deltas.

60-80%Median SaaS signup drop-off across auth methods (2024 benchmark)

+15-25ppAverage conversion lift from Google OAuth over email+password (2023 benchmark)

5-15ppMobile conversion is lower than desktop across most SaaS categories

Segment benchmarks are published via their blog and research content hub. Numbers are aggregated across real customer data, making them more reliable than vendor surveys.

Statsig

Experimentation and feature-flag platform. Publishes public benchmark data on signup and onboarding A/B tests aggregated across their customer base. Increasingly cited in growth-PM circles for honest experiment data.

VariesSignup variant lift data across authentication method tests (customer aggregated)

~35-55%Email+password baseline signup completion rate across B2C SaaS

High varianceMagic link vs password lift is context-dependent (product category matters)

Statsig publishes benchmark reports at statsig.com/blog. The data is genuinely drawn from real experiments, not surveys.

Auth0 / Okta

Authentication vendor. Publishes customer case data on magic-link, password, and social-login signup conversion deltas. Self-serving in the direction of promoting passwordless, but the data points are real.

+15-30ppMagic link lift on signup completion vs email+password (customer case data)

8-20ppHard email-verify gate conversion cost (case data from PLG customers)

~70%Users who verify their email do so within 24 hours

Auth0 research is published at auth0.com/blog and in their developer documentation. Honest caveat: they benefit from you using passwordless, which creates some selection bias in case-study selection.

HubSpot

Marketing-tech vendor. Publishes large-sample form-conversion benchmarks drawn from their vast customer base. One of the most-cited sources for average form conversion rates and the number-of-fields curve.

2.35%Average form conversion rate across landing pages (most recent benchmark, wildly variable by industry)

1-3%First name field drop-off (low friction, low value)

1-3%Last name field drop-off (often paired with first)

5-15%Required marketing opt-in field drop-off (never make it required)

HubSpot form benchmarks are published in their State of Marketing reports and on the HubSpot blog. Biased toward their use case but sample sizes are substantial.

Formisimo / Zuko

Form analytics vendor (rebranded from Formisimo to Zuko). Publishes per-field abandonment data from session-recording analysis of real form interactions. The closest published data to Baymard's field-level research that is publicly accessible.

3-12ppRequired phone number field drop-off (high perceived privacy risk)

2-5ppCompany name field drop-off (B2B-justifiable; can be enriched from email domain)

2-4ppRole / job title field drop-off (B2B-justifiable; use a dropdown)

Formisimo/Zuko research is available on their blog and in published benchmark reports. Their data is particularly valuable for per-field comparison since it comes from live form-session analysis.

NIST SP 800-63B

US National Institute of Standards and Technology, Digital Identity Guidelines. The federal government's own specification for password policy in digital systems. NIST 800-63B is the most-ignored research in consumer web signup UX.

8 charsMinimum password length NIST recommends (should-allow up to 64)

ProhibitedForced password composition rules (uppercase + lowercase + number + symbol requirements are explicitly deprecated)

ProhibitedForced password rotation on a schedule (only rotate on evidence of compromise)

NIST SP 800-63B is available free at nist.gov. The relevant sections are 5.1.1 and 5.1.1.2. Written for government systems but explicitly referenced by security professionals for all digital identity contexts.

Userpilot

Product analytics and onboarding vendor. Publishes research on email verification, onboarding drop-off, and PLG patterns. Less rigorous than Baymard but useful for real-world case data on modern SaaS patterns.

8-20ppDrop-off from hard email-verify gate before first use (case study data)

HighVerify-later and soft-verify patterns materially reduce this cost

Userpilot research is published on their blog and in their Product Adoption Benchmark reports. Self-serving toward their platform but case data is from real customers.
