Yes, better UX pays off: Forrester reported that visit-to-lead conversion rates can be more than 400% higher on sites with a superior user experience, and visit-to-order conversion up to 200% higher on well-designed sites [1]. Across 72 case studies, Nielsen Norman Group found an 83% average improvement in target KPIs after usability redesigns [2].
For a SaaS company, whether better UX pays off is the question behind every design budget: will it bring in more trials, demos and paying customers, or is it just polish? The UX ROI research says it moves the numbers you report on. This report shows where that happens in a SaaS funnel, which changes drive it and how to prove it on your own product.

Does better UX pay off? What the research says
We built this report on two sources anyone can open. Forrester analyst Mike Gualtieri set out how much better well-designed sites convert than poorly designed ones, and Nielsen Norman Group (NN/g), the usability research firm, collected 72 case studies of companies that redesigned for usability.
| Finding | Source | What it means for a SaaS team |
|---|---|---|
| Visit-to-lead conversion rates can be more than 400% higher on sites with a superior user experience | Forrester, 2009 [1] | More trial signups and demo requests from the traffic you already pay for |
| Up to 200% higher visit-to-order conversion on a well-designed site than on a poorly designed one | Forrester, 2009 [1] | More self-serve purchases and plan upgrades |
| Page abandonment rates up to 41% lower on well-designed sites | Forrester, 2009 [1] | Fewer visitors leaving your pricing or signup page |
| 83% average improvement in target KPIs after usability redesigns, across 72 case studies | Nielsen Norman Group, 2008 [2] | A benchmark for what a focused redesign can do |
| Spending 10% of a development budget on usability should improve conversion by 83% | Nielsen Norman Group, 2008 [2] | A rule of thumb for sizing the investment |
What did Forrester report about UX and conversion?
In a 2009 post, Forrester analyst Mike Gualtieri set out what it costs a company to leave user experience to chance, and conversion headed his list [1].
“A well-designed site can have up to a 200% higher visit-to-order conversion rate than a poorly designed site. And visit-to-lead conversion rates can be more than 400% higher on sites with a superior user experience.” [1]
Well-designed sites also have page abandonment rates up to 41% lower, the same post adds [1]. For a SaaS business, visit-to-lead is the line to watch. It's the step where a visitor becomes a trial, a demo request or a contact in your CRM, and it's where Forrester reported the widest gap.
How much does usability work improve results?
NN/g collected 72 case studies of redesigns aimed at usability and measured the change in the key performance indicator each project targeted. The average improvement was 83% [2].
NN/g left the outliers out of that average: projects that improved by a factor of 10 or more, and about 12% of projects landed there [2]. The firm also turned the data into a rule of thumb you can take into a budget meeting: “spending 10% of your development budget on usability should improve your conversion rate by 83%.” [2]
To make 83% concrete, take 2%, the conversion rate NN/g called common at the time [2], and an 83% lift turns it into about 3.7% (2 × 1.83 = 3.66). On the same traffic, that means 83% more signups, and a UX conversion rate gain like that costs nothing extra in ads.
Company-level research points the same way. Read what the McKinsey Design Index and the DMI Design Value Index found, or browse the SaaS design investment statistics.
Where does UX move revenue in a SaaS funnel?
Forrester and NN/g looked at websites broadly. In a SaaS business the same mechanics show up at four points, and each one has a metric you already track.
Signup and trial conversion
It's the homepage and landing pages that decide whether a visitor starts a trial. A headline that says who the product is for, one obvious call to action and a short signup form do more here than any clever animation. This is the visit-to-lead step from the Forrester comparison [1].
Onboarding and activation
A signup isn't a customer yet. Onboarding UX decides how fast a new user reaches the first moment of value: the first report, the first teammate invited, the first integration connected. Every extra step, vague label or empty screen with no hint of what to do next is a place where a trial can stall. Good onboarding design removes those moments one by one: a checklist that shows progress, sample data so the product never looks empty, and a clear next action on every screen until the user has seen the product work for them.
The pricing page
Buying intent peaks on the pricing page, and so does the cost of confusion. Make plans easy to compare at a glance and answer “what happens after the trial?” in plain words, and more people keep moving toward checkout. Lower abandonment on well-designed sites, as Forrester reported, is the effect to aim for [1].
Demo requests and lead forms
For sales-led SaaS, the demo form is the conversion. Cut it to the fields sales actually uses and let people book the slot right there, without a trip back to email. The shorter that path, the more interest turns into meetings in the sales calendar.
Which UX improvements drive conversion?
A full redesign isn't the only route to results. Most gains come from four kinds of work, and in our experience a senior designer spots quickly which one a funnel needs first.
| Improvement | What it looks like | Where it shows up |
|---|---|---|
| Clarity | One message per page, labels in the words your customers use, a visual hierarchy that points to the next step | Homepage, landing pages, pricing |
| Less friction | Shorter forms, fewer steps, sensible defaults, no dead ends in onboarding | Signup, onboarding, demo form |
| Trust | Consistent visual quality, customer proof close to the call to action, clear terms on plans and cancellation | Pricing page, checkout, demo form |
| Speed of iteration | Small design changes shipped often, each measured against a baseline | Every step of the funnel |
Speed is the one teams underrate: one big redesign every few years gives a single data point. A steady rhythm of smaller improvements, each checked against your numbers, compounds instead: every change teaches the team something about its users, and the next change starts from a better baseline. Each measured change also gives the team its own version of the before-and-after numbers NN/g collected across 72 projects [2].
