Why SaaS Users Behave Irrationally

SaaS Pricing Psychology: What Founders Miss About User Behavior

While working with SaaS founders, I’ve often seen users act in ways that make no sense—ghosting after a great demo, picking the wrong plan, or churning even after getting what they asked for.

Reading Predictably Irrational by Dan Ariely connected the dots. It turns out, users aren’t being difficult—they’re just being human. If you’ve ever felt like pricing or product decisions backfired despite good intent, these 4 behavioral biases might explain why.

1. The Zero Price Effect

Free breaks logic. Users often choose free junk over valuable paid products.

The SaaS Reality:
Freemium users get stuck in “free mode.” No matter how good the upgrade is, they don’t perceive its value.

Fix It:
Make the limits of your free tier obvious. Show what users can’t access unless they upgrade. One product I worked on added “Unlock with Pro” tags to locked features—and conversions jumped 40%.

2. Relativity Bias

People can’t decide what they want until they see something they don’t want.

The SaaS Reality:
Three similar pricing plans? Users feel overwhelmed and either choose randomly or bounce.

Fix It:
Add a “decoy” plan—an intentionally unattractive option that makes your mid-tier plan shine in comparison. This frames the decision in your favor.

3. Expectation Effects

What users expect changes how they experience your product.

The SaaS Reality:
You launch a killer feature... and nobody notices. Not because it’s bad, but because it wasn’t framed well.

Fix It:
Before the launch, set the expectation. Instead of “New dashboard,” say “Dashboard that saves 80% reporting time.” The narrative shapes how users engage.

4. Social vs Market Norms

If you mix community with sales, you kill both.

The SaaS Reality:
Trying to build a user community while sneaking in sales messages erodes trust. People feel manipulated.

Fix It:
Lead with value. Build genuine communities where the focus is helping—not selling. Let your happy users become your natural promoters.

Real Story: When “Fair Pricing” Backfired

One SaaS founder I worked with rolled out usage-based pricing, thinking it was more “fair.” Instead, churn shot up.

Why?
Users felt like they were watching a taxi meter. No price predictability = anxiety = churn.

Solution:
We added usage alerts and monthly caps. Pricing stayed the same, but users felt in control. Churn dropped.

Notion: A Masterclass in Pricing Psychology

Notion’s success isn’t just about features. They built smart pricing psychology into their product:

• Free plan? Generous enough to create daily habit loops.

• Paywall? Clear and meaningful—paid features felt like essentials, not upsells.

• Feature launches? Framed in terms of workflow transformation, not just tech specs.

The result? A $10B valuation, massive word-of-mouth, and loyal community-led growth.

Final Takeaways for SaaS Founders

• Limit your free tier and emphasize what’s missing—not what’s included.

• Use decoy pricing tiers to guide decision-making.

• Set expectations clearly so users understand the value of new features.

• Don’t blend community with selling—earn trust first.

If your users are acting “irrationally,” chances are you’re not accounting for how they think. Understanding these biases can help you create pricing, onboarding, and marketing that actually works.

Worth a read:
Predictably Irrational by Dan Ariely is not SaaS-specific, but it might be one of the most SaaS-relevant books you’ll read.
