How much is poor UX costing
your startup's early growth?
For early-stage startups, every visitor counts more than at scale. A bad first impression doesn't just lose one customer — it costs you word-of-mouth, investor credibility, and the compounding growth you're trying to build. This calculator shows the real cost.

Why UX friction is expensive in Startup.
Early traffic is your most valuable — don't waste it on a broken funnel
Launch traffic, Product Hunt traffic, and early PR coverage are non-renewable. If your conversion rate is 2% when it could be 6%, you permanently lose two-thirds of those early visitors. You can't go back and re-convert them.
UX signals investor confidence
Investors evaluate execution quality through your website. Poor UX — confusing nav, unclear value prop, or weak trust signals — signals poor product thinking. Strong UX on a simple site communicates that you understand your user.
Your CAC is higher than you think without conversion optimisation
Every dollar spent on acquisition is wasted at the conversion rate you're running now. Improving conversion before scaling ads is the most capital-efficient growth move available to an early-stage startup.
Common questions
We're pre-revenue. Which numbers should I use?
Use your waitlist signup rate or free account creation rate as your conversion metric, and your target MRR per customer as the revenue figure. The calculator shows you what each percentage point of conversion improvement is worth at your projected scale.
We're getting Product Hunt / HN traffic but not converting. What's wrong?
Launch traffic has high intent but zero brand familiarity. The most common issues are: unclear value proposition (they don't understand what it does in 5 seconds), missing trust signals (who built this and why should I trust them), and friction in the signup flow. Our AI Website Roast will identify the specific issues.
How do I know if UX is the problem vs. product-market fit?
If visitors engage — scroll, click, spend time — but don't convert, it's UX. If bounce rate is very high and session duration is low, it could be positioning or PMF. The calculator combined with an audit helps you isolate which lever to pull.
