TLDR: Our calculator shows you how a strategic website redesign can increase your conversion rate by up to 47%, how many additional clients you’ll gain monthly, how much extra revenue that represents, and exactly how long it will take to recover your investment. Based on a study of 396 businesses that boosted their conversion rates from 2.3% to 3.4% through website improvements.


Every business owner faces the same question when considering a website redesign: Will the investment actually pay off?

That’s exactly why I built this calculator. After years in the design industry, I’ve seen firsthand how strategic website improvements can transform conversion rates and revenue—when done properly.

The Real Impact of Website Redesign

Whether you’re running an independent shop or scaling a tech startup, your website’s effectiveness directly impacts your bottom line.

Research backs this up: a comprehensive study of 396 businesses across various industries found an average 47% increase in lead conversion rates after website redesigns. Their conversion rates jumped from an average of 2.3% to 3.4% after implementing improvements like clear calls-to-action, optimised lead capture forms, and strategic landing pages.

The key word here is strategic. Simply refreshing your visual design without addressing underlying conversion issues won’t deliver meaningful results.

What Our Calculator Shows You

Our ROI calculator focuses on three metrics that directly impact your business:

1. Conversion Improvement

See how your lead-to-client conversion rate would improve with industry-standard enhancements. For example, improving from 2.5% to 3.7% might seem small, but the impact on your business is significant.

2. Revenue Impact

Understand exactly how many additional clients you’ll gain monthly and what that means for your revenue, based on your specific client value range.

3. Investment Recovery Timeline

Perhaps most importantly, see precisely how long it will take to recoup your website redesign investment. Many businesses are surprised to discover they’ll break even within just a few months.

The Elements That Drive Conversion

The most effective website redesigns focus on specific elements that directly influence visitor behaviour:

  • Clear, compelling calls-to-action that guide users toward conversion
  • Streamlined lead capture forms that remove unnecessary friction
  • Strategic landing pages designed for specific audience segments
  • Improved site speed and mobile responsiveness
  • Trust signals and social proof positioned at decision points

These improvements address the common issues that cause potential clients to abandon websites before converting.

Beyond Direct Conversions

While our calculator focuses on quantifiable metrics, effective website redesigns deliver additional benefits:

  • Strengthened brand perception and credibility
  • Reduced bounce rates and increased engagement
  • Improved search engine visibility
  • Better user experiences across all devices
  • More qualified leads through strategic content positioning

This was reported by a survey of 396 businesses across various industries that underwent a website redesign in the past two years. The study found that the lead conversion rate increased from an average of 2.3% to 3.4% after the redesign, primarily due to improvements such as clear calls to action (CTAs), lead capture forms, and optimised landing pages.(Source: New Perspective Studio)
