The ROI of a new website vs. the hidden cost of keeping an old one

Most small businesses know their website needs work. The hard part is deciding when it is worth the investment. The best way to decide is to compare the return of a new site to the hidden cost of keeping the old one.

Start with a simple ROI model

You do not need a complex spreadsheet. Use a simple formula:

Monthly value = (qualified leads x close rate x average job value).

If your website generates 20 qualified leads a month, you close 25%, and the average job is $800, then your monthly value is $4,000. Even a modest improvement in conversion rate makes a big difference.

The hidden costs of an outdated website

Old websites rarely fail in dramatic ways. They usually fail quietly.

  • Slow load times reduce calls and form submissions.
  • Mobile layout issues push visitors away.
  • Confusing messaging makes people unsure if you are a fit.
  • Outdated visuals reduce trust even before someone reads a word.

These issues do not just lose leads. They also waste paid ad spend, referrals, and word of mouth.

What a modern site improves

A new or refreshed site typically improves three areas:

  1. Clarity: People instantly understand what you do and who you serve.
  2. Trust: Reviews, photos, and proof show you are legitimate.
  3. Conversion: Clear calls to action make it easy to call or book.

Even a 1% to 2% conversion lift can cover the cost of a rebuild in a few months.

A quick example

If your current site turns 1 out of 100 visitors into a lead, and a new site improves that to 3 out of 100, you have tripled your leads without spending more on traffic. That is a direct ROI win.

Signs it is time to rebuild

  • You hesitate to send people to your website.
  • Mobile users complain it is hard to use.
  • Your competitor sites look more modern and clear.
  • Your message feels outdated or too generic.
  • You have not updated the site in 3+ years.
