Start from break-even
Take your first-year website cost. Divide by your profit per customer. That's how many sales you need. Divide that by your close rate. That's how many leads you need.
Example: $6,000 site ÷ $400 profit per customer = 15 sales. With a 25% close rate, you need 60 leads to break even in year one.
Then add a buffer
Real businesses don't close every lead at a perfectly steady rate, and traffic varies seasonally. Plan for 1.5–2x the break-even number to give yourself room.
If you need 60 leads to break even, plan for 90–120. If you can't realistically generate that many, the site needs to be cheaper, the offer needs to be higher-value, or the close rate needs to improve.
Where leads actually come from
Most small business sites get leads from a mix of search (organic and local), referrals, social media, email lists, and paid ads. The ratio depends on your industry.
Local service businesses often see 50–70% of leads from Google (organic + GBP + Maps). Coaches and consultants often see more from referrals and email. Ecommerce relies on paid social and SEO.
Track the source of every lead. You can't optimize what you don't measure.
How to project realistic lead volume
Take expected monthly visitors × visitor-to-lead conversion rate. A site getting 800 visitors/month at 3% conversion produces 24 leads/month — 288 in year one.
If you're brand new, assume 100–300 visitors/month for the first 6 months and ramp from there as SEO and content compound.
The Website ROI Calculator will run this math for you and show whether the site clears its break-even threshold.
FAQ
Where do those leads come from?
Search, referrals, social, email, and paid ads. Track sources so you know what's actually working.
What if my close rate is lower than 25%?
Then you need more leads to hit break-even — or a stronger qualification process so you only talk to good-fit prospects.
How do I increase visitor-to-lead conversion?
Clearer offer, stronger primary CTA, social proof near the CTA, fewer form fields, and a faster mobile experience usually move the needle most.
