Why You Need It

Setting sensible lead targets and marketing budgets is one of the biggest challenges for SaaS teams.
How many leads do you really need to hit your revenue goals? What’s a realistic conversion rate or CPC baseline?

The SaaS Leads Modeller helps you answer these questions instantly and credibly.

How It Works

Input your key metrics such as conversion rates, CPC, revenue targets, and deal values.
The model calculates:

  • How many visits you need to reach your lead target

  • How many leads you must generate to hit your ARR goal

  • The marketing budget required to achieve it

You’ll see your entire SaaS funnel visualised from top-of-funnel visits to closed-won deals so you can plan with data, not guesswork.

What to Enter

Use data from your CRM or analytics tools such as Salesforce, HubSpot, Matomo, or Google Analytics.
If you don’t have full visibility yet, start with industry averages. The modeller will still help you find your performance gaps.
