How to use this calculator

  • Enter your target monthly recurring revenue.
  • Add average subscription price and funnel conversion rates.
  • Include churn so the required customer target reflects replacement demand.

What the result means

The result translates a revenue target into a practical acquisition requirement. If required leads are too high, improve price, conversion, or churn before scaling spend.

Customers Needed = Target MRR / Price. Trials Needed = Customers / Trial Conversion. Leads Needed = Trials / Lead-to-Trial Rate.

High churn raises the acquisition burden because new customers must replace lost accounts before growth is visible.

Example calculation

A $50,000 MRR goal with a $100 plan requires about 500 active customers before churn adjustment. At 20% trial conversion and 10% lead-to-trial rate, the required lead volume is much higher.

Tips for better results

  • Improve onboarding before buying more traffic.
  • Segment customers by plan price and conversion quality.
  • Use annual contracts to reduce churn pressure.

FAQ

How many customers do I need for $100k ARR?

Divide $100k ARR by annual revenue per customer. If your plan is monthly, multiply price by 12 first.

How many SaaS leads become paying customers?

The number depends on lead-to-trial and trial-to-paid conversion. This calculator estimates required leads from both funnel stages.

What conversion rate should SaaS companies target?

Targets vary by market and sales motion, but trial-to-paid conversion often becomes a key lever for efficient SaaS growth.

How do I forecast SaaS customer growth?

Start with current customers, add new paid customers from the funnel, and subtract churned customers each month.

How many subscriptions do I need to hit my revenue goal?

Divide the target revenue by average subscription price, then adjust for churn and conversion rates.
