Struggling to decide whether your SaaS subscription price is too high or too low? In the next few minutes you’ll get a ready‑to‑use pricing formula, the exact numbers you need to plug in, and a quick test plan that turns guess‑work into data‑driven growth. No more spreadsheet paralysis—just a clear, repeatable process you can apply today.

Why Guess‑Work Pricing Fails

Most founders set prices based on gut feeling or what a competitor seems to charge. The result? Low sign‑ups, high churn, and wasted marketing spend. The core problem is missing three critical inputs:

• Customer acquisition cost (CAC) – what you spend to land a paying user.
• Lifetime value (LTV) – the total revenue a customer generates before they leave.
• Churn rate – the monthly percentage of users who cancel.

Without these, any price is a shot in the dark.

Step‑by‑Step Pricing Formula

1. Collect the data

   • CAC: total marketing & sales spend ÷ number of new paying users.
   • LTV: average monthly revenue per user × (1 ÷ churn rate).
   • Desired margin: the profit percentage you aim to retain after covering costs.

2. Plug into the formula

   [
   \text{Price} = \frac{\text{LTV} \times \text{Desired Margin}}{\text{Expected Months}}
   ]

   Expected Months = 1 ÷ churn rate.

   Example:

   • CAC = $30
   • Monthly churn = 5 % → Expected Months = 20
   • LTV = $50 × 20 = $1,000
   • Desired margin = 70 %

   [
   \text{Price} = \frac{1{,}000 \times 0.70}{20} = $35
   ]

   In this scenario a $35/month plan aligns with the math, whereas a $49 plan would under‑price the value.

3. Adjust for market fit

   • Benchmark against similar SaaS tools.
   • Factor in unique features or service levels.

4. Validate with a test

   • Offer two price points (e.g., $35 vs $45) to a small segment.
   • Track conversion, CAC, and churn for 2‑4 weeks.
   • Choose the tier that maximizes profitability and retention.

Testing & Optimizing Your Price

• A/B test: Randomly assign visitors to different pricing pages.
• Cohort analysis: Compare churn between the two cohorts over time.
• Feedback loop: Survey early adopters on perceived value vs price.

Iterate until the data shows a stable subscription pricing strategy with churn under your target threshold.

Quick Tools & Takeaways

• Pricing model calculator – just plug CAC, churn, and desired margin to get an instant range.
• Worksheet download – a ready‑made spreadsheet that auto‑calculates the formula (link in sidebar).
• Key takeaways
  1. Gather CAC, LTV, and churn before setting any price.
  2. Use the SaaS subscription pricing formula to establish a data‑backed baseline.
  3. Test, measure, and refine—pricing is a loop, not a one‑time decision.
