A freemium model lets users try basic features for free while a small share—about 3.3 %—later upgrade to paid tiers (OpenView, 2020). This calculator projects revenue and user growth by combining your current metrics with expected conversion and acquisition increases.

  1. Current monthly revenue (USD) – type figures such as 9 200 or 27 450.
  2. Current number of paying users – try 185 or 760.
  3. Conversion rate from free to paid (%) – enter 4.2 or 8.5.
  4. Projected free users – test 12 500 or 30 000.
  5. (Optional) Current monthly user acquisition – sample values 95 or 310.
  6. (Optional) Estimated % acquisition lift with freemium – input 18 or 55.
  7. Press Calculate Impact; results appear instantly.

Formulas used

Revenue projection:

$$\text{Projected Revenue}= \text{Current Revenue}+(\text{Projected Free Users} \times \text{Conversion Rate} \times \text{ARPU})$$

User-growth projection:

$$\text{Projected Monthly Users}= \text{Current Acquisition}\times\left(1+ rac{\text{Acquisition Increase}}{100}\right)$$

Example 1 — Revenue

  • Current revenue: $9 000
  • Projected free users: 12 500
  • Conversion rate: 4 % (0.04)
  • ARPU: $35

$$9 000 + (12 500 \times 0.04 \times 35)=9 000+17 500=26 500$$

Your potential monthly revenue rises to $26 500.

Example 2 — User growth

  • Current acquisition: 95 users
  • Estimated lift: 18 %

$$95 \times (1+ rac{18}{100}) = 95 \times 1.18 = 112.1 \approx 112$$

You would gain about 112 new users each month.

FAQ

What is a freemium model?

A freemium model offers core features free and charges for advanced capabilities, lowering adoption friction (OpenView, 2020).

How does the calculator find projected revenue?

It adds new paid revenue—calculated from free users, conversion rate and ARPU—to your current monthly revenue.

Why input paying users if revenue already entered?

Paying user count lets you cross-check ARPU and validate whether your revenue figure is realistic.

What’s a healthy SaaS conversion rate?

Benchmarks place healthy freemium conversion at 3–7 %; below 2 % needs pricing or onboarding tweaks (ProductLed, 2023).

How accurate are projections?

Outputs rely on your inputs; variance comes from ARPU changes, seasonality and churn, which the tool does not model.

Can I model multiple pricing tiers?

Yes—run separate scenarios with different ARPU values to approximate each tier’s contribution.

Does user acquisition lift compound over time?

The calculator shows monthly impact only; use cohort analysis for compounding effects (Reforge Growth Handbook, 2021).

What’s the quickest win after seeing results?

First, verify onboarding flows; 86 % of upgrades happen within 30 days (Appcues Benchmarks, 2022).
