Real growth simulations for subscription and membership businesses
Honest calculators that show what actually happens when churn, pricing, and acquisition collide. No fantasy curves. No fluff.
Why use RealGrowthMetrics?
Realistic projections, not fantasy curves
Most growth calculators ignore churn, assume perfect retention, and show exponential curves that never materialize. Our simulators model real-world constraints: monthly churn, acquisition costs, and pricing sensitivity. See what actually happens to your business over time.
Make better decisions faster
Compare scenarios side-by-side. What happens if you reduce churn by 1%? How does a price increase affect revenue when churn increases? Model multiple outcomes instantly to understand trade-offs before committing to a strategy.
Built for operators who need the truth
Whether you're planning budgets, setting targets, or evaluating strategies, you need projections grounded in reality. These tools help you communicate realistic expectations to stakeholders and make informed decisions based on actual business dynamics.
Free, no signup required
No accounts, no email collection, no hidden costs. Just honest calculators you can use immediately. All calculations run in your browser-your data never leaves your device.
