About the Marketing Growth Simulator
Model spend, CAC, churn, and ARPU forward a year to see your active customers and MRR — and whether your spend actually compounds or just treads water.
It's built for directional planning: change any assumption and watch the whole projection move, the way a seasoned operator pressure-tests a plan before committing capital. Everything is computed live in your browser — nothing is sent anywhere.
How the Marketing Growth Simulator Works
The model takes 4 assumptions and returns 3 headline metrics plus a full breakdown. Here is exactly what goes in and what comes out — no black box.
The Inputs
| Assumption | Example value |
|---|---|
| Monthly spend | $20,000 |
| CAC | $40 |
| Monthly churn | 4% |
| ARPU / month | $60 |

The Operator's Read
Spend builds to about $290,468 MRR by month 12. If active customers plateau, churn is eating your spend — fix retention before adding budget.
Assumptions & Limitations
- •The model is deterministic: it projects your inputs forward with clear arithmetic, not a Monte-Carlo or probabilistic forecast. It shows one scenario at a time — run several to bracket a range.
- •Defaults are illustrative benchmarks, not your business. Replace every field with your real numbers before drawing conclusions.
- •It abstracts away taxes, financing, seasonality, and one-off events unless a field explicitly captures them. Treat the output as a directional estimate.
- •This is an educational tool, not financial, investment, tax, or legal advice. Validate real decisions with a qualified professional.
Frequently Asked Questions

Model spend, CAC, churn, and ARPU forward a year to see your active customers and MRR — and whether your spend actually compounds or just treads water. It takes 4 assumptions — Monthly spend, CAC, Monthly churn, ARPU / month — and returns Customers (mo 12), MRR (mo 12), CAC payback, along with a full projection table you can export.
How do I use the Marketing Growth Simulator?
Enter your own figures in the input fields above — Monthly spend, CAC, Monthly churn, and the rest. The model recalculates instantly and shows the resulting Customers (mo 12) and full breakdown. No sign-up needed to run it.
