About the Marketing Payback Simulator
Model monthly spend acquiring customers who pay back over time, and find the month cumulative margin overtakes cumulative spend.
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 Payback Simulator Works

The Inputs
| Assumption | Example value |
|---|---|
| Monthly spend | $20,000 |
| CAC | $40 |
| Contribution / customer / mo | $30 |
| Monthly churn | 4% |

The Operator's Read
Steady spend runs a loss until the customer base is large enough to out-earn it. That trough is the cash you must fund — under-capitalized growth dies in this valley even when the model works.
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.
