How the calculator works
Each month the model:
- Removes the share of existing customers who cancel (your churn rate).
- Adds your new customers.
- Multiplies active customers by your plan price to get subscription revenue.
- Adds profit from NFC card sales.
- Subtracts your monthly running costs.
Your one-time setup cost is taken off at the start, so the chart shows exactly when the business pays for itself.
The three numbers that matter most
| Lever | Why it matters | How to improve it |
|---|---|---|
| Churn | Caps how big your customer base can get | Onboard customers properly, offer yearly plans, add features they rely on |
| Price | Every extra dollar or rupee multiplies across every customer | Tier your plans; charge more for custom domains, analytics and NFC |
| New customers | Grows the base | Partner with print shops, local agencies and networking groups |
A small change in churn often beats a big push in marketing. Try it: move churn from 8% to 4% in the calculator and watch where your customer count levels off.
