Find a problem people already care about
Choose one audience, one recurring obstacle and one outcome they actively want. Generated ideas are starting points; confirm the language through current searches, comments and real conversations.
Estimate how traffic may turn into subscribers, buyers and monthly contribution. Then use the workflow below to strengthen the weakest assumption—without pretending a forecast is guaranteed revenue.
Start with a cautious scenario. Every result is an estimate based only on the assumptions you enter.
Contribution estimate = gross sales − estimated refunds − payment fees − entered monthly costs. It excludes income tax, VAT/GST/sales tax, chargebacks, labor and other business expenses.

Traffic alone is not a business. Start with a recurring problem, publish evidence that you can help, earn attention, then offer a clear next step.
Choose one audience, one recurring obstacle and one outcome they actively want. Generated ideas are starting points; confirm the language through current searches, comments and real conversations.
Teach one useful task, demonstrate the process and separate verified facts from opinion. One strong source can become multiple platform-specific pieces.
A lead magnet should solve the next small problem—not hide generic advice behind an email form. Test whether real people want it before automating delivery.
Package a repeatable result as a template, guide, toolkit, workshop or productized service. Price from costs and assumptions, then compare that estimate with real customer value and alternatives.
State who the offer helps, the problem it addresses, how it works and what evidence supports it. Avoid guaranteed outcomes, fabricated scarcity and testimonials without permission.
Can you point to repeated searches, questions, purchases or conversations around the problem?
Can you demonstrate the process or result without exaggerating what caused it?
After fees, refunds, taxes, support and acquisition costs, is the offer still viable?
Results depend on demand, positioning, execution, distribution, pricing and compliance. Validate assumptions with small tests before committing substantial time or money. Check tax and consumer-law duties for every market where you sell.
The built-in cautious example uses 5,000 monthly visitors, 3% opt-in, 2% subscriber-to-buyer conversion, a $19 offer, 5% payment fees plus $0.50 per sale, a 5% refund assumption and $50 monthly costs. Here is the arithmetic the calculator applies:
| Stage | Calculation | Estimate |
|---|---|---|
| Subscribers | 5,000 × 3% | 150 |
| Purchases | 150 × 2% | 3 |
| Gross sales | 3 × $19 | $57.00 |
| Refund reserve | $57 × 5% | $2.85 |
| Payment fees | 3 × ($19 × 5% + $0.50) | $4.35 |
| Contribution estimate | $57 − $2.85 − $4.35 − $50 | −$0.20 |
Under these assumptions, four purchases would be needed to cover the entered $50 monthly cost. This is a scenario calculation, not a forecast: it excludes taxes, chargebacks, labor and other expenses, and the conversion rates must be replaced with observed results before increasing spend.
Reproducible calculation · October 24, 2026
150 subscribers × 2% = 3 expected purchases. Gross $57 − refunds $2.85 − processing fees $4.35 − overhead $50 = −$0.20 contribution. Each sale contributes $16.60 before overhead, so 4 whole sales cover the entered $50. These are scenario assumptions, not observed conversion rates.
