From the margin calculator — profit divided by price, as a percentage.
Subscriptions, bookkeeping, any salary.

Frequently asked questions
- What counts as fixed costs?
- Things you pay regardless of sales: apps/subscriptions, bookkeeping, any salary to yourself. Ad budget is variable but entered separately since it's often the biggest line item.
- Runway shows 120 months — what does that mean?
- 120 (10 years) is the calculator's cap. Your cash flow is already positive under today's assumptions, so the capital isn't shrinking — it's not a real 10-year-ahead forecast.
