The formula behind it
Current value is your sessions × conversion rate × average value. We assume the uplift grows in a straight line, from nothing in month 1 to your full scenario by month 12. The extra value each month is the extra sessions that month × conversion rate × average value. Break-even is the first month where the extra value added up so far covers the cost paid so far. Organic sessions only; ad spend and one-off costs aren’t included.
Real SEO doesn’t move in a straight line. Some months move a lot, some don’t move at all, and a search engine update can undo either. Use this to check whether the numbers could make sense for you, not to predict them.
