What this estimate does and does not tell you

This calculation uses gross profit rather than revenue. That matters because a $5,000 job is not worth $5,000 to your business after the direct cost of delivering it.

The projection also builds results over time instead of pretending the campaign produces its full return in month one. Change the ramp period to test a slower or faster scenario.

It is still a forecast, not a guarantee. Ranking difficulty, search demand, your website, your sales process and the quality of the SEO work all affect the result. The useful number is the break-even target: how many genuinely additional customers the investment must create to make financial sense.
