Lead Spend Calculator
What this shows
What happens over 24 months if you keep buying all your leads, compared with moving part of that budget into your own audience. Same total spend either way. The difference is what you own at the end.
How to read this
The "buying only" line is flat because bought leads only last as long as the payments. The "building" line dips first, because part of the budget stops buying leads before your own sources start producing. That dip is the real cost of building, and it's why we recommend shifting gradually.
After that, the lines cross where your own traffic starts carrying the load. The number that matters most is the last one: how many leads a month you'd have coming in that don't depend on a vendor. That's the part you keep.
For the thinking behind this, read buy, rent or build and alternatives to buying leads.
