Comparing cost per unit is the most common mistake when choosing between self-registration and buying a ready batch. Registering looks almost free until you add up every cost line and, crucially, account for attrition. Let us break the cost structure down honestly: without specific figures, which differ for everyone, but with every line people usually forget.
Why cost per unit is misleading
When you register yourself, you compare the cost of one successful registration against the price of a finished account. But a successful registration is not the same thing as a working account. Between them sit aging, the first login and a validity check, and at every stage part of the batch drops out. What you should count is the cost of an account that made it into production, not the cost of an attempt.
The second trap is time. Your own time in a self-registration scheme is usually not priced at all, though it is the most expensive line: registering, warming and filtering take days during which you are not doing the job you needed the accounts for.
What self-registration actually costs
SMS reception
A separate line, and it is paid per attempt, not per success. Some numbers fail, some succeed and then turn out useless for recovery. Geo affects both price and availability.
Proxies
You cannot register a stack from one address — that links it at the start. You need a pool of mobile or residential addresses, paid for the whole registration and aging period, not just at creation.
Devices or antidetect
Every registration must appear to come from a separate environment. That is either a device fleet or an antidetect setup with profiles. Plus the time to configure each profile.
Aging
A fresh account is not ready for load. It needs weeks of quiet during which the proxy keeps being paid for while the account produces nothing. The difference between fresh and aged is covered in our piece on autoreg versus real device.
Attrition, the line everyone forgets
Attrition happens twice, and it shapes real unit cost more than any other line.
- At registration — some attempts never produce an account.
- During aging — some created accounts go to block or freeze on their own.
- At first login — some survivors fail verification in your environment.
The practical conclusion: to end up with the number of working accounts you need, you must register noticeably more, and you pay every cost line for the whole batch rather than for the surviving part. When buying, registration and aging attrition has already been absorbed by someone else, and an invalid at acceptance is covered by replacement — which is the core saving. How to size a purchase is covered in our article on buying in bulk.
When self-registration is still justified
It makes sense when you already own the infrastructure — a proxy pool, antidetect, an established process — and you need a continuous flow of accounts rather than a one-off batch. Then fixed costs spread across volume and the scheme comes out cheaper. If you need accounts for a specific task right now, buying almost always wins: fresh autoreg for volume, bulk batches for flow, budget accounts for tests.
Mini FAQ
Is self-registration always cheaper per unit?
Only if you count successful registrations and ignore attrition, aging and your own time. Include them and the picture usually flips.
How much attrition should I plan for?
No exact share can be quoted — it depends on geo, scheme and environment. The rule is simple: count accounts that reached production, not accounts created.
What is cheaper for a ten-account test?
Buying. At small volume the fixed costs of self-registration do not spread and make it plainly more expensive.
Conclusion
The right question is not what registration costs but what an account that reached the task costs. In that frame self-registration is justified with ready infrastructure and continuous flow, while for a one-off job buying is cheaper and faster. And count attrition — that, not the price of a number, sets your real unit cost.
