What CAPTCHA Solving Actually Costs

The sticker price on a CAPTCHA solving service is almost never what you actually pay. Two services can both say "$1 per thousand" and cost you wildly different amounts by the end of the month, because the price per solve is only one line in the bill. The rest hides in failed attempts, proxies, and the plan you didn't need.

Here's the honest breakdown of where the money goes, and a way to estimate your real cost before you commit.

The pricing models you'll see

Per-solve (pay as you go). You're quoted a rate per thousand solves. At Peak that's $0.90 per 1,000, so $0.001 a solve, a tenth of a cent. You add funds and draw them down as you solve. No monthly floor, no expiry games.

Subscription / threads. Some services sell monthly plans priced by concurrent "threads" rather than solves. This can look cheap per solve at high volume, but you pay the full monthly rate whether you send one request or a million, and unused capacity is gone.

Credits. A middle ground where you buy a bucket of credits, sometimes with an expiry date. Watch the expiry; credits you don't burn in time are just a price increase.

The cost nobody prints: failed solves

This is the big one. Ask any service a single question: do I pay for failed solves? If a service bills every attempt, your effective price is the quoted rate divided by the success rate. A "$1 per thousand" service that only lands 80% of the time actually costs you $1.25 per thousand successful tokens, and you feel it most on hard targets where failures cluster.

Peak bills only on a successful solve. A miss costs nothing, so the rate you're quoted is the rate you pay. When you compare services, normalize everyone to cost-per-successful-solve, not cost-per-attempt, or you're comparing fiction.

The other cost: proxies

Most Cloudflare work needs a proxy, and on the challenges that bind to an IP (the 5-second challenge and its cf_clearance cookie) it needs a sticky residential or mobile one. Proxy bandwidth is a separate bill from your solving spend, and for scraping-heavy jobs it can dwarf the solve cost. Budget for it explicitly instead of being surprised. If you're weighing proxy types, the cf_clearance cookie explains why the IP has to stay constant.

A worked example

Say you need 50,000 successful Turnstile tokens this month. On a pay-per-solve service at $1 per 1,000 that bills only on success:

50,000 solves x $0.001 = $50.00
failed solves: billed nothing
total solving spend: $50.00 (+ your proxy bandwidth)

Now the same 50,000 on a service that charges per attempt at the same headline rate, landing 85%:

to get 50,000 successes at 85% success,
you attempt ~58,800 times
58,800 x $0.001 = $58.80 for the same 50,000 tokens

Same sticker price, ~18% more out of pocket, and that gap widens on harder targets. The number that matters is always cost per successful solve.

How to estimate your bill honestly

• Volume. How many successful solves per day, realistically, not peak.
• Billing basis. Per success or per attempt? Divide the rate by the real success rate if it's per attempt.
• Proxy spend. Estimate bandwidth separately; it's often the larger line.
• Floor and expiry. Any monthly minimum or credit expiry is part of the price.

Put those four numbers together and you have a real budget instead of a headline. For the full vendor-comparison checklist, see how to choose a CAPTCHA solving service.

FAQ

How much does CAPTCHA solving cost?

Pay-per-solve services commonly run around $1 per 1,000 solves, or $0.001 each. Your real cost depends on whether failed solves are billed and on your proxy bandwidth, which is a separate charge.

Do I pay for failed solves?

With some services, yes; with Peak, no. It matters a lot: if a service bills every attempt, your true cost is the quoted rate divided by its success rate. Always compare cost per successful solve.

Is pay-per-solve or a subscription cheaper?

Pay-per-solve fits variable or growing volume because you only pay for what lands. Subscriptions can win at steady high volume but charge the full rate even when idle. See pricing to compare against your numbers.
