Arbitrage marketers and SMM specialists often choose a proxy plan "by eye" — opting for a subscription because "it's more reliable," or paying for traffic because "it sounds cheaper." In reality, the economics change depending on the volume of GB, the number of accounts, and the type of tasks. In this article, we will analyze the break-even point formula and demonstrate with real scenarios when each payment model is truly more advantageous.
Subscription vs. Pay-per-GB: What is the Fundamental Difference
A subscription is a fixed fee for a period (usually a month) with a traffic limit or unlimited access to a pool of IPs. You pay one amount regardless of whether you used 10 GB or 90 GB within the limit. This model is convenient for those who predict a stable workload: for example, managing 30 Instagram accounts every day or running ads on Facebook Ads on a constant stream.
Pay-per-traffic (pay-as-you-go) means you only pay for the actual gigabytes consumed, without being tied to the duration of the package in most cases. This model is for those with unstable loads: today you test 5 creatives, tomorrow there's a pause for a week. There is no risk of "overpaying for unused," but as volumes increase, the price per GB may be higher than in a subscription.
The key difference is not in the price per gigabyte itself, but in how you use the proxy: constantly and predictably (favoring subscription) or episodically and selectively (favoring pay-per-traffic). Next, we will analyze how this is expressed in numbers.
What Actually Consumes Traffic When Working with Proxies
Before calculating the benefits, it is important to understand where the traffic goes. Many newcomers underestimate consumption and choose an unsuitable plan.
- Warming up Instagram and TikTok accounts — viewing stories, feeds, and videos consumes more traffic than it seems: a TikTok video averages 3-8 MB per minute of viewing, and during an hour of active warming up of one account, 100-300 MB can be used.
- Facebook Ads and TikTok Ads — uploading creatives, checking moderation, updating statistics in the dashboard. One advertising account with active campaign management consumes from 500 MB to 2 GB per day if open all day in an anti-detect browser.
- Scraping Wildberries, Ozon, Avito — depends on depth: monitoring prices for 1000 products with images and specifications yields from 200 MB to 1 GB per pass, without images — significantly less.
- SMM agency with 20-50 client accounts — posting, stories, responding to comments in Dolphin Anty or AdsPower collectively yield tens of GB per month with active management.
Important: traffic consumption through proxies is almost always higher than direct connection due to additional headers and protocol overhead, especially on mobile proxies. Allow for a 10-15% buffer in your calculations.
Break-even Point Calculation Formula
The break-even point is the volume of traffic per month at which the cost of the subscription and the cost of pay-per-GB are equal. Up to this point, it is more profitable to pay for traffic; after it, a subscription is better.
Formula:
Break-even Point (GB) = Subscription Cost ÷ Price per 1 GB when paying for traffic
For example, if a subscription costs $50 per month with unlimited (or a large limit), and the price for traffic is $5 per 1 GB, the break-even point will be 10 GB. This means: if your actual traffic consumption is less than 10 GB per month — paying per GB is more profitable. If more than 10 GB — switch to a subscription.
In practice, the formula should be applied with adjustments for seasonality: arbitrage marketers may experience spikes when launching new offers, and SMM agencies may see increased loads before holidays. Calculate not based on the average month, but on the peak month if peaks are regular.
Calculation Examples for Arbitrage, SMM, and E-commerce
Case 1: Arbitrage Marketer, Farming, and Managing Facebook Ads Accounts
Manages 15 advertising accounts through Dolphin Anty, each active for 4-6 hours a day. Traffic consumption per account is about 1.5 GB per day, totaling 22.5 GB per day, or approximately 675 GB per month at full load. At this volume, a subscription is almost always more profitable — large traffic volumes make the price per GB in pay-as-you-go unjustifiably high. Here, it makes sense to consider residential proxies with a subscription, as they provide stable IPs of real users, which is critical for passing Facebook checks.
Case 2: Freelance SMM Specialist, 5 Client Accounts
Manages 5 Instagram accounts, posting 1-2 stories and posts per day, responding to comments. Total consumption is 3-5 GB per month. At such a low volume, paying for traffic is almost always more profitable than a fixed subscription, as most of the subscription limit will remain unused.
Case 3: Wildberries Seller, Competitor Monitoring
Scrapes 5000 product cards once a day with price and stock updates. Consumption is about 2-3 GB per day, or 60-90 GB per month. This is an average volume where specific plans need to be compared precisely: if the price per GB in pay-as-you-go is low, paying for traffic may remain profitable even at this volume. For stable scraping without blocks, data center proxies are often used — they are faster and cheaper for tasks that do not require masking as a mobile user.
Case 4: TikTok Ads Arbitrage Marketer, Creative Testing
Launches tests irregularly: 2 weeks of active work, 2 weeks of pause. Average consumption is 20 GB during active weeks, 0 GB during the pause. Here, paying for traffic is more profitable because the subscription continues to charge even during downtime. For unstable loads on TikTok, mobile proxies with pay-per-traffic are often chosen — this reduces the risk of blocks without overpaying for unused days.
Comparative Table by Traffic Volume
| Monthly Traffic Volume | More Profitable Model | Typical Scenario |
|---|---|---|
| Up to 10 GB | Pay-per-traffic | 1-3 Instagram accounts, rare scraping |
| 10-50 GB | Depends on the plan, precise calculation needed | 5-10 client accounts, regular but small scraping |
| 50-150 GB | Subscription is more common | Marketplace monitoring, 10-15 advertising accounts |
| Over 150 GB | Subscription is almost always | Agency with 30+ accounts, large-scale arbitrage |
Hidden Costs of Each Model
When choosing a model, it is easy to overlook non-obvious expenses that ultimately change the picture.
Hidden Costs of Subscription:
- Unused traffic limit in months with low load — essentially lost money.
- Tied to the billing cycle: if the project stops for half a month, payment is still fully deducted.
- Subscriptions are often sold in packages (for example, only 100 or 250 GB), and intermediate values may not be available — you either have to overpay or buy traffic separately.
Hidden Costs of Pay-per-Traffic:
- As volumes increase, the price per GB is usually higher than in a subscription — the scale effect does not work in your favor.
- Harder to predict the budget: consumption can spike sharply due to unoptimized automation or unnecessary requests in the scraper.
- Constant monitoring of the remaining traffic is needed to avoid stopping in the middle of an advertising campaign or scraping.
How to Choose a Model for Your Task
Focus not on abstract benefits, but on the nature of your load:
- Stable daily load (managing 10+ accounts, constant arbitrage) — a subscription is almost always more profitable, especially if the volume exceeds the break-even point from your calculation.
- Seasonal or project-based work (launches once a month, test campaigns) — pay-per-traffic reduces the risk of overpaying for downtime.
- Increasing workload — it is worth recalculating the break-even point every 1-2 months. What is profitable with 5 accounts may become suboptimal with 20.
- Multiple types of tasks simultaneously (for example, both scraping and arbitrage) — sometimes it is more profitable to combine: a subscription for a stable channel and pay-per-traffic for specific tasks.
Also consider the type of proxy: mobile proxies are usually consumed more economically in terms of successful actions (less frequently banned, fewer retries), but are more expensive per GB, while residential and data center proxies provide more traffic for the same money but require more careful configuration for a specific platform.
Checklist Before Choosing a Plan
- Measure the actual traffic consumption over the last 2-4 weeks through statistics in the anti-detect browser or the proxy provider's dashboard.
- Consider seasonality and peak loads, not just the average month.
- Calculate the break-even point using the formula for the specific plans you are comparing.
- Check if the subscription is sold in packages that precisely cover your volume without a large surplus.
- Assess how predictable your load is for the next 2-3 months.
- If tasks are of different types — consider a combination of models instead of one universal model.
Conclusion
There is no universal answer of "subscription is better" or "pay-per-traffic is more profitable" — everything depends on the break-even point calculated for the specific volume and nature of your load. With stable work involving 10+ accounts and a volume of 50-100 GB per month, a subscription almost always saves the budget. For episodic tasks and volumes up to 10-20 GB, pay-per-traffic protects against overpaying for unused limits.
Before choosing a plan, calculate your actual consumption for the last month and apply the formula from the article. If you plan to scale your work with advertising accounts or multi-accounting on social media, we recommend looking into residential proxies — they work well with both subscriptions and pay-per-traffic, allowing you to adjust the model as your load increases without losing IP quality.
