Proxy bandwidth calculator

Estimate traffic from the number and average size of your requests. Add retry overhead, then see which current prepaid package can cover the result.

Workload inputs

Use an average from a real sample when possible.

Smallest matching package: Starter

2GB for $8.99, leaving approximately 800 MB of estimated headroom.

This is a planning estimate, not a usage guarantee. Actual metering depends on transferred traffic, retries, redirects, and application behavior. Package availability is confirmed separately at checkout.

How the bandwidth estimate works

The calculator converts each response size to megabytes, multiplies it by request count, and adds the percentage you enter for retries and overhead. It uses decimal units: 1,000KB equals 1MB and 1,000MB equals 1GB.

estimated GB = requests × size in MB × (1 + overhead ÷ 100) ÷ 1,000

The recommendation checks the exact unrounded estimate against the package data used by the store. If the estimate exceeds the largest package, the calculator says so instead of inventing another tier.

How to measure average response size

  1. Run a small sample with the same HTTP client or browser planned for production.
  2. Record transferred bytes, not only the uncompressed document or response body.
  3. Include representative successes, redirects, error pages, and downloads.
  4. Divide total transferred data by completed sample requests.
  5. Enter a retry allowance based on observed failures and normal request overhead.

Browser automation often transfers far more than a direct API request because supporting assets load through the proxy. If you block images, fonts, or media in the sample, only do so when the real workflow will use the same rules.

What the estimate does not guarantee

Actual metering can vary with headers, uploads, redirects, compression, retries, and upstream accounting. The estimate does not promise a number of successful results or uninterrupted routes. Validate it by comparing a small run with the balance shown in your dashboard.
