TL;DR: Proxy bandwidth is driven by payload size, protocol overhead, and repeat requests. Calculate from your measured average response size and add a buffer before selecting a plan.
- Payload. Larger HTML pages, JSON responses, images, and media consume more bandwidth. Request only the fields and assets your workflow needs.
- Headers. Request and response headers add data to every transfer. Avoid unnecessary headers and use compressed responses where supported.
- Retries. Timeouts, redirects, and failed requests can send traffic more than once. Use retry limits and a realistic safety margin.
How to use this online bandwidth calculator in 3 steps
- Choose an average request size. Start with a use-case preset or enter the average response size from your logs.
- Enter your request volume. Convert an existing GB allowance to requests, or enter total requests or a daily campaign plan to estimate required GB.
- Add a buffer and choose a plan. Set a safety margin for headers, retries, and response variance, then use the recommended bandwidth tier as your starting point.
How requests and GB are calculated with this data bandwidth calculator
For GB to requests: floor(bandwidth bytes ÷ average request bytes) × (1 − safety margin)
For requests to GB: ceil(requests × average request bytes × (1 + safety margin))
Decimal uses 1 GB = 1,000,000,000 bytes. Binary uses 1 GiB = 1,073,741,824 bytes. Check your provider's billing terms before comparing estimates.
Requests per 1 GB
No safety margin. Decimal basis.

Ways to reduce proxy bandwidth
Request compressed responses with gzip or Brotli when supported. Block images, CSS, and JavaScript when your workflow only needs text or structured data. Use conditional requests such as If-Modified-Since or ETag to avoid downloading unchanged content.
Proxy Bandwidth Calculator FAQ
It depends on the average data transferred per request. At 100 KB per request on the decimal basis, 1 GB is about 10,000 requests before a safety margin. At 500 KB per request, the same 1 GB is about 2,000 requests.
Use the average response size from your logs when available. Otherwise, start with a matching use-case preset and adjust it for images, JavaScript, compression, API payloads, and the content you actually download.
Usually, yes. Any request and response data transferred before a failure can count toward usage, and retries can send similar traffic again. Add a safety margin to account for failures and retries.
They can be. Headers add data to every transfer and can matter when response bodies are small. The calculator uses your average request-size input and the safety margin to account for that overhead.
A margin makes the estimate more conservative. It helps cover response-size variation, headers, redirects, retries, and failed requests so you are less likely to run out of traffic during a campaign.
Decimal GB uses 1,000,000,000 bytes. Binary GiB uses 1,073,741,824 bytes. Most proxy plans use decimal GB, but you should follow the billing basis documented by your provider.
No. It is a planning estimate. Actual billing depends on your provider's metering rules, transferred data, compression, request headers, retries, and the behavior of target websites.
Use the recommended tier as a starting point because it rounds your estimated requirement up to an available bandwidth package. Review the included buffer and choose a larger plan if your workload is likely to grow or vary.
