Proxy Bandwidth Calculator
Estimate how many GB of residential proxy traffic you need for scraping, monitoring, streaming, or account sessions. Enter your volume and transfer size, and the result updates as you type.

How the proxy bandwidth calculator works
The formula is transfer size × volume per day × days, plus a buffer for retries and overhead. Page size varies by target, client, compression, and whether you load images or browser assets, so measure a real run first.
Example with the scraping defaults: 1,000 pages a day for 30 days at 250 KB is 7.5 GB. A 15% buffer brings it to 8.63 GB, so the suggested allocation is 10 GB.
Measure a browser session with the HAR Analyzer- 01
Measure one real unit
Capture transferred bytes for a representative page, check, stream, or account session.
- 02
Scale by frequency
Multiply that measured transfer by daily volume and the number of active days in your period.
- 03
Keep operational headroom
Add room for retries, redirects, session setup, and normal variation before choosing a plan.
Workload guide
Use the input your workflow can measure
Estimates use decimal units: 1 GB = 1,000 MB and 1 MB = 1,000 KB. Actual billed traffic can vary by provider, protocol, target, and retry behavior.
Proxy traffic per GB
How many requests fit in 1 GB?
The table uses the calculator's default values. They are starting points, not measurements of your target. A page with images or a heavy script bundle can be several times larger.
Use less data
Reduce proxy traffic before you buy more GB
- Block images, fonts, and media in headless browsers when you only need text or prices.
- Use a JSON or API endpoint instead of the full page when one is available and allowed.
- Skip pages that have not changed. Our price monitoring pipeline guide covers change detection and request budgets.
- Cap retries. Every failed attempt through the proxy still uses data.
- Keep sticky sessions only as long as you need them. See how to use residential proxies without breaking sessions.
For streaming or other always-on traffic, per-GB pricing adds up fast. Compare ISP proxies vs residential proxies before you choose.
Data usage calculator FAQ
Answers before you choose a GB amount
How much proxy data do I need?
+
Multiply the number of requests or sessions by the average transferred size, then add a buffer for retries, redirects, authentication, and other overhead. This calculator handles that math for scraping, monitoring, streaming, and account workflows.
How many requests can 1 GB of proxy data handle?
+
Divide 1 GB by the transfer size per request. With decimal units, 1 GB is 1,000,000 KB, so 1 GB covers about 4,000 requests at 250 KB each or 20,000 requests at 50 KB each. Retries and redirects lower that number, so keep a buffer.
Does proxy data include uploads and downloads?
+
Proxy bandwidth normally includes traffic sent and received through the proxy. Use the transferred size from your own test run rather than only the final HTML or file size, because headers, scripts, images, redirects, and uploads can add data.
Why should I add a bandwidth buffer?
+
Real workloads rarely succeed on the first request every time. A buffer covers ordinary retries, redirects, session setup, and response-size variation so the estimate is not sized to a perfect run.
Are residential proxies suitable for streaming?
+
Streaming can consume hundreds of gigabytes quickly. Use the streaming preset to measure the likely bandwidth, then compare bandwidth-priced residential plans with unlimited-bandwidth ISP proxies before choosing.
How can I measure average transfer per page?
+
Run a representative sample and inspect the transferred bytes in your HTTP client, browser network panel, or HAR file. Include successful requests and normal redirects, then use an average rather than the smallest response.
