Proxy cost calculator
Last checked: 2026-11-06
Enter a price per GB, the data you need and your plan terms to see your real monthly cost and cost per successful GB. Use one currency throughout. Take prices from our price database or your own bill.
How this works
We divide the data you need by the success rate to get the GB billed. We assume failed traffic is billed, which is the cautious view. If your provider does not bill failures, enter 100%.
The plan minimum buys its value in GB at your price per GB. Anything above that is charged at the overage rate. With no plan minimum, you pay the price per GB for every GB billed.
With the example numbers, 100 GB at 90% means 111.11 GB billed. The 50 plan covers 100 GB, because 50 / 0.5 = 100. The other 11.11 GB costs 0.60 each, or 6.67. The total is 56.67, so each successful GB costs 0.57, not the 0.50 on the price list.
What to check before you trust the result
- Plan minimums hurt at low volume. If you enter a plan of 54 at 0.54 per GB but need only 20 successful GB at 80%, you pay 54 and use 25 GB. That is 2.70 per successful GB.
- Overage rates are often unpublished. Many pages do not state one. Ask, or enter the plan rate and treat the result as a floor.
- Some prices are per IP. This tool is for per-GB plans. See datacenter vs ISP cost for why per-IP plans do not compare.
- Credits can expire. See Oxylabs pricing explained for one example.
Lawful use depends on the place, the data and the site's terms. This is not legal advice. We have not tested these services, and the tool makes no claim about any provider's success rate. For API plans, use the scraping API cost calculator.
