Why do proxy prices vary so much?

At the same 100-IP quantity and 30-day billing period, Bright Data lists $100 for bright-data-datacenter-shared-100-ips and $170 for bright-data-datacenter-dedicated-100-ips. Oxylabs lists $100 for oxylabs-datacenter-shared-pay-per-ip-100-ips and $155 for oxylabs-datacenter-dedicated-pay-per-ip-100-ips. The published dedicated premium is therefore $70 at Bright Data and $55 at Oxylabs. Bright Data source · Oxylabs source, both retrieved 2026-07-25T15:31:32Z

Proxy prices vary because the purchased dimension varies. The strongest explanation holds the provider, product type, quantity and billing period constant, then changes one published property. It does not attribute the gap to quality, success rate or internal vendor costs that the dataset never measured.

Shared and dedicated inventory have different published prices

The opening pairs isolate sharing status better than a market-wide low-to-high range:

The Bright Data rows are bright-data-datacenter-shared-100-ips and bright-data-datacenter-dedicated-100-ips. The Oxylabs rows are oxylabs-datacenter-shared-pay-per-ip-100-ips and oxylabs-datacenter-dedicated-pay-per-ip-100-ips. All four are monthly, per-IP rows retrieved from vendor pricing on 2026-07-25T15:31:32Z. Bright Data source · Oxylabs source

The table proves that both vendors publish a higher checkout for the dedicated variant at that quantity. It does not prove that either premium improves results on a buyer’s target. No comparative target test exists in plans.json.

Commitment changes the effective monthly amount

Ping Proxies provides a clean one-IP commitment comparison. ping-proxies-datacenter-monthly costs $2.50 for 30 days. ping-proxies-datacenter-quarterly costs $6.75 for 90 days, equal to $2.25 per 30-day month. ping-proxies-datacenter-annual costs $24 for a year, equal to $2 per month when divided across 12 months. Vendor pricing, retrieved 2026-07-25T17:42:41.156Z

Relative to twelve monthly purchases at the one-IP entry price, the annual row lowers the normalized amount from $30 to $24, a $6 difference. The lower monthly equivalent requires the buyer to commit the full $24 checkout, so it should not be compared with the $2.50 monthly row as if both require the same cash or duration.

Geography can change the same provider’s ladder

ProxyScrape’s one-month dedicated datacenter rows publish $9.50 for five United States IPs on proxyscrape-dedicated-us-1mo and $10.45 for five Brazil IPs on proxyscrape-dedicated-br-1mo. The Brazil checkout is $0.95, or 10%, higher while IP count and billing period stay fixed. Vendor pricing API, retrieved 2026-07-25T16:33:08.221Z

That result supports a geography-specific price difference for those two rows. It does not support a rule that every country carries a 10% premium. The same vendor ladder must be recomputed at the requested country and quantity. Vendor pricing API, retrieved 2026-07-25T16:33:08.221Z

Unlimited plans price capacity instead of transferred GB

ProxyScrape’s one-day unlimited residential ladder charges $190 at 100 Mbps on proxyscrape-unlimited-residential-1d-100mbps and $1,102 at 1,000 Mbps on proxyscrape-unlimited-residential-1d-1000mbps. The checkout rises by $912, or 5.8 times, while the published throughput tier rises by 10 times. Vendor pricing API, retrieved 2026-07-25T16:33:08.221Z

Neither price should be divided by guessed traffic to create a per-GB rate. These rows sell a fixed access period and a throughput tier without a GB meter. The useful comparison is required throughput at the same duration, not an assumed month of continuous maximum utilization. ProxyScrape product page, retrieved 2026-07-25T16:33:08.221Z

Volume discounts change the unit rate, not necessarily the checkout

Within Bright Data’s shared datacenter ladder, 10 IPs cost $14, 100 cost $100, 500 cost $475 and 1,000 cost $900. The unit rate falls from $1.40 to $0.90 as the checkout rises from $14 to $900. The plan rows are bright-data-datacenter-shared-10-ips, bright-data-datacenter-shared-100-ips, bright-data-datacenter-shared-500-ips and bright-data-datacenter-shared-1000-ips. Bright Data source, retrieved 2026-07-25T15:31:32Z

Using the $0.90 rate to price a 10-IP purchase would produce $9, a checkout Bright Data does not publish for that tier. A lower unit rate belongs to its required quantity and cannot be detached from the larger total. Bright Data source, retrieved 2026-07-25T15:31:32Z

The honest explanation is row-specific

When two prices differ, first align proxy type, billing unit, quantity and period. Then compare sharing, geography, throughput, commitment, expiry and other published dimensions one at a time. The matched examples above explain exact differences without inventing a universal markup.

If no published dimension isolates the gap, the data can report the difference but not its cause. “More expensive” is a computed price result. “Better,” “more reliable” or “worth it” requires target evidence that this dataset does not contain.
