Proxy pricing is difficult to compare because providers sell different products with different billing units. A residential gateway priced per gigabyte, a static ISP address priced per month, and a shared datacenter bundle priced by pool size are not substitutes.
Core rule
Compare the same proxy type, quantity, location, session model, and time period.
The cheapest plan is the one with the lowest cost per useful result—not necessarily the lowest number printed beside “per GB” or “per IP.”
The main proxy pricing models
| Model | Common products | Best for | Main hidden cost |
|---|---|---|---|
| Per GB | Residential, mobile, rotating datacenter | Variable or short projects | Retries, page size, targeting, and unused subscription traffic |
| Per IP | ISP/static residential, dedicated datacenter | Stable, recurring sessions | Minimum quantity, rental term, and unusable IPs |
| Monthly bundle | Shared datacenter pools, platform plans | Predictable recurring usage | Unused capacity and auto-renewal |
| Pay as you go | Residential, mobile, rotating gateways | Irregular usage | Higher unit rate at low volume |
| Unlimited or unmetered | Dedicated datacenter/ISP or high-volume residential | Traffic-heavy workloads | Fair-use, concurrency, speed, or target restrictions |
| Per port or gateway | Backconnect and reseller products | Teams managing many sessions through one endpoint | Port count, concurrency, and rotation controls |
Per-GB pricing
Per-GB plans meter traffic transferred through the proxy. Providers can count request and response bytes, so a page with large images, video, fonts, or repeated retries costs more than a small API response.
Worked example: small PAYG purchase
DataImpulse lists a $5 introductory residential purchase at $1/GB. A 5 GB project therefore starts at $5. If only 3 GB produces useful results and 2 GB is consumed by retries or unnecessary assets, the effective cost is:
$5 ÷ 3 usable GB = $1.67 per usable GB.
Worked example: subscription utilization
Webshare currently displays 10 GB at $27.50, or $2.75/GB. If the subscriber uses only 4 GB before renewal:
$27.50 ÷ 4 used GB = $6.88 per used GB.
Worked example: larger minimum with non-expiring balance
PacketStream charges $1/GB but requires a $50 purchase. A user who needs 5 GB still funds $50. The unused balance does not expire, so the economic question is whether the remaining 45 GB will be useful later.
Per-IP pricing
Per-IP plans charge for a fixed number of endpoints over a term. This model is common for ISP and dedicated datacenter proxies. It can be economical for high bandwidth because traffic is often unmetered, but the buyer carries route-quality and inventory risk.
Worked example: static ISP tier
Webshare lists 250 static residential IPs at $0.30 each per month:
250 × $0.30 = $75/month.
If only 200 routes meet the location and target requirements, the effective cost becomes:
$75 ÷ 200 usable IPs = $0.375 per usable IP-month.
Worked example: longer dedicated term
IPRoyal advertises dedicated private proxies from $1.39 per IP per month on a 90-day term. A one-IP purchase at that monthly equivalent represents roughly $4.17 over 90 days, before taxes or product-specific changes.
Monthly platform plans
A platform plan can include more than proxy bandwidth: multiple proxy types, targeting, API access, support, dashboards, and data-extraction tools. The correct comparison is not only cost per GB; it is whether those features reduce engineering and operating cost.
SOAX lists a Starter plan at $90 for 25 GB, or $3.60/GB. The $90 minimum makes it unsuitable for a tiny experiment but potentially reasonable for a team that uses the included platform and proxy-type access.
Unlimited and unmetered pricing
“Unlimited bandwidth” means the provider does not bill by traffic under the stated plan. It does not remove every limit. Review:
- Port speed.
- Concurrent connections.
- Connection rate.
- Target or domain restrictions.
- Fair-use policy.
- Rental duration.
- Acceptable-use rules.
ProxyScrape’s shared datacenter plan, for example, lists 1,000 proxies and 250 GB for $25/month, while its unlimited-residential product uses a different flat-rate product and pool. Compare the exact product rather than treating every “unlimited” label as equivalent.
Targeting and feature surcharges
Advanced targeting can increase the rate or reduce available inventory. Potential cost drivers include:
- State, city, ZIP, ASN, or ISP targeting.
- Longer sticky sessions.
- Dedicated or exclusive IPs.
- Mobile carrier or OS filters.
- Higher concurrency.
- Sub-user management.
- Premium or filtered pools.
A provider can have the lowest base rate but a higher final rate after the required targeting and product options are selected.
Traffic expiry and renewal
| Plan behavior | Benefit | Risk |
|---|---|---|
| Traffic does not expire | Good for intermittent use | Balance is still wasted if the provider or route type does not fit |
| Monthly traffic resets | Predictable recurring allocation | Unused traffic is lost at renewal |
| Auto-renewing per-IP plan | Keeps stable routes assigned | Renewal continues until cancelled |
| Fixed term | Can lower the unit rate | Locks the buyer into the route inventory and provider |
Taxes, currency, and checkout totals
Public tables may exclude VAT, sales tax, payment fees, or currency conversion. A price shown in dollars can be billed in another currency or include tax only at checkout. Store the final invoice total when comparing providers.
How to calculate effective proxy cost
Effective cost per usable gigabyte
Total plan cost ÷ gigabytes that produced usable output.
Effective cost per accepted request
Total plan cost ÷ successful target requests.
Effective cost per usable IP
Total plan cost ÷ IPs that passed location, ASN, reputation, and target checks.
Effective cost per completed record
Proxy cost + retries + engineering time ÷ valid records delivered.
The last formula is usually the most useful for a real data workflow. A higher proxy rate can be cheaper when it reduces retries, engineering effort, and unusable output.
Pricing decision table
| Workload | Usually compare first | Reason |
|---|---|---|
| One-time 5 GB regional test | Low-minimum PAYG residential | A monthly commitment may waste budget |
| Stable long browser session | Per-IP ISP proxy | Continuity matters more than pool size |
| High-bandwidth target that accepts hosting ASNs | Dedicated datacenter per IP | Unmetered traffic can be cheaper |
| Small client setup test | Free shared datacenter tier | Validates authentication and integration at no purchase cost |
| Large variable collection | Volume residential plan | Per-GB rates fall with commitment |
| Multi-product team | Platform bundle | Central controls may reduce operating cost |
Before buying
Record the full price—not only the advertised unit
- Proxy type.
- Billing unit.
- Minimum purchase or plan size.
- Traffic expiry or renewal date.
- Location and targeting fees.
- Protocol and authentication.
- Rotation and sticky-session controls.
- Bandwidth and concurrency limits.
- Tax and payment total.
- Measured usable output from a small test.

FAQ
What does per-GB proxy pricing mean?
The provider charges for traffic transferred through the proxy gateway. The price can include both request and response data, so page size, retries, and unnecessary assets affect the bill.
What does per-IP proxy pricing mean?
The provider charges for a fixed number of proxy IPs over a rental period. This model is common for dedicated datacenter and ISP proxies and can include unlimited bandwidth under plan terms.
How do I calculate the effective cost of a proxy plan?
Divide the total plan cost by the useful output: usable gigabytes, accepted requests, stable IPs, completed records, or successful test sessions. Headline unit price alone does not show effective cost.
Does non-expiring traffic make a plan cheaper?
It can when usage is intermittent because unused balance remains available. It does not help when the provider lacks the targeting, session behavior, or target-specific performance the workflow needs.
Are unlimited proxy plans really unlimited?
Unlimited usually means no per-GB charge. Providers can still impose speed, concurrency, port, fair-use, target, and acceptable-use restrictions.
Should I choose the cheapest provider or the cheapest proxy type?
Choose the cheapest proxy type that fits the target and session first. Then compare providers within that product class using the same quantity, location, protocol, and billing period.
