Static ISP Pricing

How Graduated Proxy Pricing Works

Graduated tiers lower the rate on later units only. How to calculate the real per-IP cost and avoid buying inventory you won't assign.

Each tier applies only to the units inside it

Graduated pricing does not retroactively lower the cost of earlier IPs when you cross a tier boundary. The lower rate applies only to the units within the new tier. A 100-IP order is not 100 × $1.40.

5-24      2.00 each
25-49     1.73 each after 24
50-99     1.50 each after 49
100-199   1.40 each after 99
200+      1.30 each after 199

The actual 100-IP total is 24×2.00 + 25×1.73 + 50×1.50 + 1×1.40 = $167.65. The last IP costs $1.40. The batch does not.

The same logic applies at every boundary. 200 IPs totals $307.55, not 200 × $1.30. 500 IPs totals $697.55.

Active-IP cost reveals the real number

An order may have 100 IPs paid but only 81 accounts actively assigned. The useful cost is $167.65 ÷ 81 = about $2.07 per working IP, not $1.40. That gap matters when sizing the next order.

A useful annotation on any order record looks like this:

requested=100; assigned=81; spare=19; total=167.65; active_ip_cost=2.07; owner=agency_ops

The owner field is there because spare IPs become contested the moment two teams both need them.

Crossing a tier boundary to lower the marginal rate increases total spend

If you need 90 IPs, ordering 100 to reach the $1.40 tier saves $0.10 on one IP and costs an extra $1.40 for a slot you may never assign. Run the total both ways before placing the order.

The only time crossing a boundary makes sense is when you have genuine demand for the additional IPs and the blended cost per active IP drops below what the smaller order would cost per active IP.

Static ISP bills IPs, not bandwidth

Static ISP proxies charge per assigned IPv4 address with unlimited bandwidth for normal use. That is the opposite of Volume Residential ($0.89/GB) and Premium Residential ($5.00/GB), which bill per transferred byte.

A browser job that pulls 30 GB through a static IP does not move the bill. But a workflow that only needs 10 GB/month and pays for 20 idle IPs is still over-provisioned — the waste shows up in active-IP cost, not in a bandwidth line item.

Static ISP suits workloads that need the same exit IP across multiple sessions: regional dashboards, account operations, browser profiles where the destination recognizes the address. The finite pool of routable addresses is tracked in the IANA IPv4 address space registry. Rotating residential makes more sense for one-off requests where exit consistency has no value.

Graduated pricing FAQ

Does graduating to a higher tier lower the price of earlier IPs? No. The lower rate applies only to the units inside the new tier. Earlier IPs stay at the rate of their own tier.

What is active-IP cost and why does it matter? Active-IP cost is the total order price divided by the number of IPs actually assigned to tasks. A 100-IP order with 81 assigned accounts costs $167.65 ÷ 81 = about $2.07 per working IP, not $1.40.

Does static ISP pricing include bandwidth? Static ISP bills assigned IPs, not bandwidth. Bandwidth is unlimited for normal use, unlike Volume or Premium Residential which bill per gigabyte.

When does buying into a higher tier make sense? Only when you have genuine demand for the additional IPs. Buying extra IPs to reduce the marginal rate increases total spend and leaves spare slots sitting idle.
