How to Choose the Right Residential Proxy Plan (Bandwidth vs Requests vs IPs)

Why proxy pricing feels confusing

Residential proxy providers usually sell access in one of three units:

• Bandwidth (GB)
• Requests
• IPs (static/dedicated)

Choosing the wrong unit can make costs explode, especially during cold-start when you are still tuning retries and parsers.

Model 1: Bandwidth-based plans (GB)

Best for: large pages, media-heavy sites, browser automation, unpredictable payload sizes.

Pros

• Simple: you pay for data transferred.
• Works for both API-style scraping and full browser pages.

Cons

• Wasteful if you download heavy assets you do not need.
• Retries directly increase cost.

How to estimate GB

1. Sample 100 successful responses.
2. Compute average response size (including headers).
3. Multiply by request volume.
4. Add retry budget (for example 20–50% during early tuning).

Model 2: Request-based plans

Best for: high-volume, small payload endpoints (search results HTML, JSON endpoints, price checks).

Pros

• Predictable if your pages are small.
• Encourages optimized fetching (no unnecessary assets).

Cons

• Some workflows need multiple requests per “page view” (API calls, pagination).
• If your success rate is low, retries still hurt.

How to estimate requests

Break your workflow into steps:

• Listing page requests
• Detail page requests
• API calls per item
• Login / token refresh calls

Then multiply by:

• Items per day
• Countries
• Concurrency

Model 3: IP-based plans (static ISP / dedicated)

Best for: allowlisting, long sessions, accounts that cannot tolerate identity switching.

Pros

• Stable identity and predictable routing.
• Easier to debug.

Cons

• Limited scale per IP.
• Not ideal for broad geo coverage.

A simple decision framework

Choose your plan based on two questions.

1) Are you using headless browsers or downloading heavy pages?

• Yes → start with bandwidth.
• No → request-based may be cheaper.

2) Do you need stable identity for minutes to hours?

• Yes → consider static ISP / IP-based.
• No → rotating residential is fine.

Common sizing mistakes (and how to avoid them)

1. Ignoring retries
2. Not controlling assets
3. Over-rotating
4. Using residential for easy targets

Summary

Pick the pricing unit that matches your workload shape. During cold-start, prioritize predictability and fast iteration over chasing the cheapest theoretical CPM.
