How to Work Out Proxy Server Cost Before You Buy

What a Proxy Server Costs per Month in 2026

Your proxy server cost is set by the meter, not the logo on the invoice. Rotating residential traffic has a median entry rate of $4.00 per GB across 21 providers; mobile sits at $4.50 per GB, ISP proxies at $2.70 per IP a month, and datacenter traffic around $0.60 per GB. A 30 GB monthly workload therefore lands between roughly $30 and $135 before surcharges, which is why you estimate from your own workload instead of the headline rate.

Proxy Server Cost by Type: The 2026 Ranges

Almost every public price list collapses into one of five meters. Knowing which meter you are being sold tells you more about your eventual bill than comparing two vendors’ entry prices side by side.

Per-IP pricing: you buy addresses, not volume

Per-IP billing is flat. Webshare sells 100 datacenter proxies for $2.99 a month, which works out near $0.0179 per proxy at scale; its static residential line starts at $6 a month for 20 proxies, or $0.30 per IP. Oxylabs bills ISP proxies daily at a rate equal to $1.50 per IP on its three-IP Starter tier, falling to $1.10 per IP on Enterprise, with bandwidth unmetered under fair use. For a 20-profile team, 20 ISP addresses at the $2.70 median is $54 a month with no per-gigabyte anxiety.

Per-GB pricing: you buy volume, not addresses

Per-GB billing scales with traffic, so the same plan can cost $9 or $900 depending on what your profiles actually load. The spread is wide: IPRoyal quotes $7.35 per GB for a single gigabyte and $5.51 at 10 GB; Decodo charges $4.00 per GB pay-as-you-go or $11.25 a month for 3 GB ($3.75/GB); Byteful lists $3.25 per GB at 10 GB and $2.75 at 100 GB, with a further 10% off quarterly and 20% off annual billing; Bright Data starts at $8.00 per GB on list and falls to $5.00 per GB on its $1,999 monthly plan. At the bottom, Evomi advertises $0.99 per GB from 15 GB on non-expiring traffic. To see how those tiers stack against each other, compare residential proxy prices line by line rather than by the first number on the page.

How the Meters Work Under the Hood

Converting gigabytes into requests

A gigabyte price means nothing until you translate it into the unit you actually consume. Take a 500 KB page at $1 per GB: that is about $0.0005 per request, or roughly $0.50 per 1,000 requests. Most pages pull fonts, images and analytics scripts on top of the HTML, so your real average is heavier than the document itself. At $4.00 per GB, 30 GB of traffic costs $120 and covers roughly 60,000 requests at that 500 KB average — enough to price a month of work, if you know your page weight.

Why a commitment can cost more than pay-as-you-go

Monthly plans only win above their break-even volume, and unused commitment does not roll over. Bright Data’s $499 plan buys about 71 GB at $7.00 per GB; at list rate it only beats the $8.00 pay-as-you-go price above roughly 62 GB a month, or about 125 GB while its time-limited discount halves the rate. Burn 30 GB and you have paid $499 for 30 GB — an effective $16.63 per GB.

Expiring traffic works the same way. Evomi’s $49 plan buys 100 GB at $0.49 per GB, but that traffic expires each month. Use 40 GB of it and your effective rate is $1.23 per GB, which is worse than paying $39.60 for the same 40 GB at its $0.99 non-expiring rate. The break-even is roughly 49.5 GB. Oxylabs runs the same logic from the other direction: plan amounts feed one shared credit balance at $6.00 per GB, and unused credit expires at the end of each cycle unless you upgrade.

Surcharges that break the headline rate

Three costs hide behind the sticker. First, targeting: city, ZIP and ASN selection can be billed as a multiplier — Evomi’s documentation bills it at up to 15×, even though its marketing page has described targeting as free. Second, concurrency: Oxylabs drops its ISP allowance from 100 concurrent sessions per IP to 10 once 50 GB per IP has been used in a billing cycle, which throttles throughput you already paid for. Third, tax and refund terms: several vendors quote prices before VAT, and Oxylabs self-service purchases are non-refundable.

Why Proxy Cost Scales With Profile Count, Not Headcount

If you run one browser for one person, proxy cost is a rounding error. At 20 client profiles it becomes a line item you forecast. Agencies managing client accounts, social media managers switching between brand logins, sellers with several storefronts and QA teams testing as different regions all hit the same arithmetic: each profile needs its own exit IP, locale and session state, so the proxy bill scales with profiles rather than with people.

The real decision is fixed address versus rotating. A logged-in dashboard that stays open all day belongs on a per-IP connection: the address should not change mid-session, and per-GB billing punishes a tab that polls in the background for eight hours. A task that touches many unrelated public pages belongs on per-GB rotating traffic, because you need address variation more than a flat rate.

Rank on cost per usable request, not per gigabyte. A $2/GB route that fails a fifth of its attempts costs more per page than a $4/GB route that completes them, because failed requests are still billed. Advertised pool sizes are ceilings, not verified counts — the industry-median advertised pool is 54M IPs against vendor claims of 400M+ and 175M+ — so test success rate on your own targets before signing a commitment. Providers ranked by price per GB gives you a shortlist to test.

One thing price cannot settle: authorisation. Where a platform caps how many accounts one person may hold — Amazon’s approval route for an additional seller account, Meta’s Business Manager roles for agencies — the answer is the platform’s own process, not a cheaper proxy.

What a 20-Profile, 30 GB Month Actually Costs

Here is the same workload priced through every route, using published rates:

The gap between $29.70 and $240 for identical volume is the whole argument for pricing from your workload. A separate 2026 comparison put 25 GB at about $24.75 on the cheapest published residential route against roughly $200 at Bright Data’s list rate — an eight-fold difference on the same traffic.

How to Estimate Proxy Server Cost in Six Steps

1. Count concurrent sessions, not accounts. Twenty saved profiles that run three at a time need three proxy connections, not twenty. That concurrency figure drives per-IP purchases and hits provider session caps.
2. Measure gigabytes per session for one week. Open the browser’s network panel on a representative profile, record the transfer size, then multiply by sessions per month. Do not guess from page counts.
3. Convert to requests when comparing tools. A 500 KB average at $1 per GB is $0.50 per 1,000 requests; at $4 per GB it is $2.00 per 1,000. Recalculate with your own page weight.
4. Match the meter to the job. Long logged-in sessions go on per-IP ISP addresses; broad public browsing goes on per-GB rotating residential; region testing can often share one static address per region.
5. Apply the surcharges before you compare. Add VAT, add targeting multipliers if you need city or ASN selection, and check whether plan credit expires at the end of the cycle.
6. Add 30–50% headroom and read the refund terms. Bandwidth estimates undercount background polling and failed retries, and Webshare’s 2-day refund on low usage is worth more than a marginal rate difference.

Common Mistakes That Inflate the Bill

• Buying the largest plan for the per-GB rate. A 1,000 GB commitment at $2.00 per GB is $2,000 spent to move 30 GB. Pay-as-you-go wins below break-even volume every time.
• Forgetting that traffic expires. A $0.49 per GB plan that resets monthly can cost more per usable gigabyte than a $0.99 non-expiring wallet if you under-use it.
• Assuming targeting is included. Geo, city and ASN selection is a billed feature at several providers, and multipliers stack on the base rate.
• Ignoring concurrency caps. A per-IP plan that drops from 100 to 10 sessions per IP after 50 GB is throttled exactly when the workload is heaviest.
• Ranking on sticker price only. Two providers at $3 per GB are not comparable if one needs two retries per successful request.
• Budgeting without the KYC clock. Onboarding vetting is standard now, and a two-business-day review can push a project start past its deadline.

Where Send.win Fits in Your Proxy Budget

Send.win is a browser profile manager, so the proxy question arrives with the profile question. Each isolated browser profile carries its own cookies, storage, sessions, fingerprint settings and proxy, which means one profile can sit on a client’s ISP address while another uses bundled residential bandwidth — and you can attribute every gigabyte to a client instead of to a shared endpoint.

Both plans bundle proxies rather than selling them separately. Pro at $19 a month includes 20 residential proxies and 5 GB of bandwidth across 150 saved profiles and 6 seats; Team at $49 a month includes 20 proxies and 20 GB across 500 profiles and 16 seats. Extra bandwidth is $6 per GB on either plan, bringing your own HTTP/SOCKS5 proxy costs nothing extra, and up to 50 profiles can run at once on both plans — which matters if you already hold a per-IP contract and only need the profile layer.

The honest trade-off: at low monthly volume, bundled bandwidth removes a vendor relationship and a second invoice, while timezone, locale, WebRTC and geolocation follow the proxy’s exit IP automatically so you are not paying twice for region matching. At high volume a dedicated per-GB contract will beat $6 per GB, and bring-your-own is the cheaper route. Profiles run either in the Sendwin Browser desktop app for Windows, macOS and Linux, or in the cloud browser on Send.win’s Helsinki server for a teammate on any device. Note that profiles are driven by people in the app — there is no API, SDK or headless mode on any plan — so budget for seats rather than for a scripting stack. The mechanics of per-profile routing are covered in proxy browser explained.

Frequently Asked Questions

How much does a proxy server cost per month?

Entry pricing in 2026 clusters around $0.60 per GB for datacenter traffic, $2.70 per IP for ISP proxies, $4.00 per GB for rotating residential and $4.50 per GB for mobile. A 30 GB monthly workload therefore runs from about $30 to $135 depending on type. Plan commitments, targeting surcharges and taxes push the final invoice higher than the advertised entry rate.

Why are residential proxies priced per GB but datacenter per IP?

Datacenter addresses are cheap to host and sold as inventory, so the natural unit is the address itself. Residential traffic is sourced through consenting peers, and the provider pays for the bandwidth leaving those devices, so the natural unit is volume. Per-GB pricing passes that metering cost to you; per-IP pricing assumes your traffic is light enough not to matter.

What is the cheapest proxy type for long-running sessions?

A per-IP ISP or static residential address with flat bandwidth, because an open session that sits idle or syncs in the background is billed the same whether you use one gigabyte or twenty. Rotating residential is the wrong meter for a session that stays open all day — you pay per gigabyte for traffic a flat IP rate would absorb.

How do I convert a per-GB price to cost per request?

Divide the rate by the number of requests a gigabyte covers. At a 500 KB average, one gigabyte is roughly 2,000 requests, so $1 per GB works out to about $0.0005 per request and $0.50 per 1,000; at $4 per GB the same page costs about $2.00 per 1,000. Recalculate with your own average page weight, because images and scripts are usually the bulk of it.

Is a $0.50 per GB residential proxy too cheap to trust?

Treat it as a warning sign rather than a bargain. Residential rates stabilised in 2026 after several years of steep declines, and grey-market entry pricing under $0.50 per GB is now widely described as a red flag because the sourcing behind it is rarely disclosed. Ask how the addresses are obtained before you route client logins through them.

Do proxy providers offer free trials?

Terms vary and some claims conflict across sources, so read each vendor’s own page. Oxylabs replaced timed trials with a one-time $5 welcome credit that expires once a normal billing cycle renews, Decodo’s trial requires a card, and Webshare offers a short refund window if usage stays low. None of these replaces measuring your own bandwidth first.

What extra fees raise the real proxy bill?

VAT on quotes that exclude it, targeting multipliers for city or ASN selection, concurrency reductions after a bandwidth threshold, and plan credit that expires at the end of each cycle. Non-refundable self-service purchases and KYC review delays add risk rather than line items. Add all four before you compare two quotes.

How much bandwidth does one account session use?

It depends almost entirely on what loads in the tab: images, fonts and background polling dominate, not the HTML. Measure a representative session in the browser’s network panel for a week and multiply, rather than estimating from page views. Then add 30–50% headroom for retries and the scripts you did not notice.
