Pay per GB proxies
How gigabytes are counted when you pay per GB, the 低价线路 and 优质线路 prices, how to estimate your volume and when leasing an IP costs less.
Monthly Residential Proxies vs Pay-As-You-Go: Cost by Usage
Work out which billing model costs less for your own traffic, using one break-even calculation instead of headline prices.
How the two billing models differ
A monthly plan sells a fixed GB allowance for one billing period at a fixed price. Whether you use all of it or a tenth of it, the price is the same. The terms on unused GB (reset, expiry or rollover) are set by each provider, so read them on the plan page before you buy.
Pay-as-you-go sells GB that are deducted only as traffic passes through the proxy. You top up when you need more, and nothing is charged for a month in which you send no traffic.
Monthly plan and pay-as-you-go side by side
| Item | Monthly plan | Pay-as-you-go |
|---|---|---|
| What you pay for | A GB allowance for one period | Only the GB you use |
| Unused GB | Depends on the provider; often lost at renewal | Stay on your balance until used (no expiry at Proxy302) |
| Suits | Steady jobs that use the whole allowance every month | Uneven, seasonal or still-unknown traffic |
| Main risk | Paying for GB you never use | Higher price per GB than a large bulk plan |
| Number to compare | Plan price ÷ GB you actually used | Price per GB × GB you actually used |
General description of the two billing models; the Proxy302 column entries come from the Proxy302 product facts file, checked 10 November 2026. Check any other provider's plan page for its own terms.
The break-even point in one line
Divide the plan's price per GB by the pay-as-you-go price per GB. The result is the share of the allowance you must use for the plan to cost the same. If the plan works out at US$1.00 for each GB and pay-as-you-go at US$1.50 for each GB, the break-even is 1.00 ÷ 1.50 = 67%: use less than two thirds of the allowance and pay-as-you-go is cheaper.
The table below runs the same arithmetic on a hypothetical plan: US$100 for 100 GB a month, with unused GB lost at renewal. The pay-as-you-go column uses US$1.50 per GB, the Budget line price at Proxy302.
Worked example: hypothetical 100 GB plan vs US$1.50 per GB
| Item | Hypothetical plan (US$100, 100 GB, expires) | Pay-as-you-go at US$1.50/GB |
|---|---|---|
| Use 100 GB | US$100.00 | US$150.00 |
| Use 67 GB | US$100.00 | US$100.50 |
| Use 60 GB | US$100.00 (US$1.67 per used GB) | US$90.00 |
| Use 30 GB | US$100.00 (US$3.33 per used GB) | US$45.00 |
| Use 10 GB | US$100.00 (US$10.00 per used GB) | US$15.00 |
Hypothetical plan chosen only to show the arithmetic; it is not any provider's price. Pay-as-you-go column = GB used × 1.50, the Proxy302 Budget line per-GB price checked 10 November 2026.
How to decide before you pay
Step 1
Run a small test of your real job and note how many GB it used. Scale it to a month: test GB × number of runs. The estimation guide shows how, with three worked examples.
Step 2
Write down your lowest and highest month, not the average. A plan has to be sized for the high month, and the gap to the low month is what you would pay for and not use.
Step 3
Apply the break-even line: if your low month is below the break-even share of the allowance, choose pay-as-you-go. If every month is above it, a plan can be cheaper.
How Proxy302 bills traffic
Proxy302 rotating residential traffic is bought by the GB and the purchased traffic has no expiry, so there is no monthly allowance to lose. The Budget line is US$1.50 per GB for any amount from 1 GB, with package sizes priced per GB at 50 GB US$1.42, 100 GB US$1.35, 300 GB US$1.20 and 500 GB US$1.124. The Premium line is US$5 per GB, with 50 GB at US$4.74, 100 GB at US$4.50 and 300 GB at US$4.25.
There is no free trial; the smallest purchase is 1 GB. Which line fits is a separate question, covered in the line comparison.
FAQ
Is pay-as-you-go always cheaper than a monthly plan?
No. If you reliably use most of a monthly allowance and the plan's price per GB is lower, the plan can win. Pay-as-you-go wins when usage varies or you do not yet know your volume.
What happens to unused GB on a monthly proxy plan?
That is set by each provider: some reset the allowance every period, some allow rollover. Read the plan page before buying. At Proxy302 the traffic you buy has no expiry.
How do I compare a plan with pay-as-you-go fairly?
Compare the cost per GB you actually used, not the headline price: plan price ÷ GB used, against pay-as-you-go price per GB.
Is there a free trial for residential traffic at Proxy302?
No. The smallest purchase is 1 GB of rotating residential traffic.
