PROXIES.SX price — drops at volume.
Used to estimate per-transaction Stripe fees.
Illustrative estimate only — runs entirely in your browser, nothing is sent anywhere. Real results depend on churn, refunds, support time, and your actual volume tier. Not a guarantee of earnings.
The math is the easy part — the spread between PROXIES.SX wholesale ($4/GB → $2.40 at volume) and your retail price is your margin. The kit handles everything else: an open-source SDK, a React customer dashboard, and a full Next.js storefront with Stripe and x402 (USDC) billing, on top of a single gateway. No modems, no SIM plans, no rotation infrastructure.
It multiplies the GB you sell each month by your retail price per GB to get revenue, subtracts your wholesale cost ($4/GB on the list tier, dropping to $2.40/GB at volume) and optional Stripe fees (2.9% + $0.30 per order), and shows net profit, net margin %, and your markup multiple. Everything runs in your browser — no data is sent anywhere.
Resellers commonly price at 2–5× their wholesale cost (a directional industry range, not a guarantee). Mobile proxies retail across roughly $2–15/GB depending on brand and country. Your real markup depends on your niche, support quality, and how you position against competitors.
Yes — PROXIES.SX wholesale starts at $4/GB and drops to $2.40/GB at volume, with free endpoints, free rotation, and no monthly fees. GB never expire. Pick your expected tier in the calculator to model margin accurately.
