Monthly proxy plans print a lower rate per gigabyte because they are a commitment. Pay as you go prints a higher rate because you can stop. The plan that looks disciplined in a screenshot is the expensive one if half the gigabytes die on the renewal date.
A worked shape, not a universal winner
Take Decodo’s public residential numbers. Pay as you go is $4 per GB plus VAT. Fifty gigabytes on that meter is $200 plus VAT. Their 50 GB subscription is cited at $3 per GB, $150 plus VAT. The subscription wins by $50 if you use the 50 GB. If you use 30, you paid $150 for $120 of pay-as-you-go traffic. The subscription lost.
IPRoyal’s answer to that loss is non-expiry. The rate is higher at the start, $7.35 at 1 GB in the citations we use, and the leftover is supposed to remain. That feature is worth money only when you would otherwise have burned unused gigabytes. Verify the sentence on their page. Terms move.
Coupons are a third plan
Bright Data’s list pay-as-you-go is $8. A coupon often displays $4. If you model the company at $4 forever, you modeled a promotion. Write the list, write the coupon, write the date you saw it.
