Serper has no subscription: you buy credit packs (Starter $50 / 50k = $1.00 per 1k · Standard $375 / 500k = $0.75 · Scale $1,250 / 2.5M = $0.50 · Ultimate $3,750 / 12.5M = $0.30), valid for 6 months; new accounts get 2,500 free queries (not subtracted). Formula: months a pack lasts = min(6, credits ÷ monthly burn); USD / month = pack price ÷ months it lasts. If your burn is low, a big pack's cheaper per-1k rate is wasted because unused credits expire. The pricing page counts 1 credit per query; some request options (e.g. more than 10 results per query) may consume more credits, so check your dashboard and raise "credits per query" if needed. Rate limits: 50 / 100 / 200 / 300 queries per second by pack. Prices exclude sales tax / VAT / GST.

How it works
- Do Serper credits expire?
- Yes. Credits are valid for 6 months. If your monthly burn × 6 is lower than the pack size, the leftover credits expire, so a smaller pack can be cheaper per month.
- How many credits does a query use?
- The pricing page treats 1 query as 1 credit. Some options (such as more than 10 results) may use more; check your dashboard and adjust the credits-per-query input.
- Is any data uploaded?
- No. These calculators and QR codes run in your browser.
- Can these AI prices change?
- Yes. Vendors change list prices often. Edit the $/1M or plan fields, and confirm on the official pricing page before you budget.
- Is usage data uploaded?
- No. Token and subscription math runs in your browser. Nothing is sent to a server.
