Client hire rate is the share of a client's past job posts on Upwork that ended in at least one hire, shown in the client panel of every job post so that freelancers and agencies can judge whether the client actually hires.
Upwork computes the figure from the client's history on the platform: the number of jobs posted against the number that led to a contract, shown as a percentage alongside the count of jobs posted, hires, open jobs and total spend. A client who has posted ten jobs and hired on six shows 60%. A brand-new client shows no rate at all, and Upwork's Help Center treats a low rate as a flag for freelancers rather than a judgment on the client. The exact way Upwork counts a post with several hires, or a post that is still open, is set by Upwork and not published.
The rate is the single most useful line in the client panel. Most job posts on Upwork never lead to a hire, so a client with a high rate is worth more Connects than one who posts and abandons. Read with client spend, payment verification and the average rate paid, it tells a freelancer whether the post is a real purchase or a survey of the market.
It is a client metric and nothing else. It is not the freelancer's win rate, which Upwork shows only to the freelancer in their own proposal statistics, and it does not predict how a particular contract will go. A 100% client who pays badly is still a bad client.

This term describes Upwork's own rules or product rather than a figure the index measures; the pages that do carry live figures are the stats and rate pages.
