What Affects Your Rate

Turnaround Time

Rush jobs and same-day delivery significantly increase the per-word or hourly cost. Standard turnaround is 3–5 business days.

Document Type

Heavy academic, technical, or STEM manuscripts cost more than general fiction or basic blog posts due to specialized vocabulary and citation requirements.

Scope of Work

Pure proofreading — catching surface-level typos, spelling, and grammar — is priced lower than copy editing, which involves style consistency and structural clarity.

Professional Experience

Certified professionals and industry veterans charge near the top of industry benchmarks, as tracked by the Editorial Freelancers Association.
