The Real Cost of a Single Manuscript Edit
Most writers treat editing as a single purchase. The reality is a four-stage process, and the cost compounds at every stage.
Developmental editing - structure, character arc, plot logic, pacing - runs $0.07 to $0.12 per word from a qualified editor. On a 90,000-word novel that is $6,300 to $10,800, with a turnaround of four to eight weeks.
Line editing - sentence-level clarity, flow, voice consistency - runs $0.04 to $0.08 per word. Same manuscript: $3,600 to $7,200. Three to six weeks.
Copy editing - grammar, punctuation, continuity - runs $0.02 to $0.04 per word. $1,800 to $3,600. Two to four weeks.
Proofreading: $0.01 to $0.02 per word. $900 to $1,800. One to two weeks.
A complete editorial pass on a single novel: $12,600 to $23,400, and up to five months of waiting.
That number surprises most writers. What surprises them more is learning that developmental editing - the most expensive stage - is also the most sensitive to the condition the manuscript arrives in. An editor who receives a draft with pattern-level problems that could have been caught algorithmically will spend the opening hours of their engagement cataloguing surface issues rather than engaging with the deeper work. The deeper work is what you are paying for.
AI analysis tools now occupy the early portion of this pipeline. Pattern-level problems - repeated sentence structures, overused phrases across chapters, dialogue that fails to differentiate speakers, pacing inconsistencies that only surface across three hundred pages - are detectable before a human editor is ever involved. Tools like Draft Sentinel run this kind of analysis directly against your manuscript in minutes, not weeks.
This does not change what a skilled developmental editor brings. The artistic response, the market awareness, the judgment that comes from thousands of hours reading - none of that is reproducible.
But it changes when it makes sense to bring a human editor in. And it changes what the early passes of feedback should cost.
The question for any writer approaching editorial work is not "AI or human." It is "what stage is my manuscript at, and what does that stage require?" Getting that sequence right is where the real money is saved.
