In short
The word review covers four different services, and their prices do not sit on one scale. English correction is charged per word and starts at $91 (Springer Nature) or $0.0425 per word (Editage); manuscript editing rises to $0.065 per word at Editage and $312 for Springer Nature's Gold tier, and the subject-expert tier reaches $0.2 per word and $1,545. Statistical review is not priced per word at all: it is charged per hour, from $115 to $345 depending on who signs it, according to Georgetown's public biostatistics fee schedule updated in July 2026. Full consultancy is priced per project: Omega Statistics publishes from $2,000 for the analysis behind a dissertation's results chapter alone. The spread is that wide because at the first two tiers nobody opens your data, and every price here was checked on each provider's own site in September 2026.
You have three quotes in your inbox and they look nothing alike. One says $180. Another says $900. The third says from $2,000, let's talk. All three use the word review, all three promise a better manuscript, and none of them explains the difference except through the length of its adjective list. The decision in front of you is not which one is cheapest: it is which of the three fixes the thing you are actually going to be rejected for, because paying for the wrong tier does not get you halfway there — it leaves you exactly where you started with less money. What follows are the prices each provider publishes on its own site, with the source for every figure, and above all what does and does not get opened at each tier.
Four different services under one name
The word review covers four things that have little in common. English correction fixes grammar, spelling and consistency: someone reads your text and makes it readable. Manuscript editing goes one tier up and touches structure, flow and fit with the journal, but it is still reading text. Statistical review opens the analysis and checks whether what you report follows from what you did. And full consultancy does not hand you a document: it hands you decisions and someone who answers for them.
The most informative part of a quote is not the number, it is the unit. The first two services are billed per word; the last two per hour or per project. That is not a commercial convention, it follows from the fact that in copy-editing the work scales with the text and in statistics it does not. Two hundred words of Results can hide four weeks of work, and eight thousand words of Introduction hide none.
Hold that distinction and the ranges stop looking arbitrary and start being comparable. The prices below will change; the way to read them will not.
English correction: $91 to $340, and the clock rules
Springer Nature Author Services lists its Silver tier from $91: it corrects spelling, grammar and punctuation and polishes English usage. Editage charges its Advanced Editing from $0.0425 per word, which for an 8,000-word manuscript comes to roughly $340. Enago puts firm numbers in its calculator: 3,000 words of Copy Editing cost $174 with a six-day turnaround and $225 if you want it in twenty-four hours.
Scribbr is the most transparent of the four because it publishes the whole table instead of a starting-from figure. For 8,000 words its Spanish site charges €100 at one week, €140 at 72 hours and €180 at twenty-four hours, plus a fixed €20 handling fee. Same text, same editor, same work: the 80% gap between the first row and the last is purely urgency.
What you buy at this tier is a text that reads like English. What you do not buy is anyone looking at your numbers, and that deserves saying without drama: it is exactly what these services sell, and they do it well. If language is why you were rejected — and it happens more often than people admit in public — this is your tier, and paying for the one above will not fix it better, only more expensively.
Manuscript editing: you are paying for structure, not spelling
The second tier does not cost double everywhere, but you feel it. Editage sells its Premium Editing from $0.065 per word, 53% above its Advanced tier, and adds improvements to logic and structure, detailed revision comments, free re-editing for 365 days and a cover letter. Springer Nature goes from $91 to $312 between Silver and Gold, which it describes as a more detailed edit with greater emphasis on the overall flow. Enago charges $252 for 3,000 words of Substantive Editing at six days, and $432 if you want it in twenty-four hours.
Above that sits a third level where the price triples at Editage and quintuples at Springer Nature. Editage calls its Scientific Editing Pro a service from $0.2 per word, pairing an editor from your field with a peer reviewer from top journals and giving deep feedback on the science. Springer Nature sells Scientific Editing from $1,545, which by its own description bundles the Gold edit, a developmental edit, a quality assurance pass and a three-to-six-page report. AJE publishes a Presubmission Review at $289 and a Pre-Submission Peer Review from $500.
The reason for the jump is simple and honest: at the top tier they put someone from your field on it, and that hour is scarce. But look closely at what is promised even there — comments, judgment, scientific feedback. None of those service pages mentions recomputing your statistics, and not out of stinginess: it is not the category. A scientific editor will tell you your discussion does not hold up on those results; they will not tell you that your F(2, 87) = 4.31 does not produce the p value you wrote, because they never went and checked.
Statistical review: per hour, which is why nobody quotes it per word
The cleanest figures here do not come from a company, they come from universities that publish their fee schedules. Georgetown's biostatistics department, with rates updated in July 2026, charges $115 an hour for a master's-level biostatistician, $192 for a doctoral-level one and $230 for a director when the request comes from inside the university; for external clients, those same three categories cost $138, $274 and $345 an hour.
The University of Florida's biostatistics consulting lab publishes a similar scale: $200 an hour for a doctoral-level statistician on internal projects up to a hundred hours, $180 beyond that, and $300 for external clients. In the private sector, Omega Statistics charges $175 an hour to researchers and $250 to companies, and Professional Statistical Services publishes $125 an hour for students and $125 to $150 for researchers.
Put the four sources together and a defensible range for September 2026 falls out: an hour of doctoral-level statistician runs from $175 to $300, and what moves it inside that band is who signs it and who they work for, not how much text you send. That is why nobody prices this per word. Word count does not predict the work: the state of your data does, along with how many decisions have to be justified afterwards.
Translated into a real job: the Results section of an ordinary paper, with data already cleaned, is not two hours. It is usually a long day, and that is where the several hundred euros on any serious quote come from. The breakdown by type of job, what pushes the price up and what should make you suspicious, is in what statistical analysis for a thesis costs.
Full consultancy: you are buying the decision and whoever answers for it
Omega Statistics has the rare virtue of publishing prices chapter by chapter. A sample size calculation, from $1,000. Methodology, from $3,500. Results, from $2,000 for analysis only and from $5,000 with full service. A statistical analysis plan for clinical research, from $15,000. That last figure is not a typo: a clinical trial analysis plan is a regulatory document and is priced like one.
My own tiers, so they sit in the same table and you can compare without going to look for them: a closed analysis plan before you collect data from €300, a specific analysis run and reported in APA 7 from €500, a point-by-point response to reviewers from €800, and the complete statistical section of a Q1 paper from €1,500.
What separates this tier from the ones above it is not the amount of work, it is whose problem it becomes when something fails. With English correction you buy a document; with consultancy you buy someone defending the methodological decision when a reviewer attacks it. Before you sign anything in this band, ask two questions: who signs it by name, and what happens if a reviewer knocks the analysis down. If the answer to the second is we'll talk about it then, the price did not include what you thought it included.
Why the same job costs $91 or $15,000
How many words. This only really governs the first two tiers, and it has a ceiling: Editage asks you to contact customer service above 18,000 words, and Springer Nature quotes custom above 40,000, or above 18,000 for Scientific Editing. Past that point you are negotiating again, exactly as you would at the lower tiers.
How much of a hurry. This is the most expensive variable in a quote and the least examined. The same 3,000 words of Copy Editing at Enago go from $174 to $225 when you drop from six days to one, a 29% increase; the same words in Substantive Editing go from $252 to $432, a 71% increase. At Scribbr, the same 8,000 words go from €100 to €180 between one week and twenty-four hours, an 80% increase. You are paying almost double for a week you nearly always had when you started.
Who touches it. At Georgetown, the same hour costs $115 or $192 depending on whether the biostatistician holds a master's or a doctorate. At Florida, $200 or $300 depending on whether you are internal or external. When a quote does not say who does the work, that is precisely the variable being kept out of sight.
What is promised afterwards. Editage includes free re-editing for 365 days in its Premium tier; Enago sells that same cover separately as Edit Unlimited at $0.02 per word, and charges $60 for a cover letter and $99 for a three-in-one check pack. AJE charges journal formatting from $75 and a cover letter from $40. Almost everything that looks like a price is a price plus a list of things that fall outside it, and that outside list is where it is decided whether the number was cheap.
What none of these prices buys you
None of the prices above includes recomputing your statistics, and the providers say so themselves without hiding it. Paperpal advertises grammar and tone, plagiarism detection, paraphrasing, citation generation and more than thirty pre-submission checks indexed to the requirements of over 1,500 journals. Writefull describes itself as helping you write, paraphrase and copyedit. Neither claims to recompute a p value from its degrees of freedom or to check a reference against a bibliographic database, and that is not a flaw: it is their category, and in their category they are good. Comparing them to a statistical review is like comparing a copy-editor to an auditor.
The fine distinction is in the citations, because that is where the name misleads most. Scribbr sells a citation editing service, charged per source, which by its own description makes sure the right information is there and that capitalization, punctuation and the layout of the reference list follow the style guide. Whether a reference is correctly formatted and whether the reference exists are two different questions, and only the second one saves you from a published correction. I go through it in full in checking your references before you submit.
That empty band is what Previum occupies: it recomputes p values from the degrees of freedom in code, checks reported effect sizes against the F or t you reported yourself, and verifies references one by one against eight databases (Crossref, OpenAlex, Semantic Scholar, PubMed, DOAJ, arXiv and OpenLibrary). There is a free Basic version and a Professional version, and you can see exactly what the report contains in the sample report before uploading anything.
With the limit stated plainly, because the sentence matters: this is not peer review. It is a self-assessment by the author of their own manuscript before submission. And it does not replace a copy-editor if your problem is the English, nor a statistician if the problem is the design. If what worries you is where you are going to be rejected before you decide which tier to spend on, this is where manuscripts usually break.
Frequently asked questions
Why is English correction billed per word and statistical review per hour?
Because in one the work scales with the text and in the other it does not. A copy-editor reads every one of your words, so counting them predicts their day well. A statistician might spend twenty minutes on the correlation table of an 8,000-word manuscript and four days on a structural equation model that occupies two paragraphs. The word count carries no information, so the honest unit is the hour. When someone quotes you statistical review per word, either they are not going to do it or they are going to do it superficially.
Does a $0.2-per-word service review my analyses?
By the provider's own description, not in the sense of recomputing them. Editage describes Scientific Editing Pro (from $0.2 per word) as an editor from your field paired with a peer reviewer giving deep feedback on the science, and Springer Nature describes Scientific Editing (from $1,545) as a developmental edit with a quality assurance pass and a three-to-six-page report. Neither page mentions checking any calculations. That is expert judgment on your argument, which is worth a great deal and is often exactly what you are missing. But it is not the same as checking that the F you report and the degrees of freedom beside it produce the p value you wrote.
How much does urgency actually add?
With public numbers: at Enago, 3,000 words of Copy Editing go from $174 at six days to $225 at one day, 29% more, and the same words in Substantive Editing go from $252 to $432, 71% more. At Scribbr, 8,000 words go from €100 at one week to €180 at twenty-four hours, 80% more. Urgency is the most expensive line in the quote and almost always the most avoidable one: it comes from starting late, not from the manuscript. If the deadline is the journal's, so be it; if it is yours, it is the easiest saving on the page.
Is a presubmission review the same thing as peer review?
No, and no serious provider claims it is. AJE sells its Presubmission Review at $289 and its Pre-Submission Peer Review from $500: these are reports you commission on your own manuscript, before submission, and you decide what to do with the result. Peer review is organized by the journal, with reviewers you do not choose and who can reject you. The first is preparation and the second is the exam, and confusing the two in a cover letter reads very badly.
These are international providers. Do the prices hold if I publish in another language?
The English correction ones obviously do not. The statistical review ones do, because the hourly rates published by Georgetown, Florida, Omega Statistics or Professional Statistical Services do not depend on the language of the manuscript: they depend on who signs it and how many hours it takes. If you publish in your own language, the language tier drops out of your budget and what is left in plain sight is usually the real problem, which is the analysis and how it is reported.
If my problem is the analysis, is the expensive editing tier worth it?
Almost never. Paying $1,545 for scientific editing on a manuscript whose problem is a misspecified model hands you a better-written text with the same error inside it, and now harder to spot because it sounds convincing. The order that works is the reverse: first make the numbers right, then make the text read well. You are not paying a language editor to notice that you confused eta squared with partial eta squared, and they will not notice.
Do you know which tier you actually need?
The three quotes at the top were not expensive, mid-range and cheap: they were different services wearing the same name. If English is your problem, the $91-to-$340 tier solves it and you need nothing more. If what will not hold is the analysis, no amount of editing will fix it, and the unit stops being the word and becomes the hour. The pricing page lists my own tiers with the detail of what each one includes, from the automated report through to the complete statistical section of a Q1 paper, so you can compare them against the figures in this article with both numbers in front of you.
See the tiers and what each includes →Keep the reading rule, because it outlives the prices: the unit tells you what you are buying. Per word, someone reads your text. Per hour, someone opens your analysis. Per project, someone takes on the decision and defends it afterwards. And none of the three, on its own, checks that the numbers you wrote are the ones your data produce: that is asked for separately, and it is worth asking for before you pay for any of the other three. Every figure in this article was checked on each provider's own site in September 2026 and will change; the way to read them will not.
