Data room cost by deal size: a USD budgeting guide

Five hundred dollars or fifty thousand. Both are honest answers to “what does a data room cost”, and that spread is the reason most pricing pages are so unhelpful.

The price of a room is less about the software and more about the shape of your deal: how many documents, how many outside users, how many months. So rather than list vendor price sheets, this guide starts from the deal and works back to a budget. All figures are in US dollars and are indicative; confirm current pricing with the provider before you commit.

What should you budget for your size of deal?

Here are the bands we see most often, based on deal type, the usual size of the room and how long it typically stays open.

Notice that the last row looks expensive for its file count. Property files are full of scanned leases, surveys and plans, which inflate page counts and storage, and that matters a great deal if you are billed per page or per gigabyte.

How are data rooms priced?

Four models cover almost every provider. Many vendors mix two of them.

Flat monthly subscription. You pay a fixed fee per month for a room or a set number of rooms, usually with generous or unlimited users. Easy to forecast, and the risk is simply that the deal runs long.

Per user. A fee per seat per month. Common with general file-sharing tools that also sell data room features. Fine for an internal team; it gets awkward when 200 bidder users each need a seat.

Per page. The traditional enterprise model. You pay for every page uploaded, sometimes with a minimum. A 5,000-page room at a few tens of cents a page is affordable; a 200,000-page scanned archive is not.

Per storage, often per gigabyte. Similar logic to per page but measured in data volume. Video, CAD drawings and high-resolution scans make this expensive.

Which model suits you depends on what your room looks like. Here is a quick matrix.

What do providers publish in USD?

Most enterprise rooms do not publish prices; they quote per project after a call. The providers below do list a starting price in our data. Treat these as entry points: the cheapest tier rarely includes every feature, and prices change.

A caution on the cheaper end: Onehub, Box and ShareFile are general-purpose file-sharing platforms. In our data they do not offer a built-in deal Q&A workflow, which is one of the features most sell-side processes rely on. Comparing them with deal-focused rooms on price alone is misleading. Our pricing page lays the full field side by side.

What do three real-world budgets look like?

Abstract bands are useful. Worked examples are better. These three are composites of typical deals, not specific clients.

A Series A raise: about 600 USD

A software company with 2 million USD in annual revenue is raising its Series A. The room holds around 180 files: financial model, board minutes, cap table, customer contracts, employment and IP assignment agreements. Twelve investor users from five funds look at it.

On a flat plan at 149 USD a month, a four-month process costs about 600 USD. On a per-user plan at 45 USD a seat, twelve outside users plus three insiders for four months would be 2,700 USD, which is why per-seat pricing suits internal teams better than investor processes.

A founder selling a 25M USD business: about 4,500 USD

An adviser runs a two-round sale with eight first-round bidders, narrowing to three. The room peaks at 3,500 files, mostly native PDFs and spreadsheets, and stays open for six months including confirmatory diligence. A flat or quoted per-project mid-market room typically lands at 3,000 to 6,000 USD. The quiet risk here is the extension: if signing slips, every extra month is billed.

A private equity carve-out: 25,000 USD and up

A fund is buying a division of a listed company. The seller’s adviser hosts 15,000 files across finance, IT separation, real estate and employees, for 250 users at seven bidders, with a clean team folder for pricing data. An enterprise room quoted per project, with dedicated support and a long term, will generally run well into five figures.

The cheapest room is rarely the one with the lowest monthly fee. It is the one whose pricing model matches the shape of your deal.

Which line items push the bill up?

Most budget overruns come from the same handful of items. Ask about each on your first call.

• Extension months. Many quotes assume a fixed term. Ask what each additional month costs and whether the rate rises.
• Page or storage overages. If you are on a capped plan, find out the overage rate before the scanning starts.
• Archive and export. Some providers charge for an encrypted copy of the room after close, often delivered on USB media or as a download. Confirm the format and fee.
• Onboarding and setup. Bulk upload, indexing and redaction services can be billed separately on enterprise plans.
• Additional rooms. A second room for a clean team or a parallel financing can count as a new project.
• Premium features. Single sign-on, API access, advanced analytics or AI tools are sometimes limited to higher tiers.

Do regulatory timelines affect what you pay?

They can, because they stretch the term. In the United States, deals above the Hart-Scott-Rodino size threshold must be notified to the antitrust agencies and generally cannot close until an initial 30-day waiting period ends, longer if the agencies issue a second request. If your room stays open through that window so both sides can reference documents, budget for those months.

Regulated targets add their own costs. A healthcare company holding protected health information may need a vendor willing to sign a business associate agreement under HIPAA, which narrows the field and can move you to a higher tier. In our data, Box and Citrix ShareFile list HIPAA among their certifications.

How can you cut the cost without cutting corners?

You do not need the most expensive room to run a clean process. A few habits keep the bill sensible.

1. Prepare before you open. Build the index and clean the files locally, then upload. Paying for the room while you are still collecting documents is the most common waste.
2. Convert and compress. Searchable PDFs at sensible resolution use a fraction of the storage of raw scans.
3. Use the trial properly. Most providers in our ranking offer a free trial; Ellty’s is 14 days. Use it to load a real folder and test permissions, not just to click around.
4. Negotiate the end, not just the start. Extension rates and archive fees are easier to fix before signature.
5. Close promptly. Once the deal completes, export the archive and shut the room down.

Is a cheaper room ever the wrong choice?

Yes, in three situations. If you expect hundreds of bidder users, a platform that charges per seat will cost more than a flat-fee deal room. If buyers’ counsel will expect a formal Q&A log, a file-sharing tool without one creates manual work that costs more in adviser hours than the software saved. And if the target holds regulated data, a lower tier without the right certifications or contractual terms is a false economy.
