Data room cost as a share of deal value

For most mid-market transactions a virtual data room is a tiny fraction of the deal value, typically well under 0.1%. A room running a few hundred USD a month over a six-month deal is a rounding error next to a multi-million-dollar transaction. The calculator above turns your own numbers into a percentage and basis points so you can see the ratio for your deal.

Basis points make very small percentages easier to talk about: one basis point is 0.01%, so 100 basis points equals 1%. If a data room costs 0.02% of the deal, that is 2 basis points. Advisers often quote costs this way, so the calculator shows both the percentage and the basis points.

Not necessarily. Because the cost is usually a rounding error against the deal value, the priority is a room that protects the transaction: reliable permissions, an audit trail and a smooth reviewer experience. Paying a little more for the right features is easy to justify when the whole cost is a fraction of a percent of the deal.

No. The total here is simply your monthly price multiplied by the deal length, and the percentage is that total against the deal value you enter. Actual pricing depends on the provider, term and features, so confirm the exact price with the provider before you commit.
