How much does an audit cost?

[capableweb]

Depends widely on scope, complexity, client and consultancy. Example from Trail of Bits regarding blockchain audits:

    +---------+---------------------------+-------------------------+----------------------+
    | Size    | Small                     | Medium                  | Large                |
    +---------+---------------------------+-------------------------+----------------------+
    | Project | ERCs (20, 71, 4626, ...)  | Standalone arithmetic   | AMM or lending       |
    |         |                           | lib                     | protocol             |
    +---------+---------------------------+-------------------------+----------------------+
    | Pricing | $25k                      | $25-50k                 | $50-100k             |
    +---------+---------------------------+-------------------------+----------------------+
    | Timeline| 1 week                    | 1-2 weeks               | 2-4 weeks            |

It's a bit like asking how much does a vacation cost. It rather depends where you're going and what you're doing.

I'd guess high five figures or maybe low six figures?

Five and six figure vacation costs are why so many security audits are staycations, working from home.
