Work out what you're actually asking for.

Because any number it gave you would be made up. Two projects with identical tick-lists can differ several times over depending on what your content is like, what your existing systems are, and how quickly decisions get made, none of which a form knows. We quote after a conversation, at a fixed price agreed before work starts. A calculator that guessed would only be useful for making us look cheap until the real number arrived.

It writes down what you're asking for. The reason three quotes come back four times apart is almost never that one agency is greedy. It's that all three were asked a different question, and each filled the gaps with their own assumptions. Send the same brief to all three and the numbers become comparable.

They're what we would budget for each piece of work, and the tool shows the days each item adds so the total is something you can check rather than take on trust. They're a statement about how we work, not a survey of the industry. Nobody has measured that, and we're not going to pretend otherwise.

Use the table under the brief. Type each agency's name and fill in what they quoted: price, time, whether design and words are included, hosting, support, who owns the result, payment terms. Anything they didn't say is marked "Ask them". We don't score the quotes, because what matters most is your call, but blank cells are usually where the real differences hide.

Yes, that's rather the point. Copy it and send it to whoever you like. A business that knows what it's asking for gets better work from everyone, including from the agency that isn't us.
