How to Brief a Marketing Budget When You Don't Have Historical Data

Every new brand or new market eventually runs into the same problem: how do you plan a marketing budget without any historical performance to base it on?

Use category benchmarks as a starting anchor

Even without your own data, reasonable industry benchmarks for cost-per-click, conversion rate, and typical customer value provide a grounded starting estimate rather than a pure guess.

Size the initial test to get a real answer

A test budget too small to generate meaningful data wastes the opportunity to actually learn something. It's often better to run a shorter, well-funded test than to stretch a small budget over a longer period without ever reaching a clear conclusion.

Build in room to be wrong

The first budget in a new market should be treated as a hypothesis, not a commitment. Planning explicit checkpoints to reassess — rather than locking in a full quarter's spend upfront — keeps the plan adaptable to what's actually being learned.
