How Much Should You Actually Spend on Google Ads in 2026?

It's the first question almost every business owner asks us: how much do I need to spend on Google Ads? The honest answer is that the budget should be an output of your goals — not a number you pluck out of the air.

Start with what a customer is worth

Before you think about budget, work out two numbers: what a lead is worth to you, and how many leads turn into customers. If a customer is worth $2,000 and one in three leads converts, you can afford to pay a lot more per lead than a business selling a $50 product.

Once you know those numbers, your budget becomes a maths problem rather than a guess. You're simply buying leads at a price that leaves you a healthy margin.

A realistic starting point

For most service businesses, we usually suggest starting somewhere between $1,500 and $3,000 a month in ad spend. That's enough to gather meaningful data quickly without burning budget before the campaigns have learned.

Give it room to learn

Google's algorithm needs conversions to optimise. Starve a campaign and it never gets the data it needs to improve. We'd rather run one well-funded campaign than five underfunded ones competing for scraps.

The right budget isn't the biggest one — it's the one that buys leads profitably and lets the campaign learn.

The bottom line

Spend enough to generate real data, tie every dollar to a tracked outcome, and scale up only as the return proves out. Do that and Google Ads stops being a cost and starts being an engine.
