How much do Google Ads cost? Budgets, CPC and cost per lead

KKahu team·Updated 1 Oct 2026·7 min read

Quick answer

Google Ads has no set price. You pay when someone clicks, and the price is set by an auction for each search. Competitive services in busy areas cost more per click than niche ones. Set a budget you can sustain for at least a month, track leads and sales rather than clicks, and use your own results to decide what to spend.

How the auction works

When someone searches, Google runs an auction among advertisers targeting that search. Your position and price depend on your bid and on how relevant your ad and landing page are. A better page can mean paying less for the same spot.

What makes clicks expensive

Services with high customer value, such as legal, finance and home repairs.
Busy cities where many businesses compete.
Broad keywords that attract searchers who are only browsing.
Ads and pages that do not match the search closely.

Setting a budget

1Estimate the click priceGoogle’s Keyword Planner shows rough ranges for your area. Treat them as a starting guess.
2Estimate conversionIf one in ten visitors enquires, ten clicks buy one lead. That gives you a rough cost per lead.
3Compare with customer valueIf a lead costs more than you can make from it, narrow the keywords or improve the page.
4Commit for a monthShorter tests rarely produce enough data to judge.

Frequently asked questions

What is the minimum budget for Google Ads?

There is no official minimum. The practical minimum is enough to get a meaningful number of clicks in a month for your keywords.

Is Performance Max cheaper than Search?

Not necessarily. It spreads budget across many placements, which can lower click costs but also lead quality.

Do I pay if nobody clicks?

For standard Search ads, you pay per click. Some other campaign types can charge differently.
