Illustration for How Much Should a Local Business Spend on Google Ads?

There is no correct Google Ads budget that fits every local business. The right number depends on what a customer is worth to you, how often a lead becomes a job and how much competition you face in your area. Anyone who quotes you a flat figure without asking those questions is guessing.

What you can do is work backward from your own numbers. This post shows the method, step by step, so you can set a starting budget and know when to raise or cut it.

Step 1: Know what a customer is worth

Start with your average job. If you do repeat work, count what a typical customer brings over a year. Then take out the cost of doing the job. What is left is the most you could pay to win that customer and still make money.

This is your break-even cost per customer. Your goal is to pay less than this, with room to spare. A business with large jobs can afford a much higher cost per customer than one with small jobs, which is why budgets differ so much between trades.

Step 2: Work out your close rate

Not every lead becomes a customer. Look at your last 20 to 30 leads, from any source, and count how many turned into paid work. Divide jobs by leads. That is your close rate.

If you do not track this today, estimate it honestly and plan to replace the estimate with real numbers after the first month of ads.

Step 3: Turn that into a target cost per lead

Use this formula:

Target cost per lead = break-even cost per customer x close rate

If you can pay a certain amount to win a customer and one in three leads closes, you can pay about one third of that amount for each lead. That is the ceiling. Aim to land well below it so there is profit left.

Step 4: Decide how many leads you want and can handle

Pick a number of leads per month you could actually serve. Ads that bring in more work than your crew can handle just create unhappy customers. Be honest about capacity, and about how fast you answer the phone.

Step 5: Set the daily budget

Multiply the leads you want by your target cost per lead. That gives you a monthly figure. Google works in daily budgets, and its method is to divide the monthly number by 30.4. Google gives the example of $304 a month, which is $10 a day. Google also notes that your daily spend can run up to two times the daily budget on a given day, with a monthly cap of 30.4 times the daily budget. You can read the details in Google’s budget help page.

What the budget has to cover

Enough clicks to learn from. A tiny budget in a competitive market may buy only a few clicks a day, which is too little to see a pattern.
Your area. A wider radius spreads the same money across more towns. Start with the places you most want work.
Management. If an agency runs your account, its fee is separate from what you pay Google. Ask how it is priced before you sign.

How to raise or cut the budget

Do not judge a campaign on the first few days. Give it enough time to collect clicks and a few real leads, then look at cost per lead and cost per customer against your target from Step 3.

Cost per customer under target: raise the budget in steps and watch whether cost per lead holds.
Cost per customer over target: do not cut blindly. Check the search terms report, add negative keywords (see negative keywords explained) and check the landing page first.
No leads at all: check tracking and the page before you blame the market. See what to track in Google Ads.

Common budget mistakes

Setting a budget by copying a number from a blog post, including this one.
Spreading a small budget across many services at once instead of starting with the one that pays best.
Cutting the budget the first week because the numbers look thin.
Never reading the search terms report, so money keeps going to searches that cannot convert.

What you should ask any agency about budget

What is my target cost per lead, and how did you get it?
What is your fee, and is it separate from my ad spend?
Can I see the account and the reports myself?
How will you tell a call from a real job?

Pricing for management depends on scope: how many services, how many locations and how much ongoing work the account needs. That is why we do a review first instead of quoting from a chart.

Questions people ask about Google Ads budgets

Is there a minimum budget for Google Ads?

Google lets you set a daily budget as low or as high as you like. A low budget is not the same as a useful budget. If the money buys only a few clicks a day, it can take a long time to learn anything. Use your target cost per lead from Step 3 to see how many leads a given budget could realistically produce.

Does a bigger budget mean more leads?

Not automatically. A bigger budget gives your ads more chances to show, but if the page, the tracking or the keywords are weak, you simply waste money faster. Fix the basics first, then scale.

Do I pay Google for every click?

For a standard search campaign, yes. You are charged when someone clicks, even if they never call. That is why tracking and negative keywords matter. The amount you pay per click is set by the auction, which you can read about in Google’s explanation.

What if my ads stop showing partway through the day?

That usually means the daily budget was used up. You can raise the budget, narrow the area or cut keywords that do not convert so the same money lasts longer.

A quick worksheet

Fill in these four numbers for your own business before you pick a daily budget:

What a typical job or customer is worth to you after costs.
How many of your last 20 to 30 leads became paid work.
How many leads a month you can handle.
How many days you will give the campaign before reviewing.

If you cannot answer the second one, that is your first task. Start counting leads and jobs today so that the numbers are real when you review the ads.
