What You Need For An Accurate Result

The calculator is only as good as the data you input. To build an accurate budget so need hard data for:

  • Average CPC (Low & High): The range can be quite high for some terms and ad planning tools like Google Ads Keyword Planner can be inaccurate, but getting an idea of what to expect can help project. Then you can see what cost point would be ideal and limit your CPC to that max. Ideally this will be somewhere between the high and low.
  • Monthly Keyword Volume: Don’t just go for volume, make sure the traffic is closely related to your core service offering. The further you stray, the more irrelevant clicks you will get and this will lower ROAS.
  • Click-Through Rate (CTR): Industry averages are a good guide, but the final CTR will depend on how good your ad assets are.
  • Conversion Rate: Before starting a campaign its important to perform conversion rate optimization. The higher your conversion rate the higher your ROAS. Remember you are paying for each visit to your site whether they convert or not, so its in your best interest to make sure your conversion rate is performing well.
  • Average Lead Value: The greater the lead value the more CPC you can afford. You may choose to view lead value as a single event, or a lifetime value. Either way you will need the math between the number of leads, and their value to work in your favor, being more than the cost of ads.

How to Calculate an Effective PPC Budget

To get an accurate forecast, you need to pull data from the source. While third-party tools like SEMrush or Ahrefs provide excellent competitive insights, the most direct path is through the Google Ads Keyword Planner.

1. Finding Average CPC and Volume

Look for “Avg. monthly searches” to see total demand. For pricing, focus on “Top of page bid (low range)” and “Top of page bid (high range).”

  • The Low Range represents what you might pay to appear at the bottom of the first page, or in the least competitive auctions/off hours/odd times.
  • The High Range is what it takes to secure a spot no matter the competition. (This comes with the caveat that your ad copy and landing page experience most be good. You can’t spend your way to showing. If your ad is irrelevant, or the user experience is poor, Google will show someone else.

A Note on Estimates: These numbers are based on past data and are projections, not guarantees. Real-world costs fluctuate based on your specific targeting, time of day, and how well your landing page actually answers the user’s search query.

2. Defining Your Lead Value

Whether your business relies on a one-time purchase or a multi-year retainer, you must know what a new customer is worth.

  • For E-commerce: Use your Average Order Value (AOV).
  • For Service Providers: Use the initial contract value or the Lifetime Value (LTV) if you have the data to support it.

3. Setting Realistic Benchmarks (CTR & Conversion)

If you are starting from scratch, use a 2–5% range for both Click-Through Rate (CTR) and Conversion Rate.

  • If your CTR is below 2%, your ads aren’t resonating.
  • If your Conversion Rate is below 2%, your website is likely losing the traffic you just paid for.

What Impacts Your CPC (And How to Lower It)

You don’t always have to pay the “market rate” for a click. If you find your CPC is too high, it’s usually a symptom of one of three things:

  • Competition: Broad keywords like “Emergency Plumber”) will always cost more longer tail keywords like “24hr plumbing near me. You will want to check who shows up on Google when you type in your keywords. The more businesses bidding on a term, and the bigger they are, the more you can expect the cost to be greater. The good news is, the competition is likely not bidding on everything they could be and finding the under represented auctions and unique angles is the best way to lower your CPC.
  • Quality Score: Google rewards relevance. If your ad, your keywords, and your landing page aren’t perfectly aligned, Google charges you a “bad experience tax” in the form of higher CPCs.
  • Targeting Breadth: Trying to show up for everyone, everywhere, is the fastest way to drain a budget.

How to lower CPC:

Narrow your geographic focus, use more specific “long-tail” keywords, and obsess over your landing page experience to improve your Quality Score.

FAQs

Yes, but shrink your target/scope. If you can’t afford the whole city, own three zip codes. If you can’t afford 100 keywords, dominate five. A small, focused budget that wins is better than a large, thin budget that loses.

ROAS is a simple math problem: lower your costs or increase your lead value. Between the two, its usually a conversion problem. If your site doesn’t have the foundational strucutre, and your service the value convert, no amount of ad optimization will save the math.

Increase your relevance. Google rewards the best answer. If your ad and landing page perfectly align with the search intent, your Quality Score goes up and your costs go down. It’s a technical game of removing friction.

There’s no magic number, only strategy. A few popular methods for finding the right budget are:

  • Goal-Oriented: Work backward from your revenue targets to find the required spend.
  • Percentage of Revenue: Simple and scales with growth, but it’s reactive and ignores new opportunities
  • Data-Driven Forecasting: This is what the calculator above and this page is all about.

It depends on your timeline and your math.

The Aggressive Sprint: If your monthly budget is spread so thin that you can’t compete daily, don’t. It’s better to go aggressive for a shorter window, generate immediate results, and reinvest that revenue into the next round.

The Waiting Game: If you aren’t in a rush and the daily math doesn’t work, save your budget. Pool it for a month so that when you run a test, you have enough budget to compete.

The Timely Push: If there is a seasonal surge or a rush initiative, always go aggressive.

A “good” budget is simply one that allows you to capture enough market share and get enough data to make informed decisions.

If your average CPC is $5.00 and you only budget $10.00 a day, you’re getting two clicks. You’ll be waiting months to see if your strategy even works. A healthy budget is one that generates enough daily volume to prove (or disprove) the model quickly so you can pivot and optimize.

The average return on ad spend (ROAS) is 2. That being said ROAS fluctuates by industry with some having less margin while others have greater room to run. A good mark to hit is a ROAS of 4+. Something to note is that the length of the customer’s buyer’s journey, could be longer than 30 days. You should look at ROAS over a length of time that reflects how long a user would take to research and make a decision.

The industry standard for measuring paid advertising success is the return on ad spend (ROAS). This is for every dollar you spend on ads how many do you get back? A good ROAS is anything above 4.

That being said not every business can clearly attribute revenue to ads. Other methods of defining success are:

  • A maintainable or attractive cost per lead
  • Getting X amount of leads a month
  • Reaching X amount of people

We work closely with clients to ensure goals are being met. This includes a monthly report that breaks down key metrics with next steps.

There is no minimum budget for starting a paid search campaign. That being said, you can definitely be limited by budget. A good starting point is to determine how much it would cost to be competitive, estimate how many leads it could generate, and if the cost per lead is feasible to maintain.
