🧠 How Much Should You Spend on Google Ads? Use Our Budget Calculator to Find Out

If you’ve ever asked yourself, “How much should I spend on Google Ads?” — you’re not alone. Whether you’re just starting out or scaling an existing campaign, setting the right budget is key to getting a steady flow of leads without wasting money.

That’s why we built this simple, smart Google Ads Budget Calculator — to help service-based businesses figure out how much they should invest based on real numbers from their own business.

💸 Why Budgeting Isn’t One-Size-Fits-All

Most Google Ads budgets are either:

• Too low to drive enough leads

• Or too high without enough clarity on the return

The right budget depends on your goals, your close rate, your average cost per click, and how many leads you already get from other sources (like LSA or referrals).

Our calculator helps you take all of that into account.

🔧 What This Calculator Does

This calculator answers one simple question:

“How much do I need to spend on Google Ads to hit my monthly revenue goals?”

It works by reverse-engineering your budget from:

• 🧑‍🔧 How many jobs you want per month

• 🔁 Your lead-to-booking rate

• 💵 Your average CPC (cost per click)

• 🎯 Your conversion rate

• 📥 Any other lead sources like LSA or referrals

📊 How to Use the Calculator

1. Enter how many booked jobs you want each month

2. Add your booking rate (your close rate on leads)

3. Plug in how many leads you’re already getting from other sources

4. Add your average CPC and conversion rate (you can estimate if unsure)

💡 The calculator will then tell you:

• How many leads you need from Google Ads

• Your estimated CPA (cost per acquisition)

• Your recommended monthly budget

⚡ Example

Let’s say you want 200 booked jobs a month, and you close 80% of your leads.

That means you need 250 leads.

If you already get 50 leads from LSA, you need 200 from Google Ads.

Now, if your CPC is $35 and your conversion rate is 20%, your CPA is $175 — and you’ll need a $35,000 budget to hit your goals.

🧠 Pro Tip: Budgeting Isn’t the Whole Story

Of course, budget is just the beginning. If your campaigns are poorly structured, even the perfect budget won’t save you from high CPAs and low lead quality.

That’s where we come in.
