Your Numbers

Profitability Check

What Should Your Google Ads Budget Actually Be?
There's no one-size-fits-all budget. It depends on your industry's cost per click, your conversion rate, and how many customers you actually need to hit your growth goals. A roofer's budget math looks nothing like a pest control company's.
Most home service businesses in a metro market like Portland need at least $1,500–$3,000/month to generate consistent leads. Below that, you don't get enough data to optimize, and Google's algorithms can't reliably learn what's working in your account.
The real question isn't "how much should I spend" — it's "how much can I spend profitably?" That's what this calculator answers. Work backward from your goal, plug in your real numbers, and the math tells you whether the campaign supports itself.
The biggest waste isn't spending too much — it's spending on poorly built campaigns that leak budget on bad keywords, weak landing pages, and missing conversion tracking. A $2,000 budget on a great campaign will outperform a $5,000 budget on a mediocre one every time.
