How do you calculate cost per acquisition?

Divide your total marketing and sales spend over a period by the number of new customers you won in that period. Spend $2,000 on ads and SEO and land 10 new customers, and your CPA is $200. Include the cost of the channel, not just the ad budget, for a true number.

What is a good cost per acquisition for home services?

It depends on what a customer is worth. For a $200 cleaning job a CPA of $30 to $60 is healthy. For a $9,000 HVAC install you can pay $200 to $500 and still profit. The rule is simple: CPA should sit well below the profit from one job, or the lifetime value of a repeat customer.

What is the difference between CPA and CPL?

CPL, cost per lead, is what you pay for someone who contacts you. CPA, cost per acquisition, is what you pay for someone who actually buys. CPA is always higher because not every lead books. The gap between them is your booking rate, which a fast callback and a clear site shrink.

How do I lower my cost per acquisition?

Close more of the leads you already pay for. Answer faster, fix a slow or confusing site, and follow up on estimates. SEO and reviews lower CPA over time because organic leads have no per-lead cost. Cutting ad spend without fixing conversion just gives you fewer leads at the same CPA.

Cost per acquisition, the number that decides if your marketing works

Cost per acquisition (CPA) is what you spend to win one paying customer: total marketing and sales spend divided by new customers. Spend $2,000 and land 10 customers, your CPA is $200. The number only matters next to one other figure — what a customer is worth to you.

We run a cleaning company and an HVAC company on our own marketing stack, so we watch CPA every month. The honest version of this page: most service businesses don't have a spending problem, they have a closing problem. Lowering CPA usually means converting the leads you already pay for, not buying more.

The formula, with a real example

CPA = total spend ÷ new customers

Google Ads ......... $1,200

SEO / content ...... $ 600

Yard signs + flyers $ 200

Total spend ........ $2,000

New customers ...... 10

CPA = $200 per customer

Count the full cost of each channel — software, fees, the freelancer's invoice — not just the ad budget. A CPA that ignores half its costs lies to you. Track it monthly and per channel so you can see which source is cheap and which is quietly bleeding.

What a "good" CPA looks like by trade

Recurring cleaning ($150–$250/job)

$30–$60 CPA

Low job value, but customers repeat for months or years, so a higher CPA still pays once you count lifetime value. Recurring revenue is what makes the math forgiving.

Plumbing / electrical service call

$50–$150 CPA

Mid-ticket, often one-off, sometimes urgent. Speed of response moves this CPA more than ad spend does — the first business to answer usually wins the job.

HVAC install / roofing ($8k–$15k)

$200–$500 CPA

High ticket, so you can pay real money to acquire and still profit. These buyers research for weeks, which is exactly why content and reviews lower the cost.

How to lower CPA without spending more

→ Answer faster. The first business to call back wins most service jobs. A missed call is a paid lead handed to a competitor.
→ Fix the site. A slow, confusing, or no-mobile site burns the clicks you paid for before the visitor ever calls.
→ Follow up on estimates. A single reminder closes jobs you already paid to quote — at zero added acquisition cost.
→ Build organic. SEO and reviews bring leads with no per-lead cost, which pulls your blended CPA down month over month.

When you should not chase a lower CPA

A low CPA isn't the goal — profit is. Don't optimize it when:

• You can profitably take every job you can get. Then spend more and grow; a higher CPA that fills the calendar wins.
• Your volume is tiny. With 5 customers a month, the number swings wildly and tells you little — watch the trend, not one figure.
• Cutting CPA means cutting your best channel. Cheap leads that don't close cost more than expensive ones that do.

If you're already booked solid, you don't need cheaper leads — you need to raise prices or hire. CPA is a tool for businesses that want more work and want to know what it costs to get it.

Where we fit

You can't lower CPA if you can't see it. Our $597 plan wires lead attribution into your site, so you know which page, ad, or search produced each call. From there, the conversion fixes above — fast capture, a clean site, follow-up — do most of the work.

The site plus AI lead capture starts at $249/month; attribution and the monthly SEO engine come at $597. See SEO for home services, the AI receptionist, or our breakdown of local SEO cost and whether local SEO is worth it.

We don't post stock testimonials. On a 15-minute call we screen-share the real dashboards behind our own businesses — live leads, rankings, and the exact page that produced each one. See the proof →

Common questions

CPA vs. CPL — what's the difference?

Cost per lead is what you pay for someone who contacts you; cost per acquisition is what you pay for someone who buys. CPA is always higher, and the gap is your booking rate. Improve the booking rate and CPA drops without touching spend.

How does CPA relate to lifetime value?

Lifetime value is everything a customer pays you over time. As long as CPA stays comfortably below it, paying to acquire is profitable. Recurring businesses can pay far more per customer than one-off ones for that reason.

Should I cut ad spend to lower CPA?

Usually not. Cutting spend without fixing conversion just gives you fewer leads at the same CPA. Fix the site, the callback speed, and the follow-up first — that lowers CPA and keeps the volume.
