Most pressure washing contractors track revenue. Few track the two numbers that actually tell you if your business is healthy: LTV (lifetime value) and CAC (customer acquisition cost). Once you know your LTV:CAC ratio, you stop guessing on marketing spend and start making decisions that protect your margins.

The Quick Answer

A healthy LTV:CAC ratio for a pressure washing business is 4:1 to 5:1. That means for every dollar you spend acquiring a customer, you need to earn four to five dollars back over their lifetime. Here's what the numbers look like in practice:

Conservative LTV (1 job/year x 3 years at $300/job): $900
Moderate LTV (1.5 jobs/year x 4 years at $400/job): $2,400
Google LSA CAC: $80-$250 per booked job
Facebook Ads CAC: $40-$200 per booked job
Referral CAC: $0-$30 (soft costs only)

At a $900 LTV and $150 Google LSA CAC, your ratio is 6:1 -- well above the minimum. But if your CAC climbs past $300 and your LTV stays flat, your margins disappear fast.

How to Calculate Your LTV

The formula is straightforward:

LTV = Average Job Value x Jobs Per Year x Customer Lifespan (years)

Most residential pressure washing customers book once a year. In humid climates like the Southeast, twice a year is common. Here's how the numbers play out:

$300 x 1 visit/year x 3 years: $900 LTV
$400 x 1.5 visits/year x 4 years: $2,400 LTV
$450 x 2 visits/year x 5 years: $4,500 LTV

Notice how a small bump in visit frequency and customer lifespan creates a massive jump in LTV. That's why converting one-time customers to recurring annual contracts is the highest-leverage move in a pressure washing business.

How to Calculate CAC by Channel

CAC is what you actually spend to land one booked job -- not just a lead. Divide your total channel spend by the number of closed jobs that came from it.

Google LSA: $15-$45 per lead, 25-45% close rate = $80-$250 CAC
Facebook / Instagram Ads: varies heavily by creative = $40-$200 CAC
Google Search Ads: $40-$120 per click = $130-$400 CAC
Angi / Thumbtack: $25-$85 per shared lead, 10-25% close rate = $100-$500 CAC
Referrals: near-zero spend, 60-80% close rate = $0-$30 CAC

Google LSA consistently outperforms other paid channels for pressure washing. Across $6.72M in tracked LSA spend for exterior cleaning trades, the average cost per lead ran $15-$45 -- well below the $53 home services average.

What Your LTV:CAC Ratio Means

Here's how to read your number:

Below 3:1: You're spending more to acquire than you recover. Unsustainable at scale.
3:1 to 4:1: Acceptable but thin. One slow season and it hurts.
4:1 to 5:1: Healthy. Room to invest in growth and weather slow months.
Above 8:1: You're underinvesting in marketing and leaving growth on the table.

There's also a payback period to watch: how many months until you earn back what you spent to acquire a customer. A $150 CAC against a $350 job booked once per year means a 5.1-month payback. If payback stretches past 6 months, cash flow becomes the constraint even when the ratio looks healthy.

How to Push LTV Higher

LTV is the more powerful lever. Here's what actually moves it:

Convert one-timers to annual contracts. A seasonal reminder at 10-11 months locks in the rebooking before the customer searches for someone else.
Bundle services per visit. House wash + driveway + deck at $600-$800 per visit beats three separate $250 jobs on LTV math and saves you drive time.
Upsell on every job. Soft-wash roof cleaning ($0.30-$0.60/sq ft) and concrete sealing ($0.10-$0.30/sq ft extra) increase average job value with no additional drive time.
Build a referral program. Referred customers close at 60-80% and cost almost nothing to acquire. Every referral raises your effective LTV:CAC ratio across the whole business.

How to Pull CAC Down

You don't need to cut marketing spend to lower CAC -- you need to spend smarter:

Lead with Google LSA. At $80-$250 CAC for pressure washing, LSA consistently beats search ads and marketplace platforms.
Fix your Facebook creative. CAC on Facebook ranges from $40 to $200 based almost entirely on ad creative quality. A strong before/after video can cut your CAC in half.
Stop paying for shared leads. Angi and Thumbtack charge $25-$85 for leads that go to 3-5 contractors at once. Close rates of 10-25% produce the worst ratio of any paid channel.
Build your Google Business Profile reviews. Better reviews improve both organic rankings and LSA ad rank, lowering your effective CAC over time without increasing spend.

Bottom Line

Track your LTV and CAC for every marketing channel. Target a 4:1 to 5:1 ratio and CAC payback under 6 months. If you're only tracking revenue, you could be growing fast while your margins quietly shrink -- and not see it coming until it's too late.
