Average Revenue per Customer is how much you earn from a single customer. For one-time sales, it's the deal value. For recurring revenue, use the customer lifetime value (LTV).

Formula: Revenue per Customer=Total RevenueNumber of Customers\text{Revenue per Customer} = \dfrac{\text{Total Revenue}}{\text{Number of Customers}}

Where to find it: Your CRM (HubSpot, Salesforce), payment processor (Stripe), or accounting software. Use a 6-12 month average for accuracy.

Example

$500,000100 customers=$5,000 per customer\dfrac{\$500{,}000}{100 \text{ customers}} = \$5{,}000 \text{ per customer}

Tip: If customers make repeat purchases, use lifetime value instead of first-purchase value. A customer worth $500 upfront might be worth $2,000 over their lifetime.

Cost to Deliver is everything it costs to fulfill the service or deliver the product for one customer. This is your per-customer cost, not monthly totals.

Include: Labor/time to deliver, materials, software licenses, subcontractors, onboarding costs, and customer support.

Don't include: Marketing spend, office rent, or salaries not directly tied to fulfilling orders. Those are overhead.

Typical ranges

Professional services: 40-60% of revenue

SaaS / digital: 10-30% of revenue

Home services: 30-50% of revenue

Lead-to-Customer Close Rate is the percentage of leads that become paying customers.

Formula: Close Rate=New CustomersTotal Leads×100\text{Close Rate} = \dfrac{\text{New Customers}}{\text{Total Leads}} \times 100

Where to find it: Your CRM pipeline reports, or divide new customers by total leads over the same period.

Typical ranges by source

Referrals: 20-50%

Google Search Ads: 5-15%

Facebook/Meta Ads: 2-10%

Cold outreach: 1-5%

Tip: Track close rate by channel. Google Search leads often close at 3-5x the rate of social media leads because they have higher intent.

Target Profit Margin is the percentage of revenue you want to keep as profit after all costs, including marketing.

Set this to 0 to find your absolute maximum CPL (break-even). Any value above 0 reduces your CPL target to ensure you're actually making money.

Typical targets

Professional services: 15-25%

SaaS: 20-40%

Home services: 10-20%

Agencies: 15-30%

This field is optional. Leave it at 0 to see the maximum you could possibly spend per lead.

What is Target CPL?

CPL stands for Cost Per Lead. It measures how much you spend to acquire one potential customer through your marketing efforts. If you spend $5,000 on ads and generate 100 leads, your CPL is $50.

Target CPL is the maximum you should spend per lead while still hitting your profit goals. It accounts for your revenue per customer, delivery costs, close rate, and desired profit margin.

Knowing your target CPL is critical for lead generation businesses because it turns a vague question (“Are my leads too expensive?”) into a concrete, personalized answer. A $200 CPL might be a steal for a business with $10,000 deals and a 20% close rate, but devastating for one with $1,000 deals and a 5% close rate.

The formula

Target CPL=(Revenue−Delivery Cost−Revenue×Margin%100)×Close Rate100\text{Target CPL} = \left(\text{Revenue} - \text{Delivery Cost} - \text{Revenue} \times \frac{\text{Margin\%}}{100}\right) \times \frac{\text{Close Rate}}{100}
Rev−Cost−Profit\text{Rev} - \text{Cost} - \text{Profit}

How much of each sale is available for marketing costs

×Close Rate100\times \dfrac{\text{Close Rate}}{100}

Scales down to a per-lead amount based on how many leads convert

Worked example

Revenue

$5,000

Delivery Cost

$2,000

Close Rate

20%

Profit Margin

20%

Profit per Customer=$5,000−$2,000=$3,000\text{Profit per Customer} = \$5{,}000 - \$2{,}000 = \$3{,}000
Target Profit=$5,000×20%=$1,000\text{Target Profit} = \$5{,}000 \times 20\% = \$1{,}000
Available for Marketing=$3,000−$1,000=$2,000\text{Available for Marketing} = \$3{,}000 - \$1{,}000 = \$2{,}000
Target CPL=$2,000×20%100=$400\text{Target CPL} = \$2{,}000 \times \frac{20\%}{100} = \boxed{\$400}

This means the business can spend up to $400 per lead while maintaining a 20% profit margin. At a 20% close rate, they need about 5 leads to win one customer, paying up to $2,000 in total marketing cost per customer acquired.

How to Calculate Your Target CPL

Revenue per Customer

Revenue=Total RevenueTotal Customers\text{Revenue} = \dfrac{\text{Total Revenue}}{\text{Total Customers}}

CRM: HubSpot, Salesforce, or Pipedrive deal reports

Payments: Stripe or QuickBooks average transaction value

Manual: Total Revenue / Total Customers

Use lifetime value if customers buy more than once. A one-time $1,000 sale with 3 repeat purchases over 2 years = $4,000 LTV.

Cost to Deliver

Add up everything it costs to deliver your product or service to one customer.

Direct labor and time

Materials and supplies

Software and tools

Subcontractors

Onboarding and support

Payment processing (~2.5-3%)

Common mistake: forgetting the time cost. If you spend 10 hours on a client at $100/hr, that's $1,000 in delivery cost.

Lead-to-Customer Close Rate

Close Rate=New CustomersTotal Leads×100\text{Close Rate} = \dfrac{\text{New Customers}}{\text{Total Leads}} \times 100

CRM: Pipeline conversion report (lead → customer)

Manual: Count new customers / count new leads over 90 days

Calculate this per channel. Google leads and Facebook leads almost always have different close rates.

Target Profit Margin

The percentage of revenue you want to keep as profit after everything, including lead acquisition.

Set to 0% for break-even (max possible CPL)

10-15% for conservative growth

20-30% for healthy profitability

30%+ for premium, high-margin businesses

Start with 20% as a baseline. You can always adjust once you see what CPL you can realistically achieve in your market.

Frequently Asked Questions

Cost per lead is how much you spend to acquire one potential customer. It includes all marketing costs (ad spend, content creation, agency fees) divided by the number of leads generated. If you spend $5,000 on ads and get 100 leads, your CPL is $50.
It depends entirely on your deal value and close rate. A $500 CPL is great if your average customer is worth $50,000 and you close 20% of leads. The same $500 CPL is terrible if customers are worth $2,000 and you close 5%. That's why target CPL matters more than generic benchmarks.
CPL (Cost Per Lead) is what you pay to get a lead. CPA (Cost Per Acquisition) is what you pay to get a paying customer. CAC (Customer Acquisition Cost) includes all sales and marketing costs per customer, not just ad spend. They're related: CPA = CPL / Close Rate. CAC is the broadest measure and includes salaries, tools, and overhead.
Close rate has a massive impact. If your close rate doubles from 10% to 20%, your target CPL doubles too, because each lead is twice as likely to become a paying customer. This is why investing in your sales process and lead qualification can be more effective than trying to get cheaper leads.
No. Cheaper leads are often lower quality. A $20 lead that converts at 1% costs you $2,000 per customer. A $200 lead that converts at 25% costs you only $800 per customer. Focus on cost per acquisition (CPA), not just CPL. The best strategy is finding the CPL sweet spot where lead quality and volume both work.
Focus on what moves the needle most: improve your landing page conversion rate (this directly lowers CPL), test different ad creatives and audiences, invest in organic channels (SEO, content, referrals) which have 30-50% lower CPL than paid, use retargeting to re-engage warm audiences at lower cost, and qualify leads earlier to focus spend on higher-intent prospects.
Calculate your target CPL separately for each channel. Google Search leads might close at 15% while Facebook leads close at 5%. This means you can afford to pay 3x more per Google lead. Running one blended calculation hides which channels are profitable and which are losing money.
